o ELECTRLCALPQWER SYSTEMS LIMITING CONDITION FOR OPERATION (Continued)
- For the purposes of completing maintenance, modification, and/or technical specification surveillarce requirements, on the 0 diesel generator and its support systems during a refuel outage, as part of pre-planned maintenance, modifications, and/or the surveillance program, the requirements of action statement b are modified to:
1.
Eliminate the requirement for performing technical specification surveillance requirements 4.8.1.1.1.a on each operable AC source, immediately and once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> thereafter, when the 0 diesel generator is declared inoperable.
