% CTION I INTRODUCTION AND DESCRIPTION 1.1 Int roduc tion This manual contains instructions covering General Electric flydraulic Control Units, Part Nos. 237E318G2 through GS. Each such unit functions within a hydraulic system to position one locking-piston control rad drive mechanism in a General Electric boiling water reactor. These instructions consist of descriptive and aperating information, replacement procedures, maintenance and trouble-analysis procedures, and a parts list. These instructions are identically applicable to llydraulic Control Units Part Nos. 237E918G2 through C5. The specific differences in these Groups (G) are noted in subsection I.~3, at 'tKiconclusion of this section.
This manual is prepared for use in conju.iction with the Control Rod Drive System Operating and Maintenance Manual for the particular nuclear power station for which hydraulic control units are provided. Consequently, this manual does not contain operation or maintenance instructions applicable to the overall control rod drive hydraulic system; these instructions are contained in the control rod drive system instruction manual referenced above.
- 1. 2 Description and Operating Principles The hydraulic cantrol unit combines all operating valves and components required for the normal or scram (rapid control rod insertion) positioning of a single control rod drive mechanism.
The unit functions on difiarential hydraulic pressures supplied by the control rod drive hydraulic system to insert or withdraw its associated drive mechanism, and to provide cooling water to the drive mechanism. The solenoid-operated valves which control normal directional movement of the drive mechanism respond to programmed signals from the reactor manual control system. The scram accumulator and scram valves are interconnected with the reactor protection system to func-tion as required to rapidly insert the assonated drive mechanism in the event of a scrara signal.
All hydraulic risers in the control un't are provided with manual shutoff valves which isolate individual components for servicing during reactor operation. External electrical connections from the reactor manual control sys:cm are routed through terminals in a single wiring trough assembly on the front of the unit to simplify trouble-analysis and repair.
Each major component in the hydraulic control unit has been assigned an Equipment Piece (EP) number. Figure 1-1 shews a piping and instrumentation diagram of the unit and includes these EP numbers. The number appearing in parentheses after the name of a component in the following text and in the subsequent sections of this manual is the EP numtm by which that component is identi-fled in Figure 1-1.
Figure 1-9, at the conclusion cf this section, shows an over-all view of the I fdraulic control unit and may be opened for simultaneous use with the discussions that follow. The EP numbers assigned to components shown on Figure 1-9 appear in the index to that figure, where they apply.
In addition to the illustrations provided in this section, the engineering drawings included in Section VI of this manual provide supplemental detail to the contents of this section and should be referred to as required. For an assembly drawing of the hydraulic control unit, see Draw-ing 237E918 in Section VI.

I GEI-92807 1.2.1 Piping Assembly The piping assembly (see Drawing 237E972 in Section VI) ts comprised of the seven hydraulic risers shown on Figure l-9, the manifold, and the inlet and outlet scram valves (126, 127).
Internal porting in the manifold (see Drawing 237E973 in Section VI) directs water between the seven risers and the valves installed on the hydraulle control unit. In addition, porting in the manifold contains the cooling check valve (138), the driving water check valve (137), and the three filter elements (134,135,136) which protect the directional control valves mounted on the mantfold as well as the drive mechanism from foreign matter in hydrtulic system water.
These components, and the four pressure test connections (P1 through P4), are accessible througn individual threaded plugs in the outside wall of the manifold.
Figure 1-2 shows a hydraulle circuit diagram of the interior of the manifold, together with the scram valves and hydraulic risers. The directional control valves sl.own in Figure 1-2 are mounted on the front surface of the manifold.
Table 1-1 lists the seven hydraulic risers and the water flowing through each to and from the mantfold during the various modes, or functions, of control rod drive cperation: inse rt,
withdraw, scram, and cooling when the drive is stationary at a latched position. Flow arraws on Figure 1-2 show the direction of water entering and leaving the manifold through the risers during the various modes of drive operation. The valve actions which result in these flows are described in the following subsections.
1.2.2 Cooline Section The cooling section of the hydraulic control enit consists of the cooling water riser and the cooling check valve (138). Cooling water is provided from the hydraulic system cooling water header to the cooling water riser to cool the control rod drive, and is admitted to the drive-insert riser at all times that the control rod drive is at a nationary position. Normal flow from the cooling water riser to the drive-insert riser thrr ugh check valve 138 is from 0.2 to 0.4 gpm at a pressure of appruximately 20 ;. il above reactor pressure. When a drive is in motion, pressure in the manifold to the drive-insert riser is higher than the cooling water i
pressure and valve 138 shifts to dose off the flow of cooling water.
r 1.2.3 Driving Section 1.2.3.1 Desc ription The four solencid-operated (50) directional control valves (120,121,122,123) shown in Figure 1-3 and on Drawing 112C2129 in Section VI, are mounted on a sub-p! ate installed on the piping assembly manifold. These valves are energized by the electrical relay action of the reactor manual control system to direct control pressurec through the hydraulic control unit to the under-and over-piston ports in the associated control rod drive as required for normal drive operation.

