| Title | Maximum Licensed Power Level Exceeded |
| Event Description | During the course of operations, a potential error in the power calibration of the PUR-1, License Number R-87, was discovered. This calibration error would result in a special report requirement as specified in [(Technical Specification)] TS 6.7.b.1.c.vi, which is that an observed inadequacy in the implementation of a procedural control such that this inadequacy could have caused the development of an unsafe condition with regards to reactor operations. By extension the miscalibration caused a true reactor power higher than the measured reactor power. As such, this likely resulted in the operation in violation of the limiting condition for operation as established in TS Section 3 Table I and operation with an actual safety system setting for a required system less conservative than the limiting safety system settings specified in the Technical Specifications. These reporting requirements are Part i. and ii. of TS 6.7.b.1.c. The calibration error implicates a violation of the maximum licensed power level of 12 kW. The Safety Limit was not exceeded at any point. |
