TEPCO Initiates Gas Sampling for Reactors 1, 2

Plant Status

• Workers at Tokyo Electric Power Co.’s (TEPCO) Fukushima Daiichi nuclear energy facility in Japan will begin sampling gases inside containment at reactors 1 and 2 to obtain more accurate data on the types and amount of radioactive substances being released. TEPCO hopes that analysis of the samples will help determine the extent to which nuclear fuel from the reactors is leaking into containment. The gases will be extracted through pipes and analyzed on the first floor of the reactor buildings. Radiation measurements thus far have been based on readings taken on the facility premises. Sampling is scheduled to begin today at reactor 1 and in early August at reactor 2. TEPCO has not yet made plans for sampling at reactor 3, where radiation levels remain high. This is because TEPCO only began injecting nitrogen into reactor 3 on July 15 to minimize the risk of a hydrogen explosion. Nitrogen injection into reactors 1 and 2 began in April and June.

• TEPCO plans to issue an updated roadmap to recovery at the Fukushima Daiichi facility in mid-August. Industry/Regulatory/Political Issues

Industry/Regulatory/Political Issues

• The U.S. Nuclear Regulatory Commission held a public meeting with stakeholders July 28 to discuss the agency’s near-term task force recommendations for safety enhancements at U.S. nuclear energy facilities after the Fukushima accident. Numerous stakeholders, including the industry, called for a thorough and methodical review of accident details as they become available so that regulatory actions are consistent with lessons learned. In the next several weeks, the five-member commission is expected to provide direction to the NRC staff on next steps.

• Japanese Chief Cabinet Secretary Yukio Edano has ordered the governor of Miyagi Prefecture to suspend all shipments of beef cattle after levels of cesium above the government safety limit were detected in some cattle raised there. Miyagi is the second prefecture to have cattle shipments banned. Fukushima Prefecture received a suspension order last week.

Upcoming Events

• The U.S. Senate Committee on Environment and Public Works will hold a hearing Aug. 2 to review the NRC’s near-term task force recommendations for enhancing reactor safety. The witness list has not been announced.

Here's a fun one : News item in the Brattleboro Reformer week of Sept. 1rst 1979 : 200, 000 gallons of radioactive water into the Connecticut river from Vermont Yankee nuclear plant.
Official comment from the plant : - "amounts are so little they won't be detected in the fish "
More than 30 years later news item in the Rutland Herald July 6 2010 :

Strontium 90 detected again in fish in the Connecticut river.

Official comment from the plant:
- Strontium 90 is from nuclear testing in the 1960's and Chernobyl...
Liar! Liar! Pants on fire !!!
Actual radioactive effluent reports
to the NRC ? Strontium 90 produced at the plant from 2002 to 2005.
Half life ? 28.7 years !!!
Vermont Yankee officials had to back step and say they found some
Strontium 90 between two buildings.

The really funny thing, Anonymous, is that you are the one engaged in deception.

Where were those fish found, in 2010?
Upstream of the plant. By no small distance. Nothing to do with any releases from the plant, and emphatically due to weapons background.

On to the leak which produced the tiny quantities of tritium that allowed Shumlin to upset Vermonters... How far had the miniscule amounts of strontium-90 travelled from the pipe tunnel? A few feet.

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

Why America Needs the MOX Facility

If Isaiah had been a nuclear engineer, he’d have loved this project. And the Trump Administration should too, despite the proposal to eliminate it in the FY 2018 budget.

The project is a massive factory near Aiken, S.C., that will take plutonium from the government’s arsenal and turn it into fuel for civilian power reactors. The plutonium, made by the United States during the Cold War in a competition with the Soviet Union, is now surplus, and the United States and the Russian Federation jointly agreed to reduce their stocks, to reduce the chance of its use in weapons. Over two thousand construction workers, technicians and engineers are at work to enable the transformation.

Carrying Isaiah’s “swords into plowshares” vision into the nuclear field did not originate with plutonium. In 1993, the United States and Russia began a 20-year program to take weapons-grade uranium out of the Russian inventory, dilute it to levels appropriate for civilian power plants, and then use it to produce…

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.

Huh?

The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.


What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…