Manifold with Directional Contnl Valves f
By energizing and opening two of the four valves simultaneously, the hydraulic system drtve water header is connected through the manifold to either under or over the piston in the drive mechanism while the exhaust water header is simultaneously connected to the opposite side of the y
drive piston. In this manner driving pressure is supplied through the hydraulic cuatrol unit to d
insert or withdraw its associa6ed control rod. The two directional control valves (120,123)
I which include integral speed control elements are connected to the manifold so thu they always f l pass flow to or trom the drive-insert riser and the under-piston port in the control rod drive.
k s
I These speed control elements are manually adjustable so that control rod drive speed may be
'i f
regulated by increasing or decreasing the flow to or from the under-piston area. The flow through these valves 1.s approximately 4 gpm when the drive mechanism is being inserted at a normal speed b
1; of 3 inches per second, and approximately 3 gpm during drive mechanism withdrawal j3 f
Since common piping (see Figure 1-2 and Table 1-1) and porting in the manifold is used to and from the control rod drive for the purposes of cooling, driving, and scram, the directional
,)
control valves are periodically subjected to scram pressure. One of these valves (123) connected
,hl to the driving water riser can be opened by this higher pressure applied to its outlet po ts. The check valve (137) installed in the manifold porting to valve 123 prevents significant wati r loss to hj the drive water riser during scram. The cooling check valve (138), discussed in s.ab section 1.2.2, above, provides the identical fur.ction for the cooling water riser.

d i
The two scram pilot valves (117,118) are directly connected to the reactor protection system g
so that the inlet and outlet scram valves (126,127) open in response to scram signals. When open,
{
the inlet scram valve permits the scram accumulator to supply the initial hydraulic energy required i
to rapidly insert the associated control rod. The simultaneous opening of the outlet scram valve
!s permits water vented from the control rod drive to exhaust into the hydraulle system scram discharge f-header during a scram insertion. The accumulator monitoring instrumentation is interconnected y
with the reactor manual control system so that a remote alarm is provided in the event of gas or l
water leakage.
1.2.4.1 Scram Pilot Air Valves During normal power station operation, each of the two channels of the reactor protection system energizes one of the two 3-way solenoid-operated scram pilot air valves (117,118)
(See Drawing 885D661 in Section VI). When energized, these pilot valves supply instrument air f
to the diaphragm actustors of the inlet and outlet scram valves (126,127). Upon initiation of scram, both reactor protection system channels are de-energized and both pilot valves open, venting air l
precsure from the scram valves and permitting them to open. Figure 1-4 shot /s the energized and de-energized positions of the pilot valves.
To prevent spurious scrams, both pilo
- valves are interconnected so that both must be de-energized before control air -essure is vented from the inlet and outlet scram valves with the resulting rme.1 insertion s W rod irive associated with the hydraulic control unit.
De-energizing of ett'cr one or i
act valves will not result in scram since control air f
pressure will continue to be appliet.,o the iniet and outlet scram valves through the remaining I
energized pilot valve.
Control air pressure is supplied to the pilot valves through an isolation valve (116) from g
the hydraulic system scram v@p pilot air header. Valve 116 may be closed to isolate the pair f
of scram pilot air valves fer maintenance.

