1. Comanche Peak plans to implement the referenced EPRI Report. Had to analyze H-3 concentrations over the past couple of years for primary RCS and secondary cooling to understand oils that could be determined to have concentrations of H-3 (and C-14) below the operational state of the art limit. Evaluating waste streams that are documented for Part 61 requirements can help with determining release of other hard to detects such as Ni-63 and Fe-55. Very useful to develop flow diagram specific to your plant(s) as the EPRI Report diagram may have unusuable/confusing steps.
2. Currently revising procedures. 3. Plan to free release eligible waste oil once established by procedures.

Has your facility implemented or are there plans do implement EPRI 300214471, Methodology for the evaluation of Used Oil for Radiological Contamination: Focusing on Hard-to-Detect Radionuclides, Tritium, and Carbon-14? 2. Do you have a process that is different from that used in the EPRI report for releasing waste oil or oil samples; ie one that accounts for H-3 and C-14? 3. Do you free release waste oil?
