TLCO Applicability TRM 3.0.100 T3.0 TRM LIMITING CONDITION FOR OPERATION (TLCO) APPLICABILITY TLCO 3.0.100.1 TLCOs shall be met during the MODES or other specified conditions in the Applicability, except as provided in TLCO 3.0.100.2.

TLCO 3.0.100.2 Upon discovery of a failure to meet a TLCO, the Required Actions within the TRM of the associated Conditions shall be met, except as provided in TLCO 3.0.100.5.

Failure to meet a TLCO may require initiation of an operability determination to determine the impact of the failure on equipment contained within the Technical Specifications.

If the TLCO is met or is no longer applicable prior to expiration of the specified Completion Time(s), completion of the Required Action(s) is not required, unless otherwise stated.

TLCO 3.0.100.3 When a TLCO is not met and the associated ACTIONS are not met, an associated ACTION is not provided, or if directed by the associated ACTIONS, action shall be initiated immediately to communicate the situation to the Shift Manager and document the condition in accordance with the PVNGS corrective action program. An initial decision on whether the unit can continue to operate with the condition shall be completed within 7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months . Further actions shall be as required by the corrective action disposition and as deemed necessary by plant management.

Exceptions to this Specification are stated in the individual Specifications.

Where corrective measures are completed that permit operation in accordance with the TLCO or ACTIONS, completion of the actions required by TLCO 3.0.100.3 is not required.

TLCO 3.0.100.3 is only applicable in MODES 1, 2, 3, and 4.

TLCO Applicability TRM 3.0.100 T3.0 TLCO APPLICABILITY (continued)

TLCO 3.0.100.4 When a TLCO is not met, entry into a MODE or other specified condition in the Applicability shall only be made:

a. When the associated ACTIONS to be entered permit continued operation in the MODE or other specified condition in the Applicability for an unlimited period of time; or

b. After performance of a risk assessment addressing 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; exceptions to this Specification are stated in the individual Specifications, or

c. When an allowance is stated in the individual value, parameter, or other Specification.

This Specification shall not prevent changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit.

TLCO 3.0.100.5 Equipment removed from service or declared inoperable to comply with ACTIONS may be returned to service under administrative control solely to perform testing required to demonstrate its OPERABILITY or the OPERABILITY of other equipment. This is an exception to TLCO 3.0.100.2 for the system returned to service under administrative control to perform the testing required to demonstrate OPERABILITY.

TSR Applicability TRM 3.0.100 TRM SURVEILLANCE REQUIREMENT (TSR) APPLICABILITY TSR 3.0.100.1 TSRs shall be met during the MODES or other specified conditions in the Applicability for individual TLCOs, unless otherwise stated in the TSR. Failure to meet a TSR, whether such failure is experienced during the performance of the TSR or between performances of the TSR, may require initiation of an operability determination to determine the impact of the failure on equipment contained within the Technical Specifications. Failure to perform a TSR within the specified Frequency shall be failure to meet the TLCO except as provided in TSR 3.0.100.3. TSRs do not have to be performed on inoperable equipment or variables outside specified limits.

TSR 3.0.100.2 The specified Frequency for each TSR is met if the TSR is performed within 1.25 times the interval specified in the Frequency, as measured from the previous performance or as measured from the time a specified condition of the Frequency is met.

For Frequencies specified as "once," the above interval extension does not apply.

b. The structural integrity of the tendons shall be demonstrated by:

1. Determining from a random but representative sample of at least 10 tendons (6 hoop and 4 inverted U) that each group (

hoop, and inverted U) has an observed lift-off force within the predicted limits for that group. For each subsequent inspection one tendon from each group shall be kept unchanged to develop a history and to correlate the observed data. The procedure of inspection and the tendon acceptance criteria shall be as follows:

(a) If the measured prestressing force of the selected tendon in a group lies above the prescribed lower limit, the lift-off test is considered to be a positive indication of the sample tendon's acceptability; (b) If the measured prestressing force of the selected tendon in a group lies between the prescribed lower limit and 90% of the prescribed lower limit, two tendons, one on each side of this tendon, shall be checked for their prestressing forces. If the prestressing forces of these two tendons are above 95%

of the prescribed lower limits for tendons, all three tendons shall be restored to the required level of integrity, and the tendon group shall be considered acceptable. If the measured prestressing force of any two tendons falls below 95% of the prescribed lower limits of the tendons, additional lift-off testing shall be done to detect the cause and extent of such occurrence; (c) If the measured prestressing force of any tendon lies below 90% of the prescribed lower limit, the defective tendon shall be completely detensioned and additional lift-off testing shall be performed to determine the cause and extent of such occurrence; (continued)

(d) If the average of all measured prestressing forces for each group (corrected for average condition) is found to be less than the minimum required prestress level at anchorage location for that group, the condition shall be considered as below the acceptance criteria for containment vessel structural integrity; and (e) Unless there is degradation of the containment vessel below the acceptance criteria during the first three inspections, the sample population for subsequent inspections shall include at least 6 tendons (3 hoop and 3 inverted U).

2. Performing tendon detensioning, inspections, and material tests on a previously stressed tendon from each group. A randomly selected tendon from each group shall be completely detensioned in order to identify broken or damaged wires. A previously stressed tendon wire or strands from one tendon of each group shall be removed for testing and examination over the entire length to determine (which should include the broken wire if so identified) that:

(a) The tendon wires are free of corrosion, cracks, and damage; (b) There are no changes in the presence or physical appearance of the sheathing filler-grease; and (c) A minimum tensile strength of 240,000 psi (guaranteed ultimate strength of the tendon material) exists for at least three wire samples (one from each end and one at mid-length) cut from each removed wire. Failure of any one of the wire samples to meet the minimum tensile strength test is evidenced that structural integrity is below the acceptance criteria.

3. Performing tendon retensioning of those tendons detensioned for inspection to at least force level recorded prior to detensioning or the predicted value, whichever is greater, with the tolerance within minus zero to plus 6%, except that (continued)

During retensioning of these tendons, the stress in the tendon shall not exceed 80% of its ultimate strength, and the changes in load and elongation shall be measured simultaneously at a minimum of three approximately equally spaced levels of force between zero and the seating force.

If the elongation corresponding to a specific load differs by more than 10% from that recorded during installation, an investigation shall be made to ensure that the difference is not related to wire failures or slips of wires in anchorages; and

4. Verifying the OPERABILITY of the sheathing filler-grease by assuring:

(a) No voids in excess of 5% of the net duct volume, (b) Minimum grease coverage exists for the different parts of the anchorage system, and (c) The chemical properties of the filler material are within the tolerance limits specified as follows:

Water content 0 - 5% by wt.

Chlorides 0 - 10 ppm Nitrates 0 - 10 ppm Sulfides 0 - 5 ppm Reserved Alkalinity 0 - 50% of the installed value (Base Numbers) (installed value 0 - 5 for older grease)

c. As an assurance of the structural integrity of the containment vessel, tendon anchorage assembly hardware (such as bearing plates, stressing washers, wedges, and buttonheads) of all tendons selected for inspection shall be visually examined.

A functional boration "system" consists of a borated water source, a gravity-fed suction pathway, a pump capable of being powered from an emergency power supply, and a discharge path to the RCS.

Use of redundant components within the chemical and volume control, safety injection, and spent fuel pool cooling systems enhances flexibility and reliability in meeting design requirements.

Soluble boron in the reactor coolant and control rods provide two diverse methods of core reactivity control. In accordance with the provisions of GDC 26, boration systems can reliably control the rate of reactivity changes resulting from planned, normal power changes, including xenon burnout, without exceeding acceptable fuel design limits. Each boration system is capable of maintaining the temperature-dependent shutdown margin and KN-1 requirements of the Technical Specifications during a cooldown. In addition, each boration system can add the boron equivalent of 4% k/k, not including the effects of xenon, during a plant cooldown to mode 5 considering only the borated makeup water used to compensate for thermal contraction of the coolant. Under normal conditions with letdown in service, the boration systems are also capable of making the core subcritical from a hot operating condition and holding it subcritical in the hot standby condition. In the event that Technical Specification shutdown margin requirements are not met during normal operations, the associated action statements direct the operator to initiate boration and continue until margins are restored. One boration system can add 1% k/k of (continued)

In accordance with GDC 33, boration systems can supply reactor coolant makeup for protection against breaks in small lines connected to the reactor coolant pressure boundary. Small lines, such as those for instrument and sample connections, contain flow orifices to limit leakage rates within the capacity of available charging pumps. As part of the normal makeup, the boration systems assure that specified acceptable fuel design limits are not exceeded as a result of minor reactor coolant leakage with or without offsite electrical power.