Both valves are basically similar, except that the inlet scrant valve (126) is a globe valve with an angular pattern while the outlet scram valve (127) is a straight-through globe pattern.
The internal spring prelead in the outlet scram valve is slightly greater than in the inlet scram

i 1.2.4.3 Scram Accumulator and Instrumentation E
The scram accumulator, consisting of the piston-type water accumulator (125) connected to the N cylinder (128), serves as an independent source of energy to initiate scram insertion of the 2
associated control rod drive. The accumulator and the instrumentation assembly occupy the lower section of the hydraulic control unit, as shown in Figure 1-6.
The piston in the water accumulator (125) serves as a barrier between the high-pressure nitrogen used as the scurce of stored energy and the water used to initiate control rod scram. The piston is sealed against leakage by two Tefion seals and a synthetic-rubber 0-ring installed la grooves alcund its outside wall.
The hydraulic system charging water header continuously pressurizes the water accumulator.
The ball-check valve (115) in the charging riser prevents backflow from the accumulator into the charging header, and ensures that the accumulator will retain its charge for a limited time in the i

of 1190 cubic inches, is initially precharged with gas from an external source through a connection (P6) in the instrumentation block to approximately 900 psig.
Initial charging of the accumulator with nitrogen is accomplished (when the reactor system i
is not pressurized) by closing the isolation valve (113) in the charging riser, then opening the wdle valve (107) in the accumulator drain line to discharge any water from the top of the cylinder.

Gas pressure is monitored by the pressure indicator (131) and a remote alarm of low gas pressure is provided by the low-pressure switch (130) on the rear of the block. The rupture disc assembly (132) installed in the gas porting in the block is rated at 2000 psi and provides over-pressure protection for the accumulator. The i
M shutoff valve (111), in addition to its function in chargini; the accumulator, permits the instruments to be isolated and serviced during power-station operation.

SECTION II DESCRIPTION AND OPERATING PRINCIPLES 2-1 INTRODUCTION 2-2 The description and operating principles ia this section are identically applicable to liCUs part Nos. 761F500G1 thru G9.
The common configuration of these units is illustrated in Figure 2-1 which calls out the nomenclature of significant compoacnts and pruvides lip numbers where applicable.
Drawing No. 730E145 in Section VII is a piping and instrumentation diagram of the HCU. Refer to drawing No. 761E500 in Section \\ II for an assembly drawing of the llCU.
2-3 Each IlCU functions within the control rod drive hydraulic system (CRDHS) to position one locking-piston CRD mechanism in the reactor. The HCU combines all operating valves and components required for normal (drive insert or drive withdraw) or scram (rapid control rod insertion) positioning of the associated CRD. The HCU directs differential hydraulic pressures supplied by the CRDHS to insert or withdraw the CRD and to provide cooling water to the CRD. The scienoid-operated valves that control normal directional movement of the CRD respond to timed signals from the rod drive control system (RDCS). The RDCS is an asynchronous multiplexing system which uses a transponder circuit board to decode terminal instructions and encode status data. The operating and maintenance instructions for the transponder circuit board are included in Section IV of this manual. The scram accumulator and scram valves are inter-connected with the reactor protection system (RPS) to function as required to rapidly insert the CRD in response to a reactor scram signal.
The state of readiness of the scram valves and accumulator is continuously monitored by instrumentation on the HCU and presented at the rod status display at the main control panel.
2-4 All hydraulic risers in the llCU are provided with manual shutoff valves which isolate individual components for servicing during reactor operation.
External cmnections for all electrical components in the HCU except the scram pilot valve solenoids are routed through terminals in a single wiring through assembly on the front of the HCU to simplify trouble analysis and re-pair. Connections to the scram pilot valve solenoids are routed thro gh the ciectrical junction box installed above the wiring trough.

