All,
Exelon is conducting an informal benchmark of OE 36193 - Reactor Power Change During Reactor Containment Building Bioshield Entry (Harris). The OE lists the following lessons learned and corrective actions: * Work activity risk management processes must include both online and outage work activities in plant reactor modes 1 and 2. * All Radiation Protection procedures that are implemented with the plant condition of reactor at "power" will be implemented when the reactor is "critical". * Prior to any entry into the bio-shield the Radiation Protection Manager shall ensure there is alignment with Operations, Duty Manager, and Radiation Protection that reactor power is planned to be constant while personnel are inside the bio-shield and the reactor power level is consistent with the conditions briefed. * For emergent and planned entries into the bioshield wall the Duty Manager, Radiation Protection Manager, and Nuclear Shift Manager must be briefed on the ALARA projections and the basis for the estimate (that is, reactor power level). * IAW PLP-511, Radiation Control * Protection Program, all entries inside the bio-shield wall, with the reactor critical will be planned and executed as High Radiological Risk Significant Activity (RRSA). Exelon would like to know: For BWRs, do you have any additional guidance in steam dependent areas that would prevent another event similar to this OE? Please direct your responses to Edward Conjar at [email protected].
