Unit 1 and Unit 2 technical specifications
LCO 3.7.10 required that if both trains of
CREVS become
inoperable than
LCO 3.0.3 shall be immediately entered. Additionally,
LCO 3.0.3 requires both units to be placed in Mode 3 within seven hours if the condition was not rectified. Contrary to the above, on August 10, with both trains of
CREVS rendered
inoperable, both units remained in Mode 1 for a period of approximately
24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The finding was entered into the licensees
CAP as CR 1201905. This finding was assessed using NRC
Inspection Manual Chapter (IMC) 0609, Attachment 4, and was determined to be of very low safety significance (Green) due to the finding only representing a degradation of the radiological barrier function provided for the control room.