GEK-394698 2-9 Scram Valve Bodies. Independent of their scram function, the valve bodies of the inlet and outlet scram valves also serve as junction points between the manifold and the risers. Water flows through internal porting in the valve bodies of the inlet and oulet scram valves as follows for normal CRD operation. A. At all times when the CRD is stationary, cooling water enters the inlet scram valve (126) body from the cooling water riser and flows into the insert riser to the CRD. B. During the drive-insert sequence, drive water flows through internal porting and associated components in the manifold to the inlet scram valve body, and then through the insert riser to the CRD. C. Water exhausted from below the CRD drive piston during the withdraw or settle sequence enters the inlet scram valve body from the insert riser, passes through the manifold and associated components and is discharged through the exhaust water header to the CRDHS. D. During the drive-withdraw sequence, drive water flows through internal porting and associated components in the manifold to the outlet scram valve (127) body and thence through the withdraw riser to the CRD. l.. Water exhausted from above the CRD drive piston during the insert se-quence enters the outlet scram valve body from the withdraw riser, ( passes through the manifold, and is discharged through the exhaust water riser to the CRDHS. 2-10 The scram valves are closed during normal reactor operation with the valve plugs isolating the valve body porting used in the functions described above from the scram porting. 2-11 Ball-check valves 114, 115, and 138 are installed in blocks in the scram discharge riser, charging water riser, and cooling water riser, respectively. Valve 114 prevents CRDHS scram discharge header backflow from entering the HCU through the out1>t scram valve during~and following reactor scram. Valve 115 prevents accumulator water from t ckflowing into the charging water riser. Valve 138 protects the cooling water riser from driving pressure or scram pres-sure backflow through the inlet scram valve. 2-12 Manifold. Internal porting in the manifold directs water between trm scram valve bodies, the directional control valves, the drive water risers and the exhaust water risers. These risers are directly connected to the mani-fold. In addi tion, porting in the manifold contains the drive water ball-check valve (137), which prevents backflow from the directional control valves into the drive water riser during a scram, and three filter elements (134, 135, 136), which protect the directional control valves and the CRD from particulate matter in CRDHS water, 2-7 hO ) S
GEK-39469B I 2-13 Test plugs P1 through P4 in the manifold provide connections for testing pressures as shown in Figure 2-2. Test plugs P3 and P4 are used primarily for measuring CRD under-piston (PU) and over-piston (PO) differential pres-sures (dP) to determine CRD operating capabilities. Test plug P5 is instal-led in the block of ball-check valve 114 in the scram discharge riser. 2-14 The test connections, filters, and drive water ball-check valve are ac-cessible through threaded plugs in the outside wall of the manifold. The threaded plugs of filter elements 134 and 135 serve as test plugs P1 and P3. 2-15 Cooling Water Riser. Cooling water is provided, from the CRDHS cooling water header through the cooling eater riser, to cool the CRD internal seals and bushings, and it is admitted through the inlet scram valve body to the in-sert riser et all times that the CRD is at a stationary position. Normal flow from the cooling water riser to the insert riser through ball-check valve 138 is from 0.22 to 0.34 gpm (0.83 to 1.29 t/ min) at a pressure of from 12 to 25 psi (0.84 to 1.76 Kg/cm ) above reactor pressure. When the CRD is in motion, 2 pressure in the inlet scram valve body is higher than the cooling water pres-sure, and check valve 138 shifts to close off the flow of cooling water. The check valve opens again to admit cooling water to tne insert riser when the CRD is stationary. 2-16 Directional Control Valves. The four directional control valves mounted on the manifold (see Figure 2-3) are energized by the rod drive control sys-tem (RDCS) to direct driving pressure and exhaust water through the HCU to and from the under-and over-piston ports in the associated CRD for normal control rod in and out positioning. By energizing and opening the directional con-trol valves in coordinated pairs, the drive water riser can be connected under or over the CRD piston while the exhaust water riser is connected to the op-posite side of the drive piston. 2-17 Two directional control valves (120, 123) include speed control elements and are connected to the manifold so that they always pass flow to or from the CRD under-piston port. This flow is approximately 3 gpm (11.4 t/ min) through valve 120 when the CRD is moving in the withdraw direction, and approxi-mately 4 gpm (15. 1 t/ min) through valve 123 when the CRD is moving in the in-sert direction at the normal speed of 3 in./sec (76 mm/sec). The balance of forces in the CRD is such that the pressure under the drive piston is approxi-mately PR+ 90 psi (6.33 Kg/cm ) whenever the CRD is either inserting or with-2 drawing. Proper speed for control rod insertion is obtained when the speed control element in valve 123 is set so that a flow of 4 gpm (15.1 t/ min) through the valve and piping to the CRD will produce a local pressure drop of approxi-2 2 mately 160 psi (11.25 Kg/cm ) (from PR+ 260 psi (PR+ 18.28 Kg/cm ] in the 2 CRDHS drive water header to PR+90 psi [PR+ 6.33 Kg/cm ] under the CRD drive piston). Similarly, for proper control rod withdrawal speed, the speed control 2-8 bE ,L a,a _' _ _. b-

