Dear Sir:
Three Mile Island Nuclear Station Unit 1 (TMI-1) Operating License No. OPR-50 Docket No. 50-289 Environmental Qualification (SBLOCA/ Radiation) In response to your lettar of August 8,1984, enclosed as Attachment 1 is the master list of the electrical equipmaat located in a harsh radiation environment that is necessary to mitigate srtall break LOC 4s and loss of main feedwater transients. This list was prepared in accordance with the guidance provided in your letter of May 25, 1984. Radiation qualification information for those components in Attachment I will be available for "eview durirg the NRC audit scheduled for August 29-30, 1984. Attachment 2 lists the additions / deletions made since our letter of May 18, 1981 along with reasons for them. Attachment 3 describes the resolution of equipment items whose radiation qualification documentation is incomplete at the time of this letter. GPUN affirms that the environmental qualification files for the components in Attachment 1 (as modified by Attachment 3) adequately demonstrate SBLOCA qualification for radiation levels associated with large break LOCAs in accordance with the 00R Guidelines. As permitted by the D0R Guidelines (Section 4.1.2), TMI-l plant application specific large break LOCA radiation doses were calculated for 8408280178 840823 PDR ADOCK 05000289 P PDR d GPU Nuclear is a part of the General Public Utilities System ,it

(6) These components perfonn their required function prior to being exposed to the harsh-radiation environment due to recirculated radioactive fluids and their. subsequent possible failure as a-iresult of the. harsh environment will not affect safety. (7) These components are not required ~to perform a safety function .during or following exposure to a harsh radiation environment. created by a SBLOCA,-and failure of the equipment will not affect safety., .t (8) -This solenoid valve controlled pneumatic ~ operator with seperate ' limit switches was replaced by a solenoid operator with self contained limit switches. i i Ir/0363e-i i

RESOLUTION OF EQUIPMENT ITEMS WHOSE RADIATION QUALIFICATION DOCUMENTATION IS-INCOMPLtIt iThe following'is;a' list of equipment required for small break LOCA.. ' mitigation whose radiation qualification has not_been fully established -including a description of the resolution'for each item: l. Incore Thermocouples- ~ While qualification of the incore. thermocouple ~ indicating system to; i the D0R Guidelines-large break LOCA radiation level has not yet been fully documented, operating experience _ demonstrates that forty-six ~ (46)_of the fifty-two (52)-identical' units at TMI-2~are still-operational after'more than five years since the accident and exposure-4 ~to approximately one Megarad gamma integrated dose. We are not aware ' of anything in the TMI-2 incore thermocouple system which suggests 1 that the failures were due to radiation..The configuration and-U materials of the incore-thermocouple system at TMI-1-are similar to that in TMI-2. This operating experience provides a basis for. concluding that this equipment will-perform its function when required. -2. MU-P3A/B/C (Make-up Main Lube Oil Pump Motors)- Radiation qualification for these motors to the D0R Guidelines large break LOCA radiation dose will either be demonstrated prior to restart or these motors will be replaced with qualified units or a JIO will be provided. 3. Rosemount RTD Model Nos. 177HW and 177GY ,J r Beta shields will be installed on the RTD head assemblies such that the ethylene propylene 0-ring is shielded from beta radiation. The-L beta shields will be installed prior to restart. With beta shields installed,~these-RTD's are qualified. '4.- Limitorque Valves (DHV-4B; 7A/B; NSV-4, 15,35; CAV-1,3,13; MUV-12,2A/B,25; WDG-V3; WDLV-303; ICV-V2) The material used in the existing splices ~on these operators will be replaced with qualified splices prior to restart. Additionally, documentation for the sealing compound material for the Dings brakes (DHV-4 A/B only) is incomplete, but should be available for the audit. Should this documentation show that the brakes are unqualified, they will be replaced or'a JIO will be provided. i 5. Samuel Moore Instrumentation Cable (PT-9818) I The cable for Rosemount pressure transmitter PT 981B was supplied by ' l Samuel Moore Corporation. We are in the process of researching the radiation qualification documentation for this cable. We will have ? - the radiation qualificatio'n file-available by the audit date,-or the cable will be replaced prior to restart, or a JIO will be prepared. 0505M w -.,+,w-r-
