Re: Traveling Wave Reactor

Some 200,000 to 300,000 tonnes of used nuclear fuel is lying around. More is being generated. A molten chloride Waste digester is the need of the times, not only as Waste digester but as the main line power plant.

Re: Thermal Spectrum Advantages?

As a counterpoint, fast reactors are more compact. The fuel waste is less. The fertile fuel is also burnt in higher proportion. Earlier Russian nuclear submarines used fast reactors.

Re: Top 11 Problems Plaguing Solar And Wind Power

Cost effectiveness of any product or technology varies with time, place and circumstances. This fact should however be applied judiciously. Subcidies for new technologies are a case in point. They should not be continued for too long. Some densely populated areas have been mentioned for solar or win...

Re: Nuclear Ship Propulsion

With such large numbers in consideration, it is preferable to apply the tractor trailer idea. We could have a nuclear tug designed for traction and a trailing vessel designed for streamlined minimum resistance. The raft trailer could have a smaller battery for housekeeping, charged by the tug engine.

Re: U.S.-Russia Plutonium Management and Disposition Agreement

Plutonium thorium MOX will use more of plutonium to begin with and run longer. Unfortunately it has not moved beyond theory and experiments so far. It would also produce U233, the better reactor fissile.
If the US have excess fissile now, it should be utilised this way for optimum benefit.

Re: Sellafield power generation project (Moorside)

The UK should build their own plants if cheaper alternatives are not available. If the newer designs are uneconomical, older AGR should be continued with.

Re: News from the German department of I-told-you-so

The worst of coal power is suspended particles and sulphur. They could gasify the coal and clean the gas of these poisons. This gas could be used in place of natural gas to deal with intermittency. For longer storage they could liquify it to ethanol/methanol/ dimethyl ether. For cleaner extraction, ...

Re: Unique Non-nuclear Applications of Th and U

Even the older non-nuclear applications of uranium and thorium have been given up by raising the bogey of radioactivity. Uranium salts are no longer used to Colorado glass. Thorium mantles have also been given a bad name.

Re: U.S.-Russia Plutonium Management and Disposition Agreement

Why is nuclear power milked for profits instead of slaughter in initial stages? NRC starts off the matter by regulating the projects into insolvency.

At least the existing plants will be used for their full lives. Have they thought of storage to cover the intermittency of generation?