GEK-39469B element in valve 120 should be set so that a flow of 3 gpm will produce a 2 local pressure drop of 95 psi (6.68 Kg/cm ) (from PR+ 110 psi [PR+ 7.73 2 2 Kg/cm ] under the CRD drive piston to PR+ 15 psi [PR+ 1.05 Kg/cm ] in the CRDHS exhaust water header). Once the speed control elements in directional control valves 120 and 123 are properly set, no further readjustment is re-quired except to compensate for changes in CRD internal piston seal leakage. 1.

GEK-39469B I 2-18 During scram, the directional control valves are subject to scram pres-sure through the porting in the manifold and scram valve bodies. The two directional control valves (122,123) connected to the drive water riser can be opened if subjected to this higher pressure at their outlet ports. The check valve (1s7) installed in the manifold prevents significant loss of water to the drive water riser during scram. The cooling check valve (138) performs the same function for the cooling water riser. 2-19 A timed device capable of phasing numerous voltages of specified duration upon command from the RDCS energizes the four directional control valves in pro-per sequence and duration for CRD movement. For single-step control rod inser-tion, valves 121 and 123 are energized for only the time (approximately 2 seconds) required to insert the caatrol rod drive slightly mora than one notch (approximately 6 inches [15.2 cm]) Valve 12~, opens the d ri ve wat er riser to the insert riser so that drivi,g pressure from the CRDHS is applied to the under-piston port of the CRD. Calve 121 opens the withdraw riser to the ex-haust water riser so that water venting from the CRD over-piston port is dis-charged to the CRDHS exhaust water header. 2-20 Following the deenergizing of valves 121 and 123, the settling circuitry of the control system automatically energizes and opens valve 120 for a period of several seconds. This opens the insert riser to the exhaust water riser so that the under-piston area of the CRD exhausts to the CRDHS, permitting the CRD piston and index tuFe to settle downward to the next latched position. ( 2-21 For control roc.ithdrawal, valves 121 and 123 are energized for approxi-mately one-half second as described abcvc in order to remcvc the load from the collet latch and cam it into the open position. Immediately followir.g this brief notch-in signal, valves 120 and 122 are automatically energized for CRD withdrawal. Valve 122 opens the drive water riser to the withdraw riser so that driving pressure is applied to the over-piston port of the CRD and to the annulus below the collet piston. Valve 120 opens the insert riser to the ex-haust water riser so that water venting from the under-piston port is discharged to the CRDHS exhaust water header. Following this, valve 122 closes to remove the force from the spring-loaded collet assembly and to reduce the rate of decent of the index tube. Valve 120 is maintained energized by the settling circuit, as described above. 2-22 Provisions in the RDCS permit the interruption of the preset time inter-vals for single-notch insertion or withdrawal sequencing of the directional control valves in order to extend their duration. In this event, valves 121 end 123 or valves 120 and 122 remain energized and open until deenergi:ed by the release of a manual switch on the operators benchboard. The settling cir-cuit, however, functions to energi:e and open valve 120 upon termination of any insert or withdraw signal, whether single-notch or continuous, due to the resumption and completion of the normal timing cycle. 2-10 F i~ j ) s0-
