NRC publishes proposed post-Fukushima action schedule

Staff of the US Nuclear Regulatory Commission have published a proposed schedule to implement the 12 post-Fukushima recommendations that it issued in July 2011 for US nuclear power plants.

This is coincidental with the NRC program on seismic issues related to NPPs.

Nuclear power plants are built to withstand environmental hazards, including earthquakes. Even those plants that are located outside of areas with extensive seismic activity are designed for safety in the event of such a natural disaster. The Nuclear Regulatory Commission (NRC) requires all of its licensees to take seismic activity into account when designing and maintaining its nuclear power plants. When new seismic hazard information becomes available, the NRC evaluates the new data and models and determines if any changes are needed at plants. The newest seismic data suggests that although the potential seismic hazard at some nuclear power plants in central and eastern states may have increased beyond previous estimates, all operating nuclear plants remain safe with no need for immediate action.

With regard to design basis scenarios and spent fuel pool cooling/instrumentation, is the NRC looking at permanent installation or leaning more towards portable equipment? During the Fukushima accident, Westinghouse created a portable spent fuel pool cooling system. I don't know any technical details of it, however I was able to find this article.

Related to Are US Nuclear Power Plants Prepared for Earthquakes?

1. What is the US NRC's role in post-Fukushima actions?

The US Nuclear Regulatory Commission (NRC) is responsible for regulating the safety and security of commercial nuclear power plants in the United States. This includes overseeing the implementation of safety measures and regulations in response to the 2011 Fukushima nuclear disaster in Japan.

2. What specific actions has the US NRC taken since the Fukushima disaster?

In response to the Fukushima disaster, the US NRC has implemented a number of actions to enhance the safety and security of nuclear power plants in the United States. These actions include ordering nuclear power plants to conduct seismic and flooding risk assessments, requiring the installation of additional backup power sources, and improving emergency preparedness and response plans.

3. How has the US NRC addressed the issue of spent fuel storage after Fukushima?

The US NRC has issued new regulations and requirements for the storage of spent nuclear fuel after the Fukushima disaster. These include increased oversight of spent fuel pools, requiring plants to have additional backup cooling systems for spent fuel, and implementing stricter guidelines for the transfer of spent fuel to dry cask storage.

4. What is the status of the US NRC's post-Fukushima actions?

The US NRC has completed the majority of its post-Fukushima actions, including issuing new regulations and requirements, conducting safety inspections and assessments, and working with nuclear power plants to implement necessary changes. However, the NRC continues to monitor the situation and may make additional changes or updates as needed.

5. How has the US NRC collaborated with other countries in response to Fukushima?

The US NRC has coordinated with other countries and international organizations to share information and lessons learned from the Fukushima disaster. This collaboration has helped to identify and address potential safety issues at nuclear power plants around the world, and has led to the implementation of new safety measures and regulations globally.
