The only known outstanding action item, as outlined in the attached report, is the installation of a water-tight fitting on
'the Victoreen Radiation Detectors. These detectors were installed g , fg/gs (
as an enhancement to the radiation monitoring system to satisfy the requirements of NUREG-0737 and would be used to detect a radiation release due to a potential breach of the reactor coolant pressure boundary. The radiation detectors will be considered qualified upon completion of the water-tight fitting installation currently being implemented during the present refueling outage.

Equipment submergence (inside or outside containment) should be addressed where the possibility exists that submergence of equipment may result from HELBs or other postulated occurrences. Supplement 2 to IE Bulletin 79-01B (20)
_, provides the following additional criterion: If the equipment satisfies the guidance and other requirements of the DOR Guidelines or NUREG-0588 for the LOCA and HELB accidents, and the licensee demonstrates that its failure will not adversely affect any safety-related function or mislead the operator after submergence, the equipment can be considered exempt from the submergence portion of the qualification requirements.
APC Response:
With the qualified life clarification provided in Part A above, the ASCO NP/206 series solenoid valvas located inside the containment satisfy the guidance and other requirements of the DOR guidelines or NUREG-0588 for the LOCA and HELB accidents.
Appendix 1,Section II.D, which was included in Rev. 5 to APC's July 30, 1980, submittal, " Joseph M. Farley Nuclear Plant Unit - 1 Response to the NRC IE Bulletin 79-01B," and was forwarded to the NRC on August 25, 1981, demonstrated that solenoid valves (Q1E21SV8149AB, BB, CB) and
- (QlE21SV1003B) will perform their safety function prior to becoming submerged, their further operation is not required, and their failure does not affect other safety-related equipment or mislead the operator. Therefore, these C>3 solenoid valves should be considered exempt from the submergence portion of the qualification requirements.

- 3. As discussed in Appendix 1,Section II.D, the solenoid valves addressed above will perform their safety functions prior to being_ submerged. Their safety functions are to go to the vent position following de-energization of the solenoid which permits air to be vented from the operator of the air operated isolation valve. Venting the air permits the isolation valve to go to its fail safe position (closed). These solenoid valves will not be required to change position after being submerged. Appendix 1,Section II.D, provided a failure mode analysis for the solenoid coil under the submerged condition. There are no other solenoid valve internal components which due to submergence or in-leakage could effect the isolated (closed) position of the isolation valve.

Supplement 2 to IE Bulletin 79-OlB (20) provides the following additional criterion: If the equipment satisfies the guidance and other requirements of the DOR Guidelines or NUREG-0588 for the LOCA and HELB accidents, and the licensee demonstrates that its failure will not adversely affect any safety-related function or mislead the operator after submergence, the equipment can be considered exempt from the submergence portion of the qualification requirements.
APC Response:
With the qualified life clarification provided in part A above, the ASCO NP/206 series solenoid valves located inside the containment satisfy the guidance and other requirements of the DOR guidelines or NUREG-0588 for the LOCA and HELB accidents.
Appendix 4,Section II.C, of " Joseph M. Farley Nuclear Plant Unit 1 Response to the NRC I.E. Bulletin 79-01B," and was forwarded to the NRC on August 25, 1981, demonstrated that solenoid valve (Q1G21SV3376) !
, will cerform its safety function prior to becoming submerged. Alabama Power Company has concluded that its failure does not affect other safety related equipment nor mislead the operator. Therefort, this solenoid valve should be considered exempt from the submergence

- 3. As discussed in Appendix 1,-Section II.D, the solenoid valves addressed above will perform their safety functions prior to being submerged. Their safety functions are to go to the vent position following de-energization of the solenoid which permits air to be vented from the operator of the air operated isolation valve. Venting the air permits the isolation valve to go to its fail safe position (closed). These solenoid valves will not be required to change position after being submerged. Appendix 1,Section II.D, provided a failure mode analysis for the solenoid coil under the submerged condition. There are no other solenoid valve internal components which due to submergence or in-leakage could effect the isolated (closed) position of the isolation valve.

