Probably, yes. May 16, 2006 6:08 AM

Electricity that is generated by burning of fossil fuels is obviously dangerous.  Pollution, environmental degradation, global warming, etc.  We are possibly already past the point of no return in the regards to the damage that we have caused by burning fossil fuels.

It takes a long period of time to build a nulear power plant from scratch.  We will not be able to get nuclear plants on line in a short period of time. I say the sooner we build any alternative sources of electricity,the better.  Wind, solar, hydro-electric sources have limited capacity at this time.  I hope that the efficiency of these sources can be increased and become more practical.

Chernobyl was the biggest nuclear disaster known to date and so far the environment in the area, devoid of human impact, appears to be in better condition than the environments in the areas of coal burners and the like.

I dont have the answer for the possibility of nuclear WMD's being proliferated because of the increased availability of radioactive materials.

I do believe that we can safely store and recycle radioactive wastes without causing environmental damage if the public demands rigid and continuing safety oversight.

Because of the lack of other efficient electrical sources; I unfortunately believe that nuclear power is our only solution for providing the energy that will be required in the near future.

anonymous Nuclear Waste in transit May 17, 2006 4:27 PM

There are a number of other issues in regard to the transit of these materials, be it from outside of the State or during intrastate transfers.

(i)                   Consideration and respect needs to be shown to those suburbs, towns, regions and Local Government areas that have declared themselves Nuclear Free and do not wish to have these substances transported across their boundaries.

 

(ii)                 The method of transfer also needs to be addressed. It is not simply a question of putting this material onto the back of a truck and dispatching it to a destination as with other goods and materials. The storage containers, the safety of those along the route and the security of the shipments will need close scrutiny.

 

Other means of dealing with the radioactive waste  needs to be investigated. Our consumer orientated society is addicted to the “use once and throw away” mentality. What of the potential for reharnessing the energy contained in the wastes? More emphasis should be placed on recycling nuclear waste to meet future energy needs.

looks really familiar ... May 17, 2006 8:17 PM

... a bit of "deja vu", eh Megan?

Why was responsible recycling not considered an option? In 1979, the first general manager of the United States’ Atomic Energy Commission, Carroll Wilson, explained. ‘It was not glamorous; there were no careers; it was messy; nobody got brownie points for caring about nuclear waste.’ (IEER, 1986.)

Anti-nuclear, arms control, and environmental groups sought to eliminate the reprocessing option for commercial spent fuel by insisting on disposing of it as soon as possible. (IEER, 1986.)

It was easier and cheaper in 1979 to cut down forests rather than recycle paper and timber; to strip mine bauxite rather than recycle aluminium; to dump waste water into the sea rather than recycle it for irrigation and re-greening projects; to burn old tyres rather than recycle them into shock-absorbing surfaces and safety barriers and flood and landslip retention schemes.

What makes radioactive wastes so dangerous is the very thing that made the source materials so valuable: the intrinsic radioactivity. Dumping these wastes, whether individually or collectively, because it is easier and cheaper only perpetuates the same irresponsible attitude we once held for all things. As a society, we still lack the wisdom and the political will to apply responsible principles to radioactive wastes.

There is an ancient saying that we do not inherit the world from our parents, we borrow it from our children. It will fall to our children to address the unexplored option and responsibly recycle and beneficially use the contaminants we continue to produce.

Reprocessing of nuclear fuel for standard power plants can only go so far ... but these are high temperature fast burn plants ... no one has even looked at low-med temp long burn hybrid plants as potential for 'heat bank' applications ... or for low yield electricity generation (ie the equivalent of standard solar collectors or lead-acid battery banks) ... imagine the isolated communities (which already run on 24 volt DC power) having enough to grow into sizable communities ... and the power is ticking over 24/7 for about ten thousand years ... longer than any civilisation has lasted ...

We are still too used to living "fast and loose" with our power, water, and environment ... especially here in Australia ...

