NRC Spokesman Says No Danger to Public From San Onofre Shutdown

We're seeing plenty of activity around the news coming out of San Onfre Nuclear Generating Station, and I think the most important piece of information I've seen thus far has come from Victor Dricks, a spokesman for the NRC.

The following is excerpted from a story that appeared in the San Diego Union-Tribune:
Small traces of radioactive gas from a leak at the San Onofre nuclear plant may have reached the atmosphere, a spokesman for the Nuclear Regulatory Commission said Wednesday.

A reactor at the nuclear plant 45 miles north of San Diego was shut down on Tuesday when evidence emerged of a leak in a radioactive steam pipe in the plant's recently replaced generator.

Air extractors apparently carried small traces of radioactive gas from the generator area to an unsealed auxiliary building outside the reactor dome, setting off radiation alarms, said NRC spokesman Victor Dricks. The leak and possible escape of gas poses no danger, he said.

"If there was any radiation that escaped from the auxiliary building it would not pose any danger to the workers on site or to the public's health and safety," Dricks said. "It would have been a small fraction of the natural background radiation."
More later if events warrant.

Was the gas Tritium? I'm curious, since that's what happened at Byron, IL earlier this week, about 60 miles to my west. Does the Tritium really migrate through the metal tube walls?

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...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...
