Finding

Title

Licensee-Identified Violation

Description

The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section VI of the NRC Enforcement Policy, for being dispositioned as a noncited violation. License Condition 2.C(26) and 2.C(27), Mitigation Strategy License Condition, for Units 2 and 3 respectively, requires the licensee to develop and maintain strategies for addressing large fires and explosions. One strategy relied on a skid mounted pump with a non-collapsible hose to provide makeup for the reactor water storage tank. Contrary to the above, on June 9, 2010, the licensee identified during a flow/pressure test that the strategy was unavailable because the hose was not rated for the system pressure and uncoupled during the test. The finding is greater than minor because a strategy was unavailable and unrecoverable, as defined by Inspection Manual Chapter 0609, Appendix L, B.5.b Significance Determination Process. The finding is Green because the failure to assess the adequacy of fire fighting assets would have caused an unrecoverable unavailability of only one mitigating strategy. The issue was entered into the licensees corrective action program as Nuclear Notifications (NN) 200960081 and 200959384.
