The inspectors identified an Unresolved It … The inspectors identified an Unresolved Item (URI) associated with troubleshooting activities on inoperable vacuum breakers. On May 14, 2009, and August 14, 2009, Entergy declared both the V1619- 5E and V16-19-5F torus-to-drywell vacuum breakers inoperable, respectively. The vacuum breakers were declared inoperable when it was identified that their breakaway force exceeded the maximum allowable TS value of 0.5 psid. Entergy entered TS 3.7.A.6.b, which stated that up to two out of ten torus-to-drywell vacuum breakers may be determined to be inoperable provided that they are secured, or known to be, in the closed position. On September 29,2009, and October 8,2009, Entergy conducted troubleshooting activities on both inoperable vacuum breakers. The troubleshooting activities involved opening and closing the inoperable vacuum breakers to obtain breakaway force data and to possibly repair the vacuum breakers. The inspectors noted TS 3.7.A.6 did not have a condition that allowed the opening of an inoperable vacuum breaker once it is secured in the closed position in accordance with the requirements of TS 3.7.A.6.b. Furthermore, TS 3.7.A.8 stated that if TS 3.7.A.6 cannot be met, an orderly shutdown shall be initiated immediately, and the reactor shall be in a cold shutdown within 24 hours. The inspectors noted that once the inoperable vacuum breakers are secured in the closed position, TS 3.7.A.6 can be met, and that opening the inoperable vacuum breakers is a potential violation of TS 3.7.A.6.b. Vacuum breakers can be opened for surveillance testing, however, there are no TS requirements to conduct surveillances on inoperable equipment. This issue remains unresolved pending a review by the NRC Office of Nuclear Reactor Regulation to determine if this issue constitutes a violation of Entergy Vermont Yankee TS.
