Progress Energy uses the following guidance for RWPs.
Low Risk Activities GENERAL RWP (LR) - No High Radiation Areas (HRAs) and no Locked High Radiation Areas (LHRAs) other than routine tasks for operations rounds, HP surveillances, inspections, and routine PM’s in these areas. - No Hot Particle Areas (HPAs)- - Activities that will not change radiological conditions in the plant (for example dose rates, contamination levels, air quality) - No aggressive work activities in contaminated areas that could change the radiological conditions. Moderate Risk Activities SPECIFIC RWP (MR) - Entry into HRAs and LHRAs for activities other than routine activities. - HPA entries- - Activities that can change radiological conditions in the area, but not to the extent that it would be considered a high risk activity. High Risk Activities SPECIFIC RWP (HR) - SOER 01-1 activities are those where: Work area exposure rates ≥ 1 R/hr, OR Activities that could create an increase in dose rate by ≥ 1 R/hr, OR Activities in which an individual could receive 500 mRem per entry, OR Activities designated by RP supervision or management - Radiography - Diving activities (in radiological significant areas) - VHRA entries -CV entries inside Bio-walls at power (PWR) [cid:[email protected]] Thanks, Bryant Akins Crystal River Nuclear Plant From: [email protected] [mailto:[email protected]] On Behalf Of Pell, Bryan Sent: Monday, May 23, 2011 4:19 PM To: '[email protected]' Subject: Powernet: Radiological Risk Constellation is benchmarking radiological risk. Does your site define radiological low, medium, or high risk? What criteria does your site use to establish low, medium and high radiological risk? For example, what makes a job radiological high risk? Thanks, Bryan Bryan S. Pell R.E.
