{{#Wiki_filter:HATCH UNIT 1 TRM T 11.0-1 T 11.0 LOSS OF FUNCTION DIAGRAMS A. Purpose Loss of Function Diagrams (LFDs) provide a means for evaluating the affects of the loss of one or more instrument channels on the capability of the associated instrument logic to perform its intended safety function. In fulfilling this purpose, the LFDs provide the following: The number of channels associated with a given instrument function. The configuration of the instrument channels in the trip systems. The number and combinations of channels required to be operable in order for instrument function capability to be maintained. B. General Rules for Use: LFDs are channel-based, that is, they are designed to be used to determine instrument function capability given a loss of one or more channels. For the purposes of determining loss of function, the LFDs show what constitutes a channel. However, in identifying the beginning and end of a channel for the purpose of determining channel functional test scope, the LFD should not be used for this purpose; instead, the TRM definition Channel Functional Test Scope should be used. As in typical elementary logic, the energy trace is from the sensor to the actuated device. Consequently, inoperability of a component in the energy trace can directly or indirectly affect the ability of a downstream component in the trace to function. However, the opposite is not always true; that is, the downstream component since it does not provide input to the upstream component does not affect the ability of the upstream component to function. As such, loss of a component anywhere other than in the channel cannot in all cases be traced back to evaluate the affect of the loss on a channel(s). Consequently, since the LFDs are channel-based, in such cases, the LFD cannot be used to determine instrument function capability. Instead, the elementary logic must be consulted to determine the affect of the loss on the supported system. LFDs are designed to be used with the instrumentation specifications found in the Technical Specifications, the TRM, and the ODCM. Typically, an LFD is provided for each instrumentation specification line item. However, some instruments provide more than one instrument function and an LFD may not provide sufficient information to ascertain all of the functions provided by the instrument. In order to identify all instrument functions performed by a particular instrument, Table 10.1-1, Master Equipment Cross Reference, Sorted by MPL, must be consulted. For a given MPL, this sort will identify all LFDs for the instrument functions that are served by the instrument. The complete logic from sensor to the actuation logic/actuated device is not reflected in the LFDs. A dashed line is used to denote cases where the logic
HATCH UNIT 1 TRM T 11.0-2 was not included. Elementary diagrams used to develop the LFD are referenced on the LFD in the event information on the omitted logic is needed. The drawings show the channels and the trip logics associated with a particular instrument function and how the channels and the trip logics are related in the trip systems. The LFDs are ordered alphabetically by the system abbreviation and then sequentially by the sketch number. The LFD sketches are condensed elementaries and, therefore, the same rules of use that apply to elementaries also apply to the LFDs. The loss of function statement typically found at the bottom of the LFD identifies the channel combinations required to be operable in order for instrument function capability as defined in the instrumentation specification to be maintained. In some cases, the associated instrument specification contains an action statement that requires tripping the inoperable channel within a prescribed period of time. The LFD takes credit for this requirement in that it specifies for these cases that in order for instrument function to be maintained, the prescribed combinations of channels must be either operable or maintained in the tripped condition. The following is a list of abbreviations and their meanings used in the drawings that may be unfamiliar to the user: AU - Alarm Unit EPM - RPS Electric Power Monitoring ITU - Indicating Trip Unit LRM - Log Radiation Monitor MTU - Master Trip Unit PRM - Process Radiation Monitoring PS - Pressure Switch RWLH - Reactor Water Level High RIS - Radiation Indicating Switch SAU - Single Alarm Unit STU - Slave Trip Unit

- No timer is associated with the "A" division start signal for pump Ell-C002C, consequently, even if channel "B4" is inoperable, pump El 1-C002C is still capable of being started provided the "A" division initiation logic is operable.
Minimum Channel Requirements for System Initiation Capability: In order to maintain LPCI initiation capability with regard to the LPCI Pump Start Timers, one of the following combinations of channels is required to be operable: (Al or Bl) and(* orB4) or (A2 or B2) and (A3 or B3) It is noted that when a timer fails such that it would actuate faster than required, the possibility exists of the pump associated with the failed timer overloading the associated Emergency Diesel Generator thereby affecting two low pressure ECCS pumps unless the pump is prevented from starting.

