It is probably easier for you to reply via email, but I would enjoy talking with you.
When we drain the cavity following refueling we typically find contamination levels exceeding 1,000,000 dpm/100 cm2 and multiple spots >1 rem/hour on contact. We, therefore, prescribe plastic suits and PAPHs for an HP and SRO to enter the cavity during reactor head set. I was challenged to determine why other plants experience contamination levels < 200,000 dpm/100 cm2 and are able to allow entry into the cavity without respiratory protection during reactor head set. 1. What are your typical radiological conditions in the cavity during reactor head set at your station (e.g., contamination levels) 2. What are your station's requirements for respiratory protection and protective clothing for workers in the cavity during reactor head set? 3. Also, is there feasibly anything that can be done to improve Surry's radiological conditions in the cavity during reactor head set? We do not have polished cavity surfaces and do not perform ultrasonic cleaning of spent fuel. A quick response would be greatly appreciated.