Section 7 of the DOR Guidelines and Section 4.1, Category II of NUREG-0588, do not require a qualified life to be established for all safety-related electrical equipment located in harsh environments.
An acceptable method for addressing in-service degradation is through a preventive maintenance / surveillance program with equipment and component refurbishment and/or replacement based on known susceptibility to aging degradation, the results of inspection, or manufacturern recommendations. These elements of the program lead to an understanding on a device-specific basis of the nature and extent of the increased stress level encountered during Design Basis Accidents and lesultant degradation (if any) which may occur. Arrhenius or other appropriate accelerated

An Environmental Qualification Administrative Program is being imple-mented for the RTDs which includes a preventive maintenance /
surveillance program with equipment and component refurbishment and/or replacement based on known susceptibility to aging degradation, the results of inspection, and manufacturers recommendations. These RTDs have been determined to have a 40-year qualified life based on a thermal and radiation evaluation described below.
B. QOALIFIED LIFE OR REPLACEMENT SCHEDULE ESTABLISHED Following are the results of the Westinghouse Thermal Aging Analysis, which were transmitted to APC in their letter APW-A-6006, dated June 14, 1982.
- 1. Lead Wrapping - Silicone-Impregnated Fiberglass Thermal data on silicone-varnished glass cloth yields a 40-year-life temperature of 140-180 C using 50 percent retention of dielectric strength.
- 2. Insulating Tubing - Polyolefin g]
W Testing of Polyolefin cable insulation was conducted by aging samples in ovens and periodically subjecting them to 2000 volts after soaking them in water and wrapping them around mandrels. The criterion used for end of life was dielectric failure under such conditions. The extrapolated 40-year life for samples wrapped on a 2X mandrel is 100*C.
- 3. Epoxy - Novalac The 40-year extrapolated life based on 70 percent retention of initial flexural and impact strength is 90*C for an anhydride-cured epoxy Novalac.
- 4. Packing - Mica Quartz l
l This material does not contain organic substances and is not evaluated for aging effects.
- 5. Swaged Insulation - N/A (Crimped)
I j ,6. Wire Insulation - Silicone Rubber l
l Testing of silicone rubber has indicated that degradation is extremely slow at temperatures from 150*C to 230*C. The 40-year-li fe tempera-ture is 70*C which envelops the Farley Nuclear Plant conditions.

D. CRITERIA REGARDING FUNCTIONAL TESTING SATISFIED i
() The RTDs are calibrated by the vendor at 32*F, 525*F, and 625*F, which demonstrates accuracy over the temperature
) range of interest. Although it is difficult to provide an j exact accuracy statement during the transient (the sensing end was exposed), the HELB test does demonstrate that the RTDs responded to the HELB temperature without exhibiting noticeable errors. Calibration checks after the test'also
- provide additional support. ,
E. CRITERIA REGARDING INSTRUMENT ACCURACY SATISFIED i
l The temperature deviation _was expressed as a percent of the span between the selected test temperatures.when, in l reality, the error expressed as a percent of the real span -
(670*F) would be much lower. The test report concludes that the environmental test results demonst' rate that the RTDs meet or exceed all minimum performance requirements.

() 3. Electrical connections, e.g. , splices, connectors, were not part of the RTD qualification program. Nonetheless, Alabama Power Company has provided fully qualified cabling, cable splices, and other necessary electrical components to ensure that electrical signals are trans-mitted under accident conditions.
- 5. The W test program was not intended to prove Rosemount's
, internal acceptance criteria. The W specification does require a repeatability throughout the range of +0.2*F. As the report states, difficulties were encountered with the calibration equipment which tended to cause excessive deviations in a few sensors.
4 The 2 out of 3 acceptance criteria is based on Westinghouse engineering judgement and experience.
- 6. See Clarification "E."
- 7. No comment is required.
- 8. The operating time requirements for the narrow range RTD may be found in the safety analysis report. However, the total test time should provide adequate assurance since this far exceeds trip time requirements. Margins for trip function requirements are contained in the HELB envelopes
(() which encompass a full spectrum of break sizes and are also justified by the fact that the signal generated by the
, sensor is " locked-in" by the protection system and will not
! reset should the sensor fail after the designated trip time requirement.
- 9. No comment is required.
- 10. As stated in WCAP-9157 the Rosemount Model 176KS and 176KF RTDs have been qualified in the qualifications program to a total integrated dose of 1 x 10'R gamma. The wide range RTDs used to measure THOT and TCOLD are R semount Model l 176KS and are located on the RCS hot and cold leg piping.
The narrow range RTDs used to measure RCS temperature are Rosemount Model 176KF and are located on the RTD bypass manifold. A material evaluation of the Rosemount Model 176KS and 176KF RTDs has determined that there are no radiation susceptable materials contained in the portion of the RTDs which is in contact with the reactor coolant. All radiation susceptable materials are located in the portion of the RTDs which is external to the RCL pipe and the
, bypass manifold pipe.

