j 2202-1.3 Revision 8 9;

d 05/12/78 APR 2 3 1979 2.1.1 MU-V17 will open to compensate for reduced pressurizer level.

2.1.2 Additional pressurizer heaters will come on in response to reduced reactor coolant pressure.

2.2 Manual Action 2.2.1 Verify MU-V17 open and pressurizer heaters on.

2.2.2 "CLOSE" MU-V376 letdown isolation valve, & " START" the backup MU pump, if required.

2.2.3 Reduce load at 10% minute & proceed with normal shutdown.

2.2.4 "LINE-UP" waste transfer pump from a R.C. Bleed Holdup Tank &

pump to the makeup tank to maintain required level.

2.2.5 If for any reason the operator cannot maintain Make-uo Tank and Pressurizer levels above their respective low level alarm setooints, " TRIP" the reactor, " INITIATE" Safety Injection manually (push buttons on canel 3), & then "Close" MU-V12.

3.0 FOLLOW UP ACTION 3.1 Safety Injection Not Initiated.

3.1.1 Initiate uait shutdown & coolcuan per 2102-3.1 and 2102-3.2 respectively.

3.2 Safety Infection Manually Initiated (HPI and LPI).

3.2.1 Verify that the Makeup Pumps & Decay Heat Removal Pumps start satisfactorily.

3.2.1.1 Close MU-V12 and MU-V18.

3.2.2 Sypass the SAFETY INJECTION by DEPRESSING the Group Reset Pushbuttons & " THROTTLE" MU-Vl6A/B/C/D as necessary to maintain

_t 220" pressurizer level and not exceed 250 GPM/HPI flow leg.

3.2.3 If MU pump flow drops below 95 GPM, trip excess MU pumps.

  • NOTE:

HPI String A flow is the sum of MU 23 FEl&2.

HPI String B flow is the sum of MU23 FE 3&4.

3.2.4 Verify that Safety Injection equipment is in its ESF position as shown in Table A-1.

3.2.5

_ CAUTION:

Continued operation depends upon the capability to maintain pressurizer level and RCS pressure above the 1640 PSIG Safety Injection Actuation setpoint.

l 1.

If pressurizer level can be maintained above the low level alarm point and the RCS pressure above the Safety Injection Actuation point, then proceed to step 3.2.6.

2.

If pressurizer level cannot be maintained above the low level ala.m point and the RCS pressure above the Safety Injection Actuation point, then the plant has suffered a major rupture and operation should continue according to Part B - Leak or Rupture of Significant Size Such that Engineered Safety Features Systems are Automatically Initiated.

3.2.6 With the pressurizer level and RCS pressure being maintained within allowable limits, initiate plant shutdown and cooldown per 2102-3.1 and 2102-3.2, respectively.

NOTE:

The HPI System is being used for makeup control and valves MU-V16A/B/C/D will have to be throttled to maintain pressurizer level.

As RCS pressure decreases, it may be possible to return to the normal makeup flowpath and secure HPI.

If MU pump

~

flow drops below 95 GPM as a result of throttling, "Open" MU-V36 & 37 to provide MU pump recirculation path to MU Tank.

Monitor MU Tank level and open MU-V12 as required.

cooling only one DH string should ce used for decay heat removal (i.e. - recirculation from the RC System).

The other DH string should be mai>teined on standby for use in recirculating water from the RB sump to the RC system.

NOTE:

The ECCS B(A) string is new in " piggy-Back" operation providing makeup to the RCS from the RB sump as required.

3.2.9 After R.C.S. pressure decreases to = 200 psig, throttle HPI discharge flow by throttling MU-V16A/B/C/D. Observe that LPI pumps now deliver water to RCS via DH-VaA/B.

3.2.10 When MU-V16A/B/C/D (HPI flow '[alves) are closed, stop the Hi pressure injection pumps & close CH-V7A & 7B from the LPI pump discharge. Injection flow path is now as follows:

Spill coolant to RB sump, RB sump to LPI pumps, LPI pumps to RCS via UH-V4A/B.

3.2.11 Throttle DH-V128A & B as required to maintain 220" pressurizer level and max. LPI pump ficw of 3C00-33C0 gpm.

NOTE:

CAUTION:

The actions to be taken for switching suction from the BWST to the R.B. sump depend upon the number of operating ECCS injection strings and the delivered flowrates in these injection strings. Based upon the existing situation, in the ECCS, proceed as outlined below to perform switch over of suction to the RB sump:

Situation G,o to Step 1.

Both LPI strings are operating and 3.6 indicated flow in each is above 750 gpm.

2.

Both LPI strings are operating 3.7 but indicated flow in each is below 750 gpm.

?.

One _?I string is inoperative.

3.8

.;37E:

The main objective when switching suction from the BWST to the RB sump is to maintain ECCS flow through two flow paths.

3.6.2.1 If not already done, THROTTLE BS pump's flows back to 1600 gpm per pump.

This must 'm done prior to taking suction from the RB sump.

3.6.3

" SHUT OFF" HPI pumps (pump control in control room).

3.6.4 Verify the ECCS suction valves CH-V6A & B from RB sump automatically open at BWST level of 7'.

3.6.5 When suction valves from RB sump are full open, "CLOSE the ECCS suction valves (DH-V5A & B) from the BWST.

3.6.6

" REPOSITION" LPI flow control valves (DH-V128 ASB) to obtain 3000 GPM each string if necessary.

(Flow rate could change due to change in suction sources).

3.6.7 Proceed to step 3.9.

3.7 Both LPI Strings Are Operating But Indicated Flow In Each Is Below 750 GPM.

3.7.1 When the BWST level reaches approximately 12', initiate the following steps.

3.7.2 If not already done, " THROTTLE" HPI strings' flow rates back to 500 GPM per pump each using control v lves MU-V16A, B, C, and D (flow rate indication and valve control in control room).

3.7.5

'Enen suction valves from RB sump are fully open, "Close" the ECCS suction valves (OH-VSA & B) frem the BWST. The ECCS is now in " piggy-back" operation.

3.7.6 Proceed to step 3.9.

3.8 One LPI String is Inoperative 3.8.1 The BWST 7' automatic transfer to the RB sump is reached in approximately 55-80 minutes frca initiation of ECCS injection, depending upon reason for string failure (j.e. - local LPI failure or diesel failurel. Prior to actuation of the lo-lo level alarm, initiate the folicwing steps.

3.8.2 Using the controls in the control room, attempt to " START UP" the non-operating LPI 5tring.

If successful, proceed to step 3.6.

If not successful, proceed to step 3.8.3 below.

3.8.6 If not already done, THROTTLE BS pump's flows back to 1600 GPM per pump.

This must be done prior to taking suction from the RB sump.

3.8.6.1 When the BWST level decreases to 7' 'sERIFY the ECCS suction valves (DH-V6A & B) frcm RB sump automatically open.

3.8.7 When suction valves from RB sumo are full open (position indic: cion in control room), "CLOSE" the ECCS suction valves (DH-V5A & B) from the BWST.

3.8.8

" REPOSITION" LPI flow control valve (s) (DH-V128A and/or B) as required to obtain proper string flowrates.

(Flow rates could change due to change in suction sources).