HATCH UNIT 1 TRM T 12.0-1 Revision 1 T 12.0 Safety Function Determination Program 1.0 Introduction This document outlines the Plant Hatch Safety Function Determination Program (SFDP), provides guidance for evaluating the impact of failure to meet multiple Technical Specifications (TS) Limiting Conditions for Operation (LCOs), and gives appropriate actions for a loss of safety function. The SFDP is required by TS Section 5.5.10. 2.0 Loss of Safety Function
2.1 Background
LCO 3.0.2 directs that if an LCO is not met, its associated Required Actions shall be performed. LCO 3.0.6 provides exception to LCO 3.0.2 for a supported system, structure, or component (SSC) by allowing only the support SSC LCO Actions to be performed if the supported SSC is inoperable solely because its support SSC is inoperable. If a support SSC is inoperable and a loss of safety function does not exist, the Required Actions for the support SSC address the Condition, and the supported SSC Required Actions do not have to be performed. This recognizes that the plant may no longer satisfy single failure criteria and that all of the supported SSC may not meet the definition of OPERABILITY. Appropriate compensation is made by performance of the support system Required Actions. 2.2 Use of LCO 3.0.6 Upon determination that a TS required support SSC is inoperable, the decision may be made to use LCO 3.0.6 for the supported SSCs. A loss of safety function determination shall be performed using the flow chart shown in Attachment 1 as a guide. Attachment 2 provides examples of appropriate determinations. The allowances given by LCO 3.0.6 can be taken only if no loss of safety function exists. 2.3 Actions for a Loss of Safety Function 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. These may be the Required Actions specified for the loss of safety function or LCO 3.0.3.
HATCH UNIT 1 TRM T 12.0-2 Revision 1 2.4 SSC OPERABILITY OPERABILITY determinations precede entry into the SFDP and thus, are not a direct part of the SFDP. OPERABILITY of an SSC is determined using the definition given in TS 1.1, along with the guidance of SR 3.0.1. When equipment that is not addressed in TS is degraded or nonconforming, the impact on TS SSC OPERABILITY shall also be assessed. 3.0 Guidance for Safety Function Determination TS 5.5.10 states that a loss of safety function exists when, assuming no concurrent single failure, a safety function assumed in the accident analyses cannot be performed. For the purpose of this program a graduated approach may be taken for determining the safety function of the supported SSC. This approach, detailed below, is graduated from most to least conservative. Even if the least conservative method is used, the requirements of TS 5.5.10 will be met. In determining whether a loss of safety function has occurred, at least one of these methods must be used. Method 1: Redundant Train(a) For this method, the safety function is assumed to be the system function. Confirm the OPERABILITY of the corresponding redundant supported SSC(s). If one or more of the redundant SSCs are found to be inoperable, a loss of safety function may exist. The appropriate actions for a loss of function may be taken or alternatively, one of the following methods may be used. Method 2: LCO Function In certain cases, multiple systems with diverse individual functions are specified under one LCO statement; i.e., in one TS. For these, the safety function may be considered to be broader than the individual system function--it is the TS LCO function, not the system function. An example of this is the TS for ECCS Operating, in which four different systems are included. In this case, the function as stated in the Bases,... to cool the core during a LOCA, may be the safety function to be considered in the SFDP. If a loss of LCO function is determined to exist, the appropriate actions for a loss of safety function may be taken. Alternatively, the following method may be used. (a) The term train may be interchanged with subsystem or division.
