OVERVIEW OF NRC'S LICENSE TERMINATIONRULETERMINATION RULEPresentation at the West Valley Quarterly Public Meeting May 28, 2014 Robert L. Johnson 1
REGULATIONS AND GUIDANCE*Re g ulations: 10 CFR 20 Sub p art E (License Termination gp(Rule (LTR))*Statements of Consideration (SOC) for LTR*Guidance: Consolidated Decommissioning Guidance, NUREG-1757, Vol. 1, 2, and 3

- Recognition that there may be cases where achieving unrestrictedreleasewouldnotbereasonable(egwherecost unrestricted release would not be reasonable (e.g., where cost would be excessive) *Flexibility

-Screen out sites that should be removing contamination to achieve unrestricted release*A site would be eligible if "- further reductions in residualradioactivitynecessarytocomplywiththe residual radioactivity necessary to comply with the provisions of 20.1402 -would result in net public or environmental harm or
-were not being made because the residual levels associated with restricted conditions are ALARA."
5 RESTRICTED RELEASE ELIGIBILITY(CONT)
ELIGIBILITY (CONT.)*Commissions' Orders regarding Shieldalloy
-Series of Shieldalloylawsuits with associated Court and Commission actions-Explain original meaning of provision and clarifies the analysis is limitedtofurtherremovalofresidualradioactivity limited to further removal of residual radioactivity-Not a comparison of individual doses of restricted and unrestricted release and selection of the lowest dose-Cost benefit analyses following NUREG-1757, Appendix N *Costs/benefits of further removal of residual radioactive material from levels proposed to remain onsite to the unrestricted release level *Net public harm analysis (costs of harm to people and environment compared to benefits, e.g., collective dose averted dollar value)ALARA(totalcostscomparedtobenefitsegcollectiedoseaerted
- ALARA (total costs compared to benefits , e.g., collecti v e dose a v erted dollar value) 6 RESTRICTED RELEASE INSTITUTIONALCONTROLS(ICs)
INSTITUTIONAL CONTROLS (ICs)*10 CFR 20.1403 (b) ()*Guidance in NUREG-1757, Vol. 1, Rev. 2 *Legally enforceable ICs to restrict future site use*Durable ICs -For "higher risk" sites (100-500 mrem/yror > 100 yrhalf life

-A dverse natural p rocesses (e.g., erosion

RESTRICED RELEASE FINANCIAL ASSURANCE ASSURANCE-10CFR20.1403(c) 10 CFR 20.1403(c)-NUREG-1757, Vol. 3

-Alleviates the need for exemptions for exceeding doses listed below(SOC) below (SOC)-Exceed 25 mrem/yr(1402, 1403(b), 1403(d)(1)(i)(A))

-Restrictionsrequiredper1403;reducedosestoALARA Restrictions required per 1403; reduce doses to ALARA-Commission approval after considering public and EPA comments*Exemptions

- Asystemofcontrolstoensuresafety A system of controls to ensure safety-25 mrem/yrwith restrictions -Legally enforceable and durable ICs -EBs designed for site
-Monitoring and maintenance; 5-year rechecks
-Independent third party/government backup to site owner/custodian
-Financialassuranceforthirdparty Financial assurance for third party-Dose "caps" if ICs fail: "safety net"
-Remain licensed, if needed 14
