IE Bulletins / Circulars
The inspection included followup on licensee actions related to the
following IE Circulars:
IE Circular 78-13, inoperability of Service Water Pumps
(Closed): An internal memorandum discussed the inspection of
the plant's service water intake for silting.
A facility
representative confirmed that a diving contractor had removed
a nominal amount of silt at the intake and that an annual
inspection had been added to the plant's preventive maintenance
program.
IE Circular 78-15, Check Valves in Vertical Position (Closed):
A licensee representative stated that this Circular had been
reviewed and that no tilting disk check valves were installed
in safety applications at Trojan.

Licensee Event Report
The inspectors reviewed corrective actions in progress related to
LER 78-20, Grouting of Piping Penetrations.
Revision 2 to LER 78-
20 included a list of 17 penetrations requiring corrective actions.
Previous inspections included review of the licensee's activities

in surveying and analyzing plant systems to establish this list.
Corrective actions were completed >for at least three of the penetra-
tions and in progress for several others.
A licensee representative
stated that one of the 17 penetrations had been re-evaluated and
would not require corrective actions; another revision to LER 78-20
will document this.
Implementati.on of the corrective actions will
be reviewed further during future inspections.
No deviations or items of noncompliance were identified.
4.
Independent Inspection Effort
The inspectors toured various areas of the plant to observe general
plant conditions. While looking at piping penetrations, the in-
spectors observed that one primary containment penetration (hydrogen
vent exhaust, penetration No. P-72) had wooden wedges inserted in
the annulus between the pipe and the outer wall of the penetration
assembly.
It appeared that the wedges could have been used for
temporary support of the pipe, such as during maintenance on an
adjacent valve.
The licensee stated that no record concerning
installation of the wedges could be found, and that they would be
removed.
No deviations or items of noncompliance were identified.
5.
Exit Interview
The inspectors met with licensee representatives (denoted in Para-
graph 1) at the conclusion of the inspection on December 1,1978.
During the exit interview, the inspectors summarized the scope and
findings of the inspection as set forth in Paragraphs 2 through 4.
