What is RETS-REMP ?

• Ken Sejkora
• Entergy Nuclear Northeast Pilgrim Station
• Presented at the 12th NUMUG Meeting
• Charlotte, NC / 25-27 Jun 2008

RETS-REMP

• Radioactive 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 Manual
• Radiological Environmental Monitoring Program, a
  subset of effluent control program used to detect
  impact of plant operations on the environment and
  members of the public.

Responsibilities of RETS-REMP

• Effluent Monitoring liquid and gaseous
• Nuclide and activity released
• Pathway dose assessment
• Meteorology plays role in dispersal and fate of
  airborne releases and resulting dose
• Environmental sampling/monitoring
• Monitor for radioactivity in the environment
  related to plant operations water, sediment,
  fish, shellfish, air, crops, milk and meat
  products, TLDs/direct radiation
• Meteorology plays role in dispersal and
  deposition of airborne radioactivity and
  concentrations in environmental media

4
Responsibilities of RETS-REMP

• Annual Reports to NRC
• Annual Radioactive Effluent Release Report
  present results of effluent releases and dose
  impact
• Annual Radiological Environmental Operating
  Report present results of REMP sampling efforts
• RETS-REMP personnel are often responsible for
  meteorological system at plants
• Often viewed as the end user for X/Q,D/Q
  dispersion factors related to dose assessment
• Often no formal training in meteorology

RETS-REMP Workshop

• The 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
  Committee
• The Steering Committee consists of eight to nine
  members, representing U.S. electric utilities

7
Annual Meetings

• First meeting was held in 1991, sponsored by
  Baltimore Gas Electric
• 2008 Meeting will be the 18th meeting
• Free and open exchange of information between
  utilities, regulators, and consultants regarding
  problems, solutions, and best practices

8
Accomplishments

• Work through Nuclear Energy Institute (NEI) to
  provide technical support on effluent and
  environmental monitoring issues, including review
  of pending NRC documents
• Supply 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 rulemaking
• Jason Jang Award
• Award in honor of Dr. Jason Jang, NRC inspector
  who fostered model RETS-REMP programs
• Presented 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 www.rets-remp.org
• RETS-REMP Discussion Group
• Yahoo discussion group, similar to NUMUG
  listserve
• http//tech.groups.yahoo.com/group/RETS_REMP/
• Send email to group administrator to join

Need for Meteorological Data

• X/Q,D/Q dispersion factors for dose assessment
• Long-term annual average factors for routine dose
  assessment, per NUREG-0133 and Regulatory Guide
  1.111
• Short-term factors for accident/emergency dose
  assessment
• Determine environmental monitoring locations
  based on prevailing winds
• Assist 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