GEK-394698 2-23 SCRAM SECTION 2-24 The HCU components defined for the purpose of these instructions, as the scram section, consist of the following: ~ A. The inlet and outlet scram valves (126, 127) B. The scram pilot air valves (117, 118) or alternate scram pilot air valve (139) and the isolation shutoff valve (116) in the air line to these v.alves. C. The scram accumulator and associated valves and monitoring instrumen-tation. 2-25 The two scram pilot valves (EP 117, 118) or alternate scram pilot air valve (139) are energized through an electrical circuit which includes the functions of the electrical box (see Table 2-3). For a schematic of the electrical circuitry (EP 117, 118) refer to connection diagram 922D248 or for (EP 139) refer to 105D5634 in Section VII. The initial opening of the outlet scram valve connects the withdraw riser to the scram discharge riser se that water vented from above the CRD piston during the scram stroke is discharged into the CRDHS scram discharge header. A fraction of a second later, the inlet scram valve admits water from the scram accumulator and charging water header to the insert riser to supply the hydraulic energy to rapidly insert the associated CRD. The accumulator monitoring instrumentation provides an input to the RDCS so that a remote alarm is provided in the event of accumulator gas or water leakage at any time. 2-26 SCRAM PILOT VALVES. During normal reactor operation, each of the two logic channels (A and B) of the RPS energizes one of the two 3-way solenoid-operatec scram pilot valves (117, 118) or the dual solenoids on the 3-way re-dundant scram pilot valve (139). When energized, the pilot valve or valves supply control air pressure to the diaphragm actuators of the inlet and out-let scram valves, maintaining the scram valves closed. Upon initiation of scram, both RPS logic channels are deenergized thereby venting control pres-sure from the scram valve actuators and pcrmitting the stem and plug assemb-lies to withdraw from the valve bodies (to open). Figure 2-4 shows the ener-gized and deenergized positions of the pilot valves (117, 118 and 139). 2-27 To reduc e the probability of spurious scrams. the valve or valves are pneumatically configured so that both solenoids mrst be deenergized before con-trol pressure is vented from the inlet and outlet scram valve actuators, with the resulting CRD scram insertion. Deenergi:ing of either one of the valve solenoids will not result in a scram since control pressure will continue to be applied to the scram valve actuators. Failure of electrical power to both valve solenoids will preduce a scram of the CRD. 2-11 b

GEK-39469B ( 2-28 Control pressure is supplied to the pilot valves through isolation shut-off valve 116, which may be closed to isolate the scram pilot valves for main-tenance purposes. 2-29 INLET AND OUTLET SCRAM VALVES. The inlet and outlet scram valves (126, 127) are normally open valves held closed during normal reactor operation by control air pressure supplied to the tops of their diaphragm actuators b) the scram pilot valves (117, 118) or alternative scram pilot air valve (139). single air line from the scram pilot valve or valves suppl.ies control pressure to both scram valves. The scram valves open by internal spring pressure plus reactor water pressure and charging water pressure as a result of the removal of control air pressure. The internal spring preload in the outlet scram valve (127) is slightly greater than in the inlet scram valve (126). This permits the outlet scram valve to open before the inlet scram valve o ens in order to p prevent a backpressure buildup above the CRD drive piston upon application of scram pressure below the drive piston. 2-30 The outlet scram valve, when opened, connects the withdraw riser to the scram discharge riser, and water from above the CRD drive piston is discharged into the CRDHS scram discharge header as the result of reactor pressure act-ing through the ball-check valve located in the insert port of the CRD. In turn, the inlet scram valve opens the insert riser to the charging water header and the scram accuralator (refer to Figure 2-2) so that maximum pressure is applied to the CRC irive piston. Each of the scram valves is fitted with a stem-mounted positic n switch (see Figure 2-5). The position switch is actua-( ted when the valve plug has left the seat, and causes a SCRAM indicating light to energize on the associated rod status display in the control room to pro-vide a remote indication that the scram valves for the particular CRD have opened.