Nuclear isn't a 'small scale' option because so much effort has to go into making it safe. Everything in the imediate vecintiy becomes radioactive. You cannot make a small nuclear battery because the reactions generate heat. You need a boiler, a steam turbine and a generator to then get electricity.  [ send green star]

I made no mention of scale ...

and, not everything becomes radioactive ... there are elements and compounds that act as "dampers" ... they absorb radiation without themselves becoming radioactive ... that's why nuclear power generators can be built at all ... and why nuclear fuel eventually becomes "spent" ... the ratio of active emitters to absorbers becomes too low ...

I'm pretty sure those absorbers do become radioactive themselves. And they do not absorb all the radiation. A nuclear plant uses two luiquids to transport the heat. The first - a lquid metal I think, absorbs the radiation and heats up and is then cycled to a heat exchanger where it is used to boil water before being sent back into the nuclear reactor bit.

Yes, but you still need to get something rotating. You can't just plug the axle of the generator into a block of radioactive material.

Because the energy is already in the form of mechanical energy. You can just plug the axle of the generator into the trubine, though a few gears would help.

"As nuclear power generation has become established since the 1950s, the size of reactor units has grown from 60 MWe to more than 1300 MWe, with corresponding economies of scale in operation. At the same time there have been many hundreds of smaller reactors built both for naval use (up to 190 MW thermal) and as neutron sources, yielding enormous expertise in the engineering of deliberately small units."

Web coverage of the implosion: http://www.kptv.com/ look for Trojan Nuclear plan implosion on the left side.

Bringing an end to yet another horrible failure of Enron/PGE

PGE to implode Trojan tower at end of May 03:34 PM PDT on Sunday, May 14, 2006By SARAH SKIDMORE, AP Writer 

RAINIER, Ore. -- One of Oregon's most recognizable and controversial landmarks is about to come down in a cloud of dust.
Portland General Electric plans to implode the massive cooling tower on Sunday at its defunct Trojan Nuclear Power Plant, northwest of Portland.
 
The 499-foot tower will be reduced to a 41,000-ton pile of rubble by about 2,000 pounds of explosives. It's Oregon's first and only nuclear power plant.
 "The nuclear history in Oregon is a troubled one at best," said David Stewart-Smith, retired assistant director for the Oregon Department of Energy. "It started off as the new and exciting technology but didn't pan out very well."

Trojan opened in 1976 and was beset by problems until it closed in 1993. 
The plant was built near a geological fault in the Columbia River in the '70s. In 1989, the Nuclear Regulatory Commission fined PGE for debris in two sumps that could have prevented its emergency core-cooling system from working in a disaster.

Its ongoing problems led many to believe it was the inspiration for the error-ridden nuclear plant in "The Simpsons," a creation of Portland-born Matt Groening. (Groening's representative said it is not.)
The plant rarely ran at full capacity, often stopping operations when there was a major snowmelt because PGE could buy excess hydroelectric power from nearby Bonneville Dam cheaper than the power plant could make it. And the market for energy was changing, making Trojan's operation more labor intensive and expensive than other alternatives.So after steam tubes cracked and leaked radioactive gas into the air, PGE and regulators decided it made more financial sense to close the plant than to continue operations. Built for $460 million in the 70s, Trojan was approved to be decommissioned at a $429 million total cost.

Full decomissioning will take several decades. Remaining buildings will be destroyed gradually through 2008. And federal regulators are trying to develop a national repository where the spent radioactive fuel rods can be kept permanently. The rods are now kept in concrete casks sitting above ground and are anticipated to be moved in 2024. 
The tower implosion, however, has garnered most of the attention.

"It's going to be fun to have a picture of this," said Mark McDougal, an attorney and environmentalist involved in the long-running fight against Trojan. Anti-Trojan activists were concerned about the health risks and radioactive waste from a nuclear power plant. Environmental activists brought several initiatives to voters and petitions to regulators to close down the plant. People protested Trojan on numerous occasions. Through legal and political wrangling, activists managed to block creation of at least one other nuclear power plant in Oregon.

For these activists, the implosion is a long-awaited cause for celebration. McDougal and others are having a party after the event, complete with cooling tower-shaped pinatas. But in the economically struggling timber towns that surround Trojan, there are mixed feelings about May 21. At nearby Goble Tavern, once a watering hole for Trojan employees, there will be a "Trojan Implosion" party with live music and fire dancers.

