SUMMARY

REPORT Survey Unit: F8990441, Fuel Pool Piping system Survey Unit

Description:

Operating History: This system transported radioactive fuel pool water through the coolers and clean up demineralizers. This system was designed to be contaminated.

Operating records and the HSA support its status as radioactively contaminated system piping.Site Characterization: Direct measurements were made of the interior surfaces of the system piping which confirmed the presence of plant-derived radionuclides.

Direct measurements of the interior showed a mean gross activity level of 5,190,000 dpm/100 cm 2 and a maximum value of 16,500,000 dpm/100 cm 2.Based on the classification procedure (DSIP-0020) and levels of gross activity reported, the system was determined to be a Class 1 system.HSA Events: N/A Radioactive by design.Survey Unit Design Information:

The Survey Unit Design Parameters are presented in Table I below. The survey unit and measurement locations are depicted on the maps in Attachment

1. Direct measurement locations were spaced at 15cm intervals and 38 m 2 were scanned for 100% coverage.

The instrumentation used for the survey along with the MDC values are listed in Tables 2-1 and 2-2 in Attachment 2.Page 2 of 29 FSS Summary Report F8990441 Table 1. Survey Unit Design Parameters Survey Design Value Comment Parameter Survey Area: Survey Unit: Class: SU Area (m2): Evaluator:

The results including mean, median, standard deviation and range are shown in Table 2. All direct measurements were less than the DCGL. None of the measurements indicated areas of elevated activity.

Measured activity ranged from 1260 to 26111 dpm/ 100 cm 2 , based on the pipe detector efficiency.

The critical value and the results of the Sign Test are presented in Table 4. The sample mean and median values were less than the DCGL. The sample standard deviation was less than the design standard deviation so no additional samples were required.Page 27 of 29FSS Summary Report F8990441 Table 4.

Yes Page 28 of 29 FSS Summary Report F8990441 Survey Unit Investigations and Results: No investigations were required and no investigation results are reported.ALARA Statement:

As stated in Chapter 4 of the LTP, as long as the residual activity within the survey unit is less than the DCGL (i.e. the survey unit average activity is less than the DCGL and the EMC criterion has been met), the ALARA criterion has been met.Changes in Initial Survey Unit Assumptions:The survey unit was designed as a Class 1 structure survey and the sample results are consistent with that classification.

The variability of the survey results was less than the characterization data used for survey design. No potential areas of elevated activity were detected.Conclusion:

The FSS of this survey unit was properly designed as a Class 1 survey based on Table 5-4 of the LTP. The required number of direct measurements was made and the scan coverage met the requirement of the LTP for pipe surveys. No direct measurementsexceeded the DCGL of 100000 dpm/100 cm 2.No investigations were required.The direct measurement data support rejection of the null hypothesis, providing highconfidence that the survey unit satisfied the release criteria and -.hat the data quality objectives were met.It is concluded that survey unit F8990441 meets the release criteria of 1OCFR20.1402.
