Halter, Mandy Monday, June 20, 2011 1:33 PM'pbode@entergy.com' Part 21 -KASI MOV and AOV Software EN46955.pdf; KVAP-Software-for-AOV-&-MOV-design-basis-margin-calculations-for-JOG-Progra m-lmplementation-G L-96-05-Periodic-Verification-margin-improvement.pdf Paul, Attached is the Part 21 that came out of Oconee.(attached above EN 46955). The defect is related to errors in the Kalsi Engineering Valve and Actuator Program (KVAP) software that provide default flow and torque coefficients for ball and plug valves which can affect margin predictions.
Please confirm whether or not Indian Point has reviewed this issue for applicability.

Communication between Kalsi and Duke Energy personnel confirmed that non-conservative torque values were calculated for select ball valves used at Oconee for containment isolation.
As a result of the Kalsi error, the non-conservatively calculated torque values resulted in negative actuator margins, calling into question the actuators' capability to close the valves under all design conditions.
Therefore, it has been determined that the KVAP software program error constitutes a defect, reportable under I OCFR21.Initial Safety Significance:
Four safety-related contairnent isolation valves in the High Pressure Injection system were impacted, requiring entry into TS 3.6.3, Containment Isolation Valves, on two Oconee units.Corrective Action(s):
- 1. Upon further calculation, two of the containment isolation valves were determined to have adequate margin and were declared operable.2. Two other containment isolation valves required modifications to restore operability.
