Dear Mr. Byram:
SUBJECT:
NRC REGION I COMBINED INSPECTION 50-387/93-13; 50-388/93-13
The enclosed report documents
a resident safety inspection conducted by Messrs.
G. S.
Barber and D. J. Mannai, and others from August 18, 1993 through October 4, 1993, at the
Susquehanna
Steam Electric Station (SSES), Salem Township, Pennsylvania.
The inspection
covered plant operations,
surveillance, and maintenance for both units. At the conclusion of
the inspection, Mr. G. S. Barber, Senior Resident Inspector, summarized
the inspection
findings with Mr. H. G. Stanley and other members of your staff.
During the period, a safety related Circle Seal Solenoid Operated Valve (SOV) failure caused
an unplanned Engineered
Safety Feature (ESF) actuation.
Your staff initiated a detailed
investigation which determined breakdown of the coil wire insulation caused the SOV failure.
This course of action was considered prudent given the industry history of SOV failures.
SOV failures are of particular concern due to the potential for common-mode failures or
degradations of safety related systems.
We understand
that you willbe providing the failure
analysis details and a history of Circle Seal SOV failures at Susquehanna
in a supplemental
Licensee Event Report (LER).
As a result of our review of a previous open item we noted your positive corrective actions
for area contaminations
that occurred during spent fuel cooling demineralizer backwashes
and
precoats.
As a result, we have chosen not to cite a procedure violation that resulted in one
of the contaminations.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and
its enclosures will be placed in the NRC Public Document Room.
