Nuclear Power Regulatory Overview The Keys To Our Success By Bob Wills RRPT GEL Laboratories, LLC
REMP-RETS & 10 CFR 61 Activities NRC – ODCM – REG Guides – NUREG-BTP’s Isotopes of Concern (How Hard To Look) QA/QC Regulatory Requirements Review Rad-Waste BTP & REMP BTP MARLAP Key Objectives
Classification of waste for near surface disposal Considerations given to long lived radionuclides and their shorter lived precursors (Parent to Daughter) Consideration must be given to the concentration of the radionuclide Consideration must be given to the physics form of the radionuclide (Normal or Special Form) Key Elements Outlined In Title 10 CFR 61
C-14 Ni-59 Nb-94 Tc-99 I-129 Pu-241 Cm-242 Alpha emitting nuclides with T1/2 greater than 5yr All nuclides with T1/2 less than 5yr H-3 C0-60 Ni-63 Sr-90 Cs-137 Key Isotopes For Waste ClassificationAs Noted In 10 CFR 61.55
Radioanalytical technology for 10 CFR 61 selected radionuclides Analytical methods for C-14, Co-60,Ni-63/59, Tc-99, Sr-90, Nb-94, I-129, Cs-137 Additional isotopes Be-7/10, Al-26, Cl-36, Mo-93, Cd-109/113m, Sn 121m/126 NRC NUREG 6239
Limits as noted in the BTP page 5 are 0.01 times the value as noted in Table 1 or Table 2 GEL’s administrative limits are 1000 times lower than the required limits Lets review the values in BTP page 5... How low do you need to gofor 10 CFR 61 isotopes?
Within the ODCM you have license requirements for analytical testing The Environmental Monitoring section lists requirements for interlaboratory comparison programs This may apply to 10 CFR 61 programs Would this be a good work practice for INPO? Analytical Requirements in the ODCM
Gross Alpha / Beta (Air Samples) Tritium (Ground and Drinking Water) Co-60 (Ground and Drinking Water / Food) Cs-137(Ground and Drinking Water/ Food) I-131 (Milk and Air Samples) Ni-63 (Ground and Drinking Water) Fe-55 (Ground and Drinking Water) Sr-89 & 90 (Ground and Drinking Water Key Isotopes for REMP
All LLD’s (MDC) listed are “a-priori” or prior to the count (page 40 NUREG-1301) guidance for ODCM Limits as noted in the REMP BTP NUREG-1301 page 64 Table 3.12-2 All programs are driving MDC’s well below the required limits Many plants are requesting Tritium at 150 pCi/L How low do you need to go for REMP analysis?
