Morning Update

From NEI’s Japan launch page

At a March 19 news conference, Japan’s Chief Cabinet Secretary Yukio Edano said that sea water injection is continuing at reactors 1, 2 and 3 at the Fukushima Daiichi nuclear power plant.

Preparations were being made to spray water into the used fuel pool at reactor 4, and an unmanned vehicle sprayed more than 1,500 gallons of water over seven hours into the used fuel pool at reactor 3, Edano said. He also said he believed that the situation at the reactor 3 fuel pool is stabilizing.

Some reactor cooling capacity has been restored at reactors 5 and 6 after the installation of generators at those reactors, Edano added.
Edano said that progress had been made on “a fundamental solution” to restore power at the Fukushima Daiichi nuclear power plant, with electricity expected to be restored at reactors 1 and 2 today and reactor 3 as early as Sunday.

Edano said that additional equipment was being transported to the site and that other means of providing cooling water to the pool is be examined.

Radiation dose at the west gate of the Fukushima Daiichi was 83 millirem per hour on March 18 at 7:10 p.m. EDT and dropped to 36 millirem per hour by 8 p.m., Edano said. Radiation levels have decreased since March 16. Although they are higher than normal, radiation levels near the reactors are within the range that allows workers to continue onsite recovery measures, the International Atomic Energy Agency said.

According to the IAEA, radiation dose rates in Tokyo and other areas outside the 30-kilometer zone remain far below levels which would require any protective action by the public.

Radiation levels have increased above the federal government’s level in some food products from the Fukushima Prefecture and nearby areas. These levels were detected in samples of milk in Fukushima Prefecture and 6 samples of spinach in neighboring Ibaraki Prefecture, according to the Japan Atomic Industrial Forum. Edano said that if these products are consumed for a year, the total radiation dose would be equivalent to 1 CT scan.

Additional monitoring of food products is continuing in those regions.

Knowing What You’ve Got Before It’s Gone in Nuclear Energy

The following is a guest post from Matt Wald, senior director of policy analysis and strategic planning at NEI. Follow Matt on Twitter at @MattLWald.

Nuclear energy is by far the largest source of carbon prevention in the United States, but this is a rough time to be in the business of selling electricity due to cheap natural gas and a flood of subsidized renewable energy. Some nuclear plants have closed prematurely, and others likely will follow.
In recent weeks, Exelon and the Omaha Public Power District said that they might close the Clinton, Quad Cities and Fort Calhoun nuclear reactors. As Joni Mitchell’s famous song says, “Don’t it always seem to go that you don’t what you’ve got ‘til it’s gone.”
More than 100 energy and policy experts will gather in a U.S. Senate meeting room on May 19 to talk about how to improve the viability of existing nuclear plants. The event will be webcast, and a link will be available here.
Unlike other energy sources, nuclear power plants get no specia…

Making Clouds for a Living

Donell Banks works at Southern Nuclear’s Plant Vogtle units 3 and 4 as a shift supervisor in Operations, but is in the process of transitioning to his newly appointed role as the daily work controls manager. He has been in the nuclear energy industry for about 11 years.

I love what I do because I have the unique opportunity to help shape the direction and influence the culture for the future of nuclear power in the United States. Every single day presents a new challenge, but I wouldn't have it any other way. As a shift supervisor, I was primarily responsible for managing the development of procedures and programs to support operation of the first new nuclear units in the United States in more than 30 years. As the daily work controls manager, I will be responsible for oversight of the execution and scheduling of daily work to ensure organizational readiness to operate the new units.

I envision a nuclear energy industry that leverages the technology of today to improve efficiency…

Nuclear: Energy for All Political Seasons

The electoral college will soon confirm a surprise election result, Donald Trump. However, in the electricity world, there are fewer surprises – physics and economics will continue to apply, and Republicans and Democrats are going to find a lot to like about nuclear energy over the next four years.

In a Trump administration, the carbon conversation is going to be less prominent. But the nuclear value proposition is still there. We bring steady jobs to rural areas, including in the Rust Belt, which put Donald Trump in office. Nuclear plants keep the surrounding communities vibrant.

We hold down electricity costs for the whole economy. We provide energy diversity, reducing the risk of disruption. We are a critical part of America’s industrial infrastructure, and the importance of infrastructure is something that President-Elect Trump has stressed.

One of our infrastructure challenges is natural gas pipelines, which have gotten more congested as extremely low gas prices have pulled m…
