Dear Mr. Denton:

The purpose of this letter is to. respond to the request for information trans-mitted by Mr. Robert L. Baer's letter of October 15, 1979. The response to Question 1 (tabular information) addresses only Class 1E equipment located inside containment; equipment outside containment will be addressed in sub-sequent submittals. It should also be noted that this information super-cedes previously submitted information concerning the qualification of Westinghouse supplied transmitters and RTD's located inside containment (W. O. Parker letters to Harold R. Denton dated November 20, 1978 and August 31, 1979).

Mr. Harold R. Denton, Director

'anuary J 18, 1980 Page Two As this submittal contains information proprietary to Westinghouse Electric Corporation, it is supported by an affidavit signed by Westinghouse, the owners of the information. The affidavit sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of Section 2.790 of the Commission's regulations.

Accordingly, it is respectfully requested that the information which is pro-prietary to Westinghouse be withheld from public disclosure in accordance with 10CFR Section 2.790 of the Commission's regulations. Correspondence with respect to the proprietary aspects of this application for withholding or the supporting Westinghouse affidavit should reference CAW-79-45, and should be addressed to R. A. Wiese= ann, Manager, Regulatory and Legislative Af fairs, Westinghouse Electric Corporation, P.O. Box 355, Pittsburgh, Penn-sylvania 15230.

McGuire Nuclear Station Response to NRC Request for Information Concerning Environmental Qualification of Class 1E Instrumentation and Electrical Equipment Ouestion 1:

The FSAR Tables that identify the operational requirements of equipment which .

must function during and subsequent to the design basis accidents are general and do not provide sufficient information for the review of equipment quali-fication. Therefore, provide a table listing of all Class 1E safety-related equipment and appropriate qualification related data for each as noted in the attachment. This table should include all equipment located both inside and outside of containment, including balance-of-plant and nuclear steam system supplied equipment.

Where components have been qualified by an equipment system test, identification of the equipment is sufficient, i.e., individual components need not be listed.

Equipment components should be identified where qualified by separate tests or analysis. Where more than one item of a given type is used, it is only nec-essary to present the required information for one representative item of that type for the worst case environment.

For equipment located outside containment which may not have been qualified to abnormal environmental conditions, the environmental design requirements for this equipment should be provided and noted as such in column 5. For each area of the plant where such equipment is located the normal operating extremes in environmental conditions should be provided and noted as such in column 4. A footnote should be provided for each such area to provide the basis that the normal operating extremes in environmental conditions will not be exceeded. Such basis should include the quality of environmental control systems, their redundancy, sources of power and cooling, and operating require-ments to maintain suitable environmental conditions during all modes of plant operation. The monitoring of environmental conditions in such areas and of the eq uipment controlling such environments should also be addressed to provide assurance that such conditions are maintained.

Response

See attached table and notes for Class IE equipment located inside containment.

Question 2:

IEEE Std. 323-1971 does not specifically address aging mechanisms as a consid-eration in the qualification of safety-related electrical equipment. Subsequently, IEEE Std. 323-1974 addressed aging in the sequence of factors to be considered.

While for many components, aging may not play a significant role in the ability of a component to withstand the effects of an abnormal or accident environment and still perform its required function; there are certain materials which may be subjected to degradation over a long period of time. It is the staff's position that applicants with qualification programs for safety-related electrical equipment, conducted in accordance with IEEE Std. 323-1971, should undertake an investigation of the electrical equipment to ensure that significant aging mechanisms do not exist which could invalidate the conclusions of prior cualifi-cation. Sources of information, specifically material manufacturers data, should 1794 122

~

_2-be consulted as a part of this review. Therefore, you are requested to conduct such an evaluation and to report your findings at the earliest opportunity. For any equipment for which significant aging mechanisms are identified, provide the justification and time interval for acceptable use of this equipment which does not invalidate its prior qualification or provide other proposed alternatives such as requalification or replacement with qualified equipment and not subject to aging concerns.

Response

Duke Power Company will evaluate the in-containment Class lE equijment for signi-ficant aging mechanisms. While only limited data is available on specific materials utilized in this equipment, actual in-service experience with equip-ment of this type has not demonstrated significant aging mechanisms. However, we will investigate the in-containment Class lE equipment and report at the time of discovery any equipment for which significant aging mechanisms are identified including the justification for cintinued use and/or reasonable alternative action. This on-going investigation will necessarily be very time consuming and will rely heavily on EPRI research, NRC studies, NPRDS information, IE Bulletins and Circulars, and industry research and testing.

1 of 2 Revision 0 McGuire Nuclear Station Environmental Qualification of Class lE Equipment Located Inside Containment Note 1 All equipment identified in this table is located inside the containment, specifically in the lower compartment except for the electric hydrogen recombiner, containment air return fan motors, hydrogen skimmer fan motors, containment air return isolation damper motors, differential pressure switches for damper control and cables associated with these devices which are located in the upper compartment.

Note 2 The parameters that compose the overall worst-case containment accident environment are as follows: .

Temperature (Upper Compartment): 180F peak; time history as shown in FSAR Figure 6.2.1-24 (Rev 36)

Temperature (Lower Compartment): 327F peak; time history as shown in FSAR Figure (LATER-to be provided in FSAR Revision 39)

Pressure (Upper and Lower Compartment): 14.8 psig peak; time history as shown in FSAR Figure 6.2.1-23 (Rev. 36)

Relative Humidity: 100%

Radiation: Total integrated radiation dose for the equipment location includes 40 year normal operating dose plus the appropriate accident dose (except for the narrow-range and wide-range RTD's).

Chemical Spray: Boric acid and sodium tetraborate spray resulting from mixing in the containment sump of borated water from the RWST and sodium tetraborate solution from ice bed melt.

Note 3 Equipment operability requirements in the containment accident environment are as identified in FSAR Table 3.11.1-1 (Rev. 25).

Note 4 Environnental qualification test reports for the following equipment have previously been submitted to the NRC Staff:

Note 5 Qualification tests for the Barton Lot 2 transmitters have been completed, and the results are being compiled by Westinghouse into a report for submittal to the NRC Staff.

Note 6 -

Electric penetration types B,C,F, G and K are the only penetraticns required to function electrically in the containment accident environment. All electric penetrations, however, are designed and qualified to maintain their mechanical integrity under normal and postulated accident environmental condi tions .

Note 7 The McGuire electric penetrations are protected from direct spray impinge-ment by galvanized steel boxes.

Note 8 This item is being pursued with the cable manufacturer. We will report our findings in a future revision to this table.

Note 9 The containment pressure sensor devices are made of stainless steel and therefore not degraded by chemical spray.

Note 10 The containment pressure sensors and associated transmitters were qualified as a system. The overall accuracy requirement for the sensor / transmitter combination is +0%, -10% of span. The demonstrated accuracy of this combination during testing was within the accuracy requirements.
