SEQUOYAH NUCLEAR PLANT UNIT 2 ENVIRONMENTAL QUALIFICATION OF ELECTRICAL EQUIPMENT NCR SQNEEB8023 (AND OTHERS) 10CFR50.55(e)
NINTH REPORT (FINAL)
Description of Deficiency During the review of qualification records for electrical equipment required by NUREG-0588, a number of components were identified as having inadequate documentation to verify their qualification levels for the harsh environments resulting from abnormal or accident conditions at the plant. A listing of the subject components is attached to this report.
Safety Implications The equipment identified in this report is located in a number of auxiliary systems within the plant. Some of these systems are required to mitigate the effects of postulated accident sequences.
If, during an accident, one of these components were to fail in the harsh environment created by the accident, this failure could possibly result in interrupting operation of a system (s) required to perform a t
direct accident-mitigating function.
Corrective Action The corrective action to be taken on these open items is identified on the attachment to this report.
The basic cause of the condition described in this nonconformance report was inadequate provisions in the TVA procurement specifications for requiring equipment vendors to supply the necessary environmental qualification documentation for their components. The lack of readily available documentation, together with the indeterminant status of l
some "as-installed" component types and model numbers increased the l
time required to evaluate and disposition the individual problem l
- areas, i
i To rectify the condition described above, TVA is taking steps to enhance future procurements of class 1E electrical equipment in the area of environmental qualification documentation. These efforts include the development of environmental design criteria for Sequoyah and Watts Bar (similar criteria presently exists for Bellefonte and Yellow Creek). This document will specify environmental conditions for qualification of equipment and design of environmental control The Sequoyah criteria was issued on July 16,198E.and accident).
systems for all plant conditions (normal, abnormal Also, guidelines have been distributed by memorandum related to future class 1E electrical equipment purchases which require the identification of pertinent environmental conditions (including magnitude and durations) in which the subject equipment must operate for inclusion (as equipment qualification requirements) in the bid specifications issued to vendors.
It is now recognized by TVA and the nuclear industry that plant designs must be evaluated for compliance with the requirements of NUREG-0588 prior to receipt of an operating license. As a result, program plans have been developed and issued to accomplish this work for Watts Bar and Bellefonte. These program plans outline a systematic assessment for calculating plant environments as a result of postulated loss-of-coolant accidents (LOCA) or high energy line breaks (HELB), defining the plant boundaries for these accident environments, identifying the systems and components important to safety, initiating field inspections to verify the actual equipment.
installations, and reviewing the available environmental qualification documentation on these components. Equipment found to be in noncompliance with the guidelines of NUREG-0588 will be tabulated and reported to the NRC as required. In conjunction with this program, a separate program, previously established for Browns Ferry and Sequoyah, will be developed for Watts Bar and Bellefonte to track the qualification lifetimas of this equipment and replace components as their " qualified" lives expire.
TVA also recognizes that the issue of environmental qualification of electrical equipment is being pursuied by the NRC in the form of a revision to the Code of Federal Regulations (reference proposed rule 10CFR50.49 in the January 20, 1982, Federal Register). We expect to follow the dispositioning of this proposal for future Lapacts upon our program plans.
As for plants beyond Bellefonte, TVA will document the environmental qualification levels of the electrical equipment to be installed on a schedule consistent with the overall plant design, construction, licensing, and operation schedules.

Manufacturer Corrective Action / Resolution SQNEEB8023R1 TS-74-43 T657A1540 Honeywell TVA has reviewed the available TS-74-44 qualification documentation for this equipment and has TS-74-45 concluded that the components TS-74-46 are accept.:ble for use on an interim basis. These conclusions are supported in our response to NUREG-0588.
However, to establish full equipment qualification, TVA will either type-test these instruments or replace them with qualified components in accordance with the guidelines and schedules of~NUREG-0588.
SQNEEB8024 Essential 101HA1-6HD9810 Pall Trinity TVA has determined that this Control Air -331 Corporation equipment is not located in a potentially harsh environment Dryer resulting from an accident.
Therefore, this equipment, using NUREG-0588 guidelines, meets Category "D" requirements.

FM-30-149A TVA has determined that the TM-67-84 SW611 failure of this equipment to TM-67-85 function properly in an TM-67-92 adverse environment does not TM-67-93 affect any associated or TM-67-100 related plant safety function.
TM-67-108 Therefore, this equipment TM-67-109 using NUREG-0588 guidelines, TM-67-101 meets category "C" requirements. Consequently, TVA may considor component replacement for reasons other than plant safety.

This change has been incorporated into the plant operating procedures.

FS-30-187 In the last response to SQN FS-30-200 EEB 8036R2, TVA indicated that FS-30-207 flow switches FS-30-200 and FS-30-207 were not qualified for the postulated accident environment and would be relocated to a more suitable environment before initial criticality. Alternately, new switches were procured and installed; however, post modification testing showed the switches to have an unacceptably slow operation time.

TVA has evaluated the function of these switches to determine the safety implications of their inoperability. The switches are installed on the Emergency Gas Treatment System room coolers. The switches were designed to automatically start the standby cooler upon low flow to the operating cooler. Operating practices, however, require both fans be lined up in automatic building isolation ( ABI) or when the-room temperature reaches a predetermined setpoint, both fans will automatically start and run until the ABI is reset and/or the temperature is reduced. TVA concludes this is an acceptable mode of operation and that the failure of the subject flow switches will not prevent these cooling fans from performing their intended functions.
