Previously Identified Followup Items
a.
(Closed) 50-312/30-12/01, 02 and 03:
Review of components
listed on " Master List".
During a review of the containment isolation system in April 1980,
several discrepancies were noted between the master list prepared
for tne 45 day submittal to IEB-7901B (March 3,1980) and
installed equipment, particularly with solenoid pilot valves and
limit switches.
These items appear to be correctly listed on
the licensee's October 31, 1930 response.
lne containment
isolation system outside containment was reviewed and compared
to the October 31, 1980 master list.
No problem areas were
noted. This item is closed.

Review of Licensee's Response to IE Bulletin 79-01B
a.
Background
IE Bulletin 79-01B was issued to obtain additional information
needed to resolve safety concerns related to current qualification
criteria for Class IE electrical equipment installed in potentially
harsh environments.
The licensee's responses to the bulletin are detailed in licensee
letters dated July 9, 1979,flarch 3, May 5 and October 31, 1980.
The October 31, 1980 response was considered to be the final
response and included all safety related equipment required to
mitigate an accident and bring the plant to a safe cold
shutdown condition.

IE Inspection Actions
The objective of the inspect an was to review the licensee's
October 31, 1980 subnittal and verify that the licensee had
adequately evaluated environmental qualification of safety
related electrical equipment.
The inspector considered the
criteria presented in Division of Operating Reactors'
" Guidelines for Evaluating Environmental Oualification of
Class IE Electrical Equipment in Operating Reactors" in the
conduct of this review.
Pursuant to these examinations a Technical Evaluation Report
was submitted to IE Headquarter on December 15, 1980.
c.
Findings
The Technical Evaluation Report (TER) identifies Class IE
electrical equipment, subject to harsh environments, whose
qualification is unresolved, not qualified or cualified with
restrictions.
The TER provides a clear statement of the
problem, the licensee's plans to resolve the problem and the
licensee's basis for continued operations.
The licensee committed to provide an updated submittal
detailing the problem areas and the results of their evaluation
per bulletin requirements by January,1981.
The licensee has committed to provide a submittal by
February 1,1981, detailing environmental qualification of
electrical equipment installed pursuant to the TMI action
plan.
