Contrary to this requirement, one secondary containment isolation valve was inoperable, but the licensee failed to take action to isolate the affected penetration within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, or be in Mode 3 within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Specifically, between August 13, 1994 and June 30, 2010, valve FDR-V-219 (a secondary containment isolation valve) was inoperable and not fully seated, but the licensee failed to take the actions prescribed in Technical Specification 3.6.4.2. This issue was entered into the licensees corrective action program as Condition Report 220785. The finding is of very low safety significance because it only represented a degradation of the radiological barrier function provided for the reactor building. |
