How High Did China’s May 2013 Launch Go?

On May 13, 2013, China launched a rocket on a suborbital trajectory to high altitude. China announced that the launch was part of a project to study space weather and that the probe carried out an experiment at high altitude. A report in China News (translation) stated that the launch reached an altitude of about 10,000 km. Read More

Nuclear Goldilocks: Combatting the Cumulative Effects of Non-Regulation

The U.S. nuclear power industry has been raising concerns about what is being called “the cumulative effects of regulation.” The industry sees NRC regulatory demands as an ever growing burden that it doesn’t believe adds significantly to public safety. Read More

Lochbaum Presentation to NRC Panel on Flooding

On January 6, the NRC is holding a hearing on the threat flooding and other extreme events pose to nuclear plants. Flooding at Fukushima, Ft. Calhoun and at a number of Northeast plants during Hurricane Sandy has prompted the NRC to take a closer look at plant flood protections. Read More

Continuing Concrete Problems at Seabrook

The concrete in buildings at the Seabrook nuclear plant is being attacked by a chemical reaction that causes the concrete to swell and crack. If the condition is severe enough, it can weaken the concrete enough to cause structural problems. This condition, called alkali silica reaction (ASR), has been discovered at 131 locations in multiple structures at Seabrook. Read More

Crowded Spent Fuel Pools

Spent fuel pools pose a much bigger threat to public safety than they should because of the large amount of radioactive material they contain, which could be released to the environment in a severe accident.

While concerns tend to focus on the nuclear fuel contained in reactor cores, cooling pools in the U.S. typically contain much more fuel than the core. Currently, U.S. pools overall contain over 5 times more radioactive fuel than is in all the reactor cores, and some individual reactor pools contain more than 8 times as much fuel as the reactor core. Yet the pools don’t have the same level of protection or safety systems as the reactor cores.  Read More

Radiation from Accelerating the Transfer of Spent Fuel from Pools to Casks

Contrary to claims by some in the nuclear industry, accelerating the transfer of spent fuel from cooling pools to dry casks would not pose a significant risk to workers from increased radiation exposure, and does not outweigh the benefits of such transfers. Read More

Lochbaum Testimony on Waste Bill and Dry Casks

Dave Lochbaum testified last week to the Senate Committee on Energy and Natural Resources Committee as part of a hearing on the Nuclear Waste Administration Act of 2013 (S. 1240). The bill is intended to create a process for dealing with spent nuclear fuel in the U.S., which has been piling up at nuclear reactor sites since the government has failed to open a geologic repository to store it.
