PACIFIC GAS AND ELECTRIC COMPANY NUMBER STP R-10C NUCLEAR POWER GENERATION REVISION 25 DIABLO CANYON POWER PLANT PAGE 1 OF 18 SURVEILLANCE TEST PROCEDURE UNITS TITLE: Reactor Coolant System Water Inventory Balance 1 2 AND 05/20/04 EFFECTIVE DATE PROCEDURE CLASSIFICATION: QUALITY RELATED
- 1. SCOPE 1.1 Determine the gross leak rate or IDENTIFIED and UNIDENTIFIED LEAKAGE from the reactor coolant system (RCS) by taking the difference in RCS and "chemical and volume control system" (CVCS) inventory change over a reasonable period of time without inventory makeup.
- 2. DISCUSSION 2.1 Tracking the RCS inventory in a consistent manner provides an effective means of quantifying overall system leakages. Non-RCS sources of water added to the RCDT and PRT are eliminated or quantified when utilizing Table 4 to determine IDENTIFIED LEAKAGE.
2.2 If the gross RCS leak rate measured in STP R-10C exceeds 1 gpm (or 0.965 gpm if zinc injection is in service), this procedure will consider the following leakage parameters to allow the SFM to classify the leakage:
2.2.1 PRT Level 2.2.2 RCDT Level 2.2.3 RCDT Flow Totalizer 2.2.4 Accumulator Leakage to the RCDT 2.2.5 RCS Leakage to Secondary (Stm. Gen.)
2.2.6 RCS Leakage to CCW 2.2.7 Other IDENTIFIED LEAKAGE, which may be tracked as necessary with Volume 9 2.2.8 Initiate an Action Request (AR) to document actions taken. Create a PIMS evaluation screen (EVAL) to be routed to the maintenance rule program (PTMR).

These leaks are evaluated by other means. Examples are as follows:
2.3.1 RCS to steam generators - determine from activity analysis of secondary coolant.
2.3.2 RCS to CCW - determine from CCW activity analysis and increasing level in surge tank.
2.3.3 Letdown/Charging - determine from increasing auxiliary building area radiation monitors and airborne activity.
2.3.4 RCS to accumulators are not identified in this procedure.
- 3. RESPONSIBILITIES 3.1 Shift foreman (SFM), for operation of the equipment as required, for obtaining test data, for data reduction as required by this procedure and for evaluation of reactor coolant system leakage.
3.2 Chemistry engineer, for determining primary system leakage to the secondary system and the component cooling water system.
- 4. FREQUENCY 4.1 This test shall be performed when required by STP I-1B or as directed by the shift foreman.
4.2 RCS water inventory balance whether performed in STP I-1B or STP R-10C shall be current when operating in MODES 1 through 4 and may be performed in MODES 1 through 5.

- 7. VITAL 4KV SWITCHGEAR - GUIDANCE FOR EVALUATING OPERABILITY APPENDIX When applying the guidance for evaluating vital 4kV switchgear operability, the objective is to ensure vital components are operable based on the bus remaining structurally and electrically operable. The following guidance can be used to navigate through the various sections of this appendix.
To maintain the See the following for requirements Section 7.1 Component or cubicle operable.
Table 1 Section 7.2.1 Bus structurally operable.
Table 2 Section 7.2.2 Bus electrically operable.
Table 3 7.1 CUBICLE OPERABILITY 7.1.1 Open Doors to Support Maintenance NOTE 1: The term "cubicle door" or "cubicle doors" does not include panels.
NOTE 2: The term "cubicle" includes the breaker, the component fed by that breaker, and the components installed in the cubicle.
- 1) Opening 4kV cubicles doors and maintaining the cubicle operable can be risk significant and should be assessed for risk by maintenance and operations per MA1.DC11 and/or AD7.DC6, as applicable. Troubleshooting should be assessed per MA1.DC10.
- 2) Provided the conditions of paragraphs 5) and 6) below are met, 4kV bus cubicles may remain OPERABLE when cubicle doors are open to support maintenance.
- 3) If the conditions of paragraphs 5) and 6) below are not met when cubicle doors are open, the cubicle is INOPERABLE.
- 4) The following table specifies cubicle configurations and bus combinations allowed when cubicles are operable with open doors.
Table 1: Operable Cubicles with Open Doors Allowed cubicle Allowed cubicles Allowed number Mode configurations per bus of busses 1-4 See Table 2 2 1 5, 6, and See Table 2 2 3 Defueled
- UNCONTROLLED PROCEDURE - DO NOT USE TO PERFORM WORK orISSUE FOR USE ***
Identification and Resolution of AD4.ID8 R9 Loose, Missing, or Damaged Fasteners Page 7 of 10
- 5) In modes 1 - 4, to maintain cubicle operability, the following conditions shall be met:
a) The shift foreman shall grant permission, per OP1.DC18, to open cubicle doors. If the cubicle doors will be open more than one shift, shift foreman permission shall be obtained at the beginning of each shift the cubicle doors are open.
b) The open cubicle shall be attended at all times by a person who is familiar with the maintenance. Anytime the cubicle is unattended, the cubicle doors shall be shut and properly bolted.
c) Cubicle doors should not be open longer than 24 continuous hours.
NOTE: The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period is a nominal period rather than a to-the-minute period.
This guideline is intended to control the duration doors on operable cubicles are open. The expectation is that reasonable efforts will be made to ensure cubicle doors are not open longer than the guideline.
- 6) In modes 5, 6, and defueled, to maintain cubicle operability, the following conditions shall be met:T36309 a) The shift foreman shall grant permission, per OP1.DC18, to open cubicle doors. If the cubicle doors will be open more that one shift, shift foreman permission shall be obtained at the beginning of each shift the cubicle doors are open.
b) The open cubicle shall be attended at all times by a person who is familiar with the maintenance. Anytime the cubicle is unattended, the cubicle doors shall be shut and properly bolted.
NOTE: The risk assessment for operable cubicles with open doors in modes 5,6, and defueled determined that there is an insignificant increase in risk. Therefore, there is no time limit for having operable cubicle doors open.
7.1.2 Loose or Missing Bolting
- 1) If a cubicle door or panel is not fully bolted, the cubicle may be INOPERABLE.
- 2) The criteria for determining operability of an individual cubicle are:
a) Upper front door bolting -- If two or more bolts are missing or not properly installed, the cubicle is INOPERABLE.
b) Lower front door bolting -- If two or more bolts are missing or not properly installed, the cubicle is INOPERABLE.
c) Back door bolting -- If three or more bolts are missing or not properly installed, the cubicle is INOPERABLE.
NOTE 1: For the purposes of determining operability, the vertical panel located just above the back door is be part of the back door.
NOTE 2: The loose or missing bolt criteria stated in a, b, & c above is stand alone and cannot be combined with each other. That is, multiple bolt problems, other than as stated, can make the cubicle inoperable and requires evaluation.

Identification and Resolution of AD4.ID8 R9 Loose, Missing, or Damaged Fasteners Page 8 of 10 7.2 BUS OPERABILITY NOTE: Bus maintenance that makes bus G inoperable does not make breaker 52-HG-15, startup power, or cross-tie capability inoperable. (See AR A0477404) 7.2.1 Structural Integrity
- 1) Cubicles a) Two cubicles in any bus can have open doors, open panels, or missing or improperly installed bolts without affecting operability of the entire bus. Refer to paragraph 5) below for allowable configurations.
b) If three or more cubicles have open doors, open panels, or missing or improperly installed bolts, the entire bus is INOPERABLE.
- 2) Top Horizontal Panel Bolts a) Up to four bolts can be missing or improperly installed on one or two cubicles in a bus without affecting bus operability.
b) If bolts are missing or improperly installed on three or more cubicles, the entire bus is INOPERABLE.
Example:
- Three bolts missing or improperly installed on one cubicle and one bolt missing or improperly installed on another cubicle is acceptable.
- One missing or improperly installed bolt on each of three cubicles in a bus makes the bus INOPERABLE.
- 3) Side (End) Panel Bolts a) If two or more bolts are missing or improperly installed on the side (end) panel of a bus, the bus is INOPERABLE.
b) Two bolts, one side (end) panel bolt and one top panel bolt, can be missing or improperly installed without affecting bus operability.
- 4) PT Drawers a) The auxiliary feeder PT drawers and startup feeder PT drawers are structurally independent from the 4kV bus; therefore, these PT drawers may be opened without affecting bus operability.
b) One PT drawer on a bus may be opened at any time without affecting bus operability.
c) If more than one PT drawer is opened on a bus, the bus is INOPERABLE.