APC Response:
An Environmental Qualification Administrative Program is being imple-mented for the RTDs which includes a preventive maintenance /
surveillance program with equipment and component refurbishment and/or replacement based 'on known susceptibility to aging degradation, the
, results of inspection. and manufacturers recommendations. These RTDs
- have been determined to have a 40-year qualified life based on a thermal and radiation evaluation described below.
B. QLJALIFIED LIFE OR REPLACEMENT SCHEDULE ESTABLISHED Following are the results of the Westinghouse Thermal Aging Analysis, which were transmitted to APC in their letter APW-A-6006, dated June 14, 1982.
- 1. Lead Wrapping - Silicone-Impregnated Fiberglass 4 Thermal data on silicone-varnished glass cloth yields a 40-year-life temperature of 140-180*C using 50 percent
. retention of dielectric strength.
- 2. Insulating Tubing - Polyolefin f
Testing of Polyolefin cable insulation was conducted by
~ t aging samples in ovens and periodically subjecting them to 2000 volts after soaking them in water and wrapping them around mandrels. The criterion used for end of
- life was dielectric failure under such conditions. The extrapolated 40-year life for samples wrapped on a 2X mandrel is 100*C.
- 3. Epoxy - Novalac The 40-year extrapolated life based on 70 percent retention of initial flexural and impact strength is 90*C for an anhydride-cured epoxy Novalac.

The material aging analysis reports are applicable to FNP and are maintained on file at Westinghouse Water Reactor Division.
C. CRITERIA REGARDING SPRAY SATISFIED Spray was injected via main inlet steam piping to test chamber over the first 24 h at a range of 6.0 gal /h and a concentration of 1.14 weight percent boric acid and 0.17 percent sodium hydroxide dissolved in water.
D. CRITERIA REGARDING FUNCTIONAL TESTING SATISFIED gr T t \_) The RTDs are calibrated by the vendor at 32 F, 525*F, and 625*F, which demonstrates accuracy over the temperature range of interest. Although it is difficult to provide an exact accuracy statement during the transient (the sensing end was exposed), the HELB test does demonstrate that the RTDs responded to the HELB temperature without exhibiting noticeable errors. Calibration checks after the test also provide additional support.
E. CRITERIA REGARDING INSTRUMENT ACCURACY SATISFIED The temperature deviation was expressed as a percent of the span between the selected test temperatures when, in reality, the error expressed as a percent of the real span (670*F) would be much lower. The test report ' concludes that the environmental test results demonst' rate that the RTDs meet or exceed all l minimum performance requirements.

The narrow range RTDs usea to measure.RCS temperature are j Rosemount Model 176KF and are located on the RTD. bypass manifold. A material evaluation of the Rosemount Model 176KS and 176KF RTDs has determined that there are no radiation susceptable materials contained in the portion of the RTDs which is in contact with the reactor coolant. All radiation susceptable materials are located in the portion
~
of the RTDs which is external to the RCL pipe and the bypass manifold pipe.
An analysis has been performed for the wide range RTDs (176KS) based on a 40-year normal operating dose (WCAP
< 8587, Rev. 4) and a two week post-DBE integrated gamma dose taking into consideration the relative position of the j radiation susceptable materials to the RCL pipe.

