Columbia Generating Stations response below. From: [email protected] [mailto:[email protected]] On Behalf Of Barber, Jerry Sent: Wednesday, June 29, 2011 10:18 AM To: '[email protected]' Subject: Powernet: Are Anticipated Dose Rate Alarms Documented in CAP? Robinson would like to determine if other sites document "anticipated dose rate alarms" which occur after they have been discussed and documented during a pre-job brief, as "Adverse Conditions" using their site's Corrective Action Program (CAP). At Robinson our procedure requires us to perform a documented "Direct Reading Dosimeter" investigation for all dose and dose rate alarms, and to also document all dose and all unanticipated dose rate alarms in CAP. Does your site document anticipated dose rate alarms in CAP? No. We use the Health Physics electronic shift log to document anticipated alarms. All anticipated must be pre-briefed and documented in the RWP logbook prior to RCA entry. HP Supervision approval is required for all anticipated alarms. Does your site document unanticipated dose rate alarms in CAP? Yes. All unanticipated dose rate alarms as well as all dose alarms. Does your site use another tracking system (besides CAP) for tracking all dose and dose rate alarms? Yes. Health Physics Instruction (HPI) procedure requires and electronic dosimeter alarm investigation form to be completed for all alarms. These forms are retained in plant files and attached to the Condition Report. Jerry Barber Lead RC Specialist H.B. Robinson Nuclear Plant 843-857-1496 [email protected]
