Salem 2 Page 5 of 40 Rev. 39 3.0 PRECAUTIONS AND LIMITATIONS
___ 3.1 The SM, CRS, NCO, Containment Coordinator, and personnel involved in the RCS draining evolutions should review:
S2.OP-AB.RHR-0001(Q), Loss of RHR.
S2.OP-AB.CONT-0001(Q), Containment Closure.
___ 3.2 Sight Glass Level Indicator should be periodically monitored during draining activities IAW Attachment 1. Level in the Sight Glass should be cross-checked against other level indications at least once every 15 minutes, during draining, when level is #109 ft. elevation (Refer to Attachment 1, Section 2.0 when an erroneous level reading is suspected).
___ 3.3 The Mid-Loop Wide Range indicator 2LI18070 OR RVLIS is required to be operational when Pressurizer Cold Calibration level goes off scale. Performance of Step 5.1.2 may be impacted by the crud burst. Consider Radiation levels prior to performing Step 5.1.2 following an RCS crud burst.
___ 3.4 MAINTAIN RHR flow IAW with the following guidelines:
[C0102]
Operation of RHR Pumps at lower flow rates greatly reduces the possibility of air ingestion (vortexing) in the RHR Pump suction.
MAINTAIN continuous RHR flow between 1800 and 3000 GPM to ensure adequate pump casing cooling. RHR Pump operation at <1800 GPM should not exceed 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> in any 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period. Time <1800 GPM should be maintained IAW S2.OP-DL.ZZ-0001(Q), Control Room Logs.
Technical Specification minimum allowable RHR flow is 1000 GPM in Mode 6. Operation at <1500 GPM flow rate should be minimized to limit RHR System vibration.
___ 3.5 Chemistry Department should monitor CVCS Holdup Tank Oxygen concentration during RCS drain down until Oxygen concentration stabilizes below 1%.
___ 3.6 Reduced RCS Inventory Log is required to be maintained IAW SH.OP-DL.ZZ-0027(Q),
Temporary Reading Log & Log Supplement, whenever RCS level is below Pressurizer level indication.
___ 3.7 Any time level is below the PZR cold calibration indication, at least two independent level indications should be available. One of the indications should be the Sight Glass when level #109 ft.
___ 3.8 In order to prevent an uncontrolled RCS level change, the SJ54 valve associated with any accumulator that is not COMPLETELY DEPRESSURIZED should remain closed.
S2.OP-SO.RC-0005(Q)
Salem 2 Page 6 of 40 Rev. 39
___ 3.9 IF draining Steam Generators using nitrogen, THEN:
3.9.1 Carts may be connected to all four loops simultaneously.
3.9.2 No more than three pressurized N2 bottles are to be attached to any cart.
3.9.3 Stop draining Steam Generators if the Nitrogen Skid relief valve opens.
___ 3.10 A maximum of one Safety Injection Pump OR one Centrifugal Charging Pump shall be OPERABLE IAW Technical Specification 3.5.3 as verified by 4.5.3.2.a or 4.5.3.2.b while in Mode 5 or 6 with the head on the Reactor Vessel.
___ 3.11 23 Charging Pump flow path shall be aligned to Unit 1 OR the pump shall be C/T
[C0565]
when 21 or 22 Safety Injection Pump is capable of injection into the core with the RCS temperature #312°F with the Reactor Vessel Head installed.
___ 3.12 RCS operation at reduced inventory without RVLIS removes the ability to monitor for voiding in the reactor head due to gas coming out of solution from the RCS. A Head Vent Path must be established AND maintained at reduced inventory.
(80061345)
___ 3.13 Power supplies for RCS level Instrumentation are identified in Exhibit 3. These power supplies must be available for Instrumentation to be functional and may be used to assist in troubleshooting loss of indication.
