Reference:
TVA letter to NRC dated January 20, 1988, "Design Baseline and Verification Program (DBVP)"
i During a recent visit to SQN, Gary Zech met with SQN Site Licensing to discuss I
the FSAR periodic requirements. TVA agreed to provide a letter explaining the efforts that have been completed and those that are ongoing to ensure that FSAR periodic requirements are being met. The enclosure describes TVA's 1
efforts in identifying the FSAR periodic requirements. This letter is provided as information only; no new comitments are being made.

The unit 2 -Nuclear Performance Plan (NPP) outlined TVA's comunitment to enhance 4
the maintenance program to improve the preventive maintenance activities.
The reviews included technical specifications, references to vendor manuals, FSAR
]
requirements, and existing periodic maintenance activities (such as Preventive l
Naintenance Instructions, Surveillance Instructions (SI), etc.) versus the Critical Structures Systems and Components (CSSC) equipment list to identify potential omissions from the preventive maintenance program.
Equipment i
identified as not being in_the existing program is being added in accordance with the unit 2 NPP comunitments.
i t
The Restart Test Program was developed to ensure that system design functions were adequately proven through testing. These functions tested included safe shutdown, accident monitoring, and noriaal operation equipment.
The scope of
]
the program encompassed systems or subsystems defined under the Design Baseline and Verification Program with the addition of the flood-mode borabion I
and rod control systems. As stated in TVA's response to.NRC observation 6.16 I
(identified in the referenced letter). TVA will evaluate control loops identified by the Restart Test Program's Functional Text Natrix that were validated by other than sis to determine which control loops should be added l
to the periodic test program.
~
a Also, an enchancement program is being developed by the Plant Operations f
2 l
Review Staff (PORS) that will identify SQN site procedures described in the FSAR. This program will enhance the 10 CFR 50.59 process by identifying the procedures that require an unreviewed safety question determination (USQD).
)
l It will elso aid in reporting of 10 CFR 50.59 evaluations in that only j
revisions to those procedures described in the FSAR will have a USQD performed.
During this review, any plant procedure requiring revision will also be identified for correction. This program will consist of two parts:
1 l
1.
Identify the portions of the FSAR requiring a procedure.
2.
Identify the plant procedure and systems that at: relative to a specific section of the FSAR and identify proceduc9s requiring revision.
The plant will revise procedures identified by PORS in I
accordance with plant instructions.
l The present schedule for completion of this program is May 31, 1988; however, j
this schedule may vary depending on priorities.
In addition, as part of the SQN FSAR verification program to be completed by October 15, 1988 TVA is in the process of identifying the requirements and/or
]
commitments contained in the FSAR. An evaluation of these requirements / commitments will be made to determine the feasibility of the i
requirements /connaitments.
Providing the requirements /connaitments are practical, the requirements / commitments will be incorporated into the appropriate plant procedure. Through the efforts of these programs TVA will ensure that the periodic requirements identified in the FSAR will be met.
