SAFETY EVALUATION CONCLUSIONS:
%e proposed change, test or experiment:
- 1. (X) Does ht ( ) Does increase the probability of occurrence of conse-quences of an accident or malfunction of equipment important to safety previously evaluated in the FSAR.
- 2. (X) Does Not ( ) Does increase the probability for accident or malfunction of a dif ferent type than any evaluated previously in the FSAR.
- 3. (X) Does Not ( ) Does decrease the margin of safety as defined in the basis for any technical specification.
- 4. Se proposed change will increase the margin of safety.
BASIS FOR SAFETY EVALUATION CONCLUSIONS:
- a. me replacement analog transmitters and trip units are seismically {
and environmentally qualified for the intended use. te analog trip system is also inherently less susceptible to undetected primary sensor element drif t due to utiliza o o a e in each si nal -
V 's O . w g g
- b. S e trip units are designed with individual pows ation ci
@ [e so that the main power supply voltages need not ely O regulated. Redundant power for the ECCS analog s provided in 5 each divisional panel from both a safety-related 120VAC source and a W A 25VDC source. In addition, two 24VDC instrument power supplies are j
in g provided in each panel with their outputs paralleled. @us, each j g divisional analog system will remain functional in the event of loss Q
o of one input power source and/or one instrtament power supply. Power supply failure is annunciated.

- d. We functions o,f some of the existing mechanical switches have been combined in the analog system. te Pilgrim FSAR Sections 7. 2, 7.3 and 7.4 Design Bases were met in combining these sensors. Wese combinations do not decrease the margin of safety since they were performed utilizing the following criteria:
- 1) Instrumentation utilizing common process taps were combined, l
maintaining the required ECCS division /RPS channel separation.
- 2) Annunciation, non-Class 1E indication and non-safety-related control trips were combined with BCCS instrismentation utilizing appropriate isolation between safety-related and non-safety-related logic / signals. .
- e. We margin of safety is increased on the basis of verified environ- ,
mental qualification of the analog trip system components, a reduc- )
tion of time the RPS is in a half-scram condition to functionally test or calibrate components, elimination of likelihood of instrument valving errors and instrument testing-related scrams, reduction of (
undetected sensor drif t, reduction of time required to functionally 1 test or calibrate safety trip points, and incorp> ration of separation ,
requirements in compliance with 10CFR50, appendix R. {
(
- f. We design criteria of this system is consistant with the analog trip I system presented in General Electric Q)mpany's 11 censing '1bpical Report NEDO-21617-A, which has already received a positive Safety i Evaluation by the Nuclear Regulatory Cbasission.
- g. %e combination of ECCS functions and the combination of RPS f unctions (see Table A.2-1 of the Design marrative) in the Analog Trip system is made possible because the output of each of the new transmitters is an analog signal which is fed to individual and isolatable slave trip units via the master trip units. te existing mechanical switches could not employ this master / slave principle since it would require interlocking mechanical linkages.

7.2A.2.1 General System Description [
The Analog Trip System (ATS) is a multi-channel signal conditioning system with built-in calibration capabilities. It provides highly accurate, easily calibrated, trip output signals for processes remotely monitored by 4-20 ma transmitters. The trip unit output signal drive can be used as an input to relays for annunciator interface or an external load of up to 12 amp at 24 volts. An auxiliary 1-5 volt DC analog output is available for driving external monitoring or recording .
equipment.
An additional 1-5 volt DC analog output is available for operation of up to seven slave trip units to provide additional trip points for a single input sensor. The trip units are equipped with a two-position logic invert switch ISSUED FOR internal to the unit, allowing for selection of either high trip or low trip status. Th is allows the trip relays to be either deenergized or energized during normal operation.

