N OF UPDATED INFDRRATION ON DCRDR N NUCLEAR PLANT, UNITS 1 AND 2-This letter is being written to provide you with-an update on the 1 status of the implementation of' resolutions to' Human Engi"eering

' Discrepancies-(HEDs)-documented during the Detailed Control Room

Design Review (DCROR)fperformed at Point Beach Nuclear Plant (PBNP).

fan HED resolution.' schedule,'along with all of the UEDs, was submitted'

_ twith thelPBNPiDCRDR' Summary Report on March 31, 1987'. The resolution

? - schedule;and-selected HEDs were revised and submitted'in response-to the NRC audit'of the Point 4 Beach DCRDR on March-29, 1988 (VPNPD-88-186 and NRC-88,033). This submittal provides information on the status of-

.the implementation'of HED.' resolutions and includesa revised resolu-1, tion schedule; Also being provided is information on HED resolutions that:have changed since-the last submittal;in 1988.

The: attached information has been organize'd by HED resolution tcategory.; All HEDs were categorized by the~ general form of.their

. resolution and the resolution schedule was then based on these

~

categories.. The attached Table 1 provides a summary.of the status of

,

each of the different categories, based on the total number of HEDs in

< :each category. Although. dealing with riumbers of HEDs does not really give a: c] ear picture of the amount of work completed because (1) the l scope.of a HED can vary'significancly, and (2) the same discrepancy

'may be repeated ~on several HEDs, the table does give an indication

'that' substantial work'has been accomplished in each category.

. Detailed information regarding the resolution status in each category

_- is provided in Ittachment A.

[ ' STATUS OF DCRDR HED RESOLUTIONS POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 n

y-Lighting The basic: intent of the Lighting HEDs was-to document any deficiencies (based on NUREG-0700) -in normal and/or emergency-

' lighting levels-at= control room work areas. The survey performed during the initial review indicated that lighting-levels were below NUREG-0700 levels in-just about all work areas. An 4 additional survey' performed just prior to submission of the DCRDR Summary Report indicated that; acceptable levels could be attained ,

.in all work areas by insertion of additional lighting tubes in existing fixtures. This led us to: state in the Summary Report that wi expected to have all Lighting HEDs resolved by the end of 1988.

A followup survey was performed by our human factors consultant in January 1988 to ensure that the ne lighting arrangement satisfied NUREG-0700. Levels were acceptable in all locations but in front of the Auxiliary Safety Instrumentation Panels (ASIPS). This new arrangement seemed to be acceptable to all of the operators. In July 1989, an additional survey was performed by WE personnel. The results of this survey showed the lighting-levels to.be.slightly below NUREG-0700 minimum levels, although we are fairly certain that the lighting arrangement did not change. Aftar this latest survey, lighting levels were increased to bring them above NUREG-0700 minimum levels. A two-week trial of this arrangement was judged by the operators to cause excess glare, eye fatigue, and headaches. ,

As a result of the operator feedback, we are going to keep the normal lighting levels as:they are-now, with the exception of the areas in front of the ASIPs.' We are planning to install addi-tional fixtures in front of the ASIPs,-which was an unanticipated addition to DCRDR workload, by the end of 1991. In addition, we

' intend to power a string of fixtures from the second emergency diesel generator (one string is already powered from an EDG) to improve emergency lighting levels. We expect to complete this modification by the end of 1991 as well.

Computer Eleven of the 14 computer HEDs have been resolved. Further action will be taken on the following HEDs:

o HED 786: requires additional software changes, which are scheduled for completion in early 1990.

final.ized. We-expect this to be completed by the end of 1990..

o HED 794: requires hardware changes, which will be handled with the changeout-of computer consoles in 1991.

Training  ;

'l Thirty-one HEDs were categorized as Training. Twenty-four have-been' satisfactorily resolved. Of the remaining seven.HEDs:

o' HED 655 should have been categorized as Procedural Change.

.It will be addressed with the other remaining Procedural Change HEDs.

o. .The need for or scope of training for six HEDs has not been resolved to the satisfaction of the DCRDR team. These HEDs are. expected to be fully resolved by December 1990. ,

i Procedural Change <

A total of 112 HEDs were categorized as Procedural Change.

Resolutions to 101 HEDs have been implemented satisfactorily.

