Subject:

Quad Cities Station Units 1 & 2 Response to Request for Additional Information Generic Letter No. 83-28 NRC Docket Nos. 50-254/265 Reference (a):

April 23, 1985 D. B. Vassallo letter to D. L. Farrar - Quad Cities

Dear Mr. Denton:

References (a) requested additional information on Generic Letter 83-28 items 2.1, 2.2.2 and 4.3.5.

Attached are responses to that request.

Please address any questions that you or your staff may have concerning our response to this office.

One (1) signed original with Attachment and forty copies are enclosed for your use.

Quad Cities Station Units 1 and 2 Item 2.1.

Licensee needs to submit detailed information describing his vendor interface program for reactor trip system components Information supplied should state how the program assures that vendor technical information is kept complete, current and controlled throughout the life of the plant and should also indicate how the program will be implemented at Quad Cities, Unit 1 and 2.

Response

Attached is a copy of the Quad Cities procedure, QAP 1800-9, which is being implemented in response to Generic Letter 83-28.

Information pertaining to reactor trip system components will be handled according to this procedure.

Item 2.2.2 Licensee needs to present his evaluation of the NUTAC program and describe how it will be implemented at Quad Cities, Units 1 and 2.

The staff found the NUTAC program fails to address the concern about establishing and maintaining an interface between all vendors of safety-related equipment and the utility Accordingly the licensee will need to supplement his response to address this concern.

This additional information should describe how current procedures will be modified and new ones initiated to meet each element of item 2.2.2 concern.

Response

i CECO has been informed through INPO that the March, 1984 NUTAC document is acceptable to the NRC.

Therefore, this letter does no expand on previous responses.

CECO used the NUTAC report in developing the Nuclear Stations Division Directive and the Quad Cities Station procedures.

l Item 4.5.3 j

The staff finds that modifications are not required to permit I

on-line testing of the backup scram valves.

However, the staff concludes that testing of the backup scram valves (including l

initiating circuitry) at a refueling outage frequency, in lieu of on-line testing, is appropriate and should be included in the Technical Specification surveillance requirements.

The licensee needs to address this conclusion.

l

9

! Regarding the scram pilot valves (including all initiating circuitry), the licensee needs to provide the results of a review of existing or proposed intervals for on-line testing considering the concerns o f sub-items 4.5.3.1 to 4.5.3.5 o f the generic letter.

The response shall show how these intervals result in high reactor trip system availability and present proposed Technical Specification changes for staff review.

The staff has just received the BWR Owners Group response to Item 4.5.3 (NEDC-30844).

If tne licensee intends to formally endorse the Owners Group response, the licensee should delay his plant-specific response to Item 4.5.3 until after the staff completes its review of the Owners Group response.

Response

The BWR Owners Group response to Item 4.5.3 is embodied in report NEDC-30844. Since this study was based on a standard RPS which is not identical to_the Quad Cities system, we can not formally endorse the study of this time.

We are proceeding with a review of the system differences to determine that the conclusions of the generic study remain applicable to Quad Cities.

Therefore, we are using NEDC-30844 as the basis for our response, but do not know at this time what further stipulations are required.

We anticipate that results from the site specific review will be available by August 1, 1985 and that we will be able to formally endorse NEOC-30844 at that time.

CONTROL OF VENDOR EQUIPMENT TECHNICAL INFORMATION A.

PURPOSE To establish control of vendor equipment technical information (VETI) used to perform work on safety-related and certain non-safety-related equipment.

B.

REFERENCES 1.

Nuclear Station Division Directive MO-2, " Control of Vendor Equipment Technical Information."

2.

Institute of Nuclear Power Operations Good Practice MA-304, " Control of Vendor Manuals."

3.

Institute of Nuclear Power Operations84-010 (NUTAC),

" Vendor Equipment Technical Information Program."

C.

PROCEDURE 1.

General use of controlled VETI documents.

a.

Controlled VETI can be used for procedure development or referenced as part of a procedure or work package.

b.

Excerpts or portions of controlled VETI may be issued in accordance with station procedure QDM-ll, Drawing and VETI Control for Work Requests, Procedures, and Plant Modifications.

c.

If a controlled VETI document is lost or destroyed, the Central File shall be notified.

If a VETI document that was reported lost is found, it shall be returned to Central File for disposition.

l 2.

VETI will be controlled:

l a.

At the request of a Department Head.

l b.

If a Station procedure or work request is safety-related, or non-safety-related but important for the safe operation of the plant as determined by the cognizant Department Head, and must be performed with reference to the VETI.

(1)

Determine that the appropriate VETI appears in the reference section of the Station procedure.

If not, identify the appropriate VETI and initiate a Station procedure change request per QAP 1100-4 to reflect the correct VETI (for Station procedure only).

L

i l

4 (2)

Add the VETI to the VETI control program in accordance with step C.S.,

if the referenced VETI is not already controlled.

(3)

Any correction or additions made to the controlled VETI while being used should be performed in accordance with step C.5.

3.

Sources of vendor documents.

a.

Information notices.

(1)

Service information letters (SIL's).

(2)

Turbine information letters (TIL's).

(3)

General Electric Service Advices.

(4)

NRC Information Notices.

(5)

The reviewer will review the VETI document using the checklists QAP 1800-S1, part 2 and QAP 1800-S2.

Based upon the available information and knowledge, the reviewer will:

(1)

Determine if the VETI is applicable to the equipment installed in the plant.

(2)

Determine if the VETI reflects the "as built" condition of the applicable equipment as installed in the plant.

(3)

Determine if there are significant errors or missing information.

Make all necessary corrections.

(4)

Determine if this VETI can cause or contribute to the degradation or failure of associated equipment.

(5)

Obtain vendor concurrence if discrepancies regarding technical content exist or if additional information is necessary.

If the concurrence of vendor cannot be obtained, the reason for lack of concurrence shall be documented.

(6)

Identify on QAP 1800-S2 the equipment piece number (EPN) or the model number of equipment that is applicable to this VETI.

The Department Head will complete part 3 of QAP 1800-S1.

d.

The VETI and all supporting checklists shall be forwarded to the Station Vendor Equipment Technical Information Coordinator (SVETIC).

(3)

Complete / update QAP 1800-S3.
