1 Sejkora: What is RETS-REMP? Ken SejkoraEntergy Nuclear Northeast – Pilgrim StationPresented at the 12th NUMUG MeetingCharlotte, NC / Jun 200812th NUMUG Meeting / Charlotte, NC / Jun 2008
2 RETS-REMPRadioactive Effluent Technical Specifications, terminology held over from when effluent controls were part of plant Technical Specifications… most plants have relocated effluent controls to the Offsite Dose Calculation ManualRadiological Environmental Monitoring Program, a subset of effluent control program used to detect impact of plant operations on the environment and members of the public.
3 Responsibilities of RETS-REMP Effluent Monitoring – liquid and gaseousNuclide and activity releasedPathway dose assessmentMeteorology plays role in dispersal and fate of airborne releases and resulting doseEnvironmental sampling/monitoringMonitor for radioactivity in the environment related to plant operations… water, sediment, fish, shellfish, air, crops, milk and meat products, TLDs/direct radiationMeteorology plays role in dispersal and deposition of airborne radioactivity and concentrations in environmental media
4 Responsibilities of RETS-REMP Annual Reports to NRCAnnual Radioactive Effluent Release Report – present results of effluent releases and dose impactAnnual Radiological Environmental Operating Report – present results of REMP sampling effortsRETS-REMP personnel are often responsible for meteorological system at plantsOften viewed as the “end user” for X/Q,D/Q dispersion factors related to dose assessmentOften no formal training in meteorology
5 RETS-REMP WorkshopThe RETS-REMP Workshop is a forum to exchange practical experiences and issues related to the Radioactive Effluent Technical Specifications and Radiological Environmental Monitoring Programs at commercial nuclear power plants.The workshop focuses on monitoring radioactivity in effluent releases from nuclear power plants, and on assessing the environmental consequences of such releases.
6 RETS-REMP Organization RETS-REMP Workshop is managed by the Steering CommitteeThe Steering Committee consists of eight to nine members, representing U.S. electric utilities
7 Annual MeetingsFirst meeting was held in 1991, sponsored by Baltimore Gas & Electric2008 Meeting will be the 18th meetingFree and open exchange of information between utilities, regulators, and consultants regarding problems, solutions, and best practices
8 AccomplishmentsWork through Nuclear Energy Institute (NEI) to provide technical support on effluent and environmental monitoring issues, including review of pending NRC documentsSupply technical expertise to Electric Power Research Institute (EPRI) on effluent and environmental issues
9 Accomplishments - continued In past, attempted to develop Position Papers acceptable to NRC – problems with perception of involvement with rulemakingJason Jang AwardAward in honor of Dr. Jason Jang, NRC inspector who fostered model RETS-REMP programsPresented annually to individual who has made significant contributions to the field of RETS-REMP or has administered exemplary programs
10 Accomplishments - continued Website – coordinated through North American Technical Center (as is NUMUG website)URL:RETS-REMP Discussion GroupYahoo discussion group, similar to NUMUG listserveSend to group administrator to join
11 Need for Meteorological Data X/Q,D/Q dispersion factors for dose assessmentLong-term annual average factors for routine dose assessment, per NUREG-0133 and Regulatory Guide 1.111Short-term factors for accident/emergency dose assessmentDetermine environmental monitoring locations based on prevailing windsAssist in understanding fallout and washout phenomena
12 Need for Meteorological Data - continued Although RETS-REMP personnel are often responsible for meteorological programs, and rely on met data as “end users”, we often lack meteorological training, and have to rely on expertise of NUMUG members to help us through the “rough spots”
