l ENCLOSURE PLANT.V0GTLE - UNIT 1 NRC DOCKET 50-424 OPERATING LICENSE NPF-68 NRC NOTICE OF DEVIATION 88-07-01 AND GPC RESPONSE DEVIATION 50-424/88-07-01 "The licensee has an NRC approved Procedures Generation Package (PGP) that is to be used for guidance in the development of Emergency Operating Procedures (EOPs).
The PGP states that printed operator aids, including graphs, must be self-explanatory.
Contrary to the above, as of January 28, 1988, the licensee's E0Ps for Natural Circulation Cooldown required operators to use a graph that was not self-explanatory.
Several of the E0P steps directed the operator to maintain the Reactor Coolant System (RCS) temperature and pressure within the limits of Technical Specification 3.4.9.1, Figure 3.4-3 (cooldown limitation curve).
Figure 3.4-3 was not labelled as to which temperature and pressure instrumentation is intended to be used for comparison to the curve, nor is this information contained in the E0P steps.
These operator aids were not self-explanatory.
The E0Ps involved include:
19002-C, ES 0.2, Natural Circulation Cooldown, Rev. 3; 19003-1 ES 0.3, Natural Circulation Cooldown with Steam Void in Vessel (with RVLIS),
Rev. 2; and 19004-1, ES-0.4, Natural Circulation Cooldown with Steam Void in Vessel (without RVLIS), Rev. 2."
RESPONSE TO DEVIATION 50-424/88-07-01 Reason for the deviation:
The deviation occurred due to a failure to recognize the lack of specificity in the labeling of Technical Specification figure 3.4-3 used in preparation of the natural circulation cooldown E0Ps.
Corrective steos which have been taken and the results achieved:
(1) On April 8, 1988, the following procedures were revised to use RCS Cold Leg temperatures when referencing Technical Specification Cooldown Curves:
19002-C, Rev. 3 Emergency Operating Procedure:
ES-0.2 Natural Circulation Cooldown 0885m E-1 04/29/88 SL-4546

GeorgiaPower A ENCLOSURE (Continued)
NRC NOTICE OF DEVIATION 88-07-01 AND GPC RESPONSE 19003-C, Rev. 2 Emergency Operating Procedure:
ES-0.3 Natural Circulation Cooldown with Steam Void in Vessel (Hith RVLIS) 19004-C, Rev. 2, Emergency Operating Procedure:
ES-0.4 Natural Circulation Cooldown with Steam Void in Vessel (Hithout RVLIS)
(2) The uses of other referenced figures cited in the E0Ps were reviewed I
for possible needed revisions.
No revisions were required as a result of this review.
(3) A Licensing Document Change Request was initiated to revise the Technical Specifications (TS) to make the TS figures for cooldown more specific.
In addition, a notification was placed in the Required Reading Book which instructed plant operators to use the cold leg temperature when employing the Natural Circulation Cooldown E0Ps.
Corrective steos which will be taken to avoid further deviations:
The corrective actions discussed above are expected to preclude further 4
deviations.
[
Date when full comoliance will be achieved:
The corrective action is expected to be completed by November 1, 1988 contingent upon approval of the proposed Technical Specification revision by the NRC.
