2.0 TEST PLAN Environmental cycling was performed on the Source and Intermediate Range Excore Neutron Detector Assembly in the Westinghouse Industrial and Government Tube Division (WIGTD)' temperature and humidity chamber in Horseheads, New York. The portion of the chamber used.for this test was a 20 foot length of 8 inch schedule 40 stainless steel pipc. The ele-vated temperature was generated 'by heated oil. High humidity was achieved by adding water to the chamber and pressure was ad.iusted at dwell times using a high pressure air source. Reference 1 provides a more detailed description of the test facility.
Seismic tests were performed at the Westinghouse Advanced Energy Systerns Division (WAESD) Seismic Laboratory on the 8'x 8' Magnesium Table.

. WESTINGHOUSE CLASS 3 2.10.2 Equipmen Tested The testing was performed on type WL-23821 Source and Intermediate Range Detector Assembly, WL-23821, S/N-815201.
2.10.3 Features Demonstrated by the Test Testing demonstrated that the unit would function bu. during and after abnorcal service conditions. Reference 1 summar.. 'he results of environmental cycling.
The single design basis event considered is a seismic event since the detectors are not required to function during or after a HELB. The unit functioned properly before and after seismic excitation. Reference 1 summarizes the results of seismic tests. At the end of the test sequence, electrical tests, disa::sembly and inspection resulted in find-ing no significant degradation.-
The Source and Intermediate Range Detectors are not required to perform .
a function during or after a HELB. It is expected that the detectors would initially short when exposed to the HE'LB and eventually open. The shorting would be of no concern since the high voltage power supplies are current. limited and are not exposed to the HELB. Erratic _ operation may occur as some components may be damaged. The intermediate range compensating power supply is isolated from primary power by a transformer so failures in this area would be of no concern.
2.10.4 Test Procedures A number of performance measurements (known as acceptance tests i.e.,
resistances, leakage currents, capacitances, gamma sensitivity, gama compensation, neutron sensitivity, background test and thermal neutron sensitivity check) were carried out by Westinghouse IGTD during normal l- conditions; further detail is given in Reference 1. Simulated service conditions consisting of sixteen 80 to 135*F cycles, four 135' to 200*F (abnormal) cycles, seismic excitation and post environmental tests are 1

. WESTINGHOUSE CLASS'3
- . l all o tli ed in test procedures contained in Reference 1. The purpose l I
of the environmental cycling was to simulate the conditions experienced during 5 years of continuous service. Seismic testing consisted of a resonance search, five OBE's and four SSE's. The post seismic test procedure consisted of a repeat of electrical acceptance tests and disassembly and inspection as described in Reference 1.
2.10.5 Test Data and Accuracy '
All electrical test results obtained before and after each test sequence remained within specified acceptance limits. The Detector sensitivities were not expe:ted to change from the beginning to the end of the test program. Any variation within +5% were considered to be measurement error. The sensitivities of the proportional counter and compensated sonization chamber after the seismic event were within 5% (which is measurement error) of the original sensitivity measurements. Test data met the normai acceptance Ifmits except for a portion during envi-ronmental cycling that was not considered to have a significant effect upon operation. A su.m ry of test data and accuracy. discussion can be .
found in Reference 1. , ,
2.10.6 Conclusions The results of environmental cycling and seismic testing described herein and reported in Reference 1, demonstrate the qualification of the Source and Intermediate Range Excore Neutron Detector Assembly employing the practices recomended by Regulatory Guide 1.89 and 1.100.