material qualification to a total integrated dose of 1 x 10'R gamma per WCAP-9157, and based on the normal and accident integrated dose analysis considering the relative position i-
EQUIPMENT ITEM NO. 19 of the radiation susceptable materials to the RCL pipe, the Model 176KS RTDs are radiation qualified for greater than 40 years of operation.
The narrow range RTDs Rosemount Model 176KF do not perform any long-term post-accident monitoring function. They will-per'orm their intended reactor trip function approximately 30 s after the DBE. An analysis has been performed for the narrow range RTDs (176KF) based on a 40 year normal operating gamma dose and a 1-h post-DBE integrated gamma dose taking into consideration the relative position of the radiation susceptable materials to the RTD bypass manifold pipe and the RCL piping. Based on material qualification to a total integrated dose of 1 x lO'R gamma per WCAP-9157 and based on the normal and accident integrated dose analysis considering the relative positon of the ,.

Farley Nuclear Plant - Unit 1 Response to the NRC I. E.
Bulletin 79-01B," which was forwarded to the NRC dated December 28, 1981,.it was stated that these pressure transmitters would be relocated above the flood level during the 3rd refueling outage. The subject transmitters were relocated above the flood level during the third refueling outage as stated in the reference submittal.
C. CRITERIA REGARDING INSTRUMENT ACCURACY SATISFIED The Barton Lot 1 transmitters are used only for wide range pressure, pressurizer level and steam generator level-functions at FNP. Therefore, the +14 percent error noted in the report for narrow range pressure does not require evaluation. The results provided in NS-TMA-1950 for the functions noted are further supported by the supplemental testing reported in NS-TMA-2120, which confirms the (m~/g conclusions derived from the threshold tests.

B. CRITERI?. REGARDING RADIATION SATISFIED The pressurizer pressure application for reactor trip signal generation only requires an operating time of 5 minutes post accident. The radiation test reported in Appendix C of WCAP 8541 demonstrates the ability of four out of five 4-20 MA transmitters to perform up to a TID of 2.2 x 10' rads.
The one failure occurred at 8.6 x 10' rads. Even if this is not considered a random failure, all of these units' performance far exceeded the 5-minute requirement of approximately 2 x 105 rads. This certainly demonstrates that these units do not contain materials that are susceptible to radiation damage. The materials, including the seals, were selected by Foxboro for high radiation service.
C. CRITERIA REGARDING TEST SEQUENCE SATISFIED The DOR Guidelines indicate that test sequence is not required if susceptible materials are not present. Since there exist no problems with radiation in Clarification "B,"
it was concluded that susceptible materials to aging did not exist in the FNP pressure transmitters.

B. CRITERIA REGARDING RADIATION SATISFIED Westinghouse Qualification Test Report WCAP 9157 documented a total dose of 4 x 10' rads in the Foxboro transmitter irradiation test. APC's July 30, 1980, submittal,
" Joseph M. Farley Nuclear Plant - Unit 1 Response to the NRC I.E. Bulletin 79-OlB," provided a SCEW sheet which identified the radiation specification for these Foxboro flow transmitters to be 5 x 10' rads. The SCEW sheet was in error because it presented a higher radiation dose than would be expected for these transmitters. The transmitters, which are required to perform their intended function during HELB accident conditions, would reveive a total of 3.9 x 10' rads over a 40-year period considering norma {
(-)
(_/
and accident conditions as documented in WCAP-8587. Since these transmitters would not be exposed to a total radiation dose in excess of that documented in the Westinghouse qualification test report, the FNP transmitters are qualified.
C. CRITERIA REGARDING INSTRUMENT ACCURACY SAT 1SFIED The test documented in WCAP-9157 demonstrated that the unit performed its intended safety function.
D. TEST DURATION MARGIN SATISFIED The test was not intended to demonstrate a 1-hour margin, but only to show that the unit would survive long enough to perform its safety function. Margins for trip function requirements are contained in the HELB envelopes, which encompass a full spectrum of break sizes and are also justified by the fact that the signal generated by the sensor is " locked-in" by the protection system and will not reset should the sensor fail after the dasignated trip time requirement. This evaluation also considers what consequences failure of the device would have on the operator and the mitigation of the event.

