NEI's Energy Markets Report - March 17-March 21, 2008

Here's a summary of what went on in the energy markets last week:

Electricity peak prices all decreased between $0.30-4.40/MWh. Though peak prices declined, prices at all hubs except ERCOT are still higher than their previous 52 week averages (see pages 1 and 3).

Estimated nuclear plant availability fell to 83 percent last week. Eleven reactors were down for refueling and nine were down for maintenance. Fort Calhoun’s turbine tripped while at 85% power due to a turbine control valve problem. Comanche Peak 2 tripped due to a broken sensing line. Wolf Creek 1 tripped due to a low steam generator level from the loss of a main feed water pump. Grand Gulf 1 scrammed due to an actuation of an RPS signal while the reactor was critical. Information is not yet available on why River Bend and Nine Mile Point 2 are down (NRC, see pages 2 and 4).

Gas prices at the Henry Hub fell $0.56 to $9.20/MMBtu. Gas prices are 34 percent higher than the same time last year. According to a recent CERA report, the higher natural gas prices over the past few months are due to colder than normal temperatures across much of the U.S., lower Canadian gas production, lower LNG imports, and higher storage withdrawals (see pages 1 and 3).

Spot coal prices from EIA have increased moderately to significantly at five basins - Central Appalachia, Northern Appalachia, Illinois, Uinta and Powder River. Spot prices at the Northern and Central Appalachia basins have increased from about $45/ton in November 2007 to $80/ton today. Prices at the Illinois and Uinta Basins have increased from about $35/ton and $25/ton, respectively, since December 2007 to over $50/ton and $40/ton today (http://www.eia.doe.gov/cneaf/coal/page/coalnews/coalmar.html). According to a Forbes article on 3/10, coal spot prices have been increasing due to tight supplies after producers in South Africa and Australia, which supply a large portion of Europe's and Asia's coal needs, were hit by severe weather and power problems.

Activists' Claims Distort Facts about Advanced Reactor Design

Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

What Happens During a Refueling Outage?

You may have noticed over the past few weeks that a number of nuclear plants are shut down for refueling outages or are resuming operations after just returning from one. This type of routine outage usually occurs in the spring or fall when electricity demand is low so that nuclear reactors can replace about one-third of the spent fuel rods with new fuel and conduct other routine maintenance and repairs at the plant. To get a better sense of how refueling works at a nuclear energy facility, I spoke with Marcus Nichol, NEI’s senior project manager for used fuel storage and transportation, and asked him to explain the basics. Why does a nuclear plant need to replace one-third of its fuel? Nichol: The main purpose of a refueling outage is to replace older fuel that is depleted—meaning it can no longer efficiently produce energy from nuclear fission reactions—with new fuel. This “used fuel” has typically been used in the reactor for four-and-a-half to six years before it is pe...

How Much Land Does Nuclear, Wind and Solar Really Need?

Not too long ago, we reviewed a report that looked at nuclear energy (and other energy sources) as biodiversity agents. This had to do, in part, with the amount of land a facility needs to function. Nuclear energy and fossil fuel plants use relatively little, wind farms and solar arrays quite a lot of land . Based on an objective and transparent analysis of our sustainable energy choices, we have come to the evidence-based conclusion that nuclear energy is a good option for biodiversity conservation (and society in general) and that other alternatives to fossil fuels should be subjected to the same cost–benefit analyses (in terms of biodiversity and climate outcomes, as well as sociopolitical imperatives) before accepting or dismissing them. Writer Barry Brook, who collected 75 scientists to endorse his paper, is interested in land use as it impacts flora and fauna. Biodiversity concerns do not get as much play as they might – and, when they do, it annoys many when land is withdraw...
