OU-AA-103 Revision 15 Page 3 of 24 SHUTDOWN SAFETY MANAGEMENT PROGRAM

1.

PURPOSE 1.1 This procedure defines the Nuclear Shutdown Safety Assessment and Management Program (SSMP).

1.2 This procedure applies to the planning, scheduling, and execution of work on a unit already in or expected to be in a shutdown mode of operation. The actual periods of applicability are determined on a site-specific basis in conjunction with the site's On-line Risk process.

1.3 This procedure applies to units in shutdown operation Salem modes 3,4,5,6, defueled or Hope Creek modes 3,4,5, defueled.other than Salem modes 1, 2, 3 or Hope Creek modes 1, 2.

2.

TERMS AND DEFINITIONS

2.1 Available

For the purpose of this procedure a system, structure or component (SSC) along with its necessary auxiliary systems, controls, instrumentation and power supplies is capable of performing its intended function and can be placed in service by manual (simple operator actions) or automatic means within the required timeframe.

2.1.1.

Simple Operator Actions are actions an operator can take that require no support such as closing in a breaker or opening a manual valve. When considering the use of simple operator actions the time required to place the system or component in service to maintain the key safety function should be considered. Actions that require the use of more than 50% of the available time required to maintain the key safety function should not be considered.

2.1.2.

A system or component does not have to be operable as defined in Technical Specifications to be considered available.

2.1.3.

A system or component cannot be considered available if its functionality has been removed ( i.e. clearance applied, drained, breached, etc )

2.1.4.

A clearance, for Operations only, on the power supply breaker for a component is acceptable provided the release paperwork is pre-staged and the field operator has received a pre job brief on the removal of the tag and subsequent closure of the breaker.

2.1.5.

Credit may be taken for temporary alterations (i.e. power supplies), and line-ups provided procedural guidance is available.

OU-AA-103 Revision 15 Page 4 of 24 2.1.6.

Any equipment supporting shutdown safety key safety functions is required to be tested, validating its functionality, prior to the time it is required to be available to support reduced defense in depth.

2.2 Unavailability

Not meeting the availability guidelines.

2.3 Containment Closure: The action to secure primary (PWR) or secondary (BWR) containment and its associated structures, systems, and components as a functional barrier to fission product release under existing plant conditions.

2.4 Contingency Plan: A plan of compensatory actions to:

Maintain Defense-in-Depth by alternate means when pre-outage planning reveals that specified systems, structures, or components will be unavailable.

Restore Defense-in-Depth when system availability drops below the planned Defense-in-Depth during the outage.

Minimize the likelihood of a loss of Key Safety Functions during higher-risk evolutions.

Provide response actions for postulated events that would present a challenge to Key Safety Functions.

2.5 Decay Heat Removal Capability: The ability to maintain reactor coolant system and spent fuel pool temperature and/or pressure below specified limits following a shutdown.

2.6 Defense-in-Depth

For the purpose of managing risk during shutdown, Defense-in-Depth is the concept of providing systems, structures, and components to ensure backup of Key Safety Functions using redundant, alternate, or diverse methods. INPO 06-008 provides additional guidance and philosophy

2.7 Defueled

All fuel assemblies removed from the reactor vessel.

2.8 First Time Evolution: Those activities (affecting Shutdown Safety) that have never been conducted on the equipment.

2.9 Forced Outages: Any outage that requires unit shutdown and entry into modes of operation for which the SSMP is applicable, and were not identified and planned at least one month in advance of the outage.

2.10 High Risk Activity: Activities, plant configurations, or conditions during shutdown where the plant is more susceptible to an event causing the loss or challenge to a Key Safety Function.

OU-AA-103 Revision 15 Page 5 of 24 2.11 High Risk Activity Review: An evaluation of all planned or emergent activities for the purpose of determining the effects of these activities on the Key Safety Functions. Items to be considered when reviewing these activities, as applicable, shall include:

Work that affects equipment or plant configurations associated with a Key Safety Function as defined by the site-specific procedures.

Work that is outside of an established clearance boundary.

Work that could cause an undesirable equipment actuation.

Work that involves equipment that could indirectly impact equipment or plant configurations associated with Key Safety Functions (Instrument Air, Ventilation, heat sink, etc.).

Work on other equipment that is in close proximity to equipment associated with Key Safety Functions.

Rigging and/or transport of heavy loads over equipment associated with Key Safety Functions 2.12 Inventory Control: Measures established to ensure that irradiated fuel assemblies remain adequately covered to maintain heat transfer and shielding capabilities.

2.13 Salem Key Safety Functions:

Decay Heat Removal Electric Power Availability (both On-site and Off Site)

Inventory Control Reactivity Control Spent Fuel Pool Cooling

- Containment Service Water SWGR Pen Area Cooling

- CREACS Control Air

OU-AA-103 Revision 15 Page 6 of 24 2.14 Hope Creek Key Safety Functions:

- Shutdown Cooling Electrical Power Availability (both On-site and Off Site)

- Inventory Control

- Secondary Containment

- Reactivity Control Spent Fuel Pool Cooling 2.15 Limiting Condition for Operation (LCO) 3.0.4.b: LCO 3.0.4.b allows entry into a MODE or other specified condition in the Applicability with inoperable equipment required by TS, provided that a risk assessment demonstrates the acceptability. The risk assessment shall address all inoperable systems and components, consideration of the results, determination of the acceptability of entering the MODE or other specified condition in the Applicability, and establishment of risk management actions, if appropriate. The use of LCO 3.0.4.b is subject to the following limitations.

