3. Approach to Radiation Protection • Environmental Monitoring - Stack and site perimeter for particulate and tritium. • Facility Surveys - work areas, waste packaging, Mock-up, RWHF, adjacent facility areas. • Personnel Monitoring - bioassay, whole body count, digital dosimeters, whole body scan for beta gamma (when exiting work area). • Job Coverage and Monitoring - one HP per 4-5 workers (3 tasks simultaneously), exposure monitoring to tritium and gamma, surface monitoring. • Release of Equipment - scan for beta-gamma (no detectable), 1,000 dpm/100 cm2 for tritium surface contamination. (may change to 10,000 dpm/100cm2). • Radioactive Waste Characterization - smear for tritium by system and estimate surface area. Gamma survey on loaded containers for other radionuclides. • Containment - tents for diamond wire cutting using engineered ventilation. • Cutting - Baseline plan to cut all metals with shears except for VV. PF coils and pump ducts.

4. HP Personnel Assignments • HP Manager - regulatory, instrumentation, and dosimetry support. • Health Physicist - (FTE) - Procedures, whole body counting, field support. • Lead Technician - (0.7 FTE) Supervision, procedures, RWPs, survey review. • 5 Field Technicians (FTE) • Count Room Technician • Compliance Surveys/Waste Support/Release • 3 Job Coverage • Dosimetry Supervisor - Bioassay, beta-gamma TLD, digital dosimetry. • Laboratory - DATS, Beta-gamma counting, gamma spec., oxidation. • Instrument calibration • Clerical (0.5 FTE) - record keeping, dosimetry support

5. Safety Personnel Assignments • Site Industrial Hygienist - guidance and regulatory oversight - OSHA and NIOSH. • Assistant IH - (FTE) - training, procedures, permits, field sampling and monitoring. • Construction Safety - (FTE) field implementation of personnel safety. • Clerical (0.5 FTE) - record keeping, administration of permits.

6. Equipment • Whole body counting - Helgeson • Exit monitoring for beta gamma - Helgeson, Aptec or Eberline • Tritium-in-air Monitors - Scintrex (2) • Bicron Micro-REM meters (4) • Beta-Gamma contamination survey meters (3) • Particulate air sampling - environmental and field (IH and HP) • Digital Dosimeters • General supplies - smears, vials, cocktail, etc. • Contamination Control - bags, herculite, decon equip. • Hearing, head, eye, and hand protection • Respiratory protection - lead handling

7. Final Radiological Survey • Wall wipe down or wash (if necessary) • Surface Contamination Measurements • MARSSIM - • Walls, ceiling and floors • Radiation Surveys - characterize facility • Shot Blast Floors

8. Radioactive Waste • 44,658 cubic feet of tritiated and activated material. • 20,833 cubic feet standard waste (B25 boxes) • 23,825 cubic feet special waste (non-standard or no packaging) • Maximum total activity due to activation is <100 Curies • Co-60, Co-57, Mn-54 • Fe-55 (beta emission only) • Total tritium inventory is 8,204 Curies • “Not active” inventory, entirely within VV. • Radioactive Waste Handling Facility • Storage of valuable equipment (primarily activated). • Storage prior to off-site transport for disposal. • Large items will be shipped directly off-site from TFTR through NE door.

9. Waste Management Personnel • Waste Manager - coordinates all waste packaging, transportation and disposal. • Waste Technicians (2 FTE) - provide materials, monitor and assist with packaging. • Support - Mgmt, D&D Head, waste technicians, clerical, budget. • Mgmt - Regulation, DOE, Disposal facility • Head of D&D - Health Physics, safety, and rad waste • Waste Technicians - material handling, prepare for transport • Clerical - administration of legal documents related to burial • Budget - monthly tracking of ER/WM D&D Activities

10. Container Requirements • 4 ft. wide, 4 ft. high, 6 ft long metal containers • IP- 1, IP-2, and Type A. • Type A have bolted closure. • 55 gallon drums - primarily for compactible and liquid waste. • Stainless steel kegs - tritiated oil • Special Containers • Vacuum vessel segments • RF pump ducts • No containers - TF coils, PF coils, columns and lintels • Material Recycle - stainless, copper and titanium • National Center for Recycle • Private industry

11. Transportation • All shipments will be LSA or Type A quantities • Limited to 1080 Curies of tritium for Type A container • Dose rate limit of 200 mR/hr - no issues, VV at 50 mr/hr (May 1999). • Normal shipments - 40,000 lb. maximum payload • Special shipments • Vacuum vessel segments (10)- special permits (size and weight). • TF coils (20) - special permits (size and weight). • Current contract with TRISM - Expires April 2002 • Need to procure contractor for special transportation - logistics, permits, intermodal evaluation, bonding, heavy haul.

12. Disposal • Hanford site for all disposal - Others are availablew/ DOE approval. • Cost estimates are based on $20 per cubic foot • High Integrity Containers - if >100 Curies/ cubic meter • No new waste streams are expected • Mixed waste - contingency but not expected (pump oil removed). • Scheduling July visit to Hanford - present D&D waste information. • Certain shipments will require special handling at Hanford • Vacuum vessel segments (10) - special permits (size and weight). • TF coils (20), PF coils, columns, lintels.