- 5) Breaker/Ground Buggy Positions a) The door/panel configurations in the following table relate the text of paragraphs 1) through 3) above to breaker/ground buggy positions that have been seismically analyzed to maintain bus structural integrity, thus bus operability.
(1) Maintaining an acceptable breaker/ground buggy position is required for both operable and inoperable cubicles.
(2) Two cubicles per bus can have doors or panels in the indicated configuration.
These door/panel configurations are stand alone and cannot be combined with each other.
(3) Unless otherwise indicated, the breaker/ground buggy positions are analyzed for modes 1 - 6 and defueled.
(4) Having a cubicle with the front and rear door open and the breaker racked in(up) is not analyzed. This configuration makes the bus INOPERABLE.
b) Other configurations may be acceptable, contact engineering for evaluation.

- 1. SCOPE 1.1 This procedure implements the Safety Function Determination Program (SFDP) as required by TS 5.5.15.
- 2. DISCUSSION 2.1 The purpose of the SFDP is to ensure that the proper actions are taken upon failure to meet one or more TS LCOs. It is also the goal of this program to ensure that the allowed out of service time of supported systems is not inappropriately extended as a result of multiple, overlapping support system inoperabilities.
2.2 TS LCO 3.0.2 establishes that upon discovery of a failure to meet an LCO, the associated ACTIONS shall be met. TS LCO 3.0.6 specifies that when a supported system LCO is not met solely due to a support system LCO not being met, the Conditions and Required Actions associated with this supported system are not required to be entered. Only the support system LCO ACTIONS are required to be entered. This is an exception to LCO 3.0.2 for the supported system. If this option is exercised, a safety function determination evaluation shall be made in accordance with TS 5.5.15.
2.3 When a support systems Required Actions directs a supported system to be declared inoperable or directs entry into Conditions and Required Actions for a supported system, LCO 3.0.2 shall be followed.
- 3. DEFINITIONS 3.1 Support System A support system is a structure, system, or component (SSC) required by Technical Specifications, which provides support for supported system(s) in order for the supported system(s) to perform its safety function. An example of a support system required by Technical Specifications would be Component Cooling Water (CCW). CCW supports the Residual Heat Removal (RHR) system by providing cooling to the pumps and heat exchangers.
An SSC that monitors or maintains a process parameter or operating limit is not a support system for the purpose of implementing TS LCO 3.0.6. For example, if the rod position deviation monitor is inoperable, this does not automatically mean that the control rods are no longer within their required alignment. A process parameter or an operating limit is not a support system. For example, exceeding control rod insertion limits does not automatically mean that hot channel factors are out of limits.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 2 OF 10 TITLE: Safety Function Determination Program 3.2 Supported System A supported system is a structure, system, or component (SSC) required by Technical Specifications, which requires a support system to ensure its safety function can be performed. Process parameters and operating limits are not supported systems for the purpose of implementing TS LCO 3.0.6.
A support system can also be a supported system. For example, the CCW system supports RHR system operation. As such the CCW system is a support system.
However, the Auxiliary Saltwater System (ASW) supports operation of the CCW system to remove heat. In this case the CCW system is a supported system.
3.3 Safety Function In the SFDP, safety function refers to intended function of the component or system to provide mitigation for those accidents previously analyzed and licensed for DCPP. The safety function for a component or system covered by an TS LCO can be obtained from the applicable TS Bases or in the FSAR. A single component or system may be covered by more than one TS LCO and have more than one safety function.
3.4 Loss of Safety Function 3.4.1 A loss of safety function exists when, assuming no concurrent single failure, and assuming no concurrent loss of offsite power or loss of onsite diesel generators, a safety function assumed in the accident analysis cannot be performed for the mode of applicability. If a loss of safety function is determined to exist by this program, the appropriate Conditions and Required Actions of the LCO in which the loss of safety function exists are required to be entered.
3.4.2 For the purpose of this program, a loss of safety function may exist when a support system is inoperable and:
- a. a required system redundant to the system(s) supported by the inoperable support system is also inoperable.
- b. a required system redundant to the system(s) in turn supported by the inoperable supported system is also inoperable.
- c. a required system redundant to the support system(s) for the supported systems (a) and (b) above is also inoperable.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 3 OF 10 TITLE: Safety Function Determination Program Generic Diagrammatic Example:
Train A Train B System 1 System 1 Case b System 2 System 2 Case a System 3 (Support System Inoperable) System 3 System 4 System 4 Case c 3.4.3 Due to the 3 vital bus and the cross connected design of the CCW/ASW system, DCPP does not neatly fit into the generic example above. The purpose of the program is to ensure that sufficient cross train checks are performed to ensure that inoperabilities of redundant components (functions) in both trains do not go undetected.
3.5 Safety Function Determination Program This is a program required by TS 5.5.15 to detect a loss of safety function and ensure that appropriate TS actions are implemented.
3.6 Cascading Technical Specifications When a support system is inoperable such that it results in a supported system inoperability the option always exists to enter the Conditions and Required Actions of the LCO for both systems. This is referred to as cascading technical specification Conditions and Required Actions. However, LCO 3.0.6 provides the option to only enter the support system LCO Conditions and Required Actions provided a loss of safety function has not occurred.
- 4. RESPONSIBILITIES 4.1 The SFM is responsible for:
4.1.1 Determination if implementation of TS LCO 3.0.6 is appropriate for the existing plant conditions and if allowed by the particular support system that is inoperable. Some technical specifications provide actions on declaring supported systems inoperable upon discovery of support system inoperability.
4.1.2 Performing a loss of safety function determination required by TS Administrative Controls 5.5.15, if appropriate.
4.1.3 Ensuring that no inappropriate completion time extensions exist due to multiple support system inoperabilities.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 4 OF 10 TITLE: Safety Function Determination Program INSTRUCTIONS 5.1 The Safety Function Determination Program (SFDP) as implemented by this procedure does not change the way in which operability of technical specification equipment is determined. The shift foreman (SFM) shall continue to use the guidance provided in OP1.DC17, "Control of Equipment Required by the Plant Technical Specifications," to evaluate individual equipment operability.
5.2 Entry into TS LCO 3.0.6 can be considered whenever the SFM declares a support TS support structure, system, or components (SSC) inoperable. This in no way precludes the shift manager (SM) or SFM from implementing TS LCO 3.0.2 and tracking the Conditions and Required Actions for all supported equipment affected by the support system inoperability. This is referred to as "cascading" technical specifications and is allowed by TS. Review the following criteria prior to implementing TS LCO 3.0.6.
5.2.1 The unit is in Modes 1 - 4. DCPP will only enter TS LCO 3.0.6 in Modes 1- 4.
It has been determined that use of TS LCO 3.0.6 is not advantageous in Modes 5 and 6. See Step 5.4 for more explanation.
5.2.2 Determine if the support systems LCO requires direct entry into the supported systems TS LCO. If so, enter all applicable Required Actions of the support and supported systems TS LCOs. TS LCO 3.0.6 cannot be invoked for that supported system TS LCO.
5.2.3 If the failure of an TS required support system results in the inoperability of an TS supported system, then LCO 3.0.6 may be applied.
5.2.4 If the failure of an TS required support system results in the inoperability of a system outside of TS, and that system is subsequently relied upon by an TS supported system to remain OPERABLE, then LCO 3.0.6 may be applied.
5.2.5 TS LCO 3.0.6 cannot be applied when solely a non TS support item makes an TS LCO item inoperable. There are no Required Actions of the support item to provide the level of protection required for application of TS LCO 3.0.6.
5.2.6 If the failure of an ECG required support system results in the inoperability of an TS supported system, then the ECG and TS LCO Required Actions are required to be entered. TS LCO 3.0.6 cannot be applied.
5.2.7 If there are other support systems which are contributing to the supported systems inoperability, then TS LCO 3.0.6 may NOT be applied without first considering each of the other support systems separately to ensure no loss of safety functions exists.
5.2.8 If the inoperable SSC is not directly addressed by an TS LCO and does not impact the operability of an TS LCO, then no further action with regard to a LOSF evaluation is required and this procedure may be exited.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 5 OF 10 TITLE: Safety Function Determination Program 5.3 Inoperability of a support system does not necessarily render a supported system inoperable. For example:
5.3.1 Declaring CCW Pump 2 inoperable does not render either RHR pump 1 or 2 inoperable due to the cross connected design of the CCW system.
5.3.2 Supported systems are not declared inoperable when an instrumentation support system TS LCO is not met, unless the failure results in a loss of actuation capability or the support system's Required Action directs the supported system to be declared inoperable.
5.3.3 Supported systems are not declared inoperable solely as a result of inoperability of the normal or emergency electrical power source. The Required Actions for inoperable electrical power sources provide the necessary restrictions.
5.4 TS LCO 3.0.6 does not limit the modes of applicability for implementation of SFDP to only Modes 1-4. However, for simplicity DCPP will not use SFDP in Modes 5 and 6.
This will require the SFM and SM to consider the effect on supported systems when a support system is inoperable and cascade technical specifications as appropriate. It is assumed that implementation of SFDP in Modes 5 and 6 is not advantageous since most systems only require a single train for the safety function to be met. In those cases where 2 trains are required (e.g., RHR when loops are not filled in Mode 5), the SFM needs to address multiple system inoperability and take the TS Required Actions for all support and supported systems.
5.5 An LOSF evaluation is required if TS LCO 3.0.6 is invoked after considering the criteria of Step 5.2. The LOSF evaluation must be performed as soon as practical for each inoperable TS support or TS supported system.
5.6 Documentation of the LOSF evaluation shall be in the PIMS TS tracking module of the inoperable support equipment evaluated.