Individ*al u cystem requirements dictate positioning of the logic switch for proper operation. A s implified depiction of the trip system is shown in Figure 7.2A.2-1.
The system is an electronic trip unit system which is testable in place. It incorporates a readout for each sensing loop that continuously displays the parameter being monitored during operation of the plant. In
~
addition, the test current is displayed numerically with high resolution to achieve setpoint accuracy requirements imposed by system specifications.
~
System response times are based on a f ixed time constant (63%) at 100*F as follows: 0.5 seconds for reactor water level transmitters LT-263-72A, B, C, D and 0.2 seconds for all other transmitters installed as part of the analog trip system.
Interface displays are provided to indicate status of trip system " key" functions, such as logic trip, transmitter current loop failure, card out of file, power loss, and trip unit inoperative status.
Power supplies for the Analog Trip System instrument power consist of two Class 1E 24VDC qualified power supplies per Analog Trip Cabinet. For redundancy the power supplies in each cabinet have their outputs connected in parallel with each other and each power supply will receive its primary power f rom one of two sourcos, ESS 120VAC or 125VDC from its proper power division.
7.2A.2.2 Transmitters I.
Environmentally-qualif ied Rosemount .8 k153 Series B (output Code R) nuclear grade tran mi ters have been installed as the sensing devices, providing the input signals to the master trip units. These transmitters provide precision pressure measurements in nuclear '
applications requiring reliable performance and safety
. over an extended service life. These transmitters were tested per IEEE 323-1974 and IEEE 344-1975 to ISSUED FOR radiation levels of 22 megarads TID gamma radiation, seismic levels of 4 g's, and for steam-pressure performance.
Direct electronic sensing with the completely sealed delta-CELL" capacitance sensing element eliminates

like manner to the other side of the sensing diaphragm. Displacement of the sensing diaphragm, a maximum motion of 0.004 inches (0.1mm), is proportional to the pressure dif ferential across it.
The position of the sensing diaphragm is detected by capacitor plates on both sides "of the sensing diaphragm. Differential capacitance between the sensir- diaphragm and the capacitor plates is conver ced electronically to a 2-wire, 4-20 mADC s ig nal.
Output code. R amplifier design incorporates an improved circuit board material ( rated for higher
- operating temperatures) with a view towards improv ing performance under radiation t 7.2A.2.3 Master Trip Unit t 12 The Fbsemount Model 710DU master triptundt"i a plug-in circuit board assembly designed to accept a 4-20 mA signal from the remote transmitter. The master trip unit produces a trip output signal when the input signal passes through a preset trip point and a gross f ailure signal when the input signal is outside preset high or low limits. See Figure 7.2A.2-2 for the master trip unit functional block diagram.
In addition to trip and gross failure outputs, the master trip unit also produces two buf fered analog output voltages of 1-5vdc proportional to the input signal of 4-20ma. The electronic buf fer (an integral part of the comparator) protects the trip unit from a back-surge of power due to short-circuits, etc. One analog output is used to drive up to seven slave trip units, establishing additional trip points for a single input s ig na l . The second analog output is used to drive external recording or monitoring equipment.
Master trip units have a trip point adjustment potentiometer on the f ront panel, as well as an analog ,
meter displaying the input signal, two light-emitting diodes indicating trip and gross failure conditions, a gross failure reset button, and test jacks to monitor ISSUED FOR the input signal and the auxiliary analog output signal.
The circuit board for a master trip unit includes adj us tnen ts for high and low gross failures, trip i reset differential, trip output logic and trip status LED logic. In addition, the 4-20 mA input trip unit
, CONSTRUCTION has an adjustment for the frequency response of the auxiliary output s ig nal .

The circuit board of a master trip unit with RTD input also includes potentiometers for adjusting the zero, span, and linearity of the buf f ered signal.
L l 7.2A.2.4 Slave Trip Unit The Rosemount Model 710DU slave trip units in the I analog trip / calibration system 'are used to provide i
additional setpoints . for a common transmitter. The ,
l slave trip units receive a buf fered 0-10 VDC (0-1004) {
signal (calibrated from 1 to 5 VDC) proportional to I the input signal from a master trip unit. The slave trip units produce a. trip output signal when the input signal passes through a preset _ trip point, and a gross f ailure signal when the input signal is outside preset high or low limits.
The front panel' of each slave trip unit. includes a trip point adjustment potentiometer, LED's indicating trip, and gross f ailure outputs, a gross failure reset button, and a test jack to measure the input signal from the master trip unit. Adjustments for high and low gross failure levels, trip reset dif ferential, trip output logic, and trip status output / LED logic are contained on the slave units circuit board.
Slave trip units are 'never directly cosa.scted to any external signal source andedp t emerate analog output signals.

