U.S.:  Record Nuclear Shutdowns Seen Boosting `Pummeled' Natural Gas
More U.S. nuclear reactors will close for refueling this spring than at any time in nearly two decades creating a power shortage that may lift beaten-down natural gas.

Operators plan to shut 34 reactors, or more than a third of nuclear generating capacity, to replace fuel rods from March through May, according to Michael Rennhack, president and chief executive officer of www.NukeWorker.com, a website that advertises jobs in the sector. That would be the most for the time of year in data going back to 2000, according to the U.S. Nuclear Regulatory Commission and projections from Rennhack.

The closures may be good news for gas, the worst performer in the Bloomberg Commodity Index as generators that burn the fossil fuel run harder to make up for the nuclear shortfall, according to Kyle Cooper, director of research with IAF Advisors in Houston. The power plant and heating fuel has tumbled about 28 percent this year as weak demand amid unseasonably warm weather has allowed a glut in supplies to persist.

"Natural gas has been pummeled by bad-weather forecast after bad-weather forecast, so this is the first glimmer of hope in a while," Cooper said by phone Friday. "This could provide some enthusiasm for the market." ...

People who say it cannot be done should not interrupt those who are doing it.

A very interesting video where Paul Howarth, CEO of the National Nuclear Laboratory in the UK talks about the UK Government journey towards achieving 60% emissions reduction by 2050 and 80% by 2080.

Initially the Government’s (Labour) ideological position was this could be achieved with renewables until Government scientists developed an emissions reduction computer model.  When the model was run it showed that it is not possible to achieve the emissions reductions required until nuclear was included in the mix.

Based on science and not political ideology the UK Government with bipartisan agreement is now moving towards their emissions reduction goal by developing a nuclear energy industry that will also include a closed nuclear waste cycle by mid century.

Small Nuclear Reactors coming closer to fruition:

http://www.businesswire.com/news/home/20170313005622/en/GE-Hitachi-Nuclear-Energy-ARC-Nuclear-Announce

http://www.arcnuclear.com/

(interesting 20 year refuling cycle)

Small Size
Small enough that its modularized components can be shipped and installed at the site using regular commercial equipment, such as barges, rail, trucks, and construction cranes.
 
Sodium as Coolant
The use of sodium instead of water as the heat transfer agent in the reactor allows the reactor to operate at ambient pressure.  Its containment vessel is a double walled stainless steel tank rather than a 12 inch thick forged steel containment vessel required for traditional light water reactors.
 
Passive Safety
Effectively "walk away" fail safe and protection of the reactor from a melt down does not depend on extra pumps, operator intervention or any external system in the event a disaster destroys all electric power to the plant site.
 
Re-use of Nuclear Waste
The ability of ARC-100 to recycle traditional nuclear waste and generate energy, burn or transform plutonium that could be used for weapons and eliminate the need to bury or store large quantities of nuclear waste.
 
Twenty Year Refueling Cycle
The proprietary reactor core of the ARC reactor is designed to operate for 20+ years without refueling.

and so it goes

And a different take on small and modular reactors at the end of the article and in the middle an analysis of the standard large reactors
http://www.counterpunch.org/2017/03/14/terminal-decline-fukushima-and-the-deepening-crisis-of-nuclear-energy/

Small is beautiful?
The four Third Way / Breakthrough Institute authors argue that nuclear power must become substantially cheaper – thus ruling out large conventional reactors “operated at high atmospheric pressures, requiring enormous containment structures, multiply redundant back-up cooling systems, and water cooling towers and ponds, which account for much of the cost associated with building light-water reactors.”


following is a quote of a quote from Bull Atom Scient (the one that Sam Day used to edit decades ago)
“Without a clear-cut case for their advantages, it seems that small nuclear modular reactors are a solution looking for a problem. Of course in the world of digital innovation, this kind of upside-down relationship between solution and problem is pretty normal. Smart phones, Twitter, and high-definition television all began as solutions looking for problems.

Japan court rules government liable for Fukushima disaster
Terra Daily

A Japanese court on Friday ruled for the first time that the government bears [and shares]responsibility for the 2011 Fukushima nuclear disaster and ordered it and the plant operator to pay damages, officials and news reports said. ...


Plaintiffs received less than a quarter of what they sued for.