5.7 If an LOSF is determined to exist, the appropriate Conditions and Required Actions of the LCO in which the LOSF exists shall be entered. If no Condition within the LCO addresses the LOSF, then TS LCO 3.0.3 shall be entered.
5.8 A considerable amount of judgment may be required to perform an LOSF evaluation.
Attachment 8.2, "SFDP Worksheet," is optional for determining if an LOSF evaluation is required. The attachment poses questions to guide the SFM/SM in determining if a more detailed analysis of a loss of safety function is required.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 6 OF 10 TITLE: Safety Function Determination Program Attachment 8.1, Support System - Supported System Matrix," provides a cross reference of identified support system LCO to supported system LCO relationships. This list is for reference and may be overly conservative depending on the exact cause for declaring the support system inoperable. However, the control room staff can use this list to quickly determine the potential for an LOSF. When a support system TS LCO is not met, Attachment 8.1 can be used to check if any of the listed supported system's TS LCOs are not met. If any supported system Conditions and Required Actions are currently in effect then a more detailed analysis for an LOSF must be performed. This analysis will consist of checking that the supported TS safety function is identified (check TS Bases) and still available assuming no concurrent single failure or loss of offsite power.
5.8.1 Examples
- a. Unit 1 is in Mode 1 and the SFM has declared RHR Pp 1-1 inoperable due to a clearance for maintenance. RHR Pp 1-1 is an SSPS Train B actuated component.
The asset team has scheduled reactor trip breaker testing for SSPS Train B during the same shift that the RHR pump is cleared. The SFM reviews Attachment 8.1 and determines that TS LCO 3.3.2 is a support system for TS LCO 3.5.2. Closer inspection reveals that the same train is affected and there is no loss of safety function. This evaluation is documented in the PIMS TS tracking module.
- b. Unit 2 is in Mode 1 and the SFM has declared the spray additive tank inoperable. The SFM reviews Attachment 8.1 and determines that TS LCO 3.6.7 is not listed as a support system for any other TS LCO.
Since the spray additive system is NOT a support system for the containment spray system and there are no other TS LCO Conditions in effect, no LOSF exists. This evaluation is documented in the PIMS TS tracking module.
- c. Unit 1 is in Mode 1 and the SFM has authorized SSPS Train A testing that makes that train inoperable. A nuclear operator doing rounds in the turbine building discovers a problem with SIP 1-2 4kV breaker cubicle rendering SIP 1-2 inoperable. TS LCO 3.3.2 is listed as support system for TS LCO 3.5.2. In this condition automatic initiation of SIP 1-1 is prevented due to SSPS testing and SIP 1-2 will not start due to a breaker problem. In this case the LOSF evaluation would show a loss of safety function due to both SIPs inoperable and TS LCO 3.0.3 would be entered.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 7 OF 10 TITLE: Safety Function Determination Program 5.9 Some TS LCOs have Conditions and Required Actions that require technical specification cascading. When a support system's Required Action directs a supported system to be declared inoperable or directs entry into Conditions and Required Actions for a supported system, the applicable conditions and Required Actions are entered in accordance with TS LCO 3.0.2. It should be noted that an LOSF evaluation is still required for the remaining inoperable supported system TS LCOs (Modes 1-4). The directed technical specification cascading may not cover all affected safety functions.
5.10 Common Support Systems 5.10.1 RWST
- a. It is recognized that if the RWST is inoperable due to insufficient inventory or inadequate chemical concentration, the acceptance criteria for certain design basis accidents may not be met. Neither the ECCS nor containment spray system can meet their design function with the RWST outside the required TS LCO limits. Since this is clearly stated in the TS Bases for the RWST, the appropriate action is to follow the TS Required Actions for an inoperable RWST and not to enter TS LCO 3.0.3 for the ECCS. The LOSF evaluation will conclude that although there is a degradation in the ECCS, there is not a loss of safety function as long as useable inventory is present. The RWST Required Actions are bounding for this case.
5.10.2 CST/FWST
- a. The AFW system will not be able to perform its design function without a supply of water for RCS decay heat removal via the SGs. The Required Actions for inoperability of the CST or FWST is more restrictive than for the case if all three AFW trains are inoperable. The appropriate action is to follow the TS Required Actions for an inoperable CST/FWST and not to enter the Required Actions for an inoperable AFW system. The LOSF evaluation will conclude that although there is a degradation for maintaining an AFW heat sink there is not a loss of safety function as long as there is useable inventory. The CST/FWST Required Actions are bounding for this case.
5.10.3 ULTIMATE HEAT SINK (UHS)
- a. The ultimate heat sink provides a heat sink for transferring heat from safety related components during a transient or accident, as well as safety related and nonsafety related heat loads during normal operation. The ASW system is a supported system of the UHS. If the UHS is inoperable the capability to remove heat by the ASW system is impacted. ASW system performance will be degraded with an inoperable UHS but this alone does not make the AWS system inoperable as long as the UHS does not exceed 70degreesF. The appropriate TS Required Actions to ensure the plant is maintained in a safe condition are the Required Actions of TS 3.7.9. Entry into TS 3.7.8 and TS LCO 3.0.3 are not required.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 8 OF 10 TITLE: Safety Function Determination Program 5.10.4 Diesel Fuel Oil, Starting and Turbo Air
- a. The DFO storage volume is based on 7 days of minimum ESF loads during a loss off offsite power. In the event insufficient DFO volume is available the Required Action is to restore inventory within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
The diesel generators are supported systems. Although the diesel generators would not be able to support minimum ESF loads for 7 days, they are still meeting their safety function as long as they are running.
The LOSF evaluation for this case concludes that the system is degraded but the safety function of the DGs are met as long as there is useable volume in either DFO storage tank.
- b. The TS minimum requirements for DG starting air and turbo air ensure that there is sufficient air capacity for 3 successive DG start attempts. If air pressure is less than 180 psig but greater than 150 psig, there is adequate capacity for one start attempt and the DG can be considered operable until the Completion Time for the Condition expires. The TS LCO Conditions and Required Actions direct declaring any DGs inoperable should they not have at least 150 psig in one starting air receiver or the turbo air receiver. An LOSF evaluation is not required since the TS LCO 3.8.3 Required Actions does not consider the associated DG inoperable within the Completion Time. After expiration of the Completion Time, a directed entry to declare the DG inoperable is required. In this case, entry into TS LCO 3.0.6 is not allowed.
5.11 Cross Connected Systems Since CCW and ASW are cross connected cooling systems, pumps and heat exchangers do not have strict train relationship with respect to cooling ECCS equipment. It should be noted that there is no analysis for one CCW pump during design basis accidents. If one CCW pump is out of service and the DG associated with an operable CCW pump becomes inoperable, TS 3.8.1 Condition B, Required Action B.2 requires declaring that CCW pump inoperable within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. With no vital CCW loop available the SFM will direct entry in TS LCO 3.0.3. Application of TS LCO 3.0.6 is inappropriate in this case.
5.12 If an inoperable support SSC is covered by an ECG and this SSC makes an TS supported system inoperable, it is not allowed to invoke TS LCO 3.0.6. The supported system Conditions and Required Actions must be followed if the supported system is inoperable due to the ECG support system inoperability. TS LCO 3.0.6 is dependent on support system Conditions and Required Actions providing the appropriate level of safety and compensatory actions for supported system inoperability. The ECGs have not been reviewed to provide this level of safety.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP1.DC38 DIABLO CANYON POWER PLANT REVISION 1 PAGE 9 OF 10 TITLE: Safety Function Determination Program 5.13 Supported System Maximum Completion Time NOTE: A supported system Completion Time may only be extended when there is no Loss of Safety Function.
5.13.1 A supported system made inoperable by support system inoperabilities may only remain inoperable for a limited period of time without entering the supported system's Conditions and Required Actions. This time limit is defined as the Maximum Completion Time. The Maximum Completion Time for restoring the supported system to operable status is the Completion Time specified for restoration of the first inoperable support system plus the Completion Time specified for the inoperable supported system.
- a. If the supported system is not restored to operable status by restoring the support system(s) to operable status within the Maximum Completion Time, enter the Condition and Required Actions for the inoperable supported system's Completion Time not met.
5.13.2 Example of Completion Time Extension
- a. The unit is in Mode 1 when 480 V bus H becomes deenergized due to a feeder breaker problem. TS LCO 3.8.9 specifies that this bus must be restored to operable status in 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or a shutdown to Mode 3 is required in the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. 480 V bus H (TS LCO 3.8.9) is a support system for containment isolation valves (TS LCO 3.6.3). The seal return penetration has CVCS-8112 (bus H) inside containment and CVCS-8100 (bus G) outside containment. TS LCO 3.6.3 Required Actions gives the operator 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to complete action to restore or isolate the penetration before a shutdown is required. An LOSF evaluation would conclude that there is no loss of safety function since CVCS-8100 is still powered and able to function on a phase A isolation signal assuming no concurrent single failure or loss of offsite power. The Conditions and Required Actions of TS LCO 3.6.3 are not required to be performed for 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> since its support system Required Actions are in effect. After 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, then the Required Actions of TS LCO 3.6.3 are applied. Isolation of the seal return penetration, assuming power is not restored to CVCS-8112, must be completed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
5.13.3 Documentation and Tracking of Maximum Completion Time
- a. Initiate a PIMS TS Tracking Sheet listing the supported system Maximum Completion Time for the following instances:
- 1. The support system restoration Completion Time has expired, or
- 2. Multiple support system inoperabilities have occurred affecting the same supported system.