B. CRITERIA REGARDING SUBMERGENCE SATISFIED NRC Position:
(DOR GUIDELINES SECTION 4.1, SUB-ITEM 3; AND SECTION 4.3.2, SUB-ITEM 3)
Equipment submergence (inside or outside containment) should be addressed where the possibility exists that submergence of equipment may result from HELBs or other postulated occurrences. Supplement 2 to IE Bulletin 79-OlB (12) provides the following additional criterion: If the equipment satisfies the guidance and other requirements of the DOR Guidelines or NUREG-0588 for the LOCA and HELB accidents, and the licensee demonstrates that its failure will not adversely affect any safety-related function or mislead the operator after submergence, the equipment can be considered exempt from the submergence position of the qualification requirements.
APC Response:
With the Qualified Life clarification provided in part A above, the NAMCO EA180 limit switches located inside
{')h
' containment satisfy the guidance and other requirements of
. EQUIPMENT ITEM NO. 33 the DOR Guidelines or NUREG-0588 for the-LOCA and HELB accidents.
Appendix 4,Section II.C, of " Joseph M. Farley Nuclear Plant - Unit 1 Response to NRC I.E. Bulletin 79-01B," and was forwarded to the NRC on August 25, 1981, demonstrated that submergence of limit switches (N1E21ZS8149A, B, C), (Q1E21ZS8808AB, BB, CB), and (Q1G21ZS3376; NIG21ZS1003B) will not adversely af fect any safety-related function.
In addition, Alabama Power Company has determined that these limit switches would perform their intended function prior to becoming submerged and any circuit shorts that could occur would not mislead the operator. Therefore, these limit switches should be considered exempt from the submergence portion of the qualification requirements.
Limit switches (Q1E12ZS3999A, B) are located in the reactor cavity and will not be subject to submergence. Therefore, these limit switches should also be considered exempt from the submergence position of the qualification requirements.

B. CRITERIA REGARDING SUBMERGENCE SATISFIED In Revision 6 to APC's July 30, 1980 submittal, " Joseph M.
Farley Nuclear Plant - Unit 1 Response to the NRC I.E.
Bulletin 79-OlB," which was forwarded to the NRC dated December 28, 1981, it was stated that these pressure transmitters would be relocated above the flood level during the third refueling outage. The subject transmitters were relocated above the flood level during the third refueling outage as stated in referenced submittal.
C. CRITERIA REGARDING INSTRUMENT ACCURACY SATISFIED The Barton Lot 1 transmitters are used only for wide range pressure, pressurizer level, and steam generator level functions at Farley. Therefore, the +14 percent error noted in the report for narrow range pressure does not require evaluation. The results provided in NS-TMA-1950 for the rg functions noted are further supported by the supplemental
(_) testing reported in NS-TMA-2120, which confirms the conclusions derived from the threshold tests.

APC Response:
The qualified life of the NAMCO EA180 limit switches located in harsh environments outside the containment has been determined based on type testing, material analysis using Arrhenius Methodology, and/or operating experience to be 18 years. An Environmental Qualification Administrative Program is being implemented which includes for the NAMCO EA180 limit switches a preventive maintenance / surveillance program with equipment and component refurbishment and/or replacement based on known susceptibility to aging degradation, the results of inspections, and manufacturers recommendations.

O sectioa C Justification for Continued Operation It is the judgement of Alabama Power Company that all equipment required to achieve a safe shutdown condition at Farley Nuclear Plant is qualified and justification for continued operation for equipment ,
items in NRC categories I.B., II. A. and II.B. is not necessary.
The information provided in Section B should resolve all NRC concerns related to environmental qualification of FNP equipment except for Victoreen Radiation Detectors. The only outstanding action item related to Victoreen Radiation Detectors is the installation of a' watertight fitting.
These detectors were installed as an enhancement to the radiation monitoring system to satisfy the requirements of NUREG-0737 and would be used to detect a radiation release due to a potential breach of the reactor coolant pressure boundary.
-The installation of the water tight fitting is currently in progress and will be completed during the current ref ueling outage. Upon completion of this modification the FNP Victoreen Radiation Detectors will be fully qualified.
