CEA 0FF-NORMAL OPERATION AND REALIGNMENT 2.0 REVIEW AND APPROVAL:
Reviewed by Facility Review Group March 10 1983 Approved by C. M. Wet,hy Plant Manager March 10 19E Revision 3 Reviewed by FRG d o e urf #7 19 lI Approved by M //)!f/2 M M _- Plant Itanager MN .2 5~-19 Q 3.0 PURPOSE AND DISCUSSION: 0
3.1 Purpose
This procedure provides instructions for operator action during abnormal operation and realignment of Control Element Assemblies (CEA) while in Modes 1 or 2. /R3
3.2 Discussion
- 1. The action statements applicable to a stuck or untrippable CEA, to two or more inoperable CEAs and to a large misalignment
(>15 inches) of two or more CEAs, require a prompt shutdown of tIIe reactor since either of these conditions may be indicative of a possible loss of mechanical functional capability of the CEAs and in the event of a stuck or untrippable CEA, the loss of Shutdown Margin.
- 2. For small misalignments (<15 inches) of the CEAs in a given group, there is 1) a small effect on the time d. pendent. long term power distributions relative to those used in generating LCOs and LSSS setpoints, 2) small effect on the available Shutdown Margin, and 3) a small af fact on the ejected CEA worth used in the safety analysis. Therefore, the action statement associated with small misalignments of CEAs permits a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> time interval during which attempts may be made to restore the CEA to within its alignment requirements. The one hour time limit is sufficient to (1) identify causes of a misaligned CEA, (2) take appropri' ate cdrective action to realign the CEAs and (3) minimize the effects of xenon redistribution.
FOR INFORMATION ONLY iliis document is not controlled. Before use, yerify inkmtion with a controlled document.

- 3. Overpower margin is provided to protect the core in the event of a large misalignment Q15 inches) of a CEA. However, this misalignment would cause distortion of the core power distribution. This distribution may, in turn, have a <
significant effect on 1) the available Shutdown Margin, 2) the time dependent long term power distributions relative to those >
used in generating LCOs and LSSS setpoints, and 3) the ejected l CEA worth used in the safoty analysis. Therefore, the action )
statement associated with the large misalignment of a CEA l requires a prompt realignuent of the misaligned CEA.
4 The action statements applicable to misaligned or inoperable CEAs include requirements to align the operable CEAs in a given group with the inoperable CEA. Conformance with these alignment requirements bring the core, within a short period of time, to a configuration consistent with that assumed in generating LCO and LSSS setpoints. However, extended operation with CEAs significantly inserted in the core may lead to perturbations in
- 1) local burnup, 2) peaking factors, and 3) available Shutdown Margin which are more adverse than the conditions assumed to exist in the safety analyses and LCO and LSSS setpoint determination. Therefore, time limits have been imposed on operation with inoperable CEAs to preclude such adverre conditions from developing.

B. Conduct a systematic check of the vent gas surge system by isolating components from the Nitrogen System and the vent gas surge header one at a time.
C. If nitrogen pressure is decreasing at an abnormal rate, readjust the nitrogen supply header pressure -
regulator to approximately 20 psig until the leak is located to prevent exhausting the nitrogen supply.
D. Check closed A0V-6300 (Reactor Drain Tank vent valve), A0V-6208 (Nitrogen stop to flash tank), and A0V-1400 (Quench Tank vent valve). If any of these valves are open, a continuous bleed of nitrogen from the Nitrogen System to the vent gas system will occur. /R1

3.1.1 This procedure provides instructions and guidance for restoration of power to the MA, MA-1, MB, MB-1, MC, MC-1, MD and MD-1 instrument biases on loss of normal inverter power. It also provides instructions for verifying or restoring power to PP-266 and PP-267 on loss of the
, 2A and 2B Inverters to the Oualified Safety Parameter Display System (QSPDS).
3.2 Discussion 3.2.1 Four pairs of redundant 1207 AC single" phase ungrounded
. instrument buses (2MA, 2MA':1', 2MB , 2MB-1,' 2MC, 2MC-1, . -
2MD, 2MD-1) provide uninterruptible power to the Reactor Protective System (RPS) and Engineered Safety Features Actuation System (ESFAS). Each bus is supplied separately.
, from an inverter connected to one of the two safety related 125V DC buses.'
To permit maintenance and backup power without disabling the instrument bus, maintenance transformers are provided for each inverter system. The system is arranged so that any single failure does not prevent the RPS and ESFAS from performing their safety functions.

3.2 (continued) i 3.2.2 In addition, two redundant 1207 AC single phase ungrounded buses (PP-266 and PP-267) provide uninterruptible power to
, the QSPDS and ESFAS instrumentation. Each Los is supplied
! separately from an invertar connected to one of the two
- safety related 125V DC buses.
To permit maintenance and backup power without disabling the
, QSPDS, each inverter has its own bypass systen, consisting of
! one power line conditioner (PIE).
i The inverters include an internal static switch which transfers the load to the bypass input line on detection of j ] internal faults. A manual "aske before break" bypass switch I is provided for each inverter to allow transfer from normal l d to bypass power supply during inverter outage without 1
interruption to the AC output.

3.1 This procedura provides instructions to be followed in the event of loss of Instrument Air.
3.2 If Instrument Air is lost completely, air-operated valves (such as CVCS Letdown Control Valves, etc.) will lose remote operating capability. Also, air-operated instrumentation will be lost. Under
, these conditions air-opere.ted valves must be operated on manual or backup syctems. /R1
4.0 SYMPTOMS
4.1 Any of the fallowing conditions are symptoms of decreased Instrument Air System reserve capacity:
- 1. Both Instrument Air Compressors running continuously.
- 2. Reduced Instrument Air pressure.
- 3. Instrument Air Low Pressure Alarm. '
/R1
- 4. Failure of normal or str.ndby Instrument Air Compressor to load e - ---
or start on signal.
i
- 5. Air supply line failure.
, 6. Unit I/II Instrument Air cross ties open.
- 7. Instrument Air Compressor Auto-Start Alarm.

5.0 INSTRUCTIONS
5.1 Immediate Automatic Actions:
5.1.1 Backup Instrument Air Compressor starts (85 peig decreasing).
5.1.2 Unit I/II Instrument Air cross ties open at decreasing pressure of 80 psig and close at either increasing pressure of 80 psig or continued pressure decrease to 70 psig. /R1 5.2 Immediate Operator Actions:
5.2.1 When Instrument Air pressere decreased below 85 psig., start the backup Instrument Air Compressor (if not already rimaning).
. 5.2.2 If Instrument Air pressure continues to decrease, line up the Service Air header to supply the Instrument Air supply headsr, and start the Service Air Compressor.
NOTE: Minimize the time that the Instrument and Service Air Systems are cross-connected.
5.3 Subsequent Actions 5.3.1 Check the pressure drop across the Bailey Filter.
5.3.2 If Instrument Air pressure can be stabilized:
- 1. Investigate the Instrument Air System for leaks, regulator or compressor failures, or malfunctions.
- 2. Verify that the dryers are properly aligned and the filters are correctly in service.
- 3. Correct any abnormal conditions.
5.3.3 If the decrease in Instrument Air pressure is caused by a loss of electrical power to an Instrument Air Compressor motor due to overload trip of the 480V MCC breaker 2-41331 or 2-42192: /R1
- 1. Determine that malfunction of the motor or breaker was not the reason for the trip. /R1
- 2. Rastore power at the appropriate MCC.
- 3. Start the Instrument Air Compressor.
