Flooding at a Florida Nuclear Plant

, former director, Nuclear Safety Project

Role of Regulation in Nuclear Plant Safety #5

St. Lucie Unit 1 began operating in 1976. From the beginning, it was required by federal regulations to be protected against flooding from external hazards. After flooding in 2011 led to the meltdown of three reactors at Fukushima Dai-ichi in Japan, the NRC ordered owners to walk down their plants in 2012 to verify conformance with flood protection requirements and remedy all shortcomings. The owner of St. Lucie Unit 1 told the NRC that only one minor deficiency had been identified and it was fixed.

But heavy rainfall in January 2014 flooded the Unit 1 reactor auxiliary building with 50,000 gallons through flood barriers that had been missing since at least 1982. Unit 1 became as wet as the owner’s damp assurances and the NRC’s soggy oversight efforts. Read more >

Florida’s Nuclear Plants and Hurricane Irma

, Director of Nuclear Power Safety, Climate & Energy

Will Florida’s two nuclear plants, Turkey Point and St. Lucie, be able to withstand Hurricane Irma?

Florida governor Rick Scott, the utility Florida Power & Light (FP&L), and the US Nuclear Regulatory Commission (NRC) have all provided assurances that they will. But we are about to witness a giant experiment in the effectiveness of the NRC’s strategy for protecting nuclear plants from natural disasters. Read more >

Disaster by Design/ Safety by Intent #59

Safety by Intent

With ample warning, Hurricane Matthew made landfall in South Carolina coast on October 8, 2016, bringing along its heavy rainfall and high winds.

The Federal Emergency Management Agency conducted Disaster Initiated Reviews for nuclear plants in South Carolina, North Carolina and Florida to determine whether Hurricane Matthew adversely affected emergency planning measures within a 10-mile radius of each site. Read more >

Disaster by Design/Safety by Intent #3

Disaster by Design

The primary purpose of commercial nuclear power plants in the U.S. is to generate electricity. When not fulfilling that role, nuclear power plants that are shut down require electricity to run the equipment needed to prevent the irradiated fuel in the reactor core and spent fuel pool from damage by overheating. The March 2011 accident at Fukushima Daiichi in Japan graphically illustrated what can happen when nuclear plants do not get the electricity they require. Read more >

Assault on St. Lucie Nuclear Plant

, former director, Nuclear Safety Project

Fission Stories #167

Prior to 9/11, federal regulations required U.S. nuclear power plants to be defended against radiological sabotage carried out by a small group of outside attackers aided by one insider. After 9/11, the NRC revised the regulations to required defending against a slightly larger group of outside attackers aided by one insider. At least once every three years, the NRC monitors a simulated attack on each nuclear plant by mock intruders to judge how adequately the security measures are implemented. Read more >