"It's kind of bittersweet," said Shayla Baslington, an area resident who will be at the Goble party. "You've wanted it gone for years, but now you are used to it as a landmark." 
Some locals and former workers said the event may be a sad reminder of the plant's heyday. The power plant brought jobs and major tax revenue to Rainier and surrounding areas. At its peak, Trojan had 1,200 employees in a city with roughly the same number of residents. Its closure was devastating, said Gary Gettman, who was a supervisor of quality control inspections at Trojan and now pumps gas to make up for the retirement money he lost after the fall of Enron, which used to own PGE. "It's still a topic of conversation -- how good it used to be -- good for us, good for the community," Gettman said. Some people want the tower to stay as a reminder. But Controlled Demolition Inc., the contractor, said it is better to bring the tower down now than wait until it becomes decrepit.

The tower is now an empty shell waiting to be destroyed. The machinery once inside is gone. Workers have drilled more than 3,000 holes in its exterior, where the explosives will be placed. The firm said it will take about 14 seconds to bring the tower down.
The casks where the fuel rods are stored will not be affected by the blast, according to Controlled Demolition.
The implosion is tentatively scheduled for 7 a.m. PDT. PGE and the contractor said people wanting to catch a glimpse of the action can get the best view on television. Road, air and water space surrounding Trojan will be restricted.

Nuclear Accidents??? July 30, 2006 5:35 AM

Good Morning Free, et al

Wow, the only thing we need to do with nuclear is to figure out what to do with the waste.  There have been far too many accidents involving the inefficient electric generating plants.  How do you spell Chernoble? Three Mile Island? and how many of these facilities are built on fault lines?

We need to decentralize electric power.  Create local generating plants for the neighborhood...it doesn't have to travel miles to 100's + miles with loss of energy to increase the costs.  How many executives are we paying for when we pay for the centralized power???  How many Enrons are out there? 

Solar, photo-voltaic, wind, electro-magnetic, hydrogen, bio-diesel, and ethanol, etc., are some of the options that should have and can be the focus for our needs now.  Why go down the most dangerous path (nuclear) when there are other non-toxic less expensive opportunities.  We need to advance the use of these other methods for decentralizing the power.  The options could focus on 12-24 volt appliances and lighting. 

Don't let the slick sales people convince you that what they are selling, expensive nuclear waste is their way to go. It is their way to go.  Don't buy into it.  BS!!! Cow poop... dung!  We need to reward (R & D) the newer alternative methods, not the old waste methods.  Buy into their pitch and they'll be laughing all the way to the bank as we are crying in our spoiled soup, nuclear waste. 

Have you checked your radiation level lately???  Chlorophyll will help to neutralize radiation poisoning, xrays, etc.

I'm not sure decntralising power will increase efficiency. Power plants get more efficient as they get larger. Power can be transported long distances at very high voltages without a lot of losses. It is when you get down to low voltages (and therefor higher currents) that you get losses.  [ send green star]

and as neucler instlations age i am convinced that the powers that be take calculated risks once maintanance costs get higher that economical. afterall building a new one is so epensive the risk of running a les than safe instlation becomes attractive.

There does not appear to be any way to make nuclear energy safe, although the danger can be somewhat minimalized. If we look at actual fatalities related to nuclear energy, we find the number is relatively low, especially when compared to coal-related deaths. (Here we must add the human cost of mining, including both mine accidents and black-lung disease, not to mention global warming and smog).

Nuclear energy does present the POTENTIAL for major disaster, both in the plants themselves (design failure, human error, terrorist attack) and due to wastes. With a half-life of about 90,000,000 years, there is no way we can guarantee that spent uranium can be stored adequately.

Making nuclear power relatively safe also makes it outrageously expensive. It was the expense involved, and not safety issues per se, that caused the nuclear industry in the United States to cease construction of new plants in the 1980s.

