The purpose of this letter is to provide the information required to close Limerick License Condition 2.C.8(a) part 2, as contained in the reference 1 letter, and to complete the information submitted in our reference 2 letter.
LIMERICK LICENSE CONDITIONS 2.C. (8) (a) DETAILED CONTROL ROOM DESIGN REVIEW Part 2: Control Room Survey The licensee shall satisfactorily complete the control room survey, evaluate all human engineerina discrepancies defined by the survey, including those ' defined by the staff's audit team during the In-Progress Audit, and correct human engineering
. discrepancies which have been categorized as Priority 1 (High Safety Significance) prior to operation at a power level greater than five percent of rated power.
The results from the effort are to be documented in an addendum to the Final Report and submitted for staff review.

Response
F PDR
,y The control' room survey is complete with the exception of the review of the Safety Parameter Display System (SPDS) which is not operational at this time. The delay in the completion of this part of the survey is acceptable for the following reasons:
n
1
. 1)
The SPDS itself will not be operable until its validation and testing program is complete.
2)
General Electric, the system designer of the SPDS, has hired a human factors consultant to assist in the man-machine interface development. The NRC has performed a Design Verification Audit of the General Electric design effort and reported the results of their review in Supplement No. 3 of the Limerick SER. (Section 18.2.5) 3)
During the Limerick CRDR validation effort a hardcopy of the SPDS displays were used to verify their coordination with the CRDR.
Based on the above, there is a very low probability that the completion of the SPDS survey will identify any priority 1 or priority 2 human engineering discrepancies (HEDs).
A human factors survey of the SPDS will be performed prior to the turnover of the SPC3 to Limerick for use. by the control room operators.
This survey will use the applicable portions of the BWR Owners' Group Control Room Survey Checklist. The portions of the survey used will include a review of the SPDS keyboard and CRT displays, (Computer console sections.-D1 & SDl, Computer capability sectior.s-D2 & SD2, and Computer CRT sections-D3 & SD3 of the BWR Owners' Group Checklist).
. All the other items that are part of this License condition (i.e., all HEDs assessed for safety impact and/or corrected prior to exceeding 5% power) have been completed.
All HEDsi identified have been corrected or assessed with no new priority 1 HEDs.
This includes the 8 NRC Audit Team HEDs which were discussed in the reference 2 letter and is further discussed below in the response to item 1 of the request for additional information.
REQUEST FOR ADDITION INFORMATION Item #1 - Control Room Survey The licensee shall assess and report on the results of the essessment of all of the HEDs defined by the NRC Audit Team during the In-Progress Audit.
gsponse:
The CRDR review team has assessed the 8 open NRC Audit Team HEDs (see reference 2).
This assessment identified no priority 1 (high safety significance) HEDs and only one priority 2 (low safety significance) !!ED. - This priority 2 HED ' (NPl-01) was identified during construction and was corrected prior to system turnover.
The remaining seven.HEDs were all assessed as priority 4 (no safety significance or reliability concern).
F L
t l
-. The HED. assessment ' sheets for these 8 HEDs are enclosed in
' attachment #1.
-Item #3 - Assessment of HED's, Re-assessment of HED SPV-07 I.
The licensee shall report results on the reassessment of HED SPV-07.
j
Response
l L
The correction.of HED SPV-07 (T-200 Series Procedures) has been l
completed.. All T-200 series procedures have been revised and approved by-the Plant Operations Review Committee (PORC) to properly: reflect the enhanced hierarchical labeled control room.
Item #5: Coordination of NUREG-0737 Supplement 1 items.
l During the reference 3 teleconference the NRC requested f-additional information on the coordination of the NUREG-0737 I
Supplement 1 items. These include the following:
.l.
. Emergency Operating Procedures 2.
Accident Monitoring Instrumentation - R.G.-l.97 3.-
Safety Parameter Display System (SPDS)
-4.
Emergency Response Facilities 5.
Detailed Control Room Design Review
= Response:
During the final validation' effort the coordination of the above i
systems / facilities was completed. 'The actual' validation was a l
. walkthrough/talkthrough -. of the Emergency Operating Procedures j
using hardcopy' displays for SPDS on'a full-scale enhanced mockup of the Limerick unit #1 control room. This walkthrough/talkthrough l
identified areas where a. control room operator would require p
. comununicationc-with the Emergency Response. Facilities-and the i
operator.discribed what 1 control room consnunications equipment would be utilized to complete this task. In addition HED SIl-06, l
(Reg. Guide 1.97* instrument enhancements) was implemented on the full scale mockup prior to this walkthrough/talkthrough.
The-operators could quickly identify..these ' environmentally qualified l
instruments during these walkthrough/talkthroughs.
l I
This final validation was an effective method of' coordinating the
~
i
' integration of the NUREG-0737. Supplement 1 ' items..
.Any I
. discrepancies identified during these' walkthrough/talkthroughs were ~ classified as. a ~HED and assessed in the Final ~ Report l
Supplement No.1-. (reference 4,page 8 and Appendix A). -