- 1. Loss of Safety Function (LOSF) Evaluation
- a. Has the Unit entered the Required Actions of more than one TS LCO?1
- If No, then no LOSF exists. No further evaluation and action is required.
- If Yes, Continue with next Step 1.b.
- b. Has the Unit entered the Required Actions of other TS LCOs for redundant train equipment?
- If No, then no LOSF exists. No further evaluation required.
- If Yes, Continue with next Step 1.c.
- c. Has the Unit entered the Required Actions of other TS LCOs for redundant train support or supported equipment applicable to this LCO (consult Attachment 8.1)?
- If No, then no LOSF exists. No further evaluation required.
- If Yes, a LOSF may exist. Perform a LOSF evaluation to ensure that redundant safety equipment is not affected by the support system inoperability.
SUPPORTED SYSTEM REQUIRED ACTION ENTRY TABLE SUPPORT INOPERABLE AFFECTED MAXIMUM INOPERABLE SYSTEM TS LCO TIME/DATE SUPPORTED COMPLETION TIME TIME/DATE OF SYSTEM TS LCO ALLOWED= THE AFFECTED SUPPORTED SUPPORT SYSTEM SYSTEM AOT + SUPPORTED SYSTEM AOT 1
This question provides simplistic screening criteria for an LOSF evaluation. In general, if this is the only TS LCO Condition the unit has entered, then all safety functions should be preserved. Always consider and evaluate common support systems, (i.e., RWST, CST/FWST - See Step 5.11) and single power supply supported systems such as DRPI. The supported system TS LCO list should always be consulted when entering an TS LCO condition to ensure that redundant equipment is available.

- 1. SCOPE 1.1 This procedure describes the proper posting requirements utilized at DCPP for the purpose of radiological control.
- 2. DISCUSSION 2.1 Routine and special radiological surveys are performed to maintain a knowledge of the radiological conditions of plant areas. Areas with radiological conditions in excess of specified limits are posted to identify the conditions within. Components within these posted areas may require additional markings to identify specific radiological conditions (e.g., contamination under insulation, sample sinks, etc). Consistent and correct radiological posting is essential to maintain compliance with Federal regulations and to inform personnel of the radiological hazards associated with particular areas.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER RCP D-240 DIABLO CANYON POWER PLANT REVISION 16 PAGE 2 OF 15 TITLE: Radiological Posting UNITS 1 AND 2 2.2 A standard radiation posting sign is used at DCPP. The sign consists of three sections:
a heading, a symbol, and inserts.
2.2.1 The heading contains the words: "CAUTION," "DANGER," or "GRAVE DANGER."
2.2.2 The conventional three bladed radiation symbol is located near the heading.
Normally the bladed area is magenta. It may also be black or purple. The background is yellow.
2.2.3 The CAR system of posting radiological areas requires that each sign has an insert for C-contamination, A-airborne, and R-radiation and that they be in the following order under the three bladed symbol:
- a. Contamination
- b. Airborne
- c. Radiation 2.2.4 Each insert is color coded
- a. Green: No radiological concern exists.
- b. Yellow: Low to moderate radiological concern exists.
- c. Red: A high level of radiological concern exists.
2.3 Additional informational signs, placards, labels or tape may be used in conjunction with the CAR posting to provide more specific detail about the radiological condition.
2.4 Components that require additional radiological information may be identified by barrier tape and/or informational labels instead of the CAR posting.
- 3. DEFINITIONS 3.1 Accessible - means an area that can be occupied by a major portion of an individual's whole body.
3.2 Accessible Overhead Area - An area greater than eight feet is accessible if a platform or ladder is configured such that the area becomes accessible to an individual. All other overhead areas are inaccessible.
3.3 Airborne Radioactivity Area - is (per 10 CFR 20.1003) a room, enclosure or area in which airborne radioactive materials, composed wholly or partly of licensed material, exist in concentrations:
3.3.1 Exceeding 100% of the derived air concentrations (DAC) specified in Appendix B of 10 CFR 20.1001 - 20.2402.
OR 3.3.2 To such a degree that an individual present in the area without respiratory protective equipment could exceed, during the hours an individual is present in a week, an intake of 0.6 percent of the annual limit on intake (ALI), or 12 DAC-hours.
3.4 Barricade - a door, gate, chain, rope or any such item that obstructs passage.
3.5 Component - equipment, piping, valves and other parts within an area.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER RCP D-240 DIABLO CANYON POWER PLANT REVISION 16 PAGE 3 OF 15 TITLE: Radiological Posting UNITS 1 AND 2 3.6 Controlled Area - is (per 10 CFR 20.1003) an area, outside of a restricted area but inside the site boundary, access to which can be limited by the licensee for any reason.
3.7 High Radiation Area (HRA) - is ( per 10 CFR 20.1601) an area accessible to personnel with radiation levels that could result in an individual receiving a deep dose equivalent (DDE) of greater than 100 mrem in one hour measured at 30 cm from the radiation source or from any surface that the radiation penetrates.
3.8 Locked High Radiation Area (LHRA) - is an area accessible to personnel with radiation levels that could result in an individual receiving a DDE of greater than 1000 mrem PER HOUR measured at 30 cm from the radiation source or from any surface that the radiation penetrates.
3.9 In One Hour - means a cumulative dose averaged over a period of one hour, as opposed to a constant dose rate measured "per hour."
3.10 Radiation Area - is (per 10 CFR 20.1003) an area accessible to personnel with radiation levels that could result in an individual receiving a DDE of greater than 5 mrem in one hour measured at 30 cm from the radiation source or from any surface that the radiation penetrates.
3.11 Radioactive Material Area - is (per 10 CFR 20.1902) a room or area accessible to personnel in which radioactive material is used or stored that exceeds ten times the amounts specified in Appendix C of 10 CFR 20.
3.12 Radiological Controls Area (RCA) - is ( per DCPP administrative control) an area in which access is controlled for the purpose of radiation protection, in part, through the use of a Radiation Work Permit. The permanent RCA includes the Containment Buildings, the Fuel Handling Buildings, most of the Auxiliary Building, the Radwaste and Laundry Buildings, the area between the Auxiliary Building and the Radwaste Buildings, and the Calibration Facilities located in the Turbine and Buttress Buildings.
3.13 Restricted Area - is (per 10 CFR 20.1003) an area, access to which is limited for the purpose of protecting individuals against undue risks from exposure to radiation and radioactive materials. Normally a restricted area boundary is the same as either the permanent or temporary RCA boundary with which it is associated. Restricted areas not associated with an RCA may be setup with the approval of the RPM or designee provided they are documented in an AR within two working days. The AR should contain the rationale for the setup and steps taken to insure compliance with regulatory and procedural requirements.
3.14 Surface Contamination Area (SCA) - is (per DCPP administrative control) an area accessible to personnel in which smear surveys indicate removable contamination equal to or greater than 20 DPM/100 cm2 alpha.
OR Surface Contamination Area (SCA) - is (per DCPP administrative control) an area accessible to personnel in which smear surveys indicate removable contamination equal to or greater than 1000 DPM/100 cm2 beta-gamma.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER RCP D-240 DIABLO CANYON POWER PLANT REVISION 16 PAGE 4 OF 15 TITLE: Radiological Posting UNITS 1 AND 2 3.15 Very High Radiation Area (VHRA) - is an area (per 10 CFR 20.1602) accessible to personnel with radiation levels that could result in an individual receiving an absorbed dose of greater than 500 rads in one hour measured at one meter from the radiation source or from any surface that the radiation penetrates.
- 4. RESPONSIBILITIES 4.1 Radiation protection is responsible for maintaining the radiological postings in all plant areas in accordance with this procedure.
- 5. PREREQUISITES None
- 6. PRECAUTIONS 6.1 Posting Placement 6.1.1 Where practical, placement of posting materials should avoid attachment to plant piping or components.
- a. Posting and barricade material should be attached using metal hasps and an approved adhesive (stock code 73-0664 or 72-6333 or an approved equal). Temporary adhesive attachment anchors, i.e., wall stickies, should not be used. Wire-ties are not temporary adhesive attachments and are acceptable anchor points.
- b. The requirements of CF4.ID8, "Temporary Attachments," shall be followed where attachment to piping or components cannot be reasonably avoided.
- c. The requirements of CF5.ID12, "Consumable Material Control," shall be followed where contact with affected corrosion resistant alloys cannot reasonably be avoided.
- 7. INSTRUCTIONS 7.1 General 7.1.1 Signs and postings that meet the wording requirements of sections 7.2 through 7.9 of this procedure, and the requirement for the magenta radiation symbol on a yellow background, are in compliance with the regulations and as such are considered acceptable.
- a. The CAR posting should use a standard 3-pocket sign. Barrier rope should be used to identify the area boundaries.
- b. Typically such signs and postings are located in infrequently accessed areas and are "holdovers" from the time period before the CAR system was introduced at this plant. Such signs and postings should be brought up to the CAR standards in a timely manner.
7.1.2 When used as required, a "CAUTION," "DANGER," or "GRAVE DANGER" sign shall be visible from each accessible point of entry into the posted area.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER RCP D-240 DIABLO CANYON POWER PLANT REVISION 16 PAGE 5 OF 15 TITLE: Radiological Posting UNITS 1 AND 2 7.1.3 When practicable, discrete areas meeting the Radiation Area, High Radiation Area or Locked High Radiation Area criteria should be individually posted.
Posting of a very large area or building is generally inappropriate if most of the area does not meet the applicable criteria.
If most of the area within a building or on a floor meets the Radiation Area or High Radiation Area criteria, all entrances to the area may be posted in lieu of posting each discrete area within.
If rooms or areas have components, equipment, or work evolutions which cause variable dose rates, a larger boundary may be established with the postings based on the higher of the expected conditions.
- a. Examples of appropriate use of these larger boundaries include:
- 1. Posting of the area on 140' elevation between Unit 1 and Unit 2 Containment Buildings or large portions of the 115' elevation backyard area during periods of bulk movement of radioactive material, such as during outages.
- 2. Posting of large portions of the 55' elevation Auxiliary Building due to the automatic discharge function of the Reactor Coolant Drain Tank.
7.1.4 If rooms or areas have work evolutions which cause short term airborne radioactivity, a larger boundary may be established with the postings based on the higher of the expected conditions.
- a. The postings within the larger boundary do not require updating.
- b. The posting at the larger boundary contains additional information which describes the reason for the short term posting.
7.1.5 Additional informational signs, placards, labels or tape may be used in conjunction with the CAR posting to provide more specific detail about the radiological condition. See Appendix 9.4 for descriptions of the more commonly used informational signs.
7.1.6 Where uses of the color magenta is specified for purposes of posting, the following substitutions may be made:
- a. Purple or red may be used for the radiation symbol or radiological barricade rope/tape. Black may also be used for the radiation symbol.
7.1.7 General Posting Exceptions
- a. Overhead areas that are inaccessible do not require posting and/or barricading. It is considered a prudent action to place a posting if the area is considered easy to post.
- b. Except for a VHRA, the need for any other required posting may be deleted for periods of less than eight hours IF personnel responsible for positive control over access to the affected area are in attendance sufficient to either prevent access, or to control access in accordance with an applicable Radiation Work Permit.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP RB-2 DIABLO CANYON POWER PLANT REVISION 5 PAGE 2 OF 6 TITLE: EMERGENCY EXPOSURE GUIDES UNITS 1 AND 2
- 2. DISCUSSION 2.1 Authorization of emergency exposure is an extraordinary measure, but justifiable under four sets of circumstances.
When the intended action requiring a potential overexposure to an emergency worker, is expected to result in;
- Saving or preserving the quality of a human life that would otherwise be lost.
- Significant projected dose saving to others.
- Protection of valuable property.
- Sampling results required to redefine or adjust existing Protective Actions for the public or site personnel.
All of the above situations require that no reasonable method is immediately available (or readily apparent) to avoid exceeding the established annual limits and that every effort will be made to keep the emergency exposure ALARA.
2.2 The emergency exposure guidelines implemented at DCPP are consistent with the Environmental Protection Agency (EPA) guidance for controlling doses to workers under emergency conditions. (Reference 10.3) 2.3 Authorized dose limits for workers during emergencies are based on avoiding acute health effects and limiting the risk of delayed health effects.
2.4 Emergency worker exposures are not controlled by Planned Special Exposures.
NOTE: Planned Special Exposures may be implemented during non-emergency situations including Recovery Operations. Refer to RP1.ID8, "Planned Special Exposures."
2.5 An emergency exposure should be authorized only once in an individual's lifetime and is in addition to any prior occupational exposure from normal or planned special exposures.
2.6 The emergency exposure limits specified in this procedure are applicable to both in-plant team response activities and off-site field monitoring by the company's ERO personnel.
2.7 Emergency exposure above 25 rem TEDE shall require the voluntary consent of the authorized individual.