Both valves have soft seats to minimi:e seat leakage. 2-32 SCRAM ACCUMULATOR. The scram accumulator consists of the piston-type water accumulator (125) pressurized by a volume of nitrogen contained in the N2 cylinder (128). The accumulator and its instrumentation occupy the lower portion of the HCU as shown in Figure 2-1. The piston in the water accumu-lator forms a barrier between the high-pressure nitrogen used as the source of stored energy and the water used to initiate control rod scram. The piston is scaled against leakage past the barrier by 0-rings installed in grooves around its outside wall. The purpose of the accumulator assembly is to provide a local source of kenetic energy in the event that reactor pressure is low and/ or that the CRDHS fails or is depleted momentarily in a general scram. 2-14 l{ ll l 4
GEK-394698 ( 2-33 The CRDHS continuously pressurizes the water accumulator through the charging water riser at the HCU. Check valve 115 in the charging water riser retains the water in the accumulator for a limited time.in the event supply pressure fails and prevents backflow from the water accumulator into the charg-ing water riser. Upon initiation of scram, when the inlet and outlet scram valves (126, 127) open, the charging water pressure (approximately 1400 psi [98.43 Kg/cm ]) is admitted through the insert riser to the under-piston area 2 of the CRD. In the event charging water fails, there is adequate water capacity in the accumulator to complete the CRD scram stroke within the re-quired time provided that reactor pressure is normal. If the reactor pressure should exceed the accumulator or charging water pressure, the check valve in the insert port cf the CRD shifts, admitting reactor pressure to the under-piston area of the CRD Reactor pressure then furnishes the force required to complete the scram stroke. 2-34 Nhen the scram signal is manually cleared from the RPS logic circuitry the inlet and outlet scram valves again close, and the scram discharge volume is automatically drained. Full scram accumulator pressure is restored because the closed inlet scram valve blocks the charging water access to the CRD insert port. 2-35 Excessive loss of nitrogen will cause a decrease in nitrogen pressure which actuates the pressure switch (130) in the instrumentation block to pro-vide an alarm in the control room. 2-36 The water accumulator is also continuously monitored for water leakage across the piston. The level switch (129) actuates a control room alarm if water leaks past the accumulator piston and collects in the instramentation b'ock. The instrumente' ion block is installed below the accumulator in such a m:mner that it will rective all water leaking past the piston. 2-37 The at - mulator N2 cylinder is initially precharged with nitrogen from an external source through connection P6 in the instrumentation block. Once precharged, further charging is not required unless low nitrogen pressure is indicated hv the pressure indicator (131) on the instrumentation block. 2-38 ACCUMULATOR INSTRUMENTATION. The accumulator instrumentation is mounted on the instrumentation block below the scram accumulator as shown in Figures 2-6 and 2-7. The pressure switch (130) and liquid level switch (129)are in-terconnected with the RDCS to provide a control room alarm in the event of low gas pressure or water leakage at the scram accumulator. The contacts of the pressure switch open on decreasing pressure at 970 to 940 psig (68.19 to 66.08 Kg/cm g). The contacts of the float-type liquid level switch open when approxi-2 mately 60 cc of water exists in the instrumentation block. These instruments provide a local indication of the affected accumulator, in addition to the control room alarm of low pressure of ter Icakage. 1 2-15 kb O
