On April 16, 2012, the petitioner requested that the NRC take action with regard to Indian Point Nuclear Generating Unit No. 2. The petitioner requests that the NRC order the licensee of Indian Point Nuclear Generating Unit No. 2 to remove the passive autocatalytic recombiners (PARs) because the PAR system could have unintended ignitions in the event of a severe accident, which, in turn, could cause a hydrogen detonation. As the basis for this request, the petitioner references experimental data where PARs malfunction in environments containing high concentrations of combustible gases by having ignitions. The petitioner asserts that the PARs could be overwhelmed by the production of hydrogen following a severe reactor accident and a resulting ignition could lead to a detonation that challenges the structural integrity of the containment structure.
The request is being treated pursuant to Title 10 of the
For the Nuclear Regulatory Commission.
