k:# 1. PURPOSE To provide procedures for operating the High Pressure Injection l q (HPI) System in each of the following modes:
NODE Section HPI Normal Lineup 4.0 High Pressure Injection Emergency Operation 5.0
,1
System Description
! The HPI System is designed to inject borated water into the Reactor
. Coolant System (RCS) to prevent the uncovering of the core in the case of a small reactor coolant piping leak (less than .5 ft2 break i ' size). Its automatic-initiation is from a containment pressure -
- exceeding 18.4 psia, or ( RCS' pressure of less than 1650 psig which initiates an SFAS incident level 2 signal to start the HPI pumps to open the HPI lines isolation valves, and to open the BWST outlet valves. _
. Upon receipt of the SFAS signal, the HPI pumps take suction from two separate supply-lines from the BWST (see Attachment 5). If the RCS pressure is dropping slowly, low HPI flow will occur since the
- ~HPI pumps are started at 1650 psig RCS pressure and a 500 GPM flow rate does NOT occur until approximately 1300 psig reacter coolant c;v pressure (see pump curve,. Attachments 3 and 4). To protect the 5
pump from overheating, a minimum flowpath is provided for each HPI
- pump to recirculate 35 GPM through restriction ~ orifices ROHP6A (HPI Pump 1-2) and ROHP6B (HPI Pump 1-1)-back to the BWST.
The four inch-discharge line from each HPI pump splits into two, 18 two and one half inch lines which connect to the resctor vessel cold leg inlets near the reactor coolant pump discharge. HPI Pump 1-1 discharges to the reactor coolant pumps 1-1-1 and 1-1-2 discharge piping and HPI pump 1-2 discharges to reactor coolant-pumps 1-2-1 and 1-2-2 discharge piping.
1 As RCS pressure drops, HPI flow will increase. If the flow increases to 475 GPM per line, the HPI high flow alarms will occur. .(See
- Attachment 6) (see ~ AP 3003.41-44.) The HPI pumps should not have i to be throttled unless a pipe break occurs or the HPI pumps are-
"piggybacked".
If the flow rate between the two HPI lines for a HPI pump becomes unbalanced due to abnormally high flow-in one line, the operator must throttle the HPI valve of the high flow line to split the flow between the injection. lines. Do NOT throttle the line with the high flow below the flow rate shown on Attachment 8. If makeup pumps are running, the indicated flow on the injection lines for HPI Pump'1-2
,- may be misleading.

- "}/
If the RCS pressure is too great to allow 1000 GPM flowrate per DH pump and the BWST level is low (less than 10 feet), the operator should decide if the motor operated crossover valves (DH63 and DH64) should be opened to allow for the low pressure injection (LPI) pumps 18 to provide the suction for the HPI System. This " Piggyback Operation" (see Attachment 5) must be done to provide the net positive suction head required for the HPI pumps and to provide a means for the LPI to operate when RCS pressure is greater than the 200 psig discharge of the LPI pumps.
When BWST level reaches 8 feet as monitored on LI 1525A, B, C, o.
D, or upon receipt of the annunciator alarm BWST LOLO VLV, XFER TO EMER SUMP at 8 feet in the BWST, the operator must close the BWST outlet valves (DH7A and DH7B) and open the containment vessel emergency sump outlet valves (DH9A and DH9B). When HPI pump suction is switched
'from the BWST to the outlet of the decay heat coolers, the operator must close the minimum recirculation valves, HP 31 and HP 32 to prevent contamination of the BWST and loss of water from the containmenc building.
The HPI " Piggyback" mode of operation must continue until the RCS ^
pressure drops to approximately 150 psig and the LPI pumps are supplying adequate flow, where the low pressure injection can be entirely transferred to direct injection-into the reactor by shutting off the HPI pumps. The HPI pumps do NOT have to be shut off as long 3 as they are throttled to less than 950 gpa flow. ,
.i.
If the break in the reactor coolant system is larger than 0.5 feet , 2 the RCS will depressurize to less than 200 psig before the BWST is depleted. Therefore, " Piggyback" operatics should NOT be necessary.
HPI pumps should only be secured after automatic actuation when the criteria of Section 2.7 are met. It should be noted that once the BWST is emptied to 8 feet, the pumps must be shut off or put into
" Piggyback" operation since there is no direct supply to the HPI pumps from the containment vessel emergency sump. - -
The HPI pumps can be used to supply makeup to the core flood tanks.
The flowrate from using one of the HPI pumps through restriction orifice R0 HP 7 is approximately 43 gpm. Only one of the HPI pumps should be used at a time to fill the Core Flood Tank. It should be c?ted, however, that the suction of the HPI pump is normally the BWST which will be approximately 2000 ppe boron concentration.
This will dilute the normal 3500 ppm boron concentration of the core flood tank. This mode of operation is detailed in Section 7 of SP 1104.01, " Core Flooding System Procedure".
Since the HPI pumps will normally be in emergency standby, if the isolation check valves leak, a computer alarm is supplied to detect this increase in the discharge pressure when the pump is off.

