Dear Sir:
or The Oregon Energy Facility Siting Council (EFSC) is interested in the g
timely resolution of issues related to the environmental qualification of
'f safety-related equipment at the Trojan Nuclear Plant.
This generic issue E
is addressed in part by the proposed rule 10 CFR 50.49.
=
The specific aspect of this issue addressed by the proposed rule is the qualification of safety-related electrical equipment in harsh accident environments (less seismic and dynamic considerations).
This aspect has also been the subject of discussions between Trojan's operator, Portland General Electric (PGE) and the Nuclear Regulatory Commission (NRC) for about three years.
PGE has concluded that this particular equipment is sufficiently qualified to protect the public health and safety.
In its Safety Evaluation Report, NRC concluded there are no outstanding items which require immediate action to ensure the safety of plant operation.
- 4 However, NRC identified numerous items where NRC believed additional justification or documentation is needed to ensure these items are capable of withsanding harsh accident environments.
PGE provided the requested additional information on August 26, 1981.
Using the limited technical resources available to it, EFSC reviewed this issue and agreed E
with PGE and NRC conclusions that no immediate actions were needed to f
ensure public health and safety.
EFSC further concluded that the remaining differences between PGE and NRC appear to involve technical judgements as to what constitutes qualification and how much margin is desired.
t Within the past few months, NRC has apparently begun reviewing PGE's response but has not yet completed the review and' concluded what, if any, I
equipment at Trojan will need to be replaced.
EFSC recognizes that some
!?
interim period of operations will be needed before the replacement y
equipment is tested, procured and installed.
However, no schedule for replacement can be set until NRC concludes it review.
n Further, NRC is only reviewing part of the issue at this time, but has stated its intention to review mechanical equipment, equipment in non-harsh accident environments, and seismic and dynamic considerations.
However, NRC has not yet developed criteria for these aspects.
Therefore, it is not known whether NRC agrees with PGE that Trojan's safety-related equipment is qualified for these aspects and thus no actions can be taken to resolve any potential issues in a timely m nner.

[ {p @ g /,
v Secretary of the Commission April 9, 1982 Page 2 Therefore, EFSC recommends the following actions:
1.
NRC should expedite its review of Trojan's electrical equipment in harsh environments (less seismic and dynamic considerations) so that any equipment NRC believes should be replaced can be identified and a firm schedule established considering testing, procurement, and installation times; and 2.
NRC should include in the current rulemaking all aspects of environmental qualification of safety-related equipment so that this issue can be completely resolved in a timely manner.
Thank you for consideration of our position.
Sincerely, b