3.3 Committed Dose Equivalent (CDE) The dose to the organs or tissues that would be received from an intake of radioactive material by an individual during the 50 years following the intake.
3.4 Committed Effective Dose Equivalent (CEDE) The sum of the products of the weighting factors applicable to each of the body organs or tissues that are irradiated and the CDE to these organs or tissues.
3.5 Corrective Actions Those emergency measures taken to mitigate or terminate an emergency situation at or near the source of the problem in order to prevent an uncontrolled release of radioactive material or reduce the magnitude of a release.
3.6 Declared Pregnant Woman (DPW) A woman who has voluntarily informed her supervision, in writing, of her pregnancy and the estimated date of conception.
3.7 Deep Dose Equivalent (DDE) Dose associated with external exposure of the whole body at a depth of 1 cm.
3.8 Lens Dose Equivalent (LDE) External exposure to the lens of the eye at a depth 0.3 cm.
3.9 Lifesaving Action Any of several activities that are necessary to save human life including search and rescue, first aid, transport and emergency medical care.
3.10 Occupational Dose Dose received by an individual in the course of employment in which the individual's assigned duties involve exposure to radiation and to radioactive material.
3.11 Planned Special Exposure Dose received in addition to and accounted for separately from the doses received under the limits of 10 CFR 20.1201 as a planned and specially authorized exposure in accordance with 10 CFR 20.1206.
3.12 Shallow Dose Equivalent (SDE) External exposure of the skin or any extremity (depth 0.007 cm).

EP RB-2 ATTACHMENT 9.6 DCPP Emergency Exposure Guidelines 1 2 AND The following table contains guidelines for use in authorizing emergency exposures when lower doses are not practicable:
RADIOLOGICAL PROPERTY DOSE SAVING LIFESAVING ASSESSMENT SAVING TO TO SAMPLING POPULATION* INDIVIDUAL*
Emergency Sampling Under Mitigating Damage Corrective Actions, Lifesaving Actions, Actions----> Emergency to Valuable stop/reduce a 1st Aid, Search and Part of Body Conditions Property release rescue Irradiated Whole Body 5 rem TEDE 10 rem TEDE 25 rem TEDE 25 rem TEDE Skin & any 50 rem SDE 100 rem SDE 250 rem SDE 250 rem SDE Extremity Lens of the Eye 15 rem LDE 30 rem LDE 75 rem LDE 75 rem LDE Any Organ or 50 rem 100 rem 250 rem 250 rem Tissues (CDE+DDE) (CDE+DDE) (CDE+DDE) (CDE+DDE)
NOTES: 1. Radiological Assessment Sampling, includes collection of atmospheric, liquid, and environmental radiological activity samples as well as chemistry samples involving high activity or high radiation. Emergency exposure limits may be authorized for selected individuals, for emergency assessment functions, in addition to annual occupational dose to date.
- 2. Property Saving, for example, might be dispatching the Fire Brigade to extinguish a fire in a Very High Radiation Area to protect plant equipment though no immediate threat exists to compromising Plant Safety.
- 3. Dose Saving to Population, includes activities that justify a potential overexposure to a few workers in order to save even a small average dose in a large population. (May also include Traffic Control for Evacuees or other Security Plan Functions.)
- 4. Lifesaving to Individual, includes the activity of search and rescue in very high dose rates or high airborne activity.
- Extreme situations may occur in which a dose in excess of 25 rem TEDE would be unavoidable for either Dose Saving to (Large) Population or Lifesaving to (An)
Individual.
An authorization of emergency exposure with NO LIMITS may be made under those conditions, but only to volunteers who are fully aware of the risks involved, including the numerical levels of dose at which acute effects of radiation will be incurred and the numerical estimates of the risk of delayed effects.

