I ATTACHMENT NRC Reauest:
Item 2.1 (Part 1) - Incomplete.
A listing of RTS components reviewed, due 10/1/84, has not been received. A specific statement confirming that these components (RTS) are identified as safety-related on documents, procedures, drawings and information handling systems is needed.
Response
The District's October 5, 1984 submittal (RJR 84-441) updated the schedule for completing our RTS component review. Our new schedule indicated that this review would be completed by February 1, 1985.
We have completed this review and the components listed are identified as e
safety related (Class 1) on the Master Equipment List (MEL). The MEL is the o
QA list for equipment / components. The handling of components in documents, procedures, drawings and _information handling systems is based on the MEL classification of the component. As discussed in our November 4,1983 submittal, Item 2.2, the Maintenance Information Management System (MIMS),
which includes the MEL, identifies the procedures, drawings, and documents for components and controls all work on the components.
In previous conversation with members of your staff, the RTS listing is not required to complete your review of this item.
Your staf f also agreed that our original submittal did not commit to provide this list.
NRC Request:
Item 2.1 (part 2) - Incomplete Licensee should describe his program for periodically contacting vendors to ensure that all vendor technical information is being received, how maintenance infornation is developed for components whose vendors are no longer available, how maintenance and testing procedures are revised to incorporate up-to-date information, and how the performance of these procedures is controlled.
Response
As stated in our November 4, 1983 submittal (RJR 83-725) B&W was the supplier for the RTS components. The B&WOG tasked B&W to provide a list of RTS safety related components and the most current vendor information. The District has completed its review of this information and has updated the MEL and vendor library based on this review.
The District considers that these actions complete the requirements of item 2.1 and that the programs of item 2.2 will be relied upon for maintenance of current vendor information.

Response
The corrective action-to be taken.is unique depending on the results of findings of a. specific audit. The requirements for ensuring that adequate-corrective action is taken is discussed below.-
-s sQuality. Assurance. Procedure QAP.19 establishes and defines the program for
~
= auditing the: operation, maintenance, repair and modification of Rancho Seco. -The procedure requires prompt corrective action and followup audits to determine.the adeq'uacy andl effectiveness of the corrective actions taken.
. Quality Control Instruction QCI.2 provides the instructions-for the audit program. sThe audited group is responsible for determining corrective action to be taken to resolve any nonconformances identified by QA audits. QA and the Management Safety Review Committee (MSRC) followup is: required to ensure lthat prompt corrective action'is made.and-that the resolution or corrective action is acceptable.
E Copies.of QAP.19 and QCI.2 are attached for your infonaation.
NRC Recuest:
' Item 2.2.2.=- Incomplete.-
NUTAC-is a generic response that will need to be supplemented by plant specific information that details.how-Rancho Seco will implement the NUTAC program. This information, du'e in May,1984 has not been received.
In addition the staff found the NUTAC program fails to address the concern about' establishing ~and. maintaining an interface between all safety-related equipment vendors and the utility. The-licensee is, therefore, required to supplement his response to describe how such an interface will be developed,
~. maintained, and the current information obtained incorporated into operating, maintenance, and test procedures.

- Response:
The Vendor Equipment Technical Information Program (VETIP) as defined in the March 1984 NUTAC document is considered a valid response to section 2.2;2 of
- the NRC Generic Letter 83-28. The District is implementing the program as l
z described therein. Accordingly, it is requested that the NRC reanalyze and reconsider your request for additional information.
NRC Request:
Item 3.1.3 - Incomplete.
Licensee should report the results of their review.
Response
We have.not to date identified any post maintenance test requirements in existing technical specifications that degrade rather than enhance safety.
Existing procedure requirements ensure that this issue is part of our ongoing review of plant operations, configuration changes, and procedure changes.
NRC'Recuest; Item 3.2.3 - Incomplete.
Licensee should complete their review and report the results.
Response
See response to item 3.1.3.
NRC Recuest:
Item 4.5.2 - Incomplete.
Licensee should identify and describe modifications being made to permit on-line testing.
I
Response
The modification referred to is the addition of. automatic actuation of the shunt trip attachment (Item 4.3); which'. includes on-line testablility.- No other modifications were necessary to permit on-line testability.
NRC Recuest:
Item 4.5.3 - Incomplete.
Licensee should describe the program, discuss.the results, and furnish plant specific information regarding'how the.results will be implemented at Rancho Seco.