The nominal output of the trip units is 24 VDC for logic 1 and 0 VDC for logic 0. An Agastat EGP-B-002 relay is required to provide logic previously supplied -
by the mechanical switch. Each relay is provided with four single pole double throw contacts and consumes less than 6 watts power per relay coil. The design life is 5 x 105 mechanical operations which exceeds ISSUED FOR expected usage in 40 years of operation. Contact nominal voltage and current ratings are: 10 amps at 120 VAC, 1.5 amps at 125 VDC, 0.2 amps at 250 VDC, and 10 amps at 24 VDC.
Each master or slave trip unit is capable of supplying trip relay loads up to 1 amp at nominal 24 VDC.
CONSTRUCT lON contacts from the relays provide necessary contacts for logic function of the process inputs. Master and slave trip units are equipped with diode output

7.2A.2.7 Calibration Unit Q
V gy Lg i In-place calibration of all master and slave trip units will be possible by use of the Rosemount calibration unit which produces a calibrated command signal, calibration currents, and a calibration status signal. Calibration of any channel is initiated by the " calibrate" command signal. The signal replaces the input signal to the master trip unit and causes a gross failure output. The calibration current supplied by the calibration unit is made up of independently adjustable stable and transient current. The normal use cf the stable current is for verification of the calibration point of any given channel and to check analog signals of the master trip units. The transient current source is used to provide a step current input into a selected channel such that the response time of that channel can be determined from the trip unit input to any point downstream in the logic to and including the final element. The transient current can also be used to check high and low gross failure points.
7.2A.2.8 Readout Assembly The Rosemount readout assembly is a portable ISSUED FOR measurement and display device which is inse rted into the front of the calibration unit and may be transferred to other calibration units. The readout assembly contains two digital displays which measure and display calibration with a 0.01 mA resolution.
The lower display, designated the calibration current
' CONSTRUCTION display, continuously shows the total calibration current generated by the calibration unit. The 'pper display, designated the trip current display, tracks the stable calibration current shown on the lower display until the trip output of the master or slave trip unit being calibrated changes status. The XBE-09-602 7.2A.8 Rev ision 0
l calibration current reading at that point is la tched l
on the trip current display by the trip status signal from the trip unit. The portability of the device provides for ease of readout assembly calibration with only one readout assembly required for all calibration equipment in the plant. The readout assembly is commonly calibrated with a laboratory bench standard to con f irm its accuracy. Using a single readout assembly assures maximum precision and consistent process trip setpoints.
7.2A.2.9 Trip Unit Card File Rack
-Master and slave trip units may be arranged in any order in the card file rack. Twelve slots are available for trip units with the thirteenth slot being used for the calibration unit. The calibration unit is equipped with a twelve position selector switch for calibration of individual trip units. When an individual trip unit is being calibrated, the transmitter and logic action can be completely simulated by the calibration unit. For this reason, logic pairs of one ECCS division may be placed in the same card file rack. Only one trip unit may be ,
functionally tested at a time; therefore, it is impossible to accidentally activate a safety action while routinely checking setpoint trip or individual logic chain permissives.
In the RPS system, cards are arranged in files by l individual logic trains because of the "deenergize-to- !
actuate" log ic . This requires each logic train to be '
in a separate cabinet. For example, A and C cannot be in the same cabinet, becau se ,a ,.s iqq l trr F ' %
could cause a potential f ailure td s 6 ugh A s e and B could be in the same cdbine*t' from a s je f ailure standpoint, separation of powe as them to be in separate cabinets. Unlike th stem, it is possible to induce scram by using the calibration unit; however, to achieve this condition ,
wauld require the technician to attempt to calibrate devices in both power divisions simultaneously while ignoring the annunciations.
All units in the trip calibration system plug into the card f ile. Any combination of master and slave trip units may be inserted into twelve slots of the rack with a double slot used for the calibration unit. The card file is wired for calibration and mounts in a
- "d*"d "i"*'**" I" h * "P" '* ** "*""* *'*
. CONSTRUCTION typically arranged so that only one channel of the l system may be tested or calibrated at the same time.