However, the remaining HEDs were either not completely-resolved by the' associated procedure changes, or require the results of an ,

electrical loading study, which has been delayed into 1990. We expect that the rest of the HED resolutions will be implemented by December 1990.

v Enhancement Prior to this submittal, there'were 34 HEDs in the Enhancement

, category. -After the Summary Report was submitted, the following changes were made:

o The resolution of HED 339 was changed from enhancing the existing C67 ventilation control panel to fabricating a new

. panel. Fabrication of this new: panel, which was an unanti-cipated addition to DCRDR workload, . will not be able to be completed until the end of 1991.

o -HEDs 10, 563, and 766 would be more appropriately categor- I

-ized as Meter Face Modification HEDs and will be handled as  !

'such, with completion expected in 1991. l Of the remaining 30 HEDs, nine have not been resolved. Of these nine, eight address the control board mimics. Resolution of these HEDs has been delayed because of the PBNP simulator, which is currently under construction. Because the simulator vendor could not match some of the existing mimic colors, it was decided that some new colors would be used and the existing control room mimics would be totally replaced. Resolution of mimic HEDs will be handled along with mimic replacement in 1990. The ninth 5

Annunciators-E .As1of March 29, 1988, the date of our previous submittal, there t were130 HEDs in the Annunciator' category. Since then, the following changes have.been made: l o The" resolution and category of HED 229 were changed after it  !

was decided that no further action was necessary'(a copy of

~

4 ,

HED'229 is-included in Appendix-1 to this attachment). 't I

o .The categories of HEDs 293,'327, and 353 were changed to ,

Control' Room Modifications because the resolutions of the e

HEDs primarily concern plant modification such as control circuitry changes,: cable. pulls, etc., with the associated changes in the annunciator tiles being relatively minor  ;

parts-of the overall modifications.

Of the' remaining 26 HEDs, eight will not be. resolved _by the end. -

of 1989. All'eight of these HEDs are to be resolved by the  :

replacement of'the existing annunciator tiles. Replacement has been delayed because of several' revisions to the annunciator tile legends data base and an additional delay in annunciator tile fabrication. We expect to have the new tiles in place by

, December 1990.

. Instrument Air Modification All seven' Instrument Air HEDs_were to have been addressed by MR 85-243, a modification request initiated in 1985 and expected to be. completed by the end of this' year. This modification was >

completed on schedule, so these HEDs are resolved.

. Labeling Eighty-six~HEDs were categorized as Labeling.- Resolutions to 50

=HEDs have been or will be' implemented by'the end of 1989 with the essential' completion of thefcontrol room' relabeling project. The project included a review of the contents of all component labels to ensure the use of a consistent format, accurate and consistent nomenclature, and standard abbreviations. Essentially all component labels'(approximately 1500) were or will be replaced by the end of the year. A' hierarchical labeling scheme was also installed. Regarding the'HEDs whose resolutions have not yet been implemented:

o_ Nine HEDs address meter face legends and are more properly categorized as Meter Face modifications. These will be resolved with the implementation of new meter faces by 1991.

o Seven HEDs address mimic labeling and will be resolved when new mimics are installed in 1990.

' Finalizing of the new meter face legends and scale designs took longer than; originally anticipated. Difficulties were then encountered 1 1n finding a-legend type size that was satisfactory s- to'WE and that was'available from the meter facesmanufacturer.

. .To date, we-have obtained meter faces that are not all suitable for installation. Higher priority work has also precluded personnel from developing installation' procedures and, in some L" cases, instrument loop modification or recalibration procedures, that are necessary for this work. For these reasons, resolution .

of meter. face HEDs has been delayed until-1991..

Communication

. Twelve HEDs.were categorized as Communication. Resolutions to two HEDs have already been-implemented, and we expect all remaining resolutions will be implemented by the.end of 1990, as  !

originally scheduled. i New-Instrumentation Forty-three HEDs were categorized as New Instrumentation.

Resolutions to nine HEDs have already been implemented, and we still expect to meet our proposed schedule for the remaining 34 HEDs.

Control Modification i Forty-one HEDs were categorized as Control Modification.

Resolutions to 25 HEDs have already been implemented, and we  !

expect all remaining resolutions will be implemented by the end .

of 1990, as originally expected.