HATCH UNIT 1 TRM T 12.0-3 Revision 1 Method 3: Safety Analysis In this approach, the function of the SSC in the FSAR accident analyses is considered to be the safety function. If the SSC in question is not credited in the analyses, or if the accident function it performs is intact, then no loss of safety function exists. However, if the function is lost, then the actions for a loss of safety function must be taken. 4.0 Additional Requirements and Information 4.1 Non-TS SSCs A situation may exist where a TS support SSC provides support to an SSC not addressed in TS, which may in turn support a supported SSC addressed in TS. The interrelationships between TS and non-TS support and supported SSCs shall be considered in the loss of safety function determination. 4.2 Subsequent Inoperabilities While taking the Required Actions of the support SSC as allowed by LCO 3.0.6, the impact of subsequent additional SSC inoperabilities on previous SFDP evaluations shall be considered. 5.0 Extending Supported SCS Completion Times 5.1 Singular Support SSC Inoperability When entering the supporting SSC Required Actions as allowed by LCO 3.0.6, the Completion Times for the supported SSCs might potentially be extended longer than their allowed Required Action Completion Times if they are shorter than those of the support SSC. If there is no loss of safety function, it is acceptable to extend the Completion Time of the supported SSC an amount equal to but not exceeding the Completion Time of its support SSC. 5.2 Multiple Support SSC Inoperabilities Once a supported SSC LCO is not met solely based on a support SSC inoperability, subsequent support SSC inoperabilities have additional limitations. This is to ensure that the supported LCO will not be in a situation of not being met for an inappropriate amount of time. Provided there is no loss of function, the Required Actions of the support SSC Condition(s) continue to apply to each additional failure, with Completion Times based on initial entry into the particular support SSC Condition. However, when a subsequent support SSC is discovered to be inoperable or not within limits, the overall time that the supported SSC LCO is not met shall be limited to the more restrictive of either:
- a. The first support SSC Completion Time, plus an additional 24 hours; or
HATCH UNIT 1 TRM T 12.0-4 Revision 1
- b. The subsequent support SSC Completion Time as measured from discovery of the subsequent inoperability.
To apply this Completion Time extension, two criteria must first be met. The subsequent support SSC inoperability.
- a. Must exist concurrently with the first inoperability; and
- b. Must remain inoperable or not within limits after the first inoperability is resolved.
Should this extended Completion Time expire with the subsequent support SSC remaining inoperable or not within limits, the Completion Time for the subsequent support SSC inoperable Condition shall be considered expired. The Required Actions defined for that Condition shall be entered. Examples regarding Completion Time tracking are included in Attachment 2. 6.0 Conclusions Regarding the Use of LCO 3.0.6 The exception permitted by LCO 3.0.6 is justified as follows. The actions necessary to ensure safe operation of the plant are specified in the support SSC LCO Required Actions and the SFDP requires evaluation of loss of safety function. The SFDP directs that appropriate actions be taken if a loss of safety function exists. This approach eliminates the confusion and inconsistency associated with entry into multiple LCO Conditions and Required Actions.
HATCH UNIT 1 TRM T 12.0-5 Revision 5 ATTACHMENT 1 (Sheet 1 of 2)
HATCH UNIT 1 TRM T 12.0-6 ATTACHMENT 1 (Sheet 2 of 2)
HATCH UNIT 1 TRM T 12.0-7 ATTACHMENT 2 SCENARIO NO. 1: At 0100, with Unit 2 in RUN, the Unit 2 4160V F bus (a.k.a. swing bus) is determined to be inoperable. No other TS SSC inoperabilities exist. The 4160V F bus is a support SSC, addressed by TS LCO 3.8.7. Required Action C requires restoring the bus to OPERABLE status within 8 hours. The following is the loss of function determination for the supported systems: RHR Pumps 2C and 2D: For LCO 3.5.1, because Core Spray, ADS, and HPCI are OPERABLE, no loss of safety function exists. RHR Pumps 2C and 2D: For LCO 3.6.2.3, suppression pool cooling is not considered inoperable because only one pump per subsystem is required. RHR Pumps 2C and 2D: For LCO 3.6.2.4, suppression pool spray is not considered inoperable because only one pump per subsystem is required. RHR Pump 2C: For LCO 3.7.1, because the other subsystem is OPERABLE, no loss of safety function exists. PSW Pumps 2C and 2D: For LCO 3.7.2, because PSW can perform its safety function with one pump per subsystem, no loss of safety function exists. CRD Pump 2B: This is a non-TS SSC, but it supports control rods, TS LCO 3.1.3. With redundant CRD pumps operable, the safety function of the control rods is not affected. Diesel Bldg. MCC 1B (1R24S026): This is part of the 4160V F bus subsystem, addressed by TS 3.8.7. This supports distribution cabinet 1K (1R24S030) and ultimately the DG 1B. The DG 1B is inoperable, and LCO 3.8.1 Condition B required several different actions with Completion Times ranging from 1 hour to 7 days. With redundant DGs OPERABLE, no loss of safety function exists.