7.2A.3 SYSTEM INTERCONNECTIONS AND SEPARATION The original plant separation criteria have been followed in routing of new cables and the location of new equipment. All transmitters, with the exception of twelve local transmitters which are mounted on new supports, are mounted on existing instrument racks in the same approximate location as the devices which they replaced.
7.2A.4 SINGLE FAILURE AND CHANNEL INDEPENDENCE' CRITERIA The single-failure and channel independence criteria are met by the unchanged multichannel logic already inherent in the base plant de s ig n , In addition, each RPS channel and ECCS power division has its trip unit system housed in a separate trip cabinet. This assures that a failure of the transmitters or trip units in the ECCS does not affect the RPS and v ice-versa.
7.2A.5 SURVEILLANCE / TEST INTERVALS The analog trip system modification and associated instruments-tion upgrade requires changes to the surveillance requirements as noted in the Technical Specifications. The recommended surveillance / test intervals, based on NEDO-21617-A, is once per operating cycle for each transmitter and one channel (or division) per month, perfectly staggered, for the trip units.

Routing of new cables which cannot be routed in existing conduits will use the new duct run being added for Appendix R where practical.
The raceway routing will take into consideration the ease of constructibility. Where practical, the raceways, junction boxes and other components will be routed less than 8 feet above the floor to minimize scaf folding. In areas where the raceways run vertically, it has been determined that there is suf ficient existing superstructure to m]{imize !
- the use of scaf folding. - <4 .
- J l Raceway installation during plant operation'will be l- confined to the reactor building, radw5ste building, and the cable spreading room. The turdine building will not be accessible for conduit installation under the main floor ( El. 51'-0") during plNntl operation.
The new ECCS panels C2233A and C2233B and associated raceways may be installed during plant peration.
The raceway routing in the reactor buil i h will entail the use of new and (poss ibly ) existing supports (latest seismic design) as observed in the f ield . The turbine building, radwaste building and cable spreading room will require virtually all new l
supports, except for a few existing supports tha,t ,

B. BENEFIT - EFFECT ANALYSIS The iniitallation of an Analog Trip System is required to be installed at Pilgrim Nuclear Power Station Unit il to meet the NRC's Environmental Qualification rule and to improve plant operation. Many safety-related signal transmitters are located in harsh environments that require replacement by qualifled Class 1E Transmitters. An improved instypentation >a system will provide a cost-beneficial remedy for exde,ssive undetected instrument setpoint drift, high surveillance testing expenditures, and excessive half scram con 4(tions
~ '
during calibration and testing. ..
~>-
To satisfy these requirements and to provide a 'Egntralized ~
location for monitoring system status, an analog; transmitter /
trip unit system will be installed at PNPS. This' system will consist of locally mounted analog transmitters, each sending a calibrated 4-20 mA signal to a remote panel cont,aining ..o trip units adjustable to trip at the required signal leyel. The system includes ins t rumentat ion in the Reactor Protection System ( RPS) , N....W.M(Yk. _'_'.'.*- *U*

This modification was a'pproved for licensing by the NRC in -
1978 and is the subject of the General Electric Company Topical Report NEDO-21617-A. This topical report is acceptable to the NRC as a reference in license applications by utilities for installation of a system based on the NEDO docum'ent design.

- Rev. 0 Sht. 14 of 70 The Analog Trip System (ATS) is designed to replace direct acting pressure dnd dif ferential pressure-actuated switches subject to excessive setpoint drift and requiring a high rate of surveillance testing. Currently some testirv) of the direct ac t ing instruments requires the plant to be placed in a half-scram condition when the instrument is out of service for calibration or testing. The installation of an ETS is cost-justified due to im'provements inplantavalkablityand the simplification of calibration procedures. The following are benafits achieved by the installation of an ATS:
o Reduce the time the reactor protection system must be in a half-scram condition to functionally test or calibrate a safety trip; -
- 4 73 Reduce the functional test f requency for Jhe
~
o primary sensor calibration from once perynih to once per operating cycle (at refueling)'for the
^
multi-channel variables;
~ ;.y

, o El'ininate the possibility of instrtImept valving errors; ,
o virtually eliminate instrument testing y,e, lated scrams; C o Reduce undetected primary sensor elesment drif t due to the utilization of a meter in each primary .
sensor signal loop; o Decrease the time required to functionally test or j calibrate the safety trip point from approximately one hour to a matter of seconds; ISSUED FOR l I

o Signif icantly reduce the number of Licensee Event Reports f iled with the NRC for setpoint drift; o Enable the trip units to be located in an area where the background radiation will remain at a low level for the life of the plant. This location will reduce the radiation exposure to the instrument technicians performing monthly calibrations required on some sensors.
