ATTAC3M!NP 1 Muspansc'to Weakness 50-458/9006-01 i<rmnCE Letter - S. J. Collins letter to J. C. Deddens, dated April 5, 199 DESCRIPTION a

During the annual emergency response' exercise, the NRC inspection team noted that the control rom failed to emplete notifice.tions to _ state and 1 local authorities within 15 minutes when both the notice of unusual event !

(NOUE) and the site area emergency (SAE) classifications were declare During the exercise a- NOUE was declared at 8:31 However, i notifications were not empleted until 8:59 a.m.,_ which was 28 minutes after the declaratio An SAE was declared at 10:22 a.m. However, notification of the last parish was empleted at 10:46 a.m,, which was 24

'

minutes after the declaratio i GUIE STATES [7TILITIES COMPANY'S RESPONSE -i The delay in notifications of offsite authorities arose because of two separate problems. The first problem was in delivery of the ~tDUE message and is attributed to the software of the simulator cmputer being different frm that of the control rom cmputer. This difference created operator difficulties which caused the delav in the tCUE notification. The delav in the SAE noti.fication was caused by one of the parishes not receiving the notification message when transmitted. The message was read to that parish over the batline when the message verification was performe We software in the simulator hr been changed to duplicate the software in the control rom. Further anticipated software changes include:

- Svnchronizing the emputer clock on all stations to update to the correct tim Removing all default values and leaving those spaces to be filled

'in rathar than having to change the each time a message is sen Once the time, date, new or unchanged, information is entered, it would remain until changed by the operato Changing the logic for making location addresses in the re-transmission of message Constructi m a short form notification message for notifying the offsite aathorities of emergency classification changes in order to meet the 15 minute criteri Changing the next transmission clock to update properly based on initial, escalation, or followup message tim *

1. . ; 7 .

"

'

The problem with sme stations not receiving a message because the remote

. systern is 'not receiving has also been examined. A small voltage dip can

- cause the. printer to drop off line,' but is not enough to drop the system

-

off line. As a result, when a message is transmitted, the printer will not react and print the. message. A test station has been used to evaluate an-uninterruptible power supply (UPS) for the micro-processor. '1he UPS keeps

.

this . dip frm dropping the printer off-line. A UPS will be placed at al locations of the Emergency, State and Parish (ESP) emputer printers .in the offsite agencie ~

Training time on the ESP cmputer will be increased by the following:

- When the Operation crews are attending off-crew training every'6 '

weeks, more time will be devoted to the ccrmunicators on the ESP ccrpute Also, - during simulator time, when a cmmunicator is'

available and scenarios warrant, the message notifications will be constructed and printe On the backshift ' in the control an, the comunicators will be asked to build a message and print it. .This message will be reviewed and sent back to the individual. with ccmnents on Correctnes The UPS installations and training improveme nts will be empleted by Januarv 9, 199 .

ATDONNP 2 3 1.,mii.e to Weakness 50-458/9006-02 REFERENCE letter - S. J. Collins letter to J. C. Deddens, dated April 5, 1990 DESCRIPTION During the annual emergency responso exercise, the NRC inspection team noted that a slte area mergency (SAE) was announced in the TSC at 10:22 However, site evacuation announcements over the plant public address system and the ac4M evacuation of site personnel did' not begin until 10:45 a.m., whlen was 23 minutes late In addition, personnel accountability after the site evacuation did not take place within_ the 30 minutes established by NUREG 0654, section J.5 and by the RBS Dnergency Plan. Accountability whs not established until about I hour after SAE declaratio '!

GULF STATES UTILITIES COMPANY'S RESPONSE The delay in performing personnel accountability was caused by tm factor The first was the delay in announcinq the protected area evacuation for 23 /

_

minutes fran the time of the SAE declaration. %is delay was attributed to a comunications misunderstanding between the Emergency Director (ED) and Security Coordinator (SC). The ED is directed by EIP-2-026, " Evacuation",

Revision 3, Section 4.2.1, to coordinate the evacuation with the SC and the Radiation Protection Coordinator (RPC) prior to the announcement. Wis was done and the ED stated he was going to- make the- announcement but then became involved with other matters. The announcement was made when the ED was reminded by the S We accountability delay was also caused- by the security corputer not -

identifying those personnel in the technical support center (TSC) and the Security officers. Also, Security was not aware that there mre personnel I who staved in the protected area because of plant wor We importance of making the protected area evacuation announcement has been discussed with all parties involved, and is stressed in training and 1 drill briefing :

The TSC card readers have been reprogranmed to indicate Dnergency Facility ,

Accountability Zone #6 (the TSC). Now when accountability is performed, I-personnel in the TSC will be shown as in the TSC and not just as being in the protected are The on-duty Security Shift Supenrisor has been instructed to line through all on-duty security personnel reflected on the conputerlud accountability roster prior to sending it to the TS Also, ,

when accountability drills are conducted, a list of those people who must '

'

remain in the protected area due to critical plant work will be provided to I the SC in the TSC. (We OSC has recently been noved fran the 3rd floor to j the 2nd floor of the Services Building with the exception of the card reader. The accountability of persons within the OSC will be provided by a -l security of#icer to the SC in the TSC. %e proiected date for card reader installation in the new OSC is January 23, 1991.)
