Not sure if worthy of a new topic, but there's some coverage of and appetite for Small Modular Reactors in the UK.

Quote:
Leading British businesses and universities are pinning their hopes on home-grown small reactors to help revive the country’s stalled nuclear power station programme.

Delays continue to plague efforts by foreign companies to build the country’s first plants in a generation. Some 400 construction workers have been laid off by EDF, which is building one at Hinkley Point, as the French company and its Chinese partners haggle over electricity prices with the government.

Small Reactors will not solve any fo the problems faced by Hinkley Point - which are primarily political in nature.

PRISM, a new fast, small, modular design has been offered to the UK. With availability of reprocessed plutonium, it could be the best new generation offer to them, After trials it could be built locally in numbers.

Trials that will take ten years, after the end of a ten year construction period.

20 years is too long to wait.

These things took much shorter at beginning of nuclear era. Get back in that spirit.
Till then, continue with AGR.

There hasn't been an AGR built in 30 years.
Thatcher sold off/out the British nuclear industry and bought an off the shelf PWR.

Even the edf plans to extend the life of existing AGRs. They could hold out till the new engineers are trained.
Th-Pu MOX could be used in the AGR which always utilized reprocessed fuel.
PRISM remains an option once again after fast reactors have been being given up once. Let others develop it. If others can make bad PWRs, they could hopefully make better fast reactors.

It seems to be moving forward:

The econuts have gone into meltdown:

And there is a large amount of anti-Chinese nonsense being whipped up.

Nevertheless, an almost guaranteed 10% rate of return is pretty good!

If you look in the comments of that second article you can see me under the name 'TheMadChemist'.

Single handedly mounting a defence of nuclear power and explaining why pumping huge amounts of money into solar and wind is not a great idea given our current position.
(January 2010 we had a several week calm that reduces wind turbine capacity to about 0.5% of nameplate)

Not single handedly. Many of the commentators are very well informed. Of course, there are some who still down't understand the difference between capacity and output.

Tens of billions of euros/ponds/dollars is a lot of money to put in one reactor. The Brits would have done better to go for 100MW Prism modular units. Fact remains that no EPR is working yet. Prism is on equal footing. Apparently, the Westinghouse seem to be willing to build one and run it for power costs. The cost of power can decide the further decisions.

Like virtually all power stations in the UK, apart from Sizewell B, Hinkley Point C is two reactors.

Agreed that current estimate of one unit of Hinkley costs 'only' 9 Billion Pounds, amounting to 5500 ponds per kW. The Indian 500MW PFBR nearing completion costs all of 600 million pounds @ 1,200 ponds per kW. Prism at four times the cost would be beneficial to UK. I am sure the Westinghouse could build a 100MW unit for half a Billion and provide power at lower rates than the French.

The Westinghouse AP1000s at Moorside are projected a lower breakeven price of about £88/MWh.

But the big killer here is capital repayment rates. Even with the absurd costs of EPRs it would be viable with the current 30 year gilt interest rate of 2.54%
