! TITLE: MAINTENANCE REQUIREMENTS FOR MAINTAINING THE ENVIRONMENTAL l QUALIFICATION OF THE EXO-SENSORS, INC. HYDRUGEN ANALYZER
1.0 PURPOSE
i This Field Directive transmits to the Salem Generating Station the requirements for maintaining the qualified status of the Exo-Sensors Hydrogen Analyzers.
2.0 SCOPE
This document applies to the required hydrogen analyzers. Both Units 1 and 2 possess an Exo-Sensors hydrogen analyzer installed in each containment.
3.0 REFERENCES
3.1 Containment Hydrogen Analyzer System - Operation and Maintenance Manual - Exo-Sensors, Inc.
PSBP 174275
4.0 DISCUSSION
The purpose of the hydrogen analyzers is to provide an indication of hydrogen concentration in the containment.
The Hydrogen Analyzer System consist.s of hydrogen sensor
- calibration assemblies mounted in containment and a microprocessor control assembly located in the Equipment Room.
The Exo-Sensor Hydrogen Analyzer utilizes hydrogen partial l
pressure and containment total pressure to compute the hydrogen
- concentration in containment. Information from the temperature transducer is used by the microprocessor for temperature compensation.
Hydrogen Partial Pressure Volume % Hydrogen = x 100 Total Containment Pressure To maintain their qualified status, specific scheduled 4 maintenance must be performed. What follows is a summary of the required maintenance activities and the frequency with which they shall be performed:
- 1) Every 90 days (or 30 days post-LOCA) the automatic calibration cycle shall be checked by performing the hydrogen sensor 2-point check, and the single point check
! for the temperature and pressure sensors.

S-C- A910-CFD- 0 3 28-R0 Date: 7/15/85
- 2) Every 12 months, the signal conditioner status shall be checked by a) measuring the bridge voltages for the transducers and RTD's, b) updating the calibration factor, and c) verifying the system alarm.
- 3) Every 24 months the calibration gas supply shall be replenished. This involves recharging the calibration gas cylinders, checking the regulator settings, and checking the supply manifolds, fittings and valves for leakage.
- 4) Every 36 months, the hydrogen sensors shall be replaced; and the RTD's and pressure transducers shall be checked.
This involves performing a 2-point calibration check of each, and updating the calibration factors, as necessary.
- 5) Every 10 years, the calibration assemblies shall be refurbished by replacing the following components:
a) calibration pistons and caps b) regulator diaphragms c) bottle valve stem seals d) pressure transducers e) RTD's f) solenoid coils The procedures to perform these activites are all clearly outlined in Section 5 of the vendor's manual ( Re f . 3.1 ) .
Reference 3.1 includes the diagrams, schematics, descriptions of the analyzer and vendors information of all replacements parts necessary to perform the required maintenance with relative ease.
5.0 CONCLUSION
/ RECOMMENDATION:
Section 5 of Ref. 3.1 gives a clear, step-by-step set of procedures to accomplish the necessary maintenance activites.
Adhering to the information and procedures of this reference will ensure the continued qualification of the Exo-Sensors Hydrogen Analyzers in Salem Unit 1 and 2.

The qualification test program, including any engoing programs which follow, will establish the qualified life of the analyzer system and its major ccmponents. Routine maintenance and replacement procedures will thus be defined 1 l
to assure the proper operation of equipment throughout the qualified life.
Based upon consideration of environmental conditions, material and performance evaluations and baseline data for components, the age-related failure mechanisms will be estimated for the hydrogen analyzer system. Those components and subassemblies susceptible to aging (e.g. , sensor assembly) '
will be artificially aged to an end-of-life condition by .
operation at stress conditions. For the sensor, operation I at temperatures higher than the normal pre-event levels will be sufficient to provide accelerated aging. Cataloged data ,
from various sources will be used to establish aging criteria . I for other components as well. '
For purposes of establishing ground rules for aging, l a,n environmental profile has been assumed. As a result of the sharing electronics between PINGP-1 and PINGP-2, it is anticipated that the data systems will be continuously l
" powered up", and that operation for 100 days after accident onset is required. The hydrogen sensors and associated calibration equipment will see continuous operation at normal containment conditions.
A typical duty cycle for the electronics is assumed to be as follows: @
Operation at 72-75*F;i355, days per year Operation at 105'F; 10 days per year As a result of the requirement totoperate continuously, because of the unique nature _of the tims shared configuration, it w'ill not be faisib'le tC perform;a full pri~ aging, there-fore, an ' ongoing ' aging procedure 1will' be implemented.
22 -
The electronics shall be subjected to brief perieds of operation at 50*C,(2 periods of 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> each) by the manu-facturer. Operation of the electronics after this initial screening will be for as long a period as practical prior to seismic simulation. Operation through seismic, and subsequent accident simulation will then be performed with a minimum of 100 days of post accident operation accumulated.
- Evaluation of system performance at this time will verify satisfactory performance to th5t date. Operation of the system will continue:and. additional performance date g will be accumulated. Techniques and validity of accelerated '
aging processes will again be evaluated and utilized if feasible. Aging may include another seismic simulation at .
this time.
This approach to demonstrating qualified life is in ~
general accord with the options afforded by IEEE Std. 381- .
1977. The post-accident aging by operation is deemed valid for the electronics since the DBE adds no appreciable stress to this equipment which is located in the " Bus Room".
The basis for in-contain m at equipment is that routine f I
replacement of the sensor be accomplished at 18 months, at which time the support equipment may be inspected and/or maintained. Assuming continuous duty on the reactor for this period, the temperature will remain at 140*F for the {
f entire period.
4.0 SEISMIC SIMULATION The seismic qualification of the hydrogen analyzer is
- intended to demonstrate that it will function.during and after the time when it is-subjected to the-forces-resulting f 3. [from a safe shutdown ea$thquakai-~(NSE)~ai~fter ~it-is shown' -

