Key Objectives

• REMP-RETS 10 CFR 61 Activities
• NRC ODCM REG Guides NUREG-BTPs
• Isotopes of Concern (How Hard To Look)
• QA/QC Regulatory Requirements
• Review Rad-Waste BTP REMP BTP
• MARLAP

3
What Factors Drive QA/QC in US Nuclear Facilities?
4
Key Elements Outlined In Title 10 CFR 61

• 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)

5
Key Isotopes For Waste ClassificationAs Noted In
10 CFR 61.55

• 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

6
NRC NUREG 6239

• 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

7
How low do you need to gofor 10 CFR 61 isotopes?

• Limits as noted in the BTP page 5 are 0.01 times
  the value as noted in Table 1 or Table 2
• GELs administrative limits are 1000 times lower
  than the required limits
• Lets review the values in BTP page 5...

8
Analytical Requirements in the ODCM

• 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?

9
Key Isotopes for REMP

• 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

10
How low do you need to go for REMP analysis?

• All LLDs (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 MDCs well below the
  required limits
• Many plants are requesting Tritium at 150 pCi/L