LCO 3.0.4.b should not be used unless there is a reasonable probability of completing restoration such that the requirement of the LCO would be met prior to the expiration of the ACTION Completion Times that would require exiting the Applicability.

The risk assessment must consider all unavailable TS equipment. The risk impact of inoperable TS equipment not covered by the current risk assessment tools must be qualitatively assessed.

The use of LCO 3.0.4.b is prohibited for certain systems. Refer to station TS.

2.16 ORAM-SENTINEL: A computer-based tool, which is used to assess the Risk Levels associated with plant configurations and outage activities during both the planning and execution phases of the outage. The program uses imported information from the outage schedule or manual user input to calculate the associated risk levels 2.17 Equipment Out of Service (EOOS): A software tool that allows online work activity schedules to be analyzed for the impact on Nuclear Safety. The program receives input from the scheduling tool as well a manually entered parameters.

EOOS process the activity through a Salem or Hope Creek specific model and calculates the overall effects on the nuclear Safety. EOOS uses a probabilistic model and calculates core damage frequency.

OU-AA-103 Revision 15 Page 7 of 24 2.18 Protected Equipment: Equipment (or systems) whose availability has been physically identified as essential to ensure that a Key Safety Function is maintained.

2.19 Pathway (Pathway to Success): A process, power system/train, or plant condition, which helps to maintain one or more Key Safety Functions.

2.20 Protected Pathway: A pathway whose availability has been identified as essential to ensure that a Key Safety Function is maintained.

2.21 Reactivity Control: Measures established to preclude inadvertent criticality, power excursions or losses of shutdown margin, and to predict and monitor core behavior.

2.22 Reduced Inventory (PWR): Water level in the reactor vessel is greater than 3 feet below the reactor vessel flange and fuel in the vessel.

2.23 Lowered Inventory (PWR): Level at or below the vessel flange (independent of RPV head status) and fuel in the vessel.

2.24 Lowered Inventory (BWR): Level at the flange, fuel in the vessel and RPV head detensioned.

2.25 Schedule Changes: A schedule change as it relates to the SSMP is an alteration in the sequencing for removal / restoration of equipment or an alteration in the sequencing of plant configuration changes for those activities that support Key Safety Functions and thus alters their relationship from the previously approved schedule. Shifting of equipment removal / restoration or plant configuration changes forward or backward in time does not constitute a schedule change as long as their relationship to the previously approved sequence in the outage network remains intact.

2.26 Shutdown Safety Categories: The nature of the risk, which is to be evaluated by the assignment of a deterministic Status (color) and/or by the calculation of a probabilistic status. There are four such categories:

Key Safety Function Status: The color of an individual Key Safety Function.

Unit Status: The overall color for the unit as defined in the site-specific procedure.

Planned Status: The "as planned color of a Key Safety Function or Unit Status.

Actual Status: The color of a Key Safety Function or Unit Status resulting from the "as executed" actual plant conditions.

OU-AA-103 Revision 15 Page 8 of 24 2.27 Safety Status (colors): The results of the safety evaluation deterministically from the SFATs and /or probabilistically from the PSSA or PRA as applicable.

These evaluations are made the individual Key Safety Functions. A four-color Safety Status scheme is used which is explicitly defined for each site in their site-specific procedure. A computed color for a Key Safety Function corresponds to the following safety status:

GREEN: Based on the combination of available pathways and activity types a failure or error could be easily mitigated without presenting a significant challenge in that Key Safety Function. This represents optimal defense-in-depth with all or nearly all mitigation equipment available.

YELLOW: Based on the combination of available pathways and activity types a failure or error can still be mitigated but might present a challenge in that Key Safety Function. This represents reduced defense-in-depth with more than the minimum pathways available.

ORANGE: Based on the combination of available pathways and activity types a failure or error would potentially lead to the loss of the Key Safety Function. This represents no defense-in-depth.

RED: Based on the combination of available pathways and activity types the Key Safety Function is potentially not maintained. This represents a condition in which the safety function is not supported relative to its success criteria.

2.28 Switchyard Work: Work in the Switchyard(s) that significantly increases the potential for initiating a Loss of Off-Site Power (LOP) event, or loss of power to a component that may affect shutdown safety.

2.29 System Windows: Time periods during the outage when work on systems or a train is scheduled, and they may be unavailable or degraded.

2.30 Time to Boil: Given the plant configuration, decay heat load, and location of the fuel from the previous operating cycle, the time it would take to reach bulk coolant saturation temperature with no Decay Heat Removal systems in operation. Consider the reactor and spent fuel pool separately or as one body depending on plant conditions.