l I. : 1.3 TEST SEQUENCE l In accord witn~ tne recu:rements for cualification of equimment fer Nuclear Safety Relatec use, the cressure transducer anc RTD were excosed,to a series of envtronments which included: Acceincated thermal aging cycle, Exposure to gamma radiation,
- Seismic test, LCCA test.
Between each of the environmental exposures,.a test _was perf5cmed - to verify that performance of the component had not degraded. In
--- --addition the components were cowered 'and - ~" operating during_t,ne_seis- = ._... - mic.and LOCA -tests. - - _ . . .- .
_1. 4 ' ACCIDENT PROFILE The test profile (Figure 1-2) is configured to provide test tem-peratures above tne credicted accident crofile (Figure 1-1) to reduce actual test time. The basis for cetermining the ecuivalent test oeriod are the thermal acceleration relationships presented in the Arrnenius ecuations which relate activation energy (a reaction rate coefficient) with the temperature differences between actual test levels and specification levels, t The activation energy defines the rate at which materials react with their environment. For tne analyzer system, the lowest ac-tivation energy found ts 0.78 ev. Using actual temperatures and tne Arrhenius ecuations the ecutvalent test times are oetermined. The SCE requirements for 116 days of equivalent operation were achieved at the 29th day of testing. The LOCA test log in Appendix B shows the detailed cally corrected tabulation. The first 24 days of test time was accumulated at the Wyle Laboratories Norco Test Facility. The report by Wyle is included in its entirety in Apoendix D. At this time the test article was moved to the chamber facilities at Exo Sensors wnere the test was concluced after 56 days of .est time. During the test period. hvorogen was added to the test chamber to verify analyzer performance. These verification tests were per-formed on a weekly basis. System calterations were cerformed at 30 day intervals to re-align analvter performance. Out of tolerance readings occurred immediately following the LOCA transient, at wnich time a caltoratton was cerformed. Otner cal: orations at 30 days were sufficient tc maintain system accuracy. - ~~

l 2.2 AGING The major aspects of,agtng for the in-containment hydrogen analy:er components revolve arounc tnree constoerations, namely accelerated enorm41 agtng, accelerated operattonal aging, anc radiation ex-posure. Tne in-contatnment components are cefined in Exo Sensors crawing numeer 195D005. Hycrogen Sensor Calibration Assemoly. The bants for defining the aging environments included the specifica-tion recuirements for temoerature and ractation, and the coera-tional cycling of the inotvioual components antteipated over the i life of the comoonent. The pressure transducer anc RTD aging status at the time of tne loca test are shown in Taele 2-2. l TABLE 2-2 IN CONTAINMENT COMPONENT AGING
SUMMARY
EXO SENSORS DRAWING NO. 1980002, REV. B l Component Name l Ecuivalent Age Radiation Level i Pressure Transducer 24.1 years l 60 Megarads . RTD 24.1 years 60 Megarads i 2.2.1 Thermal Acino 1 , The masts for thermally acceterating the aging of components by controlled exoosure to temperatures aoove the normal opera-tional levels is presented in the 1980 EPRI Report, "A Review of Ecuipment Aging Theory and Technology." Section 4, Theories of Aging, presents the rationale bentnd the two major industry practices for determining accelerated aging ! conditions; namely the Arrhenius Model and the 10 cegree C rule (whien is a special. simplified version of the Arrhenius Model). l l The Arrhenius Model aging is based on estimating material stress over a limited range of conditions and a i ceterioration or failure, based on the physical or chemi-i cal processes taking place. The stress factor for non-metallic materials used in these relationsnios is the Ac-tivation Energy of tne material. The general form of the 1 ocuations acclied to thermal aging is as follows: 4 Arenenius Model: L=BE*'** (Ti-7.1/10 10 degree C: aq= C2 i where L = time to reach a specified endocint or
, lifettme. l > B = Constant (usually determined experimentally).

These levels of 40-60 megaraos of gamma exceed the specifica-tson levels of the total beta and gamma spectrum ex-Docted, and serve to provice a significant margin for operation. 2.3 LOCA SIMULATION i The LOCA simulation is described in detail in Aopendix C. in the Wyle Test Report. Analycer evaluation during tnat period showed the following cerformances uoan stanili:ation of chamoer temperature at 270*F and 39 osig, hydrogen was adoeo to the chamoer for verification of analy:er per-formance. Performance verification tests were performed showing overall analyzer peaformance for the 60 day period remained within specified limits of +/- 0.2% of actual hydrogen concentration sn-
- dtcating all components were within operational specifications.
