Docket No. 50-278 U.S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555 I

SUBJECT:

Progress Report for Implementation of Control Room Enhancements Pursuant to NUREG-0737 Peach Bottom Atomic Power Station, Unit 3

REFERENCE:

1) Letter, S. L. Daltroff, PECo, to D. R. Muller, USNRC, dated February 26, 1986;

Subject:

Control Room Design Review L

2) Letter, E. P. Fogarty, PECo to USNRC

)

dated June 30, 1989 In the reference 1 letter, which transmitted.the Control Room Design Review (CRDR) Report, we stated that a progress report on the implementation of the control room enhancements would be submitted-to the NRC within two months following completion of the next refueling outage for Peach Bottom Units 2 and 3.

This letter E,

provides the status of the control room enhancements as of the end D

. of the 7th refueling outage for Unit 3.

Reference 2 letter submitted the progress report as of the end of the 7th refueling outageJfor Unit 2.

\\_1 4;

The submittal of this report was delayed to allow for an independent verification of the control room enhancements status.

We regret any inconvenience this delay may have caused.

In the CRDR Report, 262 Human Engineering Discrepancies

^

(HEDs) were identified.

Each HED was assigned a priority with respect to safety using a significance scale of 1 to 6, indicating L

the overall111kelihood of the HED to cause operator error.

Three (3) HEDs ware assigned' dual priorities.

The HED priority categories and numbers of HEDn aa=lgned to each were:

Document Contrcl Deck Fcbrunry 15, 1990 Page 2 i

l Priority Number of Unit 3 UEDs Identified Resolved 1

High Safety Significance 10 10 2

Low Safety Significance 44 36 3

Operational Reliability 26 14

[

4 No Significant Improvement 94 66 5

Previously Corrected 52 NA 6

Not A Discrepancy 39 NA The subject, schedule, and status of each identified Priority 1 and 2 HED are provided in Tables 1 and 2 of Attachment 1 to this letter.

The status is presented as the actual outage the HED was resolved or the forecasted (F) outage during which the HED will be resolved.

In summary, the corrective actions for all the Priority 1 HEDs scheduled for the 7th and 8th refueling outages have been completed for Unit 3.

The corrective actions for 36 Priority 2 HEDs were also completed during the 7th refueling outage.

The remaining Priority 2 HEDs, D5-09, 13-07, TAl-01, TAl-06, TAl-16, SPl-02, VW-11 and VW-12 will be resolved during the 8th refueling i

outage as originally scheduled or as indicated in Note 1 for Table 2 of Attachment 1.

During the implementation of the Priority 1 and 2 HEDs, the corrective actions for many Priority 3 and 4 HEDs were completed.

The resolved Priority 3 and 4 HEDs are listed in Table 3 of.

"Yes" appears in the "HED REV" column of Tables 1 and 2 If corrective actions changed.

The corrective actions for one dual Priority 1/2 HED and four Priority 2 HEDs have been revised, and one HED has been cancelled (no action required).

The HED Assessment revisions are provided in Attachment 2.

PEco will update the NRC on the status of the control room enhancements annually as committed to in the Reference 1 letter.

Should you have any questions regarding this progress report, please do not hesitate to contact us.

Annunciators ID or Number:

N/A DESCRIPTION:

No special cue is available to an operator (e.g a slower blink rate) to indicate when an alarm input clears. The operator must determine on his own, that the alarm has cleared.

RESOLUTION:

(Sched:

None

)

The previous resolution of this HED required the position on of the internal: annunciator slide switch to be engraved on the cnnunciator window. Alarm cards were to be revised to-indicate the required setting. Guidelines for setting switches were to r

be provided. This resolution is revised. The slide switch position will not be engraved on the annunciator windows. Revised i

cnnunciator procedures have been prepared to show the required position of the slide sut:ches.

i TRAINING REQUIREMENTS:

Trair, operators in system for required settings.

-PROCEDURE REQUIREMENTS:

Revised annunciator window setting procedure now in place l-REASON FOR REVISION:

The desire for additional controls has led to generation of a station

.. annunciator log / procedure in which the switch settings nre controlled.

Tha oparating phiinanphy in r.n require aggreamive fal.1nwup nn alarma,,--

Further review shows that the originally conceived engravings would be confusing.

MITIGATING CONSIDERATIONS:

Annunciator alarms exist for Reactor Low Low Level and Drywell liigh Pressure, both initiating conditions for HPCI.

Item:

Ref*

Source: TA IDEFTIFICATION:

Panel: 20C209L Component: ADS NITROGEN HI/ LOW Pressure ID or Number: T-101 RC/P, Step 9b DE3CRIPTION:

The SRV controls are on Panel 20C03(2). To operate the SRVs, instrument N2 must be available. The absence of instrument N2 is announced by an alarm over Panel 20C09 approximately 28 feet away i

in the same plane.

(Deliberate Action)

RESOLUTION:

(Gehed: 8th Refuel

)

(1) The original resolution of this HED was to color the alarm window amber to alert operators to take immediate action.

i (2) The revised resolution is to move the alarm window to an annuciator associated with Panel 20C03(2).

TRAINING REQUIREMENTS:

Train operators in new annunciator window location PROCEDURE REQUIREMENTS:

Revise procedures to include new annuciator window location.

REASON FOR REVISION:

Recent modifications have added spare annunciator windows which were not available when this HED was orignally written.
