AFFIDAVIT OF JAMES H. CONRAN I, James H. Conran, being duly sworn, do depose and state:
1.
I am employed as a Principal Systems Engineer by the Office of Nuclear Reactor Regulation, U.S. Nuclear Regulatory Commission.
A copy of my professional qualifications was bound into the re-4 cord in the above proceeding following Tr. 8372, 2.
I testified at the hearing concerning UCS Contention No.14 which addressed the issue of safety classification of reactor plant equipment and corresponding design criteria to be applied.
My position as reflected in my testimony is as follows:
a)
In general, although a component or system may be classi-fied as "important to safety" (in accordance with the definition of that term in 1GCFR50 Appendix A), it need not be designed to " safety-grade" standards unless it is required for certain critical safety functions that are identified-ex-plicity in 10CFR100 Appendix A.

PER
O O
2 b) With regard to the TMI-2 accident specifically, the failure of non-safety components did contribute to the accident, and non-safety components were used in recovering from the accident. But detailed analyses performed by the NSSS vendor and reviewed by the NRR staff indicate that if installed safety systems had not been turned off by operators:
- 1) The installed safety systems would have accommodated the effects of the non-safety failures that occurred, and
- 11) operators would not have had to rely on non-safety systems (after core damage and flow blockage resulted from turning off installed safety systems) to reach cold shutdown The non-safety systems / components involved, then, need not be considered required for assurance of critical safety func tions. What is required is added assurance that operators will not improperly interfere with the operation of installed safety systems in future circumstances where their functioning is required (including response to non-safety component fail ure). A number of measures have been taken to provide l
l the added assurance required in this regard.
3.
With regard to the recommendations of the IE Operations Team, which are pertinent to the issues involved in UCS Contention No.14, to the best of my knowledge 1 was not aware of their existence until l
very recent1/ when I was informed of the intervenor's motions to l
reopen the TMI-l hearing record. Even if I had been aware earlier I
.1 3
of thnse recommendations, it would not have altered my testi-mony (written or oral) on Contention No.14 for the following reasons.
I have examined the information in the IE Operations Team report, and I find that it contains no significant in-formation or argumentation beyond that already considered in the formulation of my testimony on UCS Contention No.14. The issues involved were not raised and considered solely by the IE Operations Team. The Lessons Learned Task Force, of which I was a member, considered whether or not it was necessary to upgrade to full safety grade the non-safety components involved in the TMI-2 accident sequence and recovery. The conclusion of the Task Force was that detailed analyses should be done as a basis for determination. Such analyses were performed by the NSSS vendor and were reviewed by the NRR staff; the results in-dicated that upgrading to full safety grade was not required.
So even if I had been aware of the recommendations of the IE Operations Team, that would not have altered my testimony on UCS Contention No.14 because I relied on the results of the detailed analyses described above.
l l
The above statements are true and correct to the best of my personal knowledge and belief.