GDC 10 and GDC 19 require in part that the reactor coolant system be designed with appropriate margin and controls to assure that specified acceptable fuel design limits are not exceeded during normal operation and anticipated operational occurrences. The operability of boration systems ensures that primary system pressure and inventory (pressurizer level) can be adequately controlled following a loss of offsite power and subsequent cooldown to cold shutdown conditions. In combination with the shutdown cooling system, boration systems are capable of supporting a natural circulation cooldown in accordance with the requirements of Branch Technical Position (BTP) RSB 5-1 as accepted for PVNGS as a Class 2 plant.

APPLICABLE None of the accidents analyzed in chapter 15 of the safety SAFETY analysis report require charging or auxiliary spray for ANALYSIS mitigation of the event. The boration systems support general design requirements, and verification that the systems can perform their safety functions is contained in design calculations separate from the accident analyses. Although these calculations are conservative with respect to expected system capability, they are based on nominal system conditions/performance, and the effects of instrument uncertainty are not included. The results of these analyses are summarized in UFSAR 9.3.4. Additional requirements and (continued)

In addition to performance requirements, the general design criteria also place limits on the damage possible from malfunctions of the boration systems. GDC 28 requires that the rate of reactivity addition be limited so that postulated reactivity accidents do not result in yielding of reactor coolant pressure boundary materials or deformation of fuel and vessel internals that may impair core cooling. This is verified in part by the UFSAR 15.4.6 analysis for inadvertent deboration. Boration systems may also affect GDC 15, which requires that reactor coolant pressure boundary design limits shall not be exceeded during normal or anticipated operational occurrences. UFSAR 15.5.2 shows that charging pump flow is low enough to ensure that the bounding pressurizer level control system malfunction will not overpressurize the primary system.

LCO The OPERABILITY of the boration systems ensures the capability to control reactivity during power changes, maintain shutdown margin requirements, makeup for reduction in reactor coolant volume due to contraction and nominal system losses, makeup for losses due to small breaks in the RCS pressure boundary, provide reactor coolant pump seal injection, and control reactor coolant pressure through the use of auxiliary spray when required.

The charging pumps have a design flow of approximately 44 gpm, but pump inefficiencies result in a nominal charging pump discharge flow of about 42 gpm. Because of the nature of positive displacement pumps, the pump discharge flow rate does not vary significantly with reactor coolant system pressure.

The net charging flow is the total charging pump discharge flow minus the reactor coolant pump controlled bleed-off flow, which does not enter the reactor coolant system. With two pumps required to be OPERABLE, the minimum net charging flow of 26 gpm for a single pump ensures that the boron injection rate described in the basis of the Technical Specifications can be provided even in the event of a single failure. In addition, the nominal charging flow from a single pump provides adequate (continued)

Lastly, the OPERABILITY of two charging pumps ensures that the system can mitigate the effects of a small break in the reactor coolant system. Consideration of a single failure is not required in support of GDC 33, and the nominal net charging rate of 68 gpm from two charging pumps (i.e., 26 gpm + 42 gpm) exceeds the maximum break flow and provides sufficient makeup to prevent violation of fuel design limits during the subsequent controlled cooldown.

An OPERABLE charging pump must be powered from an OPERABLE ESF bus that can be energized from either an offsite circuit or an emergency diesel generator. Use of safety grade power supplies in combination with gravity-fed flow suction pathways provides a high level of assurance of boration system function during normal operations and following a loss of offsite power.

Requiring two of three boration flowpaths to be OPERABLE provides a high probability that at least one pathway will be available to connect the borated water source to the charging pump suction. All of the specified pathways are gravity-fed and therefore do not require use of non-class pumps to provide net positive suction head for the charging pumps. Since the VCT boron concentration is normally much less than 4000 ppm and the tank may be pressurized with a noncondensible gas, the two pathways that utilize the normal charging pump suction are not OPERABLE unless VCT outlet valve CH-501 can be closed.

