Dear Mr. Keppler:
In the Matter of the Tennessee Valley Authority Docket Nos.
50-327 50-328 SEQVOYAH NUCLEAR PLANT (SQN)
SYSTEM HEATVP This confirms our telepnono call of September 16, 1987, during which I informed you of my intent to initi.ate activities at SQN unit 2 leading to the nonnuclear heatup of plant systems.
I am taking, this action to establish the capability of the SQN systems and the operating staff to support the later return of the plant to operation after its extended shutdown period. It will also provide an opportunity to identify problem areas which are likely to
- occur, and take appropriate corrective actions.
These activiti.es will include bringing ongoing work to logical closure, conducting comprehensive valve alignment, and heatup of the plant to full system temperature and pressure using nonnuclear pump heat.
During thi.s period, which should last approximately five to six breeks, I intend to conduct prim."ry and secondary system testing and equipment checkout to identify any equipment problems whi.ch might impai.r future power operations.
As you are aware, we have previously reviewed deficiencies using the approved restart cri.teria.
For the nonnuclear
- heatup, wo will assess both open deficiencies and new issues using the technical specifications operability definition to comply with technical specification requirements for mode changes.
The move toward system heatup wi.ll require that cable testing, hanger modificati.ons resulting from the regenerated civil support calculations, and resoluti.on of IDI issues be deferred.
A document is being prepared to support exi.sting conditions for those items.
During the heatup period wo will be able to plan these modificati.on programs in greater detail to feei.litate their effective completion after the cooldown.
These and other unfinished SQN restart items will be comploted at that time to support plant restart.
Any issues identified subsequent to nonnuclear hoatup will be addressed using technical speci.fication requi.rements.

Mr. James G. Keppler Septembor 28, 1987 Sequoyah employees are roady to make the transition to normal operating conditions, and I am confident in their abilities to prepare the system for operation.
Several pending licensing actions need to be comploted before we begin the heatup and change to mode 4.
These will bo discussed with your staff along with the dotails of the heatup plan at.
SQN sito prior change to mode 4.
Thos'~ activities are in consonance with tha NRC staff in its 10 CFR 50.54(f) letter to TVA'dated Septesber 17, 1985.