10/07/93 Page 2 of 2 EP RB-2 (UNITS 1 AND 2)
ATTACHMENT 9.6 TITLE: DCPP Emergency Exposure Guidelines NOTES: (Continued)
- 5. If any of the above emergency exposure limits would prevent successful completion of the activity then the RM or SEC should ensure that back-up teams are standing by to rotate in and relieve the primary responders.
- 6. Volunteers for any authorized exposures above 25 rem TEDE should be made aware that there is some risk of acute health effects involved, however remote.
The dose limit of 75 rem to the whole body previously recommended by the EPA for lifesaving action represents a very high level of risk of both acute and delayed effects.
A dose of 100 rem is expected to result in an approximately 15 percent risk of temporary incapacity from non lethal acute effects and an indeterminate, but less than 5 percent, chance of death within 60 days. This is in addition to a risk of about 1 in 30 of incurring fatal cancer.
Such high risk levels can only be accepted by a recipient who has been made aware of the risks involved.
(Reference, EPA Manual of Protective Action Guides and Protective Actions for Nuclear Incidents, May 1992)
NOTE: Although EPA-400 guidelines say that no limit is applicable under extreme situations it is also true that the RM/SEC must make the authorization and may impose a more restrictive limit if so desired consistent with the availability of personnel resources, alternative actions and the desire to avoid acute health effects of the volunteers.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP R-2 NUCLEAR POWER GENERATION REVISION 22 DIABLO CANYON POWER PLANT PAGE 1 OF 6 EMERGENCY PLAN IMPLEMENTING PROCEDURE UNITS TITLE: Release of Airborne Radioactive Materials Initial Assessment 1 2 AND 03/18/04 EFFECTIVE DATE PROCEDURE CLASSIFICATION: QUALITY RELATED
- 1. SCOPE 1.1 This procedure describes the steps to be taken by on-shift personnel to initially evaluate the off-site consequences of an accidental airborne release that may result in Emergency Plan Activation.
1.2 It does not describe the operation of the plant equipment necessary to terminate or minimize the release. This latter subject is covered in the appropriate E, ECA, and FR series Emergency Procedures for the particular release mechanism.
CAUTION: Revisions to this procedure require the PPC display be updated (Reference A0595224).
- 2. DISCUSSION 2.1 An accidental airborne release of radioactive materials that may result in site boundary dose rates in excess of the limits specified in the EP G-1 shall require a prompt initial assessment by the operating staff. This initial release rate and dose assessment is performed using either the Plant Process Computer (PPC) program "EPR2," or manually using Section 7 of this procedure.
2.2 This procedure shall only be used by Control Room personnel to perform initial accident dose assessments. This procedure shall not be used to evaluate compliance with Technical Specification limits during planned effluent releases conducted as part of normal plant operations. The methodology contained in this procedure is intended to provide a rapid and conservative calculation of the projected off-site doses due to an accidental release of airborne radioactive materials. More advanced methodologies are contained in procedures EP RB-9 and EP RB-11 or the appropriate chemistry procedures.
- 3. DEFINITIONS 3.1 Accidental Release - A release of radioactive material unrelated to any planned effluent release evolutions.
3.2 Committed Dose Equivalent (CDE) - The dose to the organs or tissues that would be received from an intake of radioactive material by an individual during the 50 years following the intake.
3.3 Committed Effective Dose Equivalent (CEDE) - The sum of the products of the weighting factors applicable to each of the body organs or tissues that are irradiated and the CDE to these organs or tissues.
3.4 EP R-2.Doc 03B 0119.0419
- UNCONTROLLED PROCEDURE - DO NOT USE TO PERFORM WORK or ISSUE FOR USE ***
PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP R-2 DIABLO CANYON POWER PLANT REVISION 22 PAGE 2 OF 6 TITLE: Release of Airborne Radioactive Materials Initial UNITS 1 AND 2 Assessment Deep Dose Equivalent (DDE) - Dose associated with exposure of the whole body (depth of 1 cm).
3.5 Total Effective Dose Equivalent (TEDE) - The sum of the DDE (for external exposure) and CEDE (for internal exposure).
3.6 TEDE Rate - The time rate of change of Total Effective Dose Equivalent as a function of immersion and inhalation exposure time.
3.7 Thyroid CDE Rate - The time rate of change of Thyroid Committed Dose Equivalent as a function of immersion and inhalation exposure time.
- 4. RESPONSIBILITIES 4.1 Emergency Evaluation Coordinator (EEC) is responsible for performing an initial assessment of an airborne radiological release when directed by the ISEC.
4.2 Interim Site Emergency Coordinator (ISEC) is responsible for determining when an assessment is needed and directing the EEC to implement this procedure based on emergency evaluation priorities.
- 5. PREREQUISITES 5.1 Unified Dose Assessment Center (UDAC) is not activated and performing the function of radiological assessment.
5.2 Interim Site Emergency Coordinator (ISEC) has determined, based on plant accident conditions or symptoms of an accidental radiological release, that an initial assessment of projected off-site doses has priority over other actions being performed by the EEC.
The following listed symptoms indicate that an airborne release may be occurring from within the RCA as guidance to the ISEC:
- There is actual or suspected leakage of water, steam, or noncondensible gases from any vessel or piping system containing primary coolant, liquid radwaste, or gaseous radwaste.
- Damage occurs to a submerged, irradiated fuel assembly with the resultant release of significant quantities of noncondensible gases.
- Alarms occur on CAMs.
- A fire occurs involving radioactive materials.
(Refer to EP M-6)
- Verified alarm on radiation monitors RE-14/14R, RE-28/28R, RE-29, RE-15/15R, or RE-24/24R.
- A major radioactive material spill occurs.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP R-2 DIABLO CANYON POWER PLANT REVISION 22 PAGE 3 OF 6 TITLE: Release of Airborne Radioactive Materials Initial UNITS 1 AND 2 Assessment PRECAUTIONS 6.1 Do not use SPDS to obtain RMS readings. Radiological Monitor readings off SPDS may be based on different units of measurement than required as input to the calculations.
6.2 If the Main Condenser is available during a SGTR event with a stuck open Safety Relief or 10% Steam Dump to atmosphere, there are two release pathways.
6.3 Obtain an independent verification of your calculation whenever time permits to confirm no errors or incorrect assumptions about plant conditions.
6.4 Default release rates are extremely conservative and may result in higher classifications or PARs than would be warranted if actual release indications were available.
6.5 N-16 will be detected on the MSL Radiation Monitors while at power and may cause a false high off-site dose calculation.
6.6 This procedure shall not be used to evaluate compliance to Technical Specifications during planned effluent releases. Such evaluations shall be performed by the Chemistry Department.
6.7 Fuel Handling Accident (FHA) in Containment with Equipment Hatch open is a special case. Use the analyzed default dose rates and doses listed in Attachment 10.1 and go directly to EP G-1 for comparison to the Emergency Action Levels (EALs).
- 7. INSTRUCTIONS NOTE: This calculation can be performed on the PPC using the turn-on code "EPR2."
7.1 RELEASE RATE CALCULATIONS 7.1.1 Obtain a working copy of Attachment 10.1.
7.1.2 Determine release source location as Plant Vent, Atmospheric Steam Release, or Unmonitored.
CAUTION: Do NOT use SPDS to obtain radiation monitor readings.
7.1.3 Gather and record the required information in accordance with the appropriate section of the form.
NOTE: Plant Vent Extended Range Rad Monitor RE-87 will automatically activate if the Normal Range Gas Monitors RE-14/14R approach their maximum reading.
7.1.4 Perform the required calculation to determine the release rate of Total Effluent and record the results in both this Attachment and Attachment 10.2.
7.1.5 If it is not possible to calculate a release rate, refer to the DEFAULT RELEASE RATES on Page 3 of Attachment 10.1 and choose the most appropriate value for input to Attachment 10.2. For an FHA in containment with equipment hatch open, use default dose rates and EP R-2.Doc 03B 0119.0419