Although not specified, the availability of an additional flow path from the charging pump discharge to the RCS is implied.

Actions outside the control room have been acknowledged in aligning the flowpaths. The specified flowpaths are neither fully safety grade nor single failure proof. However, the probability of a single-point vulnerability failing when called upon is low. In addition, high-pressure safety injection in combination with the reactor coolant head vents provides a diverse method of accomplishing the boration safety functions.

Overall this results in an acceptable level of functional reliability for the boration systems.

The Refueling Water Tank (RWT) is required per Technical Specifications to be OPERABLE in MODES 1-4 in order to provide an adequate supply of borated water for emergency core cooling systems in the event of a LOCA. The minimum RWT level required in the Technical Specifications ensures that sufficient volume is available above the high suction nozzle in order to conduct a natural circulation cooldown in accordance with the provisions of BTP RSB 5-1. That minimum level also provides adequate borated make-up for a small line break and all credited reactivity control functions. The Spent Fuel Pool (SFP) is also required to be OPERABLE in MODES 1-4 as a redundant borated water source to protect against single failure for the emergency boration function. In other analyses, failure of the RWT as a passive, seismic class 1, safety grade component is not a credible malfunction.

A cold shutdown reserve volume (CSDRV) is maintained to compensate for the change in reactor coolant volume that results from thermal contraction during cooldown to cold shutdown entry conditions with RCP controlled bleed-off isolated. The CSDRV also bounds the volumes of borated water required for postulated reactivity events. The minimum volumes required for both the RWT and SFP provide a high degree of reliability with respect to the reactivity control and safe shutdown capabilities. To account for depletion of makeup inventory during cooldown, the cold shutdown reserve volume requirements vary as a function of cold leg temperature. Once the primary has been cooled to cold shutdown conditions, borated water inventory is only required to makeup for further contraction during continued cool down to refueling conditions and to refill the pressurizer.

The requirements on temperature and boron concentration of the borated water sources are consistent with the values used in safety analysis and reactivity calculations. The upper limit spent fuel pool temperature is 180°F; however, the 2%

difference in density between water at 120° and 180° has negligible impact on the required volume of makeup water or its reactivity worth.

APPLICABILITY The normal makeup system contains three charging pumps, all of which are normally in service. With the RCS temperature above 210°F, a minimum of two charging pumps is required to mitigate the effects of a small line break over all of the expected operating pressures. A minimum of two boron injection systems is also required to ensure single functional capability in those events where an assumed failure renders one of the systems inoperable. With the RCS temperature below 210°F, one system is acceptable without single failure consideration based on the stable reactivity condition of the reactor and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity changes.

In MODES 1-4, charging pumps are required in order to accomplish boron injection over the full range of expected reactor coolant system pressure. The provision of three charging pumps when only two are required provides for maintenance and flexibility of operation. In modes 5 and 6, the safety grade high pressure and low pressure safety injection pumps are capable of delivering the required flow rates. Since they are also energized from an emergency power supply, they are acceptable alternatives if a charging pump is not OPERABLE at low system pressures.

This time allows for minor component repair or corrective action without undue risk of overall facility safety during the repair period. If restoration can not be accomplished in 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months , enter TLCO 3.0.100.3 and initiate corrective action in accordance with PVNGS corrective action program and initiate an operability determination, as necessary to determine the impact on equipment in the technical specifications. This should include an assessment of the plant configuration and a determination of the appropriate compensatory action and/or Mode changes to maintain safe operation and compliance with design and licensing basis.

In MODES 5-6, the absence of an OPERABLE boration method represents a serious degradation in reactivity management controls. Suspension of core alterations and positive reactivity additions preclude the need for emergency boration until control can be re-established.

SURVEILLANCE Surveillance tests for the RWT in the Technical Specifications REQUIREMENTS as a supply of emergency core cooling water are more restrictive than those as a borated water source. Since SFP is as stable as the RWT with respect to temperature, level (volume), and boron concentration, the prescribed testing frequency is the same as for the RWT.

