Finding

Title

LICENSEE-IDENTIFIED Violation

Description

Clinton TS Limiting Condition for Operation 3.4.11 requires that RCS pressure, temperature, heat up and cool down rates, and the recirculation loop temperature requirements shall be maintained within limits at all times. Contrary to the above, on October 28, 2013, during reactor startup from refueling outage C1R14, main control room operator logs showed a reactor coolant heat up rate of greater tha

100 degrees Fahrenheit per hour. The shift manager was notified of this trend when the coolant temperature had increased by about 111 degrees in one hour. At that time the shift manager made an incorrect interpretation of TSs that the LCO 3.4.11 heat up rate limit was based solely on the rate of change of the metal temperatures and not the actual RCS temperature. Technical Specifications 3.4.11 Figure 3.4.11-3 for RPV heat up/cool down limits states th

heat up/cool down of reactor coolant limit is less than 100 degrees/hour. The limit was exceeded without the Limiting Conditions for Operation actions being met in the time required. The licensee identified this violation during a

operations review of the CPS 9000.06D001 procedure log data and documented the issue in IR 01580123. Subsequently, on November 2, 2013, the licensee performed an evaluation of the RCS in accordance with TS 3.4.11 A.2 which determined that the RCS was acceptable for continued operation. The issue was more than minor because the performance deficiency, if left uncorrected, could be reasonably viewed as a precursor to a more significant event. The findin

screened as having very low safety significance (Green) because it only represented a degradation of the RCS barrier since further evaluation determined that the RCS was acceptable for continued operation.
