[ YNPS History
"* Achieved Initial Cnticality--1960
"* Began Commercial Operation-1 961
"* Upgrade to 600 MWt-1963
"* Decision to Cease Operations-2/1992
"* Possession Only Status --8/1992
"* Decommissioning Activities -1 992-present
"* Fuel Movement to ISFSI (Begin)-6/2002 IYNPS Decommissioning History
- Decommissioning Plan Submitted-12/1993
- Decommissioning Environmental Report 12/1993
- Characterization Activities Commence-1994
- Decommissioning Plan Approved 2/1995, Suspended 10/1995 and Re-Approved 10/1996
- LTP Submitted to NRC (Revision 1 - 12/97)
- Management Decision to Withdraw LTP (Availability of MARSSIM)-9/99
3 IYNPS Decommnissiomng History (Con't.)
"* Large Components Removed
"* Majority of SSCs Disposed of Off-Site
"* Significant Remediation and FSS Activities Performed Under Previously Submitted LTP
"* FSS Conducted Based Upon Guidance in a RG 1.86 o Draft NUREG/CR-5849 o Draft NUREG-1500 7
I Primary Auxiliary Building Scabblmg 4
I Safety Injection Room Floor Scabbling I Reactor Cavity Scabbling
5 i Near-Term Decommissioning Approach
- Demolish Buildings to Grade
- Demolish VC and Remove As Waste
- Structures To Remain "a
PAB Cubicle Corridor "a SFP/IX Pit
- Turbine, Waste Disposal, Service, and Warehouse Building Pads and Shoreline Structures
- Pedodic Re-Evaluation of Approach
6 I License Ternmnation Approach
"* Unrestricted Release (IOCFR20, Subpart E)
"* Survey to MARSSIM Guidance
"* Meet:
S25 mrem/yr (all pathways)
SALARA i LTP Project Goals
- Produce a License Termination Plan That.
3 Satisfies the requirements of 50 82(a)(9) u Considers available NRC guidance z Considers stakeholder interests (e g, Commonwealth of Massachusetts, EPA, local community) a Minimizes NRC requests for additional information LTP Development Approach
"* Ensure Consistency With NRC Guidance Documents (RG 1.179, NUREG-1700, NUREG-1727)
"* Use CY LTP As Model
"* Incorporate Site -Specific Data
"* Incorporate NRC Feedback
"* Maintain Open Communications
7
[LTP Development Considerations
"* Continued Safe Spent Fuel Storage
"* Ongoing Decommissioning Activities
"* Site-Specific Characteristics, e g.
u Geology o Hydrology u Meteorology I HSA/Site Characterization
"* Consistent With MARSSIM
"* Considers Prior Survey Data
"* HSA/Site Characterization Results Will o Provide basis for initial area classification z Identify additional samples/measurements needed z, Create tools to support remediation planning
"* HSA/Site Characterization Reports Will Be Submitted to NRC and Referenced in LTP I Initial Area Classification Activities
- Validate NUREG/CR-5849 Survey Data
- Validate Instrumentation Used
- Verify Ongoing Controls/Isolations
- Include Initial Classification in LTP
8 I Dose Modehng
"* Codes Selected.
RESRAD V6 21, BUILD V3 21
- Wide-spread use
- Probabilistic and determinstic modules
- Addresses complex hydrology and subsurface soil contamination
" Scenarios Considered
[ Resident farmer L Building occupancy
"* Probabilistic Mode for Sensitivity Analysis I Dose Modehng (Continued)
- Input Parameters Based Upon
-, Results of sensitivity analysis "z Site-specific information, e g,
"* Radionuclides of interest at YNPS
"* Site-specific geologic data
"* Site-specific meteorological data "o NUREG/CR-5512 Vol 3
" NUREG/CR-6697 I Final Status Survey
"* Based on MARSSIM
"* FSS Development Considerations Include u DQOs j Anticipated site conditions at time of FSS i Varying radionuclide mix z Site contamination distnbution z Monitoring instrumentation
