1.0 SCOPE This TBD was developed to determine appropriate Derived Concentration Guideline Levels (DCGLs) for embedded and buried piping; it was revised in response to the United States Nuclear Regulatory Comnmission's (NRC) Request for Additional Information (RAI) RAI

47. RAI #47 questioned why a non-probabilistic methodology was used and whether it was conservative. This revision is a total rewrite and therefore contains no revision bars.

2.0 DISCUSSION The objective of this calculation is to determine DCGLs for embedded and buried piping.

Embedded piping: Includes piping that is encased in the basement concrete walls or floors and may include penetrations through anchor blocks for some piping systems.

Buried piping: Are remaining below grade piping systems with a minimum of three feet of cover material at license termination.

As discussed, RAI #47 covered the following:

RAI#47 What is the reason for the use of a different approachfor the pipe DCGLs? Also, provide information on whether the use of mean values fr-om the probabilistic distributions in a deterministic assessment may be non-conservative.

Response: DCGLs for buried piping was re-assessed using the probabilistic mode in RESRAD. The new assessment:

Accounts for all buried pipes currently identified to remain in place;

Accounts for initial soil activities based on the surface area of all buried pipes currently identified to remain in place,

Includes a contaminated zone equal to 1OOm2 in area and 1m in thickness, which adds approximately 20% conservatism to the size of a contaminated zone based on the dimensions of all buried pipes currently identified to remain in place;

Addresses RESRAD parameters identified as sensitive in ENG-HB-001 through the use of 2 5 th and/or 7 5 th percentile values as appropriate for Am-241, Co-60, Cs-1 37, and Sr-90;

" Uses the distributions from NUREG/CR-6697 as input for RESRAD parameters not identified as sensitive in ENG-HB-001; and

Uses input values for contaminated fractions for plant food, meat, and milk that are consistent with the area-adjusted values in ENG-HB-005.

The peak of the mean dose resulting from the current assessment for buried pipe is 9.67e-4 mrem/y. The dose results from the current assessment demonstrate that a DCGL value equal to 100,000 dpm/100 cm- ensures compliance with 10CFR20.1402. The dose associated with all buried pipes currently identified to remain in place will be taken into account during FSS activities (see response to RAI 45).

A limited amount of embedded and buried piping (less than 500 linear feet) is expected to remain post decommissioning. DCGLs for embedded and buried piping are necessary to account for any dose contribution made the survey unit in which the piping is located. Since the end state for the Humboldt Bay Power plant decommissioning will leave a large open soil footprint with only a few site buildings remaining, it made sense to try to connect the residual activity left in piping systems to a volumetric (soil) DCGL. To further this objective, the following assumptions were made:

The integrity of all the embedded and buried piping is completely degraded in year zero.

The activity formerly internal to piping systems is uniformly dispersed in the volume of soil of the piping.

3.0 CALCULATION Piping DCGLs:

2 The DCGL is arbitrarily set to 100,000 dpm/100 cm . Experience has shown that this is a level that is readily detectable without requiring highly specialized instrumentation.

The dose impact of leaving the contaminated piping in the soil was estimated using the RASRAD code developed for the US Department of Energy (USDOE) at Argonne National Laboratory (ANL).

This was done by determining the volume of piping now scheduled to remain, as shown in Table 1.

Total activity (A):

A = Area x DCGL =

= 2,850 m 2 x 1E5 dpn/100cm2 x (I00cm 2/.01mM) x (lpCi/2.22dpm)

= 1.28E10 pCi

The total volumetric activity in pCi/g may be calculated by setting the soil density (p) to 1.56 g /cm 3. The volumetric soil activity (C) in the contaminated zone is given by the total activity (A), divided by the total soil mass (M):

Soil activity concentration (C):

C = A/M

= 1.28E10 pCi/[ 80.7 m 3 x (1E6 cm 3/1m 3 ) x 1.56 g/cm3]

= 102 pCi/g 3.1 RESRAD Note: The sample taken in the off-gas tunnel is one of the higher activity samples. This sample was selected because the beta and alpha activities were sufficiently present to allow for development of ratios from positive data. Buried piping to be surveyed will have analyses performed on scrapings/sediment present in the piping so as to assess that the ratios used are still representative.

A typical nuclide fraction (based on results from the off-gas tunnel) Attachment 1 was used as the input to the RESRAD run. The resultant dose consequence per nuclide is listed below:

This matches the density assumed present in the 2 meter thick contaminated zone. As shown in Figure 1.

COVER MATERIAL CONTAMINATION ZONE Note: For calculation purposes, the calculated total volume was then increased by approximately 20 percent to 100 m3 .

RESRAD reported a peak of the mean dose resulting from this assessment for buried pipe of 9.67e-4 mrem/y. The RESRAD Summary and detailed reports are included as Attachments 2 and 3 respectively.

4.0 CONCLUSION

The DCGL presented for embedded and buried piping (100,000 dpm/100cm 2) provides a conservative estimate of the dose consequence of leaving the piping in place after license termination. The constraints of the conceptual model, i.e., requiring a minimum of 1 meter of cover material above the contaminated zone, render the DCGL only applicable to sub-grade piping.

The calculated dose contribution from the piping will be subtracted from the dose limit (25 mrem/y TEDE) for the survey units that lay atop of the piping system/segment being evaluated.

Dear Ms. Anderson:

N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.

- Indicates analyte is a surrogate/tracer compound.

A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of+/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

-Rank is set to zero if the dose is zero or the correlation matrix is singular.

-R-SQUARE varies between 0 and 1 and is called the coefficient of determination; it provides a measure of the variation in the dependent variable (Dose) explained by regression on the independent variables.
