Supplement No. 7.

Response to NRC RAI on FSS Final Report No. 7 On March 15, 2004, Maine Yankee submitted a request for amendment (Reference No. 2) to the facility operating license (Reference No. 1) pursuant to 10 CFR 50.90 and in accordance with the NRC Approved License Termination Plan (LTP) for Maine Yankee, to indicate NRC's approval of the release of the Non-ISFSI site land from the jurisdiction of the license. In support of that request, Maine Yankee supplied the information required in LTP section 1.4.2 and 5.9.3. The land area associated with the license amendment request included the entire non-ISFSI portion of the site land. The dismantlement and survey information for the survey units is being submitted to the NRC in FSS Final Reports.

In Reference No. 3, Maine Yankee submitted FSS Final Report No. 7. In Reference No. 4, USNRC requested additional information on technical information submitted in FSS Final Report No 7. This additional information is provided in an attachment to this letter.

ATTACHMENT Maine Yankee Response to NRC Request for Additional Information (RAI) Regarding Final Status Survey (FSS) Final Report No. 7 NRC RAI No. 1-FR-0111 SU 7 Section D describes an elevated area, identified by the State of Maine lvhich necessitated Maine Yankee to remove an additional 1 to 2 feet of soil. During FSS the ISOCS had been used to scan survey the area, and the activity' was determined to be 0. 73 pCi/g Cs-13 7 (belowv the scan investigation level.) As a result of the State of Maine finding, an investigation wvas conducted As a result of the investigation, elevated readings were found in an adjacent area using a SPA-3 detector. The area was sampled in additional directions and depths. One samplefrom a "likely depth of 18-24 in. " had a Cs-137 specific activity of 5.86 pCi/g, which is "above the DCGL, but beloir the DCGLFAI " In Table 2-2, the scan MDCfor the ISOCS is listed as 0. 12 - 0.5 pCi/g.

Since the ISOCS originally determined the activity for this grid/area as 0. 73 pCi/g, the staff has the following comment:

On page 12, of Maine Yankee Engineering Calculation EC-003-04, Revision 1, dated November 11, 2004, it states "conservatively posited that all the activity in an ISOC scan geometry of 3m2 is located in a 1-M2 circular volume of 15 cm depth located just inside the 3m radius of the detector 'sfield of view." Since the elevated sample was from a soil depth of 18-24 inches, the staff questions the use of the ISOCSfor determining the depth of soil to be remediated Please justify the use of the ISOCSfor determining the activity in soil at depths greater than 15 cm.

Also, please provide the procedure for performing the surveys that determine the depth of soil to be remediated Maine Yankee Response:

There were two elevated areas identified by the State of Maine. The first area was identified during-the remediation phase before the survey unit was turned over for FSS. This location resulted in the identification and removal of storm drain piping. Upon further review, Maine Yankee decided to remove an additional 1 to 2 feet of soil from most of the survey unit, as part of the remediation phase. This 1 to 2 feet of soil removal was not necessitated by the State of Maine identified location, but rather Maine Yankee judgement. The second area was located on the other side of the survey unit and was identified during the FSS phase. The ISOCS gamma scan survey result for this area was 0.73 pCi/g Cs-137. This location was subjected to an investigation. This investigation identified elevated activity in such a small areal extent that it was remediated by virtue of the sampling actions. This activity would have met the release criteria.

ISOCS is certainly appropriate for determining contamination at depth up to the limit at which the photons can penetrate the soil and still reach the detector. The depth of soil typically provided in the circular plane geometry is 15 cm. This depth is acceptable based on the remediation protocol which has the area remediated and sampled until the soil activity is less than the DCGL and samples taken at progressively deeper locations are the same or lower than the surface activity (see attached Appendix A - Soil Remediation Protocol). Furthermore, remediated soil is surveyed by ISOCS using the same evaluation criteria as FSS but using a detector distance of 2 m rather than 3 m.