E _;.., Computer point P465 actuates Q479, the alarm "HP INJ VLV LEAKING TRBL/ NORM". The setpoint of the computer inputs PSH 2883A and PSH
. 2883B is 375 psig. , ,
For test purposes, a 250 spe recirculation line through R0 HP 1 is ,
provided. This line will be used from the Monthly Surveillance Test of the ECC System, ST 5051.01.
4 The HPI pumps flow test line valves HP 26 and HP 27 can be manually opened in the event of a,small break in the RCS. This could allow the flow from one HPI pump to enter all four injection lines. If one of the cold legs is the break area, the isolation valve in that line (HP 2A, HP 2B, HP 2C, or HP 2D) could be closed and the flow j . split into the remaining three injection lines. This is NOT a
- required safety action.
l
. The relaying for the HPI pump motors consists of four relays. The
- first of these relays is a long time relay with a setting of 105 amps primary current'(to the motor). This actuates the overload i indication in the control room only'and does NOT trip the pump.
^
- . The second relay is an instantaneous relay set at 210 amps that will' trip the motor if the long time relay is tripped and motor current is greater than 210 amps. This is the thermal overload.
The third relay is an instanteous relay set at 990 caps which requires
. - no other relay closure to trip. This is an overcurrent relay guarding
, h,s e against locked rotor current. The fourth relay is an instantaneous
~
ground fault relay set at 4.75 amps to protect the circuit against a gf
,c short to ground.
All trips will provide a white light at the control switch. It should be noted, however, that a white light-does not necessarily
, mean'the pump is tripped (see relay I description).

and b) Pressurizer level is being maintained.
CAUTION: Do not rely entirely on pressurizer level indication to determine the inventory of the.RCS. If the RCS temperature is not 50 degrees below the saturation temperature for the RCS pressure, a steam void may exist in the RCS.
If both of these conditions are satisfied, the HPI may be stopped by blocking and stopping the pumps, or throttled using HP2A, B, C, and D.
CAUTION: If 50*F subcooling cannot be maintained +
after stopping HPI, the HPI shall be started.
HPI may also be throttled during piggyback m operation to less than 950 spa per pump or as i required to balance flows. HPI flow may be ;f j
~"
stopped if both low pressure injection pumps are in operation with a flow of at least 1000 sps per pump, and the RCS conditions have been stable for 20 minutes.
- 2. If plant conditions are stable at normal operating or hot standby conditions after a transient with no evidence of a RCS leak, systems may be bypassed with the Shift Supervisor's permission. , , ,
- 3. If there are any questionable conditions or any sign of an RCS leak, no safety system should be bypassed without approval of Station Management (Station Superintendent or his designee).

- a. KP2A B F11 39 F 11C
- b. HP2B B Fil 41 F 11C
- c. HP2C B E11 03 E 11A
- d. HP2D B Ell 05 E 11A 4.2.4 Verify that the BWST contains at least 482,778 gallons of borated water. BWST level indicator LI 1525A, B, C, or T. should read greater than 37' 4".
4.2.5 Verify that no SFAS signals to the HPI system components have been bypassed.
NOTE: 1. Block the SFAS signal prior to reaching the HPI actuation point when the RCS is 18l being depressurized. Refer to " Station
i 9 SP 1104.07.17 p,
l Shutdown and Cooldown Procedure,"
b -+ PP 1102.10.
Blocking of SFAS components within this procedure is intended to prevent the failure or damage of the components.
The operator must note that changes in plant conditions may warrant placing the component back in an SFAS incident condition.
. 2. No SFAS actuation signals to the HPI system are to be bypassed above an RCS pressure of 1800 PSIG.
- 3. The HPI lines 2-2 and 1-1 have pressure indicators and computer alarms to indicate if the isolation valves are leaking. Use computer points P465 and Q479.
~
I 4.2.6 Notify the Shift Supervisor that the HPI system is in normal lineup.
- 5. HIGH PRESSURE INJECTION EMERGENCY OPERATION i No operator action is necessary to start the HPI system since it is
' automatically started from an SFAS incident level 2 signal (see Section 1). Abnormal flow conditions will be handled in the HPI line 1-1 (1-2, 2-1, 2-2) high flow alarm procedure AP 3003.41 (AP 3003.42, AP 3003.43, AP 3003.44) and Low Flow Alarm Procedures, AP 17 3003.51 (AP 3003.52, AP 3003.53, AP 3003.54). No operator sign off is required for Section 5.
5.1 Prerequisites 5.1.1 The HPI system is in normal lineup as per Section
~ ~
4 of this procedure.
I NOTE: The HPI system must be in normal lineup.
NOTE: Blocking of SFAS components within this L procedure is intended to prevent the failure or damage of the components. The operator must note that changes in plant conditions may warrant placing the component back in an -
SFAS incident condition. This is the responsibility of the operator performing the block.

'y ,
5.2.1 If a RCS break occurs and containment pressure increases to 18.4 PSIA or RCS pressure decreases to 1650 psig, i
an SFAS incident level 2 will be initiated.
5.2.2 The SFAS will:
- 1. Ensure the BWST outlet' valves DH7A and DH7B are open.
- 2. Open HPI isolation valves HP2A, HP2B, HP2C and HP2D.
- 3. Start the HPI pumps.
5.2.3 Verify that the SFAS has done what_is required in 2 Step 5.2.2.
NOTE: Any failure of equipment should cause an annunciator and/or computer alarm. .
If the flow rate between the two EPI lines for a HPI pump becomes unbalanced due to abnormally high flow in one line, the operator must throttle the HPI valve of .] ,
the high flow line to split the flow between - -
the injection lines. . U.32 Do NOT throttle the line with the high flow below the flowrate shown on Attachment
- 8. If a makeup pump is running, the indicated flow in the injection lines for HPI Pump 1-2 may be misleading.
5.2.4 Monitor BWST level and RCS pressure using the computer
~ '
' ~
! and/or control room instrumentation in order to be prepared for " piggyback" operation. See Step 5.2.7.
