The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

“Uprating” – a cheap way to increase power from nuclear reactors, but is it safe?

nuclear watchdogs have warned that these bigger uprates also carry bigger risks.

“This trend is, in principle, detrimental to the stability characteristics of the reactor, inasmuch as it increases the probability of instability events and increases the severity of such events, if they were to occur,” the Advisory Committee on Reactor Safeguards, which is mandated by Congress to advise the NRC, has warned 

How to expand nuclear power without attracting (too much) attention
Washington Times,  by Brad Plumer   July 18, 2012 Since the 1970s, construction on new nuclear reactors in the United States has largely ground to a halt, thanks to public protests, regulatory obstacles and tight financing. Yet over that same period, U.S. utilities have managed to increase the amount of electricity they get from nuclear power. By quite a lot, in fact.
How is that possible? Through a process known as “uprating.” According to a new analysis by the U.S. Energy Information Administration, the operators of 98 of the country’s 104 commercial nuclear reactors have asked regulators for permission to boost capacity from their existing plants. All in all, the Nuclear Regulatory Commission has approved more than 6,500 megawatts worth of uprates since 1977. That’s the equivalent of building six entirely new nuclear reactors—and during a period when fresh plants were impossible to build.

There are several ways to boost the capacity of a nuclear power plant. Continue reading →

Under the public radar, nuclear power is “uprated”, bringing safety concerns

nuclear watchdogs and the U.S. Nuclear Regulatory Commission’s own safety advisory panel have expressed concern over larger boosts — some by up to 20% — that the NRC began approving in 1998. Twenty of the nation’s 104 reactors have undergone these “extended power uprates.”

U.S. is increasing nuclear power through uprating Turning up the power is a little-publicized way of getting more electricity from existing nuclear plants. But scrutiny is likely to increase in the wake of Japan’s nuclear crisis. LA Times, April 17, 2011|By Alan Zarembo and Ben Welsh, Los Angeles Times

The U.S. nuclear industry is turning up the power on old reactors, spurring quiet debate over the safety of pushing aging equipment beyond its original specifications.

The little-publicized practice, known as uprating, has expanded the country’s nuclear capacity without the financial risks, public anxiety and political obstacles that have halted the construction of new plants for the last 15 years.
The power boosts come from more potent fuel rods in the reactor core and, sometimes, more highly enriched uranium. As a result, the nuclear reactions generate more heat, which boils more water into steam to drive the turbines that make electricity. Continue reading →

It’s already happening – solar hot water, and solar energy cooling systems

According to the International Energy Agency, solar heating and cooling (SHC) could make a dramatic impact on the world’s electricity grids, providing 17 per cent of all energy required for heating in buildings, industrial processes, swimming pools, and 17 per cent of cooling needs. 

Solar cooling technologies are relatively new, and not widely deployed – only 711 systems were deployed in the world in 2011, according to the IEA …..The IEA suggests that solar cooling particularly useful in handling electricity peaks, because it produces at the time of  highest demand.  It says the technology is already competitive in tropical regions with high electricity costs, including a 1.47MW capacity installation installed at a college in Singapore, was reportedly fully cost competitive without subsidies.

Solar Insights: Is solar hot water (and cooling) the next big thing? REneweconomy, By Giles Parkinson  19 July 2012 Amid the dramatic cost reductions and soaring demand for solar PV (photovoltaic) technologies in Australia and across the world, the long established idea of using the sun to heat water has taken a back seat.  In Australia, where SHW once dominated the local rooftop industry, installations were outpointed by rooftop PV by a factor of 5 in the last year.

But now SHW it is tipped to make a return to centre stage, along with relatively new solar thermal technologies that use the sun to provide heating and cooling for office and building spaces, district heating and under-floor heating in cooler climates, as well as for industrial processes and in hybrid systems with solar PV (known at PV-T). At a larger scale, it could one day be used for water treatment and desalination. Continue reading →

Amid USA heatwave, loss of power to cooling equipment brings shutdown to Pennsylvania nuclear reactor

Exelon shuts Pa. Limerick 1 nuclear power reactor, Reuters Jul 19, 2012   By Scott DiSavino July 18 – Exelon Corp shut down the 1,130-megawatt (MW) Unit 1 at the Limerick nuclear power plant in Pennsylvania early Wednesday following an electrical disturbance on the non-nuclear side of the plant, the company said in a release.

The outage came at a bad time for the power grid: Homes and businesses in the U.S. Mid-Atlantic are cranking up their air conditioners amid a brutal heat wave blanketing the region.
The electrical disturbance caused a loss of power to generator cooling equipment, the company said. The unit will remain offline until repairs, inspections and testing are
completed, it said…. http://in.reuters.com/article/2012/07/18/utilities-operations-exelon-limerick-idINL2E8II8A620120718

For relicensing nuclear plants, Nuclear Regulatory Commission does not consider costs of spent fuel disposal

Paradoxically, while the NRC allows potential earnings from a re-licensed plant to be considered as a way to cover the costs of plant shut-down, it does not consider the potential for those added years of operation to generate additional spent fuel when calculating the cost of shutting the plant down.

Group seeks to have spent fuel a factor in re-licensing Limerick plant The Mercury By Evan Brandt  07/17/12  LIMERICK — Despite a recent federal court ruling invalidating a rule that would allow storage of radioactive spent nuclear fuel rods at nuclear power plants for 60 years after they’ve closed, the Nuclear Regulatory Commission has no plans to consider the issue when deciding on whether to re-license Exelon Nuclear’s Limerick Generating Station    for an additional 20 years.

The   National Resources Defense Council    disagrees with that position and filed papers July 9 seeking to amend   its challenge to Exelon’s re-licensing  application Continue reading →