As Spencer notes, concentration of power production in huge plants implies centralization. Distribution of electricity over a territory as large as the United States then requires the construction of a costly network of high power lines. Centralized production in the U.S. today is basically a result of Reagan's deregulation of the industry, an industry which still has not invested in improving its distribution network. These two factors are the main cause of the recent power shortages in Queens and California.

Renewable energy sources, such as solar, wind, tidal, and geo-thermal tend to be small scale. They do not easily fit into a nation-wide distribution network, but are better suited to addressing local needs.

No method of generating electricity is without its downside, but alternatives to coal, petroleum, and nuclear power offer many advantages over the first three.

There was a show on TV about this last night. It looked at Yukka mountain and how they still haven't built the long term storage facility they had promised. Now that Las Vegas has lots of money they are holding it up. So basically the US is still producing nuclear waste but hasn't found a storage solution. They are also considering Russia and Australia. Yukka mountain is apparently porous, but there is no water now. The problem is there could be a lot of water there in the distant future, flushing the waste through. The US hasn't built any new plants since thre three mile island disaster (78?), but it may start again soon.  [ send green star]

safe nuclear energy November 27, 2006 11:02 PM

nuclear energy can only be safe when it is generated at a considerable distance from anything living. If a way was found to have a reactor far enough from earth so that a meltdown would be safe then and only then is nuclear a viable option. Chernobyl is used as reason for why we shouldn't use nuclear rectors o earth. However, it is worth noting that the Chernobyl incident was benign compared to what would have happened if the nuclear material had melted down into one of the water tanks under the reactor.  [ send green star]  [ accepted]
 
distance November 27, 2006 11:11 PM

That's an interesting point. I've heard an idea, probably far-fetched, of sending solar panels into space to collect radiation, and then beaming the energy to earth via microwave beams. The point was that solar energy is more concentrated when it hasn't had to go through the atmosphere. It probably wouldn't make sense given the costs (economic and environmental) of getting the solar panels up there and maintaining them. But it may make sense for nuclear. Although if the plant exploded you may still end up with radiactive material getting into the atmosphere, but I would imagine that if you could get it far enough away then even if it did explode it would not end up on earth. And if it broke down and got left up there the radiactivity would decay by the time it fell from the sky.

But it would still be a lot cheaper to find a safe way to do it on earth.

that any form of nuclear management is dangerous is undissputable. finally it is the economics of the whole deal that makes the project. for example if we were to put a whole load of nuchear plants plumb in the middle of thevast sahara desert it would be relativly safer for human beings.. but the cost of then carrying the power would make it impossible for a break even. thus i think we are saddled with nuclear power until some completly new technology comes through making fossil fuel reduntant. and this is unlikely to happen as oil companies wil not allow any such research  [ send green star]  [ accepted]
 
Nothing is Safe December 04, 2006 10:55 AM

Nuclear is not safe.  Coal or any other fossil fuel is not safe.  And so on, they're not safe.  There are no exceptions, everything in life has risks.

The best we can do is minimize the risks and the costs.  And that includes all the "externalized" costs too.  The externalized costs of oil include the massive military expenses - in money and in lives - needed to keep the oil flowing.  Our mideast adventures may result in a devastating war with multi-millions killed and perhaps whole nations destroyed, all traceable back to our use of oil.

Plus of course the spectre of global warming, we have no idea how severe it may affect life on earth as we know it.  It is neither ethical nor moral to for one species - humans - to risk extinction of thousands of other species just so we can keep our gadgets going.

In that light, nuclear may not look so bad.  One, it causes no global warming.  Two, it doesn't impinge on the lives of people on the other side of the earth who get no benefit from our electricity. 

Chernobyl was bad, but tiny compared with a mideast war or even the damage associated with 200 years of coal in this country.

In my view, nuclear is risky but it's the best option.  Doesn't it make sense for those who benefit from the electricity be the ones who take the risk?

Yes, it is safe... March 02, 2008 11:07 AM

I just joined the group a few moments ago.  I realize that this was an old topic of discussion, but it is the one I wanted to chime in on.

I grew up in a nuclear family.  My father was the General Manager of one of hte nuclear power plants (and later VP), and I spent a little over 9 years in the Navy as a reactor operator/reactor technician.  I also spect 6 years after that working at OSU with Westinghouse on their latest reactor plant model.

