~u C-'3 HUTQH ENGINEER IHG DISCREPANCIES TO BE CORRECTED PRIOR TO ISSUANCE OF AN OPERATING LICENSE This section contains a description of those discrepancies which must be corrected prior to issuance of an operating license.

Following each discrepancy is a statement of the Florida Power and Light Company's (FPL) commitment for corrective action.

A. 1.0 CONTROL ROON WORKSPACE I IHDING h.1.1 There are two large floor obstructions in the form of thick plywood sheets attached to the floor One is between the control console mockups and one is near the restroom location.

(l.2)"

RESPONSE

'I a gi 2

FINDING A.1.2 The plywood sheets referenced in the above finding are presently covering two blockouts which will.be used as control cable routine paths.

The blockout located between the control console mockups will be covered by the operator's work desk and will not provide a

traffic interference problem.

The second blockout located near the restroom was provided for the positioning of the auxiliary control panel and will not provide any traffic flow restrictions.

Presently a review is being conducted for relocating the auxiliary control panel.

If the panel is relocated, then the subject blockout will be filled thus eliminating the IrippIng hazard.

The temporary phone attached to Panel 202 has a long cord which presents a tripping hazard in an operator pathway.

It was noticed that phone cords in Unit 1 presented a similar tripping hazard.

(1 3)

RESPONSE

lIHDIHG The temporary phones'will be removed and the permanent communication system will be installed prior to issuance of an operating license thus eliminating the subject tripping hazard.

A. 1.3 There are no provisions for key storage and no procedures for key access control for keys used in the Control Room and for keys used at the Remote

.hutdown Panel.

(li6)

'Throughout the report the use of parentheses, such as (1.4), refers to the

, section and finding +umber used in the HFEB Control Room Design Review/Audit report, dated September 10, 1981.

Part A

RESPOHSE F IUDIHG Key storage will be provided as well as the necessary key access control procedures for those keys used in the Control Room and Remote Shutdown Panel prior to fuel load.

The Remote Shutdown Panel SIS block keys will be maintained at RAB control access point.

A.l. 4 All of the panels had controls which were less than 3 inches from the front edge of the benchboard.

The benchboard hardrails had not been installed at Unit 2 at the time of the review.

It was noted that the Unit 1 benchboard rails obscure the view of many controls and displays from the operator console.

(1. 10)

RESPONSE

FINDING The St. Lucie Unit Ho.

2 handrails will be installed at a lower position on the subject benchboards'o as to not obscure the view of those controls and displays, which are located on the front edge of the benchboards,

.rom the operator console.

The handrails will be installed prior to issuance of an operating license.

A.1.5 The normal lighting level in the backpanel areas was inadequate.

The level at Backpanel 206 was 5.5 ft-candles, which is even less than the minimum requirement of 10 ft-candles for a passageway.

(1.12)

RESPONSE

FINDING Incident light levels will be reviewed and brought up to acceptable levels as outlined in HUREG-0700.

fhis item will be scheduled for implementation prior to issuance of an operating license.

A. 1.6 Glare was a problem throughout the control room.

At the time of the

review, no di ffusing grid had been placed over the fluorescent lighting as has been done in Unit 1.

The glare in Unit 2 had a varying impact from one instrument to the next, with the worst case being nearly total obscuration of displayed informaton.

(1. 13)

RESPOHSE A re-evaluation of the glare problem will be performed after the diffusing grid has Seen installed.

Those items. then still found to.

have glare problems will have suitable backfits implemented prior to issuance of an operating license.

(1.14)

RESPONSE

FINDING There will be a direct means of testing the operability of the.

control room emergency lighting system prior to issuance of an operating license.

A. 1.8 The emergency lighting illumination levels were too low for accurate reading of panel di'splays and labels.

Readings varied from 22.6 to 1.9 ft-candles.

The Panel 204 reading was 8.3 ft-candles.

(1.15)

RESPONSE

FINDING Lighting diffusers were not installed at the time of the audit.

Upon installation, incident light readings will be taken.

Based on data from the above, additional lights, as required, will be installed to bring emergency control room illumination to acceptable levels 'as outlined in HUREG-0700.

This item will be scheduled for implementation prior to issuance of an operating license.

A. 1.9 The two separate Control Transfer Panels for the Remote Shutdown Panel are not provided with, security devices to prevent unauthorized transfer of control between the Control Room and the Remote Shutdown Panel.

(1. 16)

RESPONSE

The Remote Control Transfer Panels will have a security seal for security purposes.

Operations of any control transfer switch is annunciated in the control room.

These provisions will be implemented prior to issuance of an operating license.

RESPONSE

The Sequence oT Events Recorder is currently employed to print out sequence of events of Reactor Trip signals.

The initiating signal is printed as part of this sequence.

Therefore, the SER is the main means of identifying the cause of the trip.

This item will be addressed as part of the long-term design review and reported on in accordance with NUREG-0700.

FINDING 8.3.2 On all annunciator panels, the only indication that an annunciated condition has been cleared is the extinguishment of the light.

(3.7)

RESPONSE

F INDIHG The present annunciator system is consistent with Florida Power and Light's standard design philosophy.

Clearing of an annunciator is indicative of a back to normal condition which is a safe condition and requires no operator action.

It is felt that having the operator responsible for acknowledging return to normal conditions during a plant transient or other evolution requiring his attention could impede his judgement and affect his response time in reacting to a given situation.

This item will be reviewed as part of.the long-term design review and reported on in accordance with NUREG-0700.
