Georgia Power (bupany hereb/ provides the following information in response to the violation cited in NRC I&E Report 50-321/84-41 and 50-366/84-41 dated December 5,
1984.
We albject violation was identified & ring the NRC inspection conc 11cted at Plant Hatch Units 1 and 2 by Mr. R. V. Crlenjak of yaar staff on September 21 - Notember 20, 1984.
VIGATION 1:
Technical Specification 6.8.1 realires that proce&res controlling the operations and maintenance of safety-related systems be established and inplemented.
Plant Procedure HNP-34, R11es for Performing Proceclares, realires verbatim compliance.
Contrary to the
- above, procedures were not properly established / implemented in thats a.
On October 6,
- 1984, while attenpting to perform presentive maintenance on Unit 1 residual heat renoval (RHR) service water punps (1E11-C001B and IEll-C001D),
plant personnel mistakenly disconnected the electrical motor leads for Unit 2's RHR service water punps (2 Ell-C001B and 2 Ell-C001D).
b.
Reactor water cleanup (RhDJ) system flow transmitter (2G31-N012, EIIS-CE) was inproperly installed claring coupletion of Design Charge Request (DCR)83-285 on December 21, 1983.
c.
%e keep-full system jockey puup discharge valves for Unit 2, train A core spray (CS) and RHR systems were improperly aligned.
%e inproper alignment (shit) rendered the keep-full system incapable of maintainirs the CS and RHR systems discharge lines full.
This is a Severity Letel IV violation (Ripplement I.D.2) Units 1 and 2.

IESPOtEE VIOLMPION las 3
a.
Admission or denial of alleged violation: Se violation occurred.
Reason for tbe violation:
%e disconnection of the motor leads for Unit 2's RHR system was the reallt of personnel error. The responsible 4
indivi&al checked the motor MPL mmber twice against the procedsre, hit did not realize that the MPL mmbers were different. Se re& ndant 'A' loop of RIESW remained operable..
t corrective steps which have been taken and the reaalts achieved:
Upon discovery, the actions reca2 ired by the Limiting condition for Operation and an eenipment clearance were initiated without delay.
Personnel reconnected and tested. the Unit 2 pings' motor leads per procedure M4P-6920, "Hi Potential Testing of Plant Eatipment".
The pings were returned to. service 61/2 hours after the leads were removed.
Se responsible personnel were counseled by their mapervisors with regard to the event.
A critione on the event was held with responsible personnel. The' responsible indivi&als held a briefing for the rest of the maintenance shop about the incident.
f Corrective steps which will be taken to avoid future violations:
Se above actions are mafficient to prevent recxtrrence.

- b.. Admission or ~ denial of alleged violation:
A violation of NRC regnirements occurred in.that the flow transmitter was incorrectly installed.
l Reason' for the violation:
Se incorrect installation of the RNCU &ng r
flow transmitter was the restit of personnel error. Sensing lines were incorrectly connected & ring coupletion of a Design Omnge Reglest (DCR 83-285).
The RNCU area tenperature detection system. (2G31-N600h-F) l.

Page Three IESPOtEE VIOWffION lb (contimed):
page 6 of the Inspection Report details. The responsible personnel were
_~
counseled by their aspervisors with respect to this incident. The RW0l!
system was demonstrated to be operable by satisfactorily performing the "RNCIJ-System-Differential Flow Instrument FTfsC", procedire HNP-2-3501.
Additionally, the "RNCU Alto Isolation ISrr", procedire ItiP-2-3504, was satisfactorily completed. A general presentation was glven to personnel stressing the req 2irements for proper connection of the sensing lines.
albsessent to this 1983 event, additional administrative controls have been implemented at Plant Hatch for the purpose of increasing management control of ' the DCR process.
Review of safety related maintenance work orders before and after work is being done by the Site Work Planning Group.
The a&ninistrative process for assignment and review, of fLanctional1 tests 'was' upgraded with the implementation of procedire 50AC-MIT01 on ally 30, 1984.
Corrective steps which will be taken to avoid future violations ' The above actions are sufficient to prevent recurrence.
Date when full coupliance was achieved: R111 coup 11ance was achieved on Jamary 17, 1984 when the RWC1J dany flow transmitter was returned to service.

c.
Admission or denial of alleged violation: The violation occurred.
Reasok for the violation:
The keep-full system jockey punp discharge valves for Unit 2, train
'A', CS and PHR systems were inproperly aligned as a res21t of personnel error daring the performarce of a airveillance procedare.
j Corrective staas which have been taken and the reallts achieved:
The.
jockey pump d;,sdarge valves were inusediately placed in their proper positions.
G and RHR presaire returned to normal.
The rea11 tant lowest system pressare was approximately 20 PSIG..
The systems were vented to verify that the discharge piping was full of water. The two
. personnel responsible for the incident were given written reprimands on October 12, 1984.
Additional counselling was given to other personnel for failure to recognize the' abnonnally low system presaires.-
In reference to your letter of November 28, 1984, you noted that the 4
corrective actions taken as a reaalt of violation 84-34-01 had not been adeonate to prevent the occurrence of violation 84-41-01c. We note that I

VIOLATION 2:.
10 TR 50.72(b) (2) (ii) req 2 ires notification within four hcurs of an Engineered Safety Feature actuation, as inplemented by plant proceclare ItiP-424, paragraph B.2.b.
Contrary to the above:
, a.
On September 8,1984, with Unit 2 operating at 1745 mwt, the MG inboard and outboard isolation valves sh2t due-to a high differential flow signal.
21s ESF actuation was not reported until September 26, 1984.
b.
On November 6, 1984, with Unit 1 in refueling mode and the core unloaded, an actuation of Group 2 primary containment isolation system (PCIS) and an actuation of the reactor protection systen (RPS) occ2rred.
'Ihese two ESF actuations were not reported until November 7, 1984.
His is a Severity Invel IV violation (Sapplement I.D.3) Unit 1 and 2.

Reason for the violation: Both of the instances of late reporting were the reanlt of misinterpretation of the realirements"for reporting ESF actuations..On September 8, 1984, personnel failed to. recognize.that clomare of the isolation valves sha21d be interpreted as meeting the reglirements of Standing Order 84-21 for " activation of an ESF actuation system."
On November 6,
- 1984, personnel made an incorrect interpretation that the ESF actuations need not be reported with no finel in the reactor vessel.
With the absence of fuel, neither system was
~regaired to bei~ operable.'
~
Correctise steps which have been taken and the rea11ts achieimd: Ihe reg 11 red.. reports were made without delay upon recognition., of reportability.
shift personnel were briefed by shift meetings regarding reanirements to report all unplanned ESF actuations.
In addition, personnel are being routinely reminded of the reatirements of the Standing Order.
Other unplanned ESF actuations have occurred since November 6, 1984, and have been reported as renaired.
Corrective steps which will be taken to atoid future violations:
The abote actions are asfficient to prevent recurrence.
Date when full conpliance was achieved: Mill conpliance was achieved on November 7,
1984, when all outstanding urplanned ESF actuations were reported.