- 1. SCOPE 1.1 This procedure describes accident classification guidelines and Emergency Plan activation responsibilities.
- 2. DISCUSSION 2.1 The steps required by this procedure are in addition to the steps required to maintain the plant in, or restore the plant to, a safe condition.
2.2 Events not meeting the minimum classification criteria contained in this procedure should be reviewed for reportability in XI1.ID2, "Regulatory Reporting Requirements and Reporting Process."
2.3 Copies of the Emergency Action Level Classification Chart (Attachment 7.1) are provided as job aids in the following locations: JMC EPIM Office (2), EOF, Recovery Manager Office, TSC Site Emergency Coordinator Office, Unit 1 crash cart, Unit 2 crash cart, and the Simulator crash cart (Ref. OP1.DC23, "Control of Posted Plant Signs and Information").
- 3. DEFINITIONS 3.1 Emergency Classification Levels (ECLs) 3.1.1 Notification of Unusual Event (NUE) - characterized by off-normal conditions that:
- a. May not in themselves be particularly significant from an emergency preparedness standpoint, but could reasonably indicate a potential degradation of the level of safety of the plant if proper action is not taken or if circumstances beyond the control of the operating staff render the situation more serious from a safety stand point. No releases of radioactive material requiring off-site response or monitoring are expected.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP G-1 DIABLO CANYON POWER PLANT REVISION 33B PAGE 2 OF 3 TITLE: Emergency Classification and Emergency Plan Activation UNITS 1 AND 2 3.1.2 Alert - events in progress or having occurred, involving an actual or potentially substantial degradation of the plant safety level.
- a. Small releases of radioactivity may occur (greater than Technical Specification limits for normal operation, but only a small fraction of the EPA Protective Action Guideline (PAG) exposure levels at the site boundary). It is the lowest level where emergency offsite response may be anticipated.
- b. The lowest classification level where off-site emergency response is anticipated.
3.1.3 Site Area Emergency (SAE) - events which are in progress or have occurred involving actual or likely major failures of plant functions needed for protection of the public, but a core meltdown situation is not indicated based on current information.
- a. Any releases are not expected to exceed EPA Protective Action Guides except near the site boundary. However, because the possible release is significant, care must be taken in alerting offsite authorities to distinguish whether the release is merely potential, likely, or actually occurring. Response of offsite authorities will be guided initially by this determination.
3.1.4 General Emergency (GE) - event(s) in progress or having occurred which indicate:
- a. Imminent substantial core degradation or melting.
- b. Potential for containment loss.
- c. Radioactive releases can be reasonably expected to exceed EPA PAGs off-site for more than the immediate area.
- 4. RESPONSIBILITIES 4.1 Interim Site Emergency Coordinator (Interim SEC or ISEC) - Control room shift manager is responsible for initial event classification and emergency plan activation. The ISEC may upgrade the event classification until relieved by either the SEC or RM. In addition, the ISEC may downgrade a NUE to no ECL.
4.2 Site Emergency Coordinator (SEC) - The SEC may upgrade the classification of an event until relieved by the recovery manager.
4.3 Recovery Manager (RM) - The RM, once staffed, is responsible for upgrading or downgrading ECLs, and may direct the SEC to change ECLs.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER EP G-1 DIABLO CANYON POWER PLANT REVISION 33B PAGE 3 OF 3 TITLE: Emergency Classification and Emergency Plan Activation UNITS 1 AND 2 INSTRUCTIONS 5.1 The Interim Site Emergency Coordinator shall:
5.1.1 Initially classify and declare the event using ONLY the guidance in Attachment 7.1 of this procedure.
NOTE: Simultaneous EALs that increase the probability of release require escalation of the ECL to one level above the higher EAL.
5.1.2 Formally announce all emergency classification declarations to the control room, TSC, or EOF, respectively.
5.2 The ISEC or SEC may:
5.2.1 Upgrade the event to a higher ECL until the recovery manager arrives at and assumes responsibility in the EOF. However, the ISEC and SEC shall not downgrade an event classified at the Alert or higher level at any time. The ISEC may downgrade a NUE to no ECL.
5.2.2 Only the recovery manager may downgrade an ECL at the Alert or higher level according to the most current controlling EAL.

PACIFIC GAS AND ELECTRIC COMPANY NUMBER EOP ECA-0.3 DIABLO CANYON POWER PLANT REVISION 12 PAGE 27 OF 29 TITLE: Restore 4KV Buses UNIT 1 APPENDIX X CROSSTIE OF VITAL BUS SCOPE Implementation of this Appendix requires approval of the Site Emergency Coordinator. This Appendix should be performed to energize two vital buses from one diesel. If two vital buses are energized, enough ESF equipment should be energized to establish one ESF train.
DISCUSSION As a general guideline, in this situation several options may be available depending on plant conditions and RCS status. If SI is not required, the Shift Foreman may elect to stay in a hot shutdown status awaiting restoration of off-site power or he may decide to cooldown. If SI is required, a minimum of one ECCS flow path must be established. The type of ECCS flowpath desired would depend on RCS conditions.
PRECAUTIONS AND LIMITATIONS
- 1. Some equipment may have to be operated on a continuous basis and some on an "as needed" basis. Existing conditions will determine which equipment is needed (plant cooldown, SI, etc.).
- 2. The maximum capacity of the diesel generator should not be exceeded. Appendix Q identifies the diesel generator load limits. Appendix Q, Table 1 provides loads for various vital 4KV and 480 vital equipment. STP M-9M also contains specific loads on all 480 volt vital equipment.
- 3. The DG that is to be used is assumed to be supplying its own vital bus and running in Auto. The DG should remain in Auto during the performance of this procedure to allow the Isoc feature to maintain proper frequency. If manual is used the operator will need to make frequency adjustments as the DG is loaded.
PROCEDURE
- 1. Obtain permission from the Site Emergency Coordinator.
- 2. On the deenergized bus being reenergized, verify ALL the breakers AND DC control power switches are OPEN for the following loads AND ALL the 480V Breakers are open. This prevents automatic loading and overloading the diesel. Continue with steps 3 through 10 while performing this step.

- 3. Cutin the D/G DIR PWR, LOSS OF FIELD & BKR OC PROT RLYS C/O SW for the diesel generator selected to supply power to the deenergized bus.
- 4. Reset SI (if applicable) so that the affected bus will not try to auto load when the bus becomes energized.
- 5. Cutout the AUTO Transfer FCO's for 4KV buses and 12KV buses.
NOTE: If the D/G associated with the deenergized bus is running but will not load on the bus, it must be shutdown to permit the Auto Transfer Relay to be reset.
- 6. Depress all AUTO Transfer Reset Push Buttons, verify the BLUE lights go OUT.
- 7. Verify OPEN all vital bus 4KV auxiliary feeder breakers, 52-HH-13, 52-HG-13 and 52-HF-13.
- 8. Verify OPEN all vital bus 4KV startup feeder breakers, 52-HH-14, 52-HG-14 and 52-HF-14.
- 9. Verify OPEN startup feeder breaker 52-HG-15, to the vital buses F, G and H.

DEENERGIZED BUS FEEDER BREAKER F 52-HF-10 G 52-HG-10 H 52-HH-10 CAUTION: o The breaker alignment in step 2 must be completed prior to performing Step 11.
o If the diesel generator appears unstable at any time beyond this point in the procedure, immediately open startup feeder breaker for the operable bus to separate the diesel from the inoperable bus.
NOTE: Although the DG will not be synchronized with other buses during the performance of these steps, most of the breakers to be closed will require the sync key to be on.
- 11. CLOSE the 4KV startup feeder breaker for the deenergized bus being reenergized.

- 1. SCOPE 1.1 This procedure is used in Mode 5 or 6 when it is apparent that the electrical buses needed for effective Decay Heat Removal are not energized and measures more complex than closing or reclosing the bus feeder breakers are required.
1.2 This procedure may be entered from Shutdown Emergency Procedure OP AP SD-0, or directly when the loss of AC power is recognized.
1.3 This procedure provides guidance for regaining AC power to the Vital 4kV buses and the Nonvital 4kV buses.
1.3.1 The possible Recovery power sources are:
- a. Steps 2 and 3 - Affected Unit's Aux Power system
- b. Steps 5 and 6 - Affected Unit's SU Power system
- c. Steps 8 and 9 - Other Unit's SU Power system
- d. Steps 11 thru 16 - Other Unit's Aux Power system
- e. Appendix X - Cross-tie of Vital buses using an operating Diesel Generator
- f. Appendix N - Energizing Non-Vital buses using an operating Diesel Generator 1.3.2 The selection of the best Recovery power source will depend on factors that are impossible to predict during an outage, therefore it is not necessary to select the Recovery power source in the order given in this procedure. The shift foreman may choose not to use a Recovery power source, the procedure reader may then assume that power source is not available and follow the instructions in the Response not Obtained column to get to the implementation instructions for the Recovery power source of choice.
- 2. SYMPTOMS 2.1 Loss of AC power to any required electrical bus.

- 1. SCOPE 1.1 Implementation of the Appendix requires approval of the Site Emergency Coordinator or his designate. This Appendix should be performed to energize two vital buses from one diesel. If two vital buses are energized, enough ESF equipment should be energized to establish effective Decay Heat Removal.
- 2. DISCUSSION 2.1 As a general guideline, in this situation several options may be available depending on plant conditions and RCS status.
- 3. PREREQUISITES 3.1 Verify all the breakers AND DC control power switches are OPEN for the 4kV loads AND ALL 480V Breakers are racked out on the deenergized bus being reenergized to prevent automatic loading and overloading the diesel. Refer to list below:

- 4. PRECAUTIONS AND LIMITATIONS 4.1 Some equipment may have to be operated on a continuous basis and some on an "as needed" basis. Existing conditions will determine which equipment is needed.
4.2 The maximum capacity of the diesel generator should not be exceeded.
Appendix Q identifies the diesel generator load limits. Table 1 provides loads for various vital 4kV and 480V vital equipment. STP M-9M also contains specific loads on all 480V vital equipment.
4.3 Start only one piece of equipment at a time, allowing at least 4 seconds between each start, since starting current may cause bus failure.