2.31 Time to Uncover the Core: Given the plant configuration, decay heat load, and location of the fuel from the previous operating cycle, the time it would take to reduce the reactor vessel inventory to the top of active fuel.

OU-AA-103 Revision 15 Page 14 of 24 4.2.3. Evolutions resulting in reduced inventory should be considered and executed as infrequently performed evolutions IAW HU-AA-1211.

4.2.4.

The availability of systems should be controlled and documented through an approved process or as documented by the SSRB. For those instances where a system is neither drained or disassembled, if the Shutdown Safety Review Board (SSRB) determines that the system or component can be returned to service in the required time, they may declare that the system or component is available after documenting the rationale and approving it using Attachment 1 of this procedure.

4.2.5.

Outage management will conduct a High Risk Activity review, documented in SAP, which will include all of the following:

Work that affects equipment or plant configurations associated with a Key Safety Function as defined by the site-specific procedures.

Work that is outside of an established clearance boundary.

Work that could cause an undesirable equipment actuation.

One in-service decay heat removal train and required support systems with fuel in the reactor vessel, One reactor inventory makeup train and required support systems with fuel in the vessel, One spent fuel pool cooling train once core offload starts until the time to boil in the spent fuel pool is greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

4.5.5.

The SSRB reviews and approves the plan to protect equipment 4.5.6.

A list of protected equipment is required for any entry into ORANGE condition.

Protected equipment may also be required for YELLOW conditions as identified by the SSRB. 4.5.7.

The Shutdown Safety Manager or designee reviews the schedule during the outage execution and revises, if necessary, the Protected Pathways list if plant configuration and equipment availability require these changes.

4.5.8.

The Shift Manager will receive the list of Protected Pathways 4.5.9.

The Shift Manager ensures that the appropriate Protected Pathways signs/barriers have been placed on a shiftly basis or whenever the requirements change.

4.5.10.

The protected train concept is applicable for switchyard work and associated off-site power feeds, relays, switchgear and associated transformers. This work includes activities performed by station personnel, supplemental workers and Transmission and Distribution employees.

4.5.11.

Work on Protected Equipment (in or within 2 feet of the area posted) that could result in the loss of the supported safety function will be evaluated and approved by the Shift Manager IAW OP-AA-108-116.

4.5.12.

Protected path signs have been established to provide consistency throughout PSEG.

4.6 Contingency Plans 4.6.1.

All entries into Status ORANGE require a Contingency Plan containing the following elements:

OU-AA-103 Revision 15 Page 20 of 24 All associated work instructions and procedures are reviewed and approved and necessary equipment and parts are staged Roles and responsibilities for implementing contingency actions are outlined for workers, the outage control center (OCC) staff, and control room personnel. Individuals are identified in advance and contact lists are maintained with a pre-determined communication protocol for initiating contingency actions.

Walkthroughs and drills are conducted to validate contingency plan assumptions, where feasible. For example, time critical operation and maintenance activities such as placing gravity feed in service, powering a bus from a blackout diesel, establishing temporary power feeds, or closing the containment equipment hatch are determined.

4.6.2.

The SSRB may select and approve additional activities or plant configurations that require a Contingency Plan.

4.6.3.

Any contingency plans that were developed to support SSMP requirements will be approved by the SSRB. 4.6.4.

When developing Contingency Plans, the use of permanent and/or temporary equipment, procedures, and additional monitoring and controls is acceptable.

Consider plant conditions such as time to core boil/damage, decay heat loads, time to perform the Contingency Plan and installed or temporary equipment.

4.6.5.

A Contingency Plan will clearly state when it is applicable to ensure it is in place when required.

4.6.6.

Contingency Plans will be distributed to work groups having actions to perform if the plan is activated. The work groups, as appropriate, will brief these actions while the plan is in place.

4.7 Post Outage Assessment 4.7.1.

Upon completion of a Refueling Outage and for other outages as determined by the SSRB, a post outage assessment report will be prepared and issued to the Plant Manager.

4.7.2. The report will focus on the following:

Compare Planned Status with Actual Status encountered during the execution of the outage.

Identify unplanned entries into status Yellow, Orange, or Red.

Disposition unplanned unavailability of Shutdown Safety Equipment during periods when it was needed to support Key Safety Functions.

OU-AA-103 Revision 15 Page 21 of 24 4.8 Shutdown Safety Management Program Site Specific Procedures 4.8.1.

Each plant will have a site-specific procedure providing detailed guidance for implementation of the SSMP based on individual site characteristics.

4.8.2.

Each site ensures all shutdown safety evaluations are conducted in accordance with the policies and practices contained in OU-HC/SA-105.(Q).

4.9 Site Specific Procedure Contents 4.9.1.

Each Site Specific procedure will contain as a minimum the following:

Safety System Status sheet that can be used to verify that actual plant configuration matches the planned configuration.

Safety System Outage Guidelines that provide minimum Defense-in-Depth requirements for each Key Safety Function.

A Program or data sheet that provides a method for performing a manual safety assessment.
