Reading, Pennsylvania 19603 GLear Bridges Gentlemen:
SATeets SVarga In the su=mer of 1973 a significant number of hydraulic shock suppressors (snubbers) were found to be inoperable at many reactor facilities.
Ibe failures were caused by severe degradation of seal materials and subsequent leakage of hydraulic fluid.
An extensive seal replacement program has been carried out wt. ich has significantly reduced the incidence of snubber failures.
Uovever, failures continue to occur.
Our review of snubber experience at reactor facilities indicates a need for technical specifications requiring snubber operability and surveillsace. We have prepared model technical specifications and bases which will provide additional assurance of satisfactory snubber performance and reliability.
A copy of these specifications is enclosed.
Since these were not prepared explicitly for your plant, some editing tiay be necesrary in order to adapt them to the Three P.ile Island Unit I design and nomenclature.
You are requested to submit within 45 days from your receipt of this letter an application for amendment to your license that would change your technical specifications to be in conformance with the requirements of the enclosed model technical specifications.
Sincerely, M/
/ JJ George Lear, Chief Operating Reactors Branch J3 Division of Reactor Licensing
