NRC STAFF TESTIMONY OF ZOLTAN R. ROSZTOCZY RELATIVE TO ENVIRONMENTAL QUALIFICATION OF EQUIPMENT IMPORTANT TO SAFETY (UCS CONTENTION 12 in part)
Q.l.
Please state your name and position with the NRC.
A.
My name is Zoltan R. Rosztoczy.
I am an employee of the U. S. Nuclear Regulatory Commission and am Chief of the Equipment Qualification Branch, Division of Engineering, Office of Nuclear Reactor Regulation (NRR).
One of the sections within this branch under my supervision is the Environmental Qualification Section anc as such will evaluate the adequacy of environraental qualification of equipment at TMI-1.
Q.2.
Have you prepared a statement of professional qualification?
A.
Yes. A copy of the statement is attached to this testimony.
Q.3 Please state the nature of the responsibilities that you had with respect to the Three Mile Island Nuclear Station Unit 1.
A.
Soon after the accident at Three Mile Island Unit 2 (TMI-2) on March 20,
~
1979 I was assigned to the Bulletins and Orders Task Force (B&OTF) and was in charge of the analysis group. The B&OTF was responsible for reviewing and directing the TMI-2-related staff activities associated with r
losst of feedwater transients and small break loss of coolant accidents ;
for all operating plants (including TMI-1) to assure their continued safe operation.

m
. Q.4.
Please state the purpose of this testimony.
A.
The purpose of this testimony is to respond partially to UCS Contention 12 which reads:
"The accident demonstrated that the severity of the environ-ment in which equipment previously deemed to be environmentally qualified failed.
One example was the pressurizer level instruments. The environ-mental qualification of safety-related equipment at TMI is deficient in three respects:
- 1) the parameters of the relevant accident environment have not been identified, 2) the length of time underestimated, and
- 3) the methods used to qualify the equipment are not adequate to give reasonable assurances that the equipment will remain operable.
TMI-l should not be permitted to resume operation until all safety-related equipment has been demonstrated to be qualified to operate as required by GDC 4.
The criteria for determining qualification should be those set forth in Regulatory Guide 1.89 or equivalent."
Q.5.
Is safety related equipment at TMI-l environmentally qualified for the environments of postulated accidents?
A.
At the present time the staff has not yet c'etennined whether the safety-related equipment at TMI-1 is fully qualified to postulated accident environments.
However, the safety related equipment at TMI-i is presently under review to assure its qualification to the postulated accident environments in accordance with current criteria.
The licensee has been required to evaluate the environmental qualification of safety related elect,rical equipment and to provide the staff with the results of its eval 6ation.
I
. Q.6.
What safety related equipment has the staff required the licensee to evaluate?
A.
IE Bulletin 79-018 was issued to operating recctor licensees including TMI-1.
This Bulletin requires licensees to provide to NRC/IE an assess-ment of the environmental qualification status of all safety related electrical equipment potentially exposed to environments resulting from postulated accidents.
Q.7.
Indicate what criteria will be stilized by the staff to evaluate the environmental qualification of safety related electrical equipment at TMI-1.
A.
Subsequent to issuance of IE Bulletin 79-01B the Commission issued a Memorandum and Order (CLI-80-21, dated May 23,1980) which set forth the DOR Guidelines and NUREG-0588 as the criteria documents i
for establishing environmental qualification of safety related l
electrical equipment. These documents specify 1) the parameters of l
l the relevant accident environment, 2) the length of time that these parameters are to be imposed and 3) the methods to be used to qualify this equipment. The Order further required the staff to issue safety evaluations by February 1, 1981, addressing the environmental qualifi-cation status of safety related electrical equipment for each operating reactor.
In order to meet the February deadline established by the 1
Comission, NRR issued oroers to each operating reactor licensee, including TMI-1,_ requiring that the submittal to IE of all information supporting 1
i environmental qualification, requested in 79-01B, be completed no later than November 1, 1980. The review of this information will be perfomed
-4 by an IE Task Group. This group will generate a Technical Evaluation Report (TER) and transmit it to the Equipment Qualification Branch of NRR.
NRR will then prepare a safety evaluation report which will address the degree of compliance with environmental qualification criteria. The evaluationwilli(entifyequipmentthatisqualifiedinaccordancewith the criteria, and equipment that needs to be replaced or requalified, along with a schedule for doing so.
In addition, under the provisions of the Technical Specifications, during the review of this issue if a licensee determines that a safety related piece of equipment cannot perform its intended function during a postulated event or its failure can contribute to more severe consequences, the licensee must file a Licensee Event Repart (LER) and initiate appropriate corrective actions.
Q.8.
When will the review of the TMI-l responses to IE Bulletin 79-01B be completed?
A.
The Licensee will submit the information as required by Bulletin 79-OlB no later than November 1,1930.
The staff's review and evaluation will
~
be completed and issued by February 1,1981.
Q.9.
When will all safety related electrical equipment exposed to postulated accident environments be QJalified?
A.
By June 30, 1982 all safety related electrical equipment potentially i
exposed to environments resulting from postulated accident conditions at TMI-l shall be qualified to the DDR guidelines. Deficiencies identified will be resolved in accordance with the guidance provided in NUREG-0588.

PROFESSI0hAL QUALIFICATIONS OF Z0LTAN R. ROSZTOCZY My name is Zoltan R. Rosztoczy.
I am currently employed by the U.S. Nuclear Regulatory Commission as Branch Chief of the Equipment Qualification Branch, Division of Engineering, Office of Nuclear Reactor Regulation (NRR).
Prior to the formation of the Equipment Qualification Branch I served as Branch Chief of the Analysis Branch, NRR.
My duties and responsibilities include the supervision of the review and evaluation of the capabilities of safety related systems and components to perform their design functions under all normal, abnormal and accidental environmental conditions and in the event of seismic occurences.
I participate in the development of criteria, guides and regulations pertaining to equipment qualification.
I am a graduate of the University of Technical Sciences, Hungary.
I have also received a Master of Science degree in Mechanical Engineering from the University of California and a Ph.D. in Nuclear Engineering from the University of Arizona.
Prior to my appointment with the NRC, I was employed by Combustion Engineering Inc.,
Windsor, Connecticut (1964-1973) and by the Institute of Engineering Research, University of california (1959-1962).
During the last six years of my employment with Combustion Engineering (CE) I served as Manager, Safety Analysis.
In this capacity I was responsible for directing the safety evaluation of CE supplied nuclear power systems.
I also coordinated CE's participation in the rule making hearing on Energency Core Cooling Effectiveness.
I am a member of the American Nuclear Society and of Sigma Xi.
OUTLINE s
This testimony of Zoltan R. Rosztoczy contains the NRC Staff's partial response to UCS Contention 12.
The purpose of this partial testimony is to advise the Board and the parties that at the present time the Staff has not determined whether all safety related equipment at TMI-l is environmentally qualified.
The Licensee has been ordered to evaluate the environmental qualification of safety related electrical equipment and to submit the results of that evaluation to the Staff by November 1,1980. The criteria ajainst which the electrical equipment will be evaluated and the methods to be used to qualify it are set forth in
" Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment," NUREG-0588; and the Memorandum to V. Stello from H.
~
Denton on " Guidelines for Evaluating Qualification of Class IE Electrical Equipment in Operating Reactors" dated November 13, 1979.
The Staff will report the results of its evaluation of the Licensee's response by February 1, 1981. At that time the Staff expects to be able to take a position on whether environmental qualification of equipment is adequate to allow restart of TMI-1.
