- FINAL STATUS SURVEY F8300143 Survey Unit: F8300143, Interim Onsite Storage Building (IOSB) Outside Area Class 3 Survey Unit
Description:
Operating History:
Designed primarily to store packaged radioactive waste containers safely, protected from the elements, and maintain radiological dose as low as reasonably achievable (ALARA),
The IOSB possibly stored media of many types, including
- filters, resins, contaminated chemicals, DAW, activated reactor components, contaminated plant components and other contaminated items. The area immediately adjacent to the IOSB structure is an asphalt pavement surface.
The outside perimeter of the asphalt at the interface with the surrounding earthen berm is a thin layer of gunite. The gunite strip is to provide an amount of erosion protection to the outer soil perimeter.
The berm, rather significant grade in some locations extends to the IOSB perimeter chain link boundary.
The total surface including the IOSB structure within the boundary fence is approximately 83,387 ft2 (1.91 acres). Site Characterization:
Based upon the scanning results of the outside asphalt area an elevated area was identified on the asphalt next to the IOSB. Certain spots in the area exceeded the DCGLw but not the DCGLEMC*
The area required remediation.
The Outside area was divided into a small Class 1 Survey Unit, buffered by a Class 2 Survey Unit. The remainder of the outside area was designated as a Class 3 Survey Unit and is the subject of this report. Survey Unit Design Information:
The Survey Unit Design Parameters are presented in Table 1 below. The survey unit and measurement locations are depicted on the maps in Attachment
- 1. Static measurement locations were randomly determined and approximately 45% of the area scanned by gamma scanning.
A total of 7 soil samples were collected from the berm area and analyzed by gamma spectroscopy at an offsite laboratory.
Soil sample data was compared directly to the cesium 137 DCGLw for soil established in the RSLTP of 52 picocuries per gram (pCi/g).
Gamma scanning data was analyzed by determining data points that exceeded a level of 3z. The instrumentation used for the survey along with the MDC values are 1 isted in Table 2-1Attachment2.

14 Survey Results:
A total of 15 direct measurements were made in F8300143 on the asphalt and gunite surface and a total of seven soil samples were collected from the berm area. The results of the static measurements from the asphalt and gunite are shown in Table 2. All of the static measurements were less than the DCGL. All soil sample results were flagged as non-detect with results less than the MDC of l.OE-7 microcuries per gram (uCi/g) or 0.1 pCi/g. The results of the soil samples are contained in Appendix 2 of this report. The maximum score obtained from the gamma scanning was 1.17. 2 FSS Outside Area Class 3 F8300143 FINAL STATUS SURVEY F8300143 Table 2, Static Measurement Results '* .. ,. .. . . Number

The survey design required 14 static measurements for the Sign Test. A total of 15 static measurements were collected on the asphalt and gunite and a total of seven soil samples were collected from the berm. For the static measurements, the critical value and the results of the Sign Test are presented in Table 5. The sample mean and median values were less than the DCGLw. The sample standard deviation was less than the design standard deviation but both values of sigma resulted in a relative shift greater than three (3), no additional samples were required.
All soil sample results were non-detect and less than the DCGLw of 52 pCi/g. Since the soil results were non-detect use of statistical evaluation tools (i.e., Sign or WRS tests) is not required to demonstrate that the survey unit meets the criteria for unrestricted release (MARSSIM Section 8.2, Table 8.2). 4 ***-. ,. * .. : , . * ... ,..*. *.1 ' Table 5, Data Assessment Results Number of Samples:

Pass Survey Unit Investigations and Results:
No investigations were required for either direct or scan measurements and no investigation results are reported.
ALARA Statement:
As stated in Chapter 4 of the L TP, as long as the residual activity within the survey unit is less than the DCGL, the ALARA criterion has been met. Changes in Initial Survey Unit Assumptions:
The survey unit was designed as a Class 3 survey and the sample results are consistent with that classification.
No individual measurement exceeded the DCGL. No potential areas of elevated activity were detected.
==
Conclusion:==
The FSS of this survey unit was properly designed as a Class 3 survey based on the results of the investigation survey. The required number of direct measurements was made and the scan coverage met the requirement of Table 5-6 of the LTP. All of the static measurements were less than the DCGLw. No investigations were required.
All soil sample results were flagged as non-detect with results less than the MDC of l .OE-7 microcuries per gram (uCi/g) or 0.1 pCi/g. The static measurement data support rejection of the null hypothesis, providing high confidence that the survey unit satisfied the release criteria and that the data quality objectives were met. It is concluded that survey unit F8300143 meets the release criteria of 1OCFR20.l402.
