Effl nts Radiation Protection Section, DRSS Inspection Summary: Inspection on September 14-16, 1988 (Inspection Report No. 70-820/88-03).

Areas Inspected: Special announced inspection by region-based inspectors for the purpose of obtaining water samples from selected monitoring wells, to examine the status of decommissioning the site and the buildings and to conduct a verification survey of outside areas of the facility.

Results: No violations were identified. The licensee completed removal of additional contaminated soil from areas inside (Grid No. B-126) the restricted area fence. The inspector conducted a verification survey and obtained soil samples for analysis.

2. Monitoring Well Water Sampling The inspector observed the sampling of each monitoring well. Prior to sampling, each well was pumped for about 5 minutes in order to clear the -

lines of standing water. This water was discarded. The licensee took a five (5) gallon sample from each well and the NRC samples (one (1) gallon) were taken (split) from the licensee's samples.

a. Well Water Sampling The conditions under which each well sample was obtained are shown in the enclosed table (Attachment 1).

b. Sample Analysis The well water samples marked in the table (Attachment 1) with an

• were split by the NRC inspector with the licensee. Samples obtained by the NRC were sent to the USDOE Radiological and Environmental Services Laboratory (RESL) located in Idaho Falls, Idaho, for analysis. The licensee's samples were sent to Controls for Environmental Pollution, Inc., located in Santa Fe, New Mexico.

Samples in excess of 5 picoeuries/ liter gross alpha and/or 50 picocuries/ liter gross beta will be further analyzed, as necessary, for strontium-90, cesium-137, uranium isotopic, thorium isotopic, and gamma spectroscopy.

c. Sample Analysis Results The sample analysis results from each laboratory will be compared by Region I. This comparison and a trend analysis, utilizing results from prior years, will be addressed in a subsequent inspection report.

3. NRC Independent Review

a. Observations Concerning the Status of Site Decontamination 4

During Inspection No. 70-820/88-01, the inspector conducted radiation surveys and took soil samples of Grid No. B-126 (see ',

Attachment No. 2). Each soil sample was mixed and split with the licensee. The NRC samples were packaged and sent to the NRC r contractor's, Oak Ridge Associated Universities (0RAU), laboratory j for analysis.

s

3 The analysis results for the samples analyzed for Grid No. B-126 are as follows:

Sample Analyses Concentration (pCi/ gram) by U-234 U-235 U-238 Southwall ORAU 2436 78 94 20 9.7 5.2 before cleanup CEP 960 2 35.5 1.7 -

Southwall ORAU 2733182 99 20 8.214.8 after cleanup CEP 997 4 43.6 0.9 -

Composite ORAU 40.4 0.3 1.410.2 0.4 0.1 CEP 35.2 3 1.410.9 -

Subsequent to that inspection, the licensee took additional remedial action and removed additional soil from the southwall of Grid No. B-126.

During this inspection, the inspector conducted radiation surveys of Grid No. B-126 at the surface and at 1 meter above the surface. Radiation levels were found to be at background levels (1000-2000 counts per minute), using a Ludlum Model 16 Analyzer with a sodium iodide crystal detector. A soil sample taken from the south wall was mixed and split with the licensee. The NRC sample was packaged and sent to ORAU for analysis. If the analytical results are lower than the NRC guidance value of 30 picocuries total uranium per gram of sJil, Region I will recommend that NRC-NMSS release the licensee's outside area, within the restricted area fence, for unrestricted use.

4. Licensee Discussions The inspector held continuing discussions with Mr. K. Helgeson during the inspection. The findings were presented as they were identified. At no time during this inspection was written material provided to the licensee by the inspector.