SNUPPS Interim Justification Position for the Seismic Qualification of the TC/CCM Systen (ESE-56A) e l
Background
The SNUPPS Thermocouple / Core Cooling Monitor System (TC/CCM) comprises two identical microprocessor-based monitoring assemblies or trains, each monitoring various analog and digital inputs, performing calculations using the information obtained from the inputs, and actuating caution or alarm outputs when preset trip points are exceeded. Each provides relay contact outputs for caution and alarm conditions, along with serial data outputs, to j the Technical Support Center (TSC), digital and analog recorders, and a remote digital display. The local and remote control panels have lamps that indicate POWER on; processor RUN, STOP; and system status (NORMAL, CAUTION, and ALARM) conditions. Switches on both the local and remote control panels reset the central processing unit (CPU) and acknowledge alarm or caution outputs. In addition, there are controls for selecting display format and content and, on -
the local control panel, for testing the system, adjusting setpoints for cautions and alarms, and activating or deactivating selected inputs. ,' '
The upper six ifnes of the remote digital display unit are allocated for .
thermocouple, RTD and pressure data, and the lower two lines are f,or, core cooling data. Alarm and caution outputs and indications are shared by both functions. If one alarm or caution is ictive and a second alarm or caution condition occurs, the appropriate relay will cycle and, if the plant annunciator system has the capability, alarm or caution signals will be reflashed to ind1cate the new alarm or caution condition.
The TC/CCM enables the plant operator to activate necessary manual safety functions following a Condition II, III, or IV event. These safety measures include providing information needed to maintain. the plant in a safe shutdown
- condition, or to proceed to a cold shutdown, consistent with the Technical Specification limits. .
Previous Environmental Testing (This equipment is located in mild environment areas of the SNUPPS plants)
The TC/CCM system has been subjected to the complete IEEE 323-1974 and IEEE 344-1975 qualification testing. The TC/CCM system successfully passed -
temperature and humidity testing and seismic testing. Aging simulation is I
l ,
L
addressed in a separate program, as described by Subprogram C of Appendix B to .
~
WCAP 8587, currently in progress.
The specific parameters of tests already conducted are as listed below:
Temperature / Humidity Testing:' Two twelve hour cycles at 120*F, 35% RH Two twelve hour cycles at 82*F, 95% RH Seismic Testing: Tested per IEEE 344-1975 requirementswithoperabblity demonstrated before and after each SSE.
TC/CCM Cabinet Electronics:
Current Status: Data is being reviewed; accuracies are being calculated.
Repeatability of the data is acceptable. During seismic - -
testing the requirement was for all equipment to function properly before and after each SSE. '
Remote Digital Display: (See ESE-46A) 4 No failures occurred during temperature / humidity testing and seismic SSE test runs in positions 1 and 2. During position 3, a vertical column on the plasma display blanked out and another vertical column became intermittent. During position 4, ar,other vertical column blanked out. This condition continued to exist after the testing had ended and also during subsequent operation of the display.
The display was removed from its panel and sent to the original manufacturer for checkout, test and evaluation. Upon energizing the disp. lay the manufacturer reported that the display operated properly with all columns working. The display was then disassembled in an attempt to identify a cause ,
for its intermittent operation. They concluded that certain vibration modes cause fretting of the edge connector contacts and board edge fingers. The fretting produces microscopic particles of oxidized material that act as.a
. 6
l l

! insulator, thereby causing intermittent or open circuits. Based on the nature - ;
of the failure which occurred during the third SSE, the testing provides sufficient evidence that the plasma display vould perform properly during one SSE. However, to provide additional margin, the manufacturer is developing a lubricant / oxidation inhibitor which would minimize the fretting and also minimize any fretted material from becoming an insulator. If appropriate, this inhibitor will be incorporated into the SNUPPS desig~n.
One additional problem occurred with the PS-2 power supply. Its performance was satisfactory during all seismic testing, however, its output became intermittent at high temperatures during the temperature testing. Further i
testing is scheduled; however, for SNUPPS this system is in the control room which has Class 1E HVAC and will not experience an abnormal environment.
TC/CCit Digital Printer (See ESE-46B) l No failures occurred during testing. The printer functioned properly l throughout with acceptable legibility and accuracy. .
Test Schedule ,

Testing is scheduled for completion, including the submission of the test report by July, 1984.
