SIXTH INTERIM REPORT 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.

Interim Progress The interim progress on these open items is listed on the attachment

Manufacturer Corrective Action /Resolutien SCNEE38023R1 TS-74 43 T657A1540 Honeywell TVA has reviewed the available TS-74-44 qualification documentation TS-44-45 for this equipment and F"s TS-44 -46 concluded that the compo nts are acceptable for use on an interim basis. These conclusions are supported in our response to NUPEG-0588.

However, to establish full equipment qualificatien, TVA will either type-test these instruments or replace them with qualified components in accordance with the guidelines and schedules of NUPIG-0588.

failure of this equipeent to TM-67-92 function properly in an TM-67-93 adverse environment dces not l

TM-67-100 affect any associated or TM-67-108 a

related plant safety function.

TM-67-109 Therefore, this equipment TM-67-101 using NUREG-0588 guidelines, meets category "C" require =ents.

Consequently, TVA may consider component replacement for reasons other than plant safety.
