Presentation Transcript

  1. Metal Moratorium Break Out Session • Presentations: • Andy Wallo: DOE, discussion of status of DOE O 458.1, IFB • James Liu: SLAC Measurement Protocols • IFB, field instruments and surface survey , proxy, PK, MDA < ANSI SLS • Keith Welch: Material Release Protocols JLAB • TBD available, also for liquids and solids • Bob Fairchild: LBNL Metals Moratorium • IFB; if destined for disposal, material is held on-site pending transfer to local landfill • Don Gregory: Release of Materials at ORNL • Activation calculation and/or PK, NaI and Pancake survey • Authorized Limits process for samples • Steve Butala: ANL, An Alternative Disposal Method for Activated PCB Capacitors • Used RESRAD and PK to establish authorized limits and release PCB-laden transformers as hazardous, rather than mixed, waste • Discussions: • Develop a DOE Technical Standard to ensure consistent approach across the complex • MARSAME approach with ANSI levels • Site specific technical bases based on AOI and PK

  2. Metal Moratorium Break Out Session • Endorsement of IFB for release of materials • Materials that are IFB are not subject to further regulatory requirements • Need to have technical basis to support unrestricted release of metals: • Process knowledge • Define field measurement methods • Quantify MDAs for isotopes of interest • ∑i(MDAi / SLi)  1 • Consideration of MARSSIM/MARSAME methodology • Decision at Site Office level

  3. Questionnaire on Measurement protocols • Release criteria • IFB, specific activity levels lower than ANSI SLs • Field instruments • NaI, plastic scintillators for volumetric • Field measurement methods • Direct scan, discrete points, detecting "proxy" isotopes • Graded approach for measurement • PK, or 100% surveys • MARSSIM/MARSAME considerations • Additional verification measurements • Several labs have portal gate monitors • Field gamma spectroscopy, analytic sampling when warranted • Record management • Some labs have a release permit/authorization/form • Impact to each site from metal moratorium

  4. ASW 2010 Workshop Expected Outcome • Goal: Consistent measurement protocols to support unrestricted release of concrete and metals • Questionnaire on Measurement protocols • Discussions of issues, show-stoppers and problems, and solutions that are expected or have occurred in the material release process of each lab • Deliverable: Benchmark report
