Indian Point NPP Entergy Apr 24, 2006 IPEC-CHM-06-012 MEMORANDUM TO: D. WILSON - CHEMISTRY SUPERINTENDENT JJ, FROM: S. SANDIKE - Sr. CHEMISTRY SPECIALISTY
SUBJECT:
UPDATED GROUND WATER DOSE EVALUATION - APRIL 2006 Based on the detection of Sr-90 in monitoring wells MW-37 and MW-50, a decision was made to evaluate whether the existing assessment of offsite dose was still appropriate. The assessment method is the same; that is, it uses a water balance method, where total rainfall in the Indian Point watershed area is partitioned between groundwater (GW) from infiltration, and storm water (SW). The assessment addresses the approximate flows of GW and SW into various areas of the site, based on physical size and locations of the reactor units.
The inputs to the assessment have changed in some cases. For example, tritium going through the Unit 2 area had been based on monitoring well data in the transformer yard (i.e., MW-1 11 and others). More recently, the wells along the riverfront area have been completed, and the values from wells MW-36, 37, 49, 50 and MW-52, are considered more relevant to the actual releases to the Hudson River. As a result of the more recent data, and the fact that Sr-90 was detected in the riverfront wells, the inputs to the assessment have changed. Details of this assessment are attached.
The resulting annual dose summary indicates very little change from the March 2006 assessment:
Parameter: '-'March2006 Eval -';April 2006 Eval LPercentimit"I.
Total Body Dose 2.1E-3 mrem 2.5E-3 mrem 0.08%
Adult Bone Dose 9.7E-3 mrem 1.1E-2 mrem 0.11%
Doses are still approximately 0.1% percent of the applicable NRC effluents limits of 3 millirem per year (whole body) and 10 millirem per year (highest organ). The actual curies and doses will still, of course, be included in the annual effluent report. Our site hydrologist will also continue to pursue a more detailed method of determining precise flow through each effected well, and, when completed, this method will be incorporated into the dose model for ongoing application.

Update on Assessment of Offsite Dose from Groundwater and Storm Water Pathways Based on the detection of Sr-90 in monitoring wells MW-37 and MW-50, a decision was made to evaluate whether the existing assessment of offsite dose was still appropriate.
The assessment method is the same; that is, it uses a water balance method, where total rainfall in the Indian Point watershed area is partitioned between groundwater (GW) from infiltration, and storm water (SW). The assessment addresses the approximate flows of GW and SW into various areas of the site, based on physical size and locations of the reactor units.
The inputs to the assessment have changed in some cases. For example, tritium going through the Unit 2 area had been based on monitoring well data in the transformer yard (i.e., MW- 11I and others). More recently, the wells along the riverfront area have been completed, and the values from wells MW-36,37,49,50 and MW-52, are considered more relevant to the actual releases to the Hudson River. As a result of the more recent data, and the fact that Sr-90 was detected in the riverfront wells, the inputs to the assessment have changed. The current inputs are shown in Table 1, below. The "Cale Sheet" references in the "Comments" column refer to spreadsheets developed by Chemistry to calculate the offsite doses in different pathways.
