Dear Mr. Denton:
DOCKET NUMBERS 50-483 AND 50-486 CALLAWAY PLANT, UNITS 1 & 2-FINAL SAFETY ANALYSIS REPORT RESPONSES TO NRC 00ESTION 260.71C The attached is a response to your question 260.71C which was transmitted by a letter from R. L. Tedesco to J. K. Bryan dated Augu'st 12, 1981.
Portions of this response were discussed'with Dr.
G.
E. Edison, Mr. J.
Spraul and Mr. C.
Block of your staff in a telecon September 29, 1981.
. Based on the attached response, Union Electric will revise our position on Regulatory Guide 1.33, Revision 2,
" Quality Assurance Program Requirements.(Operation)", currently stated ia the Callaway FSAR Site Addendum, Appendix 3A.
The revised position will include
,an added sentence which states, "The activities described in Appendix'A (to. Regulatory Guide 1.33) in Sections 7e, 7f, 7g, 8, 9, and 10 which relate to the health physics program described in the Callaway Radiation Protection Plan are not considered to be safety related and are exempt from'the. Operations QA program.
The administrative controls of'the health physics program are discussed in the Union Electric response to NRC question 260.71C which is discussed in the Callaway Site Addendum ' Responses to NRC
-Questions'".
This.information and the attached response are hereby
!.ncorporated into the callaway Application and will be incorporated into the next revision of the Callaway FSAR Site Addendum.

-Item 260.71C' Section 17.1.2.2 of the standard format (Regulatory Guide 1.70) requires the identification of safety-related structures' systems, and components
~
controlled by the~OA. program.
You are requested to supplement and clarify Table 3.2-1 of the Callaway FSAR in accordance with the following:
.a.
The following items do not appear on FSAR Table 3.2-1.
Add the appropriate items to the table and provide a
-commitment that the remaining items are subject to the Pertinent requirments of the FSAR operational quality assurance program or justify not doing so.
- a.1 Safety-related masonry walls (IE Bulletin 80-11).
Callaway Position: There are no safety related masonry walls utilized in the Callaway-design.
Non Category-I walls are included in Section 17D of the D&C QA Program and Table 17.D.1 of the Operating Quality Assurance Manual.
a.2
. Biological shielding within the fuel bldg.

a.7 Radiation shielding doors.
Callaway' Position: AlreEdy in' Table 3.2-1, Section 8.2.
(Our position is that this-item is not safety related).
a.8 Radiation monitoring (fixed and portable).
Callaway Position: It is Union Electric's position that items 8-16 of 260.71c(a) should not be included in Table 3.2-1, or be subject to the requirements of the operational quality assurance program.
Union Electric does feel that NUREG 0761, " Radiation Protection Plans for Nuclear Power Reactor Licensees" Draft Report, March 1981, which is presently in draft form and out for comments, provides the necessary guidance in formulating the Callaway Radiation Protection Plan.
The Callaway Radiation Protection Manual (CRPM) and Radiation Protection (RP) procedures together will constitute the Callaway Radiation Protection Plan (CRPP). outlines the proposed CRPM, The outline lists the major areas to be addressed in the manual.
It is intended that the CRPM will be a concise statement of the Callaway Radiation Protection Plan that can be understood by all plant personnel.
The manual will be written in general and brief terms with the specifics of the plan to be addressed in the implementing RP procedures.
The Callaway Radiation Protection Plan will be developed in accordance with applicable regulatory requirements, regulatory guides, industry standards,'and accepted p
industry practices, and will incorporate sufficient managerial and administrative controls to ensure that a high level of radiation protection is provided.
outlines the implementing procedures.
.These procedures have been broken down into areas as recommended by the NUREG.
It is intended that administrative controls will be 260.71C-2 E

implemented via incorporation into administrative and programmatic level "s,
procAdures which will receive onsite I
Reviewz Committee (Plant Review Group) review and approval To verify that-radiation protection functions are being performed as required and that a high level of radiological safety l
is maintained, pericdic review and audit of the radiation prott: tion program will be performed by an independent audit group of Union Electric Nuclear. Engineering (i.e.,
.the corporate health physics group or their consultant).
The General Office Quality Assurance Group will review the activities and Audit program of the independent audit group to assure that appropriate audit procedures are established and implemented.
The performance of audit and review of the areas identified in items 8-16 to assure program effectiveness is consistent with the position of NUREG 0761.
The audit program will be conducted in accordance with established auditing principles:
1.
use of inspectors / auditors with training and expertise in the area being audited 2.
use of audit personnel with no responsibilities or " vested interests" in the areas being reviewed 3.
documentation and review by management of audit results and findings 4.
performance of corrective or followup actions as appropriate Additional quality assurance for items 8-16 of 260.71c(a) are built into RP procedures utilizing quality
-assurance provisions from regulatory guides.
An example is the respiratory protection program.
Quality assurance for procurement of respiratory equipment is maintained

SNUPPS-C by the purchasing of only NIOSH certified equipment.
In complying y,
withl Reg. Guide 8.15, additional quality ass.urance is established.in the r'espiratory protection program.