== Conclusions:== No loss of safety function exists. LCO 3.0.6 may be entered with a completion time of 8 hours to restore the inoperable bus to OPERABLE status, beginning at 0100.
HATCH UNIT 1 TRM T 12.0-8 Revision 35 SCENARIO NO. 2: At 0500, with Unit 2 in RUN, Reactor Vessel Water Level-Low Low Low (Level 1) channels A, B, and C are determined to be inoperable. This leaves only channel D operable. This instrumentation supports ECCS by providing initiation for Core Spray, LPCI and ADS; and, also, supports initiation of the DGs and isolation of the PSW Turbine Building valves. Since all these supported functions require at least two channels, entry must be made into the Required Actions for LCO 3.3.5.1. These Actions directly specify declaring supported features inoperable (due to loss of initiation capability in both Divisions). As stated in LCO 3.0.6, when the support SSC Required Actions provide direction for supported SSCs, the applicable supported SSC Conditions and Required Actions shall be entered. This effectively precludes the use of LCO 3.0.6 in determining the completion time for the supported SSCs.
== Conclusions:== The LCO 3.3.5.1 Required Actions should be performed, as well as those for all the inoperable supported systems. The SFDP will not be entered, because LCO 3.0.6 cannot be used. SCENARIO NO. 4-A: At 0100, with Unit 2 in MODE 1, the Unit 2 RHRSW A Pump becomes inoperable. The RHRSW crosstie valves are tagged for maintenance. No other TS SSC inoperabilities exist. The RHRSW system is a support SSC, addressed by TS LCO 3.7.1. Required Action A for one inoperable RHRSW pump is to restore the pump to OPERABLE status within 30 days. The bases for this specification state that an RHRSW subsystem is considered operable when 2 pumps are OPERABLE with an OPERABLE flow path. With the A pump inoperable, the A subsystem of RHRSW is inoperable. The following is the loss of function determination for the supported systems: RHR Suppression Pool Cooling: LCO 3.6.2.3 requires two subsystems to be OPERABLE for suppression pool cooling. The Bases for this LCO state that an RHR suppression pool cooling subsystem is OPERABLE with one RHR pump, the heat exchanger, and associated piping. Therefore, the inoperability of RHRSW subsystem A causes suppression pool cooling subsystem A to be inoperable. This is Condition A, with a Required Action Completion Time of 7 days. However, because suppression pool cooling subsystem B is OPERABLE, no loss of safety function exists. The Completion Time for suppression pool cooling may be extended to 30 days (from the time of discovery of RHRSW pump A being inoperable; i.e., 0100). RHR Suppression Pool Spray: LCO 3.6.2.4 requires 2 subsystems to be OPERABLE for suppression pool spray. The Bases for this LCO state that an RHR suppression pool spray subsystem is OPERABLE with one RHR pump, the heat exchanger, and associated piping. Therefore, the inoperability of RHRSW subsystem A causes suppression pool spray subsystem A to be inoperable. This is Condition A, with a Required Action Completion Time of 7 days. However,
HATCH UNIT 1 TRM T 12.0-9 Revision 35 because subsystem B is operable, no loss of safety function exists. The Completion Time for suppression pool spray may be extended to 30 days. SCENARIO 4-B: At 29 days, 2 hours after the initial inoperability of RHRSW pump A, with the pump remaining inoperable, RHRSW pump C is found to be inoperable. At 29 days 6 hours, RHR SW pump A is restored to OPERABLE status. RHRSW pump C remains inoperable. With the second RHRSW pump inoperability, Condition C has been entered for LCO 3.7.1. Note that the Completion Time clock for Condition A is still running. Condition C requires that the RHRSW subsystem be restored to OPERABLE status within 7 days. The two SSCs supported by RHRSW continue to have their B subsystems OPERABLE, so no loss of safety function exists. When the RHRSW pump A is restored to OPERABLE status, the LCO 3.7.1 Condition C is exited, but the Condition A clock is still running due to the inoperability of RHRSW pump C. Under the provisions of Section 1.3 of the Technical Specifications, the Completion Time for RHRSW pump C is 31 days from the initial inoperability, i.e., the inoperability of pump A. Therefore, the Completion Times for the supported SSCs may also be extended to 31 days measured from the same starting point.}}
