APPLICANTS' RESPONSES TO RICHARD WILSON'S INTERROGATORIES ON CONTENTION IVC (SECOND SET)

Applicants Carolina Power & Light Company and North Carolina Eastern Muncipal Power Agency, pursuant to 10 C.F.R.

Section 2.740b, hereby submit the following responses to

" Richard Wilson Interrogatories To Applicant (Second Set)."

The provision of answers to these interrogatories is not to be deemed a representation that Applicants' consider the informa-tion sought to be relevant to the issues to be heard in this proceeding.

ANSWER TO GENERAL INTERROGATORY AND RESPONSE TO REQUEST FOR PRODUCTION OF DOCUMENTS GENERAL INTERROGATORY. For each of the answers you provide to the following interrogatories please give in footnote form each document (including all relevant page citations) you used in formulating the answers and you would use in refuting the contention during this proceeding. Please use the definition of document which you offered on page 3 of your January 31 interrogatories to me. Please produce all B306070291 830602 PDR ADOCK 05000400 0 PDR

• l documents mentioned and permit copying'and inspection by me or my agent. Please state the name, title, and employer of each person who contributes to the answers. Please identify explicitly any models or assumptions used in your answers.

Please include all calculations in their entirety. Please 1 footnote every fact in every answer. '

RESPONSE: All such facts, documents, models and assump-tions relied upon are indicated within each response to the specific interrogatories on Contention IVC. Ronald L. Shes.rin; Project Specialist - Environmental; Carolina Power & Light Company, prepared Applicants' responses to the specific interrogatories on Contention IVC. Other persons who contribu-ted to each response are also identified within each response to the specific interrogatories on Contention IVC.

The requested documents will be made available at the Harris Energy & Environmental Center, Route 1, New Hill, North Carolina 27562. The documents will be made available during Carolina Power & Light Company business hours (or such other mutually agreeable time). Appointments to inspect the docu-ments may be arranged by telephoning Hill Carrow at 836-6839, at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before the requested inspection. Applicants will maintain the requested documents assembled in Carolina Power & Light Company offices, available for inspection by Mr.

Wilson, for a reasonable time (i.e., through July 1, 1983),

after which they will be returned to their place of origin.

Inspected documents which Mr. Wilson wishes to have copied will be reproduced by Carolina Power & Light Company on a schedule compatible with other demands for duplicating

l equipment. A Carolina Power & Light Company employee will be available during the inspection in order to receive any requests for copying. Copies of such selected documents will then be furnished to Mr. Wilson upon payment of 7 cents per page, to meet Carolina Power & Light Company's cost of repro-duction.

ANSWERS TO INTERROGATORIES ON CONTENTION IVC INTERROGATORY NO. IVC-1. With respect to the L.L.D.

equation given in table 4.12-1 of NUREG 0472 please answer the following questions.

(1). Why are 95% and 5% selected as the error levels?

ANSWER NO. IVC-1(1). 95% and 5% are the normally accepted standards used in sampling procedures. Any errors that may be introduced into the total dose assessment program using these confidence levels are insignificant when compared to the variance introduced by natural background and other sources of public radiation exposure.

(2). This form of the equation suggests that 6 sample =6 blank =6. Is this reasonable to assume at this preliminary stage?

ANSWER NO. IVC-1(2). Yes. The Lower Limit of Detection is a determination of that point at which the analytical system can distinguish sample activity from background activity. At this interface CT sample = d- blank (background).

Therefore, the magnitude of background activity is a major factor governing the system's ability to detect non-background activity. It must be remembered that, because the L.L.D. is a

given requirement, if background is high, Applicants will be required to compensate by taking larger samples, increasing efficiency or improving chemical yield in order to meet the sensitivity specified in table 4.12-1 of NUREG-0472.

(3). Since the L.L.D. is an a priori limit, how are observed. concentrations estimated, i.e. by confidence intervals or determination limits?

ANSWER IVC-1(3) . By confidence intervals. ,

CONTENTION IVC-2. With respect to the Sb form in the L.L.D. equation given in table 4.12-1 of NUREG-0472 please answer the following questions.

(1). Since Sb is an estimated quantity, what are the details of estimation procedure'?

ANSWER IVC-2 (1) . Sb is not an " estimated quantity." Sb is measured prior to the analysis of each environmental sample.

It is calculated by making a count without an active sample in the counter.

Sb is the square root of the total count divided by the time over which the background is counted.

(2). Is the theoretical variance that you refer to usually of smaller or larger magnitude than the Sb terms?

ANSWER IVC-2(2). Since an Sb calculation is made at the time of each analysis, theoretical variability plays no part in the calculation for the analysis. Performing a background count prior to each sample count neutralizes the effect of weather, seasonable or temporal variability.

(3). Is there any documentation describing how the mean and variance of Sb vary with weather, season or time of day?

ANSWER NO. IVC-2(3). No. The raw data have not been summarized in-this format.

(4). Please. illustrate a particular sampling pathway in detail, examining the precise method of control measurement, the systematic nature of sampling times, and the effects of inclement weather, etc. on the collection process.

ANSWER NO. IVC-2(4). See attached chart.

This chart was prepared by Don H. Edwards, Jr.; Senior Specialist - Environmental; Carolina Power & Light.

INTERROGATORY IVC-3. With respect to the cross-check validation analysis of 6.1.5.5 of the Environmental Report please answer the following questions.

(1). Select a particular example and describe the cross-check process in enough detail to identify how the "mean result of a cross-check analysis" is calculated.

ANSWER IVC-3(1). Example: Environmental Radioactivity Laboratory Intercomparison Study.

Applicants participate in the EPA Environmental Radioactivity Laboratory Intercomparison St'udy and plan to continue to rely predominately on this study in the future.

This program is described in EPA-600/4-81-OO4. (February 1981).

1. A special sample (i.e. liquid for drinking water, filters for air, etc.) is received from EPA.

2. EPA supplies instructions for any special pretreatment required to split the sample into three aliquots.

I

3. Analyses are performed on each aliquot separately.

4. These analyses are returned to the EPA within the specified date for this study.

5. The laboratory supervisor receives the textbook answers from EPA. He compares his results at that time.

6. If he is not satisfied with the comparison, he initiates an investigation to determine the possible cause of the discrepancy.

7. EPA will provide a report showing where Applicants' laboratory stands relative to other participating laboratories.

Notc: The "mean" result of the cross check analysis is calculated-by EPA by averaging the three analyses provided them.

This analysis was prepared, in part, by Dr. Daniel F.

Cahill; Senior Specialist - Environmental Laboratory; Carolina Power & Light Company.

(2). What is the expected delay between error discovery i and correction action?

ANSWER IVC-3(2). The length of delay is totally dependent 4

on the type of error that is determined to have occurred. The delay is minimized as much as possible.

f

-- - ~ _ -

Discrepancies occur infrequently. .One possible cause of those discrepancies that do occur is defective counting standards. These counting standards are re-ordered immediately and replaced as soon as possible.

(3). Does this expected delay depend upon the size and type of error?

ANSWER IVC-3(3). No. The extent of delay is dependent only upon the time required to take the necessary corrective action.