5.13 Operate only the equipment needed for the existing conditions. Evaluate the load on the diesel generator prior to energizing each additional load to ensure its capacity limit is not exceeded REFER TO APPENDIX Q. Note that this curve is based on the number of hours the diesel was operated in an overloaded condition, not total run hours. Refer to Table 1 to identify the expected maximum loads for each piece of equipment. If the diesel overloads, it may only be necessary to trip the last load added rather than the entire bus.
NOTE: Battery chargers are necessary within two hours to ensure continued instrument AC power.

3.2 Chemistry is responsible for sampling, as required.
- 4. PREREQUISITES 4.1 Applicable portions of OP B-1A:IX , "CVCS - Alignment Verification For Plant Startup" have been completed.
4.2 The 4% Boric Acid System is in normal operation.
4.3 Primary Water System is in normal operation.
4.4 A charging pump (either reciprocating or centrifugal) is in service.
4.5 If performing section 6.10, a sealed component change form has been prepared for CVCS-1-8428.
- 5. PRECAUTIONS AND LIMITATIONS 5.1 When boric acid is supplied to the charging system, the flow shall be routed through FCV-110B directly to the charging pump suction. This is necessary since the flowpath to the VCT (FCV-111B) is only partially heat traced. Routing boric acid through this flowpath can result in crystallization of the boric acid and plugging of the volume control tank spray nozzle. If on Excess Letdown, boric acid in concentrations RCS boron may be directed through FCV-111B per section 6.14 of this procedure.
5.2 When volume control tank pressure is increased above the normal range due to level increases, volume control tank pressure and reactor coolant pump No. 1 seal leakoff flows should be monitored. The VCT should be vented to the vent header continuously during significant level increases by opening CVCS-1-8101, "VCT to Vent Hdr Isol Vlv."
5.3 Prior to operations requiring large amounts of makeup, the Gaseous Radwaste System should be verified in service with a Waste Gas Compressor operating.
5.4 Equalization of boron concentration between the RCS and the Pressurizer shall be initiated for major boration/dilution evolutions (i.e. greater than 50 PPM change). The difference in boron concentration between the RCS and Pressurizer should not exceed 50 PPM.
5.5 Towards EOL, when the automatic makeup mode is selected, consideration should be given for maintaining the control switch for FCV-110A in the closed position.
5.6 Review the following Technical Specifications/ECG items:
5.6.1 ECG 8.8 Borated Water Sources - Shutdown 5.6.2 ECG 8.9 Borated Water Sources - Operating 5.6.3 T.S. 3.5.4 Refueling Water Storage Tank 00122533.DOC 02 1203.0704

PACIFIC GAS AND ELECTRIC COMPANY NUMBER OP B-1A:VII DIABLO CANYON POWER PLANT REVISION 33A PAGE 3 OF 39 TITLE: CVCS - Makeup Control System Operation UNIT 1 5.7 The chemistry technician should be notified whenever RCS makeup addition
> 2000 gal/day is anticipated.
5.8 Following major (greater than 50 PPM change) dilution/boration evolutions, the actual RCS boron concentration should be determined by sampling and compared to the expected value prior to any additional boration or dilution evolutions.
5.9 When changing the setting of the batch integrators, the proper setting should be verified prior to initiating boration or dilution.
5.10 When operating with Hagan controllers (HC-110 and HC-111) in manual, CVCS make up deviation alarm and subsequent termination of the selected operation may occur if the potentiometer on the selected Hagan controller is not adjusted to the actual flow achieved, as set by the manual push buttons (30 second time delay). The tolerance is +/- 0.8 gpm for boric acid flow and +/- 5.0 gpm for primary flow.
5.11 The boric acid integrator will stop counting if the flowrate falls below 0.4 gpm and the primary water integrator will stop counting if the flowrate falls below 2.0 gpm. This prevents spurious counts if the flow transmitter output does not fall to exactly zero when the system is shutdown.
5.12 One or two extra gallons of boric acid may be added at the end of borations due to the time it takes for FCV-110A to stroke closed.
5.13 Two or three extra gallons of water may be added at the end of dilutions due to the time it takes for FCV-110B to stroke closed.
5.14 Sections of this procedure will prevent automatic makeup to the VCT during the evolution. VCT level should be monitored closely to ensure expected response is obtained.
5.15 Some sections of this procedure require manual operation of controllers or control switches. Failure to restore the system to normal following these evolutions may result in unplanned reactivity additions.
5.16 Consider potential changes in reactivity that could occur due to actions taken in this procedure, and perform a reactivity brief if required by the Reactivity Management Program.

- 1. SCOPE 1.1 This procedure provides instructions for relatching the Steam-Driven Auxiliary Feed Pump Turbine, and returning it to service.
- 2. DISCUSSION 2.1 The following sections should be used as applicable after an overspeed trip of the auxiliary feed pump turbine:
Section 6.1 - Restart of the Steam-Driven Auxiliary Feed Pump After an Overspeed Trip Section 6.2 - Make the Steam-Driven Auxiliary Feed Pump Available After an Overspeed Trip
- 3. RESPONSIBILITIES 3.1 The shift foreman (SFM) is responsible for proper alignment and operation of equipment discussed in this procedure.
- 4. PREREQUISITES 4.1 The following systems should be in service:
4.1.1 Main steam supply to AFW Pump 1-1 via FCV-37 and FCV-38.
AFW Pump 1-1 is operable only if it is capable of being powered from two operable and redundant steam supply sources.
4.1.2 Condensate Storage Tank or alternate auxiliary feedwater supply. (Refer to OP D-1:V.)
- 5. PRECAUTIONS AND LIMITATIONS 5.1 Review Technical Specifications 3.7.5 and 3.7.6.
5.2 If the turbine room fills with an excessive amount of steam, the oil in the turbine bearings and pump bearings should be changed and sampled for water. An excessive amount of steam would be enough to condense and drip onto the floor such that the better part of the pump room floor is slick or has puddles.
5.3 If the MSIVs are isolated, ensure that the steam traps upstream of the MSIVs are in service with the MSIV bypass valves open for loops 2 and 3. If the air operated MSIV bypass valves can not be opened, locally open the manual bypass valves. If the steam traps for loops 2 and 3 cannot be placed in service, declare AFW Pump 1-1 INOPERABLE, and close FCV-37 and FCV-38.
5.4 If AFW PP 1-1 turbine relief valve RV-57 is found to be lifting, investigate for possible obstruction in the turbine exhaust path.

- 6. INSTRUCTIONS 6.1 Restart of the Steam-Driven Auxiliary Feedwater Pump After an Overspeed Trip 6.1.1 Verify that the speed setting knob on the turbine governor MS-1-FCV-15 is positioned to the maximum speed setting (fully clockwise).
6.1.2 Turn the turbine throttle trip valve MS-1-FCV-152 handwheel in the clockwise direction until the spring is fully compressed.
6.1.3 Latch up the latching lever by means of the trip hook.
6.1.4 Ensure the trip mechanism on top of the bearing housing has been properly reset per Attachment 9.1.
NOTE: This is accomplished by pulling the connecting rod slightly towards the trip valve (FCV-152) while pushing down on the trip tappet and nut. Once the tappet nut is properly seated, gently release tension applied to connecting rod.
6.1.5 Open MS-1-FCV-152 fully by turning the handwheel in the counterclockwise direction.
NOTE: The turbine will roll up to speed as the handwheel is turned in the counterclockwise direction. The governor should come into action to maintain full speed (approximately 4150-4240 RPM). If the turbine again trips on overspeed, reperform steps 6.1.1 through 6.1.4, then open the throttle trip valve handwheel only until full speed is attained. RPM indication is both local and in the Control Room. If manual throttling of MS-1-FCV-152 is required, this indicates a failure of the Woodward Governor.
6.1.6 Leave the throttle trip valve in the latched position.
6.2 Make the Steam-Driven Auxiliary Feed Pump Available After an Overspeed Trip 6.2.1 Verify that plant conditions do not require restart of the Steam-Driven Auxiliary Feedwater Pump.
6.2.2 Close MS-1-FCV-95, Turbine Steam Inlet Valve.
6.2.3 Slowly open MS-1-950, Trap 118 Bypass Valve, to verify steam bypass line is depressurized (refer to PRECAUTIONS section).
6.2.4 Turn the turbine throttle trip valve MS-1-FCV-152 handwheel in the clockwise direction until the spring is fully compressed.
6.2.5 Latch up the latching lever by means of the trip hook.
