Dear Mr. Keiser:
Subject: NRC Region I Combined Inspection 50-387/92-02; 50-388/92-02 and
The enclosed report documents
a safety. inspection conducted by our senior resident inspector
from January
1, 1992 - February 10, 1992, at the Susquehanna
Steam Electric Station
(SSES), Salem Township, Pennsylvania.
The inspection covered your conduct of licensed
activities for both units. At the conclusion of the inspection, Mr. 6, S. Barber, Senior
Resident Inspector, summarized the inspection findings with Mr. T. C. Dalpiaz and other
members of your staff.
During this inspection, we focused particular attention to the hydrogen gas detonation event
of January
18, 1992, involving repair activities to the common off-gas recombiner system.
We recognized that, as a result of this occurrence,
your staff initiated an aggressive
investigation effort to identify root causes
and corrective actions.
We are satisfied that your
effort was sufficiently comprehensive
and thorough.
As a result of your investigation of this self-disclosing event, your staff identified several
weaknesses.'elative
to these findings, we are particularly concerned about (1) the apparent
ineffective incorporation of notifications, information, and communications of previous
industry events involving combustible gas hazards associated
with off-gas systems into
pertinent plant procedures
and practices;
(2) the failure to adequately track the status of the
1989 repair activity involving the globe valve (HV-16907) that was used to isolate the
common recombiner system in this instance;
and (3) the failure to adequately investigate the
cause for the unusual off-gas instrument indications on January
16. 1992, which were
apparently caused by a small hydrogen detonation at that time.
Relative to these matters, we
are continuing to review your process for handling generic communications and notifications
of previous industry events; and have identified the remaining items as apparent violations as
described in the enclosed Notice of Violation.
