SUBJECT:
Grand Gulf Nuclear Station Units 1 and 2
, Docket Nos. 50-415 and 50-417
. File 0272/M-632.0/M-222.0 Transmittal of Proposed Technical Specification Change, Post-LOCA Vacuum Relief and Drywell Purge Vacuum Breaker Position Indication
. AECM-82/186 This letter transmits a proposed revision to the GGNS Technical Specifications pertaining to the drywell post-LOCA vacuum breakers and supporting justification. Associated with this issue are certain in-strumentation changes for the check valves in the post-LOCA vacuum relief and drywell purge systems.
Both the post-LOCA vacuum relief and the drywell purge systems consist of a motor operated butterfly type isolation valve in series with the vacuum breaker check valve (s) which provides drywell vacuum relief.
Both the vacuum breakers and isolation valves were provided with, position
- . indication. (See GGNS FSAR Figure 6.2-81).
During onsite testing of the vacuum breakers (check valves F001A,B, F002A,B, and F004A,B in FSAR Figure 6.2-81) to assure actuation on 1.0 psid pressure, several factors caused sufficient resistance to prevent the proper opening and closing of the valves. The valves were reworked and modified to operate within their design requirements, however, the lever arms when contacting the position switches did not allow the valves to fully close. Therefore, the position switches and lever arms were subsequently removed from the check valves.
The motor operated isolation valves which are in series with the check valves, operate by the same 1.0 psid pressure and are provided with position indication. Based on this, Mississippi Power & Light (MP&L) contends that position indication on the check valve vacuum breakers is not required.

. MISSISSIPPI POWER & LIGHT COMPANY 9' t' .
A proposed revision to Section 3/4.6.5, "Drywell Post-LOCA Vacuum Breakers," of the GGflS Technical Specifications is attached.
The Limiting Condition for Operation and Surveillance Requirements are revised to indicate the use of position indication on the isolation
- valves instead of the vacuum breakers. The Technical Specifications on the Drywell , Purge System are presently correct and no revision i is required.
In addition, two other corrections are provided in Technical Specification Section 4.6.5, which indicate a revision to the surveillance
, requirements based on .the GGflS post-LOCA vacu.um breaker design.
Subsection 6.2.5.5 of the GGflS FSAR was revised in Amendment 55 to show position indication only on the isolation valves in the post-LOCA and drywell purge systems. FSAR Figure 6.2-81 will be revised in a future amendment to delete positi,on indication on the check valves discussed above.
flotwithstanding the above, MP&L intends to provide position indication with qualified non-contact type switches on the vacuum breakers as an operator aid. Switches for this application, qualified to flVREG-0588, are currently not available but are expected to be provided during the first regularly scheduled refueling outage.
This modification is being proposed as an operator convenience and is not considered a licensing requirement.
Please advise if any additional information is required. -
