Dear Mr. Glimbussor i
1 TURKEY POINT UNIT NO. 4 8
DOCKET No. 50-251 INSPECTION OF SAFETY RELATED HYDRAULIC PIPE RESTRAINTS Inspection of the safety related pipe restraints that are accessi-ble during power operation was completed on August 12, 1974, in
{
accordance with the continuing requirements of the Atomic Energy j
comunission Directorate of Licensing letter of November 8,1973.
i The inspection showed that fourteen out of fifteen restraints were
- I in satisfactory condition.
The hydraulic unit of one restraint located on the main steam piping had an indicated hydraulic fluid
.l level below the allowable limit.
This hydraulic unit was replaced l
with a spare unit.
1
{
The cause of the leakage is a mechanical wearing of the piston i
shaft seal.
The wear is caused by constant in and out movement of j
the piston shaft coupled with a slight cocking of the piston shaft due to the horizontal mounting of the restraint.
The horizontal mounting causes a downward force to be exerted on the unit just fron the unit's weight.
We have referred the problem to Bergen-Paterson and requested their assistance in providing a solution.
Very-truly yours, n