Not all reactor designs are safe...that much is obvious to most everyone.  The design used by the Soviets was an accident waiting to happen, one that the IAEA warned them about, and which ultimately came to pass.  That design used graphite as the moderator (the substance that slows fast neutrons from fission to become thermal neutrons capable of causing another fission, at least for U-235).  The design used a separate medium (a gas) for the removel and transfer of thermal every from the core to the rest of the system.  This alone was inherently unsafe, in that a loss of coolant accident (LOCA) would not in itself shut down the reactor.

The US uses PWR, or Pressurized Light-Water Reactors.  In these, the moderator and the coolant are one in the same.  A LOCA removes the ability to slow down the neutrons and therefore greatly slows the fission rate (it never stops, but it can be slow enough to be negligable).  US plants also have a containment dome made of reinforced concrete that can withstand intense earthquakes and even a direct hit by a 747 (among others).  If the Soviets had used a containment dome (as the IAEA recommended) no one would have been hurt, contaminated, or irradiated by the accident.  Unfortunately for many that was not the case.

The Electric Power Research Institute (EPRI) worked with the Nuclear Regulatory Commission (NRC) to get them to finally stop jerking around the utilities.  All through the 60's and 70's the NRC, at the insistance of the politicians, would constantly make changes to the requirements for the reactor,s team, and associated systems.  These changes caused delays in construction, overruns in budget from redesign, and in many cases, caused the utilities to simply give up (take WPPSS as a prime example).

There is a prevailing, albeit incorrect, assumption that it is possible to make something absolutely safe.  Not possible.  Not with cars, not with airplanes, not even bicycles and bathtubs.  And not with nuclear reactor plants.  It is a reasonable and rational compromise between cost and acceptible risk.  That has been achieved with the reactor plant designs.  Event TMI, though the core was damaged and no longer usable, did not hurt anyone, nor was there any increase in the natural background radiation level anywhere around the plant.  None.

Westinghouse, as well as others like GE, have developed advanced, passive, safety systems.  The plant design we worked on at OSU in the 90's was AP600 (it had a 600 MW output).  The safety systems were all passive, meaning that nothing external had to happen in order for the safety systems to function: no pumps required to turn on, no diesels required to start up, nada.  We tested every conceivable LOCA and not once was the core uncovered or allowed to overheat.  In fact, the operations staff could literally walk away for two weeks and no damage would occur.

Even after we completed the testing required by the NRC for Westinghouse to obtain the license, we did further testing at the request of the NRC to see what it would take to achieve core damage.  We couldn't do it.  Not because we weren't smart or clever enough, but because the system was so well designed that the core always stayed covered with water, and that water always removed the heat generated.

The Westinghouse design also called for a modular construction of the entire site.  This construction could be competed in five years...not the 10-12 that previous sites required.

I urge each of you to check out the new advanced plant designs.  Just Google AP600 (or AP1000, the latest version).  Nuclear power generates no greenhouse gases...just steam (well, water vapor, to be more correct).  Also, the mere fact of mining uranium means that it will not be in the ground decaying into radon, which is a problem.  These palnts have no ill effect on their environment...not like oil and coal plants.

The last problem is the waste.  Storage is not the solution...it never was.  The solution is reprocessing of the fuel material.  The spent fuel is never all spent.  Because of the buildup of other fission products (like Xe-135), it is not possible to actually use up all of the loaded fuel.  Reprocessing will allow for that unspent fuel to be used elsewhere...recycling.

The spent fuel also includes amy useful radioisotopes that can be used in medice and various forms of research.  These can be extracted and sold, helping to defray the cost of the reprocessing.

After reprocessing, the amount of high-level waste material would fit under a card table from one-year's operation of a large reactor plant.  Turn this into glass and store it somewhere.  Being glass it cannot and will not erode or corrode, and therefore will never enter the groundwater system.

yes the  American nuke  navy  has  for  years, but  it  is  very  expensive...and  the  total  costs  IE  long term storage of waste  are  unknown