S2.OP-SO.RC-0005(Q)
Salem 2 Page 7 of 40 Rev. 39
___ 3.14 When the RCS is vented to Containment with either the Containment Equipment Hatch or Personnel Air Lock open, Salems interpretation of NUMARC 91-06 requires that when a loss of RHR occurs either 1) the RCS is made INTACT (Note 1) prior to the time to Core Boiling, or 2) Containment Closure is established prior to the time Core Boiling.
For the purpose of establishing Containment Closure prior to the time to Core Boiling, the applicable penetrations are the Equipment Hatch, the Personnel Air Locks, and 2VC1, 2VC4, 2VC5 & 2VC6; Containment Closure of all the other penetrations is required prior to Core Uncovery and is established IAW S2.OP-AB.CONT-0001(Q).
NOTE 1 -
INTACT is defined as all RCS penetrations between the Core and Containment Atmosphere are isolated, and a minimum of two (2) RCS Loops with U-tubes not drained and their associated Steam Generators are Available as Heat Sinks (Note 2) for natural circulation.
NOTE 2 -
Available as Heat Sinks indicates each associated Steam Generator has a feed makeup source available, secondary water level is above the U-tubes, and a Steam Generator vent path exists.
___ 3.15 Any cooldown or heatup of the Steam Generators when the Steam Generator
[70038182]
U-tubes are filled with nitrogen will affect the RCS level due to the expansion or contraction of the nitrogen. Charging and letdown will have to be adjusted to maintain desired level.
___ 3.16 The following information is based on previous performance of this procedure:
The total capacity of the Steam Generators (primary side) is.29,000 gallons.
(Reference DCP 80083522)
Refueling Outage 1R19 -.17,000 gallons drained from the Steam Generators as a result of Draining The Steam Generators Using Nitrogen.
(Reference SAP Order 70090695).
Refueling Outage 2R17, Draining The Steam Generators Using Nitrogen was completed on previous shift. RCS volume drained to this point is unknown.
.5,000 gallons was drained when PZR level was lowered from.24% to.9% and
.10,890 gallons was drained when level was lowered from 9% to 103Nelevation.
This includes water from the Pressurizer and Steam Generator U-Tubes.
(Reference SAP Order 70104604).

S2.OP-SO.RC-0005(Q)
Salem 2 Page 20 of 40 Rev. 39 5.2.22 MONITOR the following indications while draining the RCS:
Available channels of instrumentation (Pressurizer Cold Calibrated level, Sight Glass level, RCS Mid-Loop Wide Range level) or RVLIS levels, ensuring levels trend together until Pressurizer Cold Calibrated level channel goes off-scale, and RW ST OR CVCS Holdup Tank Level, as applicable, to ensure expected level response.
5.2.23 When the required RCS level is obtained, ADJUST Letdown and Charging to maintain stable RCS level.
NOTE While stabilizing levels, the following instrumentation, if available, should be used to verify accuracy of instrumentation and completion of venting prior to isolating the Reactor Head Vent System:
Midloop Wide Range compared to Sight Glass is +/- 0.5 ft.
RVLIS Refueling/Reduced Inventory Level compared to Sight Glass is +0.17 to -0.33 ft.
(RVLIS indication is within +0.17 to -0.33 ft of Sight Glass level) (1)
RVLIS Channel A compared to Channel B is +/- 0.25 ft. (1)
(1)
When RVLIS is used in place of the Midloop Wide Range CAUTION Reactor Vessel Head Vent System should remain in service for a period of time to ensure Reactor Head is completely drained and vented. This will ensure level is stable before isolating.
[CR990409071]
5.2.24 IF Reactor Vessel Head is in place, AND RCS or Refueling Cavity fill will be initiated, THEN SECURE the Reactor Vessel Head Vent System as follows:
A.
ENSURE venting is completed as indicated by no air being drawn in through the 2RC39 vent path.
B.
CLOSE AND LOCK 2RC38, HEAD VENT LINE VENT VALVE.
C.
CLOSE AND LOCK 2RC39, HEAD VENT LINE VENT VALVE.
D.
REMOVE hose and poly bottle from 2RC39, if not already removed.
