CLARIFICATION OF TMI ACTION PLAN REQUIREMENTS GENTLEMEN:

Pursuant to the conditions of 10 CFR 50.54(f), Georgia Power Company herein submits the confirmation of compliance, with the exceptions and qualifications noted in this letter and its enclosures, requested by Darrell G. Eisenhut's letter of October 31, 1980. The requirements promulgated by that letter, as well as earlier drafts of these requirements, have been the subject of an extensive review by Georgia Power Company, its consultants, and the nuclear industry since their issuance. Our position on each of the items of NUREG-0737 is addressed briefly in.

Georgia Power Company has actively pursued implementation of the requirements which have resulted from the knowledge gained by the study of the TMI 2 accident. We have attempted to be responsible and responsive in our comoliance with both mandated and elective improvements in plant safety.

It is our intention to continue to address all reasonable requirements in a like manner within the limits of existing technology and resource restraints. Many of the requirements of NUREG-0737 are l

complex in nature and have significant, albeit often subtle, plant I

impacts. The complexities of certain proposed solutions and their necessarily l

extended timetables for implementation make an absolute statement of l

compliance impractical and ill-advised at this time. The considerable i -

effort and the numerous revisions required in developing the NUREG-0737 document attest to the difficulty in addressing such issues and schedules for implementation.

We do, however, state our intent to accomplish the implementation of all applicable requirements, as described in Enclosure 1, in their final mutually agreed upon form, per a schedule compatible with that stated in NUREG-0737.

In certain cases, the specific difficulty in meeting the

(

required scheduled is cited in Enclosure 1.

Additionally,.some exceptions 8012280 3g

[

Georgia Poner d U. S. Nuclecr Regulatory Comission December 15, 1980 Page 2 to the specifics of the NUREG-0737 requirements are noted in Enclosure 1.

A complete statement of exceptions will not be possible until more extensive engineering and analysis have been accomplished. Should such exceptions or necessary variances arise in the future, correspondence will be initiated to infom the NRC of their existence and their impact on schedule, and to request NRC concurrence with their resolution.

Should you have any questions or comments on our efforts in this regard, please contact this office.

Very truly yours,

INTENTIONS OF COMPLIANCE FOR NUREG-0737 REOUIREMENTS i

I. A.l.1 - Georgia Power Company (GPC) has had interim Shif t Technical Advisors (STAS) on duty since January 1,1980, as defined in our submittal dated January 25, 1980. STAS, whose training and background meet Technical Specification requirements promulgated by Amendments 79

'i and 18 to the Plant Hatch Unit 1 and Unit 2 licenses, respectively, will be on duty not later than January 1,1981. A description of the current training program which demonstrates conformance with requirements will be submitted by January 1, 1981, along with a description of the long-term STA program.

l I. A.l.2 - GPC has completed implementation of these requirements as they are understood.

I.A.l.3 - GPC met the recommendations of the July 31, 1980, Interim Criteria for Shift Staffing as reported in our letter of October 30, 1980.

t i

The revised interim criteria, issued in NUREG-0737, are undergoing review. GPC plans to meet the intent of this item, but reserves comitment with respect to specifics of implementation until after cur review is completed. The more restrictive requirement of a 12-i' hour break between all work periods, may result in a more probable necessity of deviation as allowed by subparagraph 2 of I&E Circular No. 80-02 and NUREG-0737, than would the criteria for no more than i

24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in any 48-hour period required by the original interim criteria.

I. A.2.1 - This item was addressed by previous correspondence dated August 12, 1980, and September 12, 1980, to Paul Collins of the NRC.

I. A.2.3 - GPC Plant Hatch training programs are in compliance with this requirement as it is understood.

I. A.3.1 - GPC has met currently required items as they are understood and intends to meet those portfor.s applicable to plants without simulators i

by the required date of October 31, 1981, within the limits of i

availability of simulator access. An on-site Plant Hatch simulator is presantly on order and under development.

I.C.1

- GPC is a participant in the BWR Owners Group program for development of guidelines for action on transients and accidents.

It is our intention to comply with the schedule as stated in NUREG-0737.

However, it must be recognized that due to the highly complex nature of such a program, in terms of development and training, the assignment of an absolute completion date is not possible.

I.C.2

- GPC Plant Hatch is in compliance 'with the requirements as they are understood.

I.C.3

- See I.C.2 above.

I.C.4

- See I.C.2 above.

I.C.6_

- GPC intends to comply with the intent of the requirement as it is understood with one known exception at this time. This specific exception is the suggestion that a licensed operator perform the actual tagging or line-ups of systems. A senior reactor operator, normally the Shift Fcteman, develops the system alignment require-ments and authori:es associated tag-out operations. The required physical alignment is the normal duty of a plant equipment operator, who may or may not hold a license. Such an operator is fully qualified to align or verify alignment of any plant system and shall be used for such operations at Plant Hatch.

j I.D.1

- GPC is a participant in the BWR Owners Group Control Room Review program and intends to meet the requirements of this item as under-stood. Complete commitment is reserved until NUREG-0700 has been issued and reviewed.

I.D.2

- GPC plans to meet the intent of this item, but reserves any com-mitment with respect to specifics of implementation or schedule until the issuance and adequate review of NUREG-0696.

II.B.1 - GPC is a participant in the BWR Owners Group efforts toward reso-lution of this item. Currently analyses are underway in support of the use of safety / relief valves (SRVs) as the reactor coolant system vents. GPC intends to meet the requirements of this item as they are understood.

It is believed that the schedule of NUREG-s 0737 can be met, pending acceptable resolution of current questions by analysis.

II.B.2 - GPC has completed an initial shielding analysis and has developed a design to address the results of that analysis. However, the full impact of installation of the designed shielding, when fully evaluated may make such installation undesirable. This point, as well as other outstanding issues in the area of shielding and equipment qualification, must be resolved prior to a commitment to i

meeting the position as stated or the required schedule. This item will be the subject of further correspondence in the future. A commitment to comply with the agreements reached as a result of discussions between GPC and the NRC staff on this question will be made at the conclusion of those discussions.

II.B.3 - GPC intends to meet the requirements of this item as they are understood, and to the extent allowed by ccamercially available equipment. Equipment which will be installed is under develocment and may be subject to as yet unforeseen difficulties in installation and operation. Within the limits imposed by this circumstance, we intend to meet the required schedule.
