10 CFR 50.73(a)(2)(i)(B) requires that conditions prohibited by TSs be reported to the NRC via a LER within 60 days of the discovery of the event. Contrary to this requirement, the licensee did not report the failure of multiple
MSRVs to pass their pressure lift tests, a condition prohibited by TSs, to the NRC via a LER within 60days of the discovery of the event. The
MSRVs failed the lift tests in October 2006on Unit 1, April 2007 on Unit 2, and October 2007 on Unit 3. The licensee identified the missed reports while investigating the failure of multiple Unit 2
MSRVs to pass their lift pressure test on October 24, 2009. The inspectors determined this licensee identified finding was a
Severity Level IV NCV in accordance with the
NRC Enforcement Policy, section IV.A.3., due to the failure to make required LERs following the failed tests, because the licensee knew of the information to be reported, but did not recognize that a report was required to be made. These prior events were also described in
LER 05000270/2008002-00. The event is captured in the licensees corrective action program as
PIP O-08-06525
