g e INSERT A Proposed Rewrite of Technical Specification 3.8.1.1 Action Statements a. With one offsite circuit inoperable, demonstrate the OPERABILITY of the remaining A.C. sources by performing Surveillance Requirement 4.8.1.1.1 within I hour and at least once per 8 hours thereafter. If either diesel generator has not been successfully tested within the past 24 hours, demonstrate its OPERABILITY by performing Surveillance Requirement 4.8.1.1.2.a.2 separately for each such diesel generator within 24 hours. Restore the offsite circuit to OPERABLE status within 72 hours or be in COLD SHUTDOWN within the following 36 hours. b. With one diesel generator inoperable, demonstrate the OPERABILITY of the A.C. offsite sources by performing Surveillance Requirement 4.8.1.1.1 within I hour and at least once per 8 hours thereafter; and if the diesel generator became inoperable due to any cause other than preplanned preventative maintenance or ' testing, demonstrate the OPERABILITY of the remaining OPERABLE diesel generator by performing Surveillance Requirement 4.8.1.1.2.a.2 within 24 hours *; restore the diesel generator to OPERABLE status within 72 hours or be in COLD SHUTDOWN within the fellowing 36 hours. c. With one offsite circuit and one diesel generator inoperable, demonstrate the OPERABILITY of the remaining A.C. sources by performing Surveillance Requirement 4.8.1.1.1 within I hour and at least once per 8 hours thereafter; and if the diesel generator became inoperable due to any cause other than preplanned preventative maintenance or testing, demonstrate the OPERABILITY of the remaining OPERABLE diesel generator by performing Surveillance Requirement 4.8.1.1.2.a.2 within 8 hours *; restore one of the inoperable sources to OPERABLE status within 12 hours or be in COLD SHUTDOWN within the following 36 hours. Restore the other A.C. power source (offsite circuit or diesel generator) to OPERABLE status in accordance with the provisions of Section 3.8.1.1 Action Statement a or b, as appropriate with the time requirement of that Action Statement based on the time of initial loss of the remaining inoperable A.C. power source. A successful tesi. of diesel generator OPERABILITY per Surveillance Requirement 4.8.1.1.2.a.2 performed under this Action Statement for an OPERABLE diesel generator or a restored to OPERABLE diesel generator-satisfies the diesel generator test requirement of Action Statement a or b. d. With two of the required offsite A.C. circuits inoperable, demonstrate the OPERABILITY of two diesel generators by sequentially performing Surveillance Requirement 4.8.1.1.2.a.2 on both diesel generators within 8 hours, unless the diesel generators are already_ operating; restore one of the inoperable offsite sources to OPERABLE status with 24 hours or be in at least HOT SHUTDOWN within the next 4 hours. Fo11cwing restoration of one offsite source, follow Action Statement a with the time requirement of that Action Statement based on the time of initial loss of the remaining inoperable offsite A.C. circuit. A successful test (s) of diesel generator OPERABILITY per Surveillance Requirement 4.8.1.1.2.a.2 performed under this Action Statement for the OPERABLE diesel generators satisfies the diesel generator test requirement of Action Statement a.
- This test is required to be completed regardless of when the inoperable diesel generator is restored to OPERABLE.
With two of the above required diesel generators inoperable, demonstrate e. the OPERABILITY of two offsite A.C. circuits by performing Surveillance Requirement 4.8.1.1.1 within I hour and at least once per 8 hours thereafter; restore one of the inoperable diesel generators to OPERABLE. status within 2 hours or be in COLD SHUTDOWN within the following 36 hours. -Following restoration of one diesel generator unit, follow Action Statement b with the time requirement of that Action Statement based on the time of initial loss of the remaining inoperable diesel generator. A successful. test of dierel generator OPERABILITY per Surveillance Requirement 4.8.1.1.2.a.2 performed under this Action Statement for a restored to OPERABLE diesel generator satisfies.the diesel generator test requirement of Action Statement b.
