It is estimated that it will be restored to operable in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Severe weather has been noted in the area. AOP-38, Acts of Nature, entry is not required.
Turnover: Shift orders are to alternate CCW Pumps to P-52A in service with P-52B and P-52C in standby and continue the power escalation to full power at 12%/hr. GOP-5 is in progress with GCL 5.1 completed up to Step 4.2.
