Subject:
Arkansas Nuclear One - Units 1 & 2 Docket Nos. 50-313 and 50-368 License Nos. DPR-51 and NPF-6 Response to Inspection Reports 50-313/80-10 and 50-368/80-10 (File:
0232,2-0232)
Gentlemen:
In response to the Item of Noncompliance included in the subject report, the following is provided.
NOTICE OF VIOLATION Based on the results of an NRC inspection conducted during the period of May 22 through June 21, 1980, it appears that certain of your activities were not conducted in full compliance with NRC regulations and the con-
~ '
ditions of your licenses DPR-51 and NPF-6, as indicated below:
A.
Technical Specification 6.8.1 requires that, " Written procedures shall be established, implemented, and maintained covering...
a.
The applicable procedures recommended in Appendix "A" Regu-latory Guide 1.33."
1.
Radiation Protection Procedure 1602.18, Smear Sampling, has been established in accordance with the Technical Specifica-tion.
OC/
i 5
Step 6.0 in this procedure states, " Monthly smears taken
/((
during the Reactor Auxiliary Building Survey will be counted for alpha radiation.
If alpha contamination is found, more po80 5 c^55' q
_ e - com e - - eeve -
Mr. K. V. S:yfrit July 29,1980 extensive and more frequent surveys will be made for alpha."
Contrary to the above, during the months of April and May, 1980, the licensee failed to count smears taken during either the Unit 1 or Unit 2 Reactor Auxiliary Building Sur-veys for alpha radiation.
This is an infraction.
(313/80-10-01);(368/80-10-01).
RESPONSE
Alpha surveys of the Unit 1 and Unit 2 Reactor Auxiliary Buildings were not performed because they were not included on a routine survey schedule.
Alpha surveys have now been incorporated in the Health Physics monthly routine radiation survey schedule which will assure future compliance with Radiation Protection 1602.18.
Full compliance was achieved July 23, 1980.
Radiation Protection Procedure 1602.27, Anti-C Laundry Handling and Monitoring, has been established in accordance with this Technical Specification.
Step 5.0 in this procedure states that all laundered clothing
... with less than 1.0 mrem /hr of fixed contamination may be released for normal use.
Items with fixed contamination levels between 0.1 mrem /hr and 1 mrem /hr will be segregated for use in highly contaminated areas (outer set of coveralls, etc.).
For items above 1 mrem /hr the Health Physics Supervisor will specify final storage or disposal."
Contrary to the above, the licensee failed to adhere to the procedural requirements relating to the handling and monitoring of laundered Anti-C clothing in the Unit 1 and Unit 2 controlled access areas. Specifically, on June 5,1980, two (2) out of ten (10) sets of Anti-C clothing sampled were found to have fixed contamination levels in excess of 1.0 mrem / hour and five (5) of the remaining eight'(8) sets of clothing were found to have fixed contamination levels in excess of 0.1 mrem /hr. None of the sets of Anti-C clothing found to have fixed contamination levels in excess of 0.1 mrem / hour were segregated for use in highly con-taminated areas.

RESPONSE
4 Laundry personnel were given additional training in the proper radiation survey techniques for release of Anti-C clothing for reuse after laundering.
In addition, Health Physics conducts weekly routine radiation surveys on Anti-C clothing which is stored in Controlled Access and is available for reuse. Any Anti-C clothing found to be contaminated in excess of procedural L
r limitsLis removed from service.
i Full compliance was achieved on July 21, 1980.
NOTICE OF VIOLATION Section 19.11(a)(4) of 10 CRF 19 requires that the licensee shall post i
copies of any Notice of Violation and the licensee's response thereto for items of noncompliance involving radiological working conditions.
Contrary to the above requirement, the licensee failed to post the Notice of Violation or his response to the Notice of Violations for infractions 1 and 3 reported in IE Inspection Report 50-313/80-06; 50-368/80-06, both of which involved the control of radiological working conditions.
i This item is a deficiency.
(50-313/80-10-03; 50-368/80-10-03).

RESPONSE
The notice of violations and AP&L responses for infractions 1 and 3 reported in IE Inspection Report 50-313/80-06 have been posted.
I Appropriate administrative controls have been developed to ensure responsibility for this posting is clearly defined by AND Admin-i-
istrative procedures.
Full compliance was achieved on July 24, 1980.
NOTICE OF VIOLATION Based on the results of an NRC inspection conducted during the period of May 22 - ' June 21,1980, it appears-that certain of your activities l
were not conducted in full compliance with NRC regulations and the con-l ditions -of your -license (NPF-6), as indicated below:
T i
../...m.
Mr. K. V. Seyfrit July 29,1980 Technical Specification 6.8.1 requires that, " Written procedures shall be established, implemented, and maintained covering...a.
The applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33."
Operating Procedure 2103.15, Reactivity Balance Calculation, has been established in accordance with this Technical Specification.
Step 1 of Work Sheet C-5 requires that Attachment C-8b be used to determine required boron concentration when reactor coolant system (RCS) temperature is between 3000F - 525 F.
Contrary to the above, on April 18, 1980, while conducting shutdown margin calculations with the RCS temperature at 5020F, Attachment C-8a was used, causing a non-conservative error in the calculation of required boron con-centration.
This is an infraction.
(368180-10-04).
RESPONSE
A review of the reactivity balance procedure shows that the required concentration for the required shutdown margin (5.5% Ak/k available) was 873 ppmB, actual concentration was 919 ppmB, thus actual shutdown margin was adequate.
During counseling of the operator and shift supervisor involved, it was determined that the shutdown margin calculation was intended to project final condition shutdown margin conditions for completion of the heatup evolution in progress. Previous shutdown margin cal-culations indicated the acceptability of shutdown margin for previous operating modes.
Procedures have been revised to require specific notation on shutdown margin worksheets to signify if the calculation is a projected, versus actual, value.
Full compliance was achieved on July 22, 1980.
Very truly yours,
[
