  1. Direct Dose Determination Methodology for 40CFR190 Compliance Claude Flory Nuclear Technical Specialist III (actually a Health Physicist) Nuclear Analyses and Fuels Millstone Nuclear Power Station Waterford, Connecticut

  2. Millstone Radwaste Storage Areas

  3. Methodology • Assume one Curie of Cs-137 evenly distributed in source volume • Use shielding code to calculate dose to TLD and to site boundary • Determine ratio of doses (Boundary dose / TLD dose) • Dose at site boundary =(TLD reading – Avg Env TLDs) X ratio

  4. 2007 Results • See handout for details • Total direct dose for four radwaste areas = 0.18 mrem • Need to add effluent doses = 0.03 mrem • Total dose = 0.21 mrem • Old method would have given 4.03 mrem