ATTACHMENT Maine Yankee Response to NRC Request for Additional Information (RAI) Regarding Final Status Survey (FSS) Final Report No. 7 Three geoprobe soil samples were taken in the area in question (the second location described above) during site characterization. The geoprobe samples indicated Cs-137 activity at depths not exceeding approximately 24". The FSS investigation instructions required taking two samples at each of 5 locations, one set at the site of investigation, and 4 sets at 90 degree angles from the center location in order to bound the elevated reading. One sample in each set was to be collected at 0-15 cm depth and the second sample was to be collected at 30-45 cm depth. During the investigation.process, the technicians typically used a 2x2 Nal detector to verify the location of the elevated area and to check that the activity at the bottom of the remediated hole has decreased. This process was followed in SU-7. Once the investigation samples had been collected, the area was scanned and a slightly elevated area was found next to (within 12" of) the center sample location. Soil was removed from the location for disposal until the detector indicated no additional activity. A sample of the soil removed was counted and the activity was 5.86 pCi/g. Because the soil was from nearly the same location as the center sample and it was the highest activity collected, it was conservatively used to represent the center location. The technicians recorded its approximate depth as 18" - 24". SU-7 contained gravel fill over a deep layer of clay. Based on the characterization data which did not indicate soil contamination below 24" and the experience of the remediation personnel that the clay layer was the lower boundary of soil activity, no additional sampling was performed.

Even though the elevated area was removed, the sample result from the removed soil was included in the EMC unity rule calculation in Table 3-1 "Investigation Table" as though it had been left. The area applied to this elevated result was conservatively set at 2 m2, even though the actual area was only a fraction of this area. If this elevated activity had not been identified and removed, the survey unit would still have met the release criteria.

NRC RAI No. 2-FR-0111 SU 9 Section C, states that, "the ISOCS is reconfigured and re-evaluated to account for the appropriate shielding effects of vater and metal. " Please provide the technical bases and justification for the changes to the MDC and other survey parameters.

Maine Yankee Response:

The Form 3 evaluation for the presence of pipe and free-standing water in FROI 11 SU-9 is attached (Appendix B). The spectra for the applicable scan grids were re-analyzed and the resulting MDC's determined to ensure they were less than the investigation levels of 0.36 pCi/g Co-60 and 1.0 pCi/g Cs-137. The following is a table of the resulting MDC for each applicable scan grid.

For example, in SU-J0, the ISOCS scan MDC is listed as 0.3 to 0.9 pCi/g with the comment that this is -50% ofthe DCGL. However, 0, 90 pCi/g exceeds the DCGL for Co-60 of 0.86 pCi/g. Please clarify the ISOCSscan MDCsfor each of the survey units.

Maine Yankee Response:

The MDC values for ISOCS scans reported in Table 2-2 range from the lowest to the highest ISOCS MDC's achieved for that survey unit. In many cases, these ranges were nominal ranges which simply bounded the ISOCS MDC's. The following table shows the maximum nuclide-specific MDCs by survey unit, for those survey units which do not already contain nuclide specific ISOCS MDA ranges in Table 2-2. In the future, Table 2-2 will clearly show which MDC applies to Co-60 and which applies to Cs-137 for the final data set.

Appendix A SOIL REMEDIATION PROTOCOL

1.

Survey units are initially excavated to the depth determined by soil characterization data

(# of borings samples). A 5 meter area around the location of elevated readings was removed to ensure that any contamination propagating from the original source was adequately remediated.

2.

Because contamination was assumed to spread from the surface downward (unless evidence to the contrary was found), remediation was performed until soil activity was reduced to background levels or the activity at the bottom of the excavation was diminishing with continued sampling and was below the DCGL.

3.

Remediation measurements using ISOCS were typically made with the detector positioned 2 m above the surface but using the 3 m investigation criteria.

4.

Once remediation was complete, a SPA-3 scan was performed in the remediated area checking for discrete sources of elevated activity.

5.

When these remediation actions were complete, the FSS survey was performed. Soil samples were collected. If ISOCS was used, the area was typically scanned at a distance of 3m or less.