Based on operational experience, monthly verification of manual valve position in the boration flowpaths provides reasonable assurance that the system will function as designed, and remedial operator actions outside the control room in addition to those needed to normally align the system are not needed to initiate flow.

The charging pumps and valves in the boration flow paths are tested in accordance with the station in-service testing program.

T3.1.204 Shutdown CEA Insertion Limits and T3.1.205 Regulating CEA Insertion Limits Safety analysis assumes that the Shutdown and Regulating Groups 1 & 2 CEAs are fully withdrawn any time the reactor is critical. This ensures that:

a. The minimum shutdown margin (SDM) is maintained; and

b. The potential effects of a CEA ejection accident are limited to acceptable limits.

CEAs are considered fully withdrawn at 147.75 inches (Pulse Counter indication) and 145.25 inches (RSPT indication) since this position supports the assumptions made in the safety analysis. The required CEA insertion position, as indicated by the RSPT, differs from the required CEA insertion position, as indicated by the Pulse Counter, to allow for the inaccuracies associated with the RSPT. The actual CEA position is required to be > 147.75 inches withdrawn and the Pulse Counter indication is considered to be the most accurate. Additionally, a CEA at its UEL (Upper Electrical Limit) satisfies the requirement for > 147.75 inches withdrawn.

Due to fuel design changes (Guardian Grid fuel assemblies), the active height of the core was raised resulting in the need for a higher fully withdrawn CEA position in order to maintain the active portion of the CEAs in a position supported by the safety analysis. Shutdown and Regulating Groups 1 & 2 CEAs are required to be fully withdrawn to meet the SDM requirements of the safety analysis. The CEA all rods out (ARO) position specified by the Core Data Book supports the CEA Guide Tube Wear Program, is a variable position based upon core life and does not violate the fully withdrawn CEA position required for the safety analysis SDM requirements.

An AZIMUTHAL POWER TILT greater than the limit specified in the CORE OPERATING LIMITS REPORT with COLSS in service or 0.03 with COLSS out of service is not expected and if it should occur, operation is restricted to only those conditions required to identify the cause of the tilt. The tilt is normally calculated by COLSS. A minimum core power of 20%

of RATED THERMAL POWER is assumed by the CPCs in its input to COLSS for calculation of AZIMUTHAL POWER TILT. The 20% RATED THERMAL POWER threshold is due to the neutron flux detector system being inaccurate below 20% core power.

Core noise level at low power is too large to obtain usable detector readings.

The surveillance requirements specified when COLSS is out of service provide an acceptable means of detecting the presence of a steady-state tilt. It is necessary to explicitly account for power asymmetries because the radial peaking factors used in the core power distribution calculations are based on an untilted power distribution.

The AZIMUTHAL POWER TILT is equal to (Ptilt/Puntilt)-1.0 where:

AZIMUTHAL POWER TILT is measured by assuming that the ratio of the power at any core location in the presence of a tilt to the untilted power at the location is of the form:

The OPERABILITY of these systems is required to provide the overall reliability, redundancy, and diversity assumed available in the facility design for the protection and mitigation of accident and transient conditions.

The integrated operation of each of these systems is consistent with the assumptions used in the safety analyses.

The quarterly frequency for the channel functional tests for these systems is based on the analyses presented in the NRC approved topical report CEN-327-A, "RPS/ESFAS Extended Test Interval Evaluation," and CEN-327-A, Supplement 1, and calculation 13-JC-SB-200-Rev. 01.

The verification of response time at the specified frequencies provides assurance that the protective and ESF action function associated with each channel is completed within the time limit assumed in the safety analyses. The instrumentation response times are made up of the time to generate the trip signal at the detector (sensor response time) and the time for the signal to interrupt power to the CEA drive mechanism (signal or trip delay time).

Response time may be verified by any series of sequential, overlapping or total channel measurements, including allocated sensor response time, such that the response time is verified.

During movement of irradiated fuel assemblies in the fuel building with the required FBEVAS channel inoperable, an OPERABLE FBEVS train must be immediately placed in the emergency mode of operation (i.e., fan running, valves/dampers aligned to the post-FBEVAS mode, etc.) or movement of irradiated fuel assemblies must be suspended immediately. The first action ensures that no undetected failures preventing FBEVS system operation will occur, and that any active failure will be readily detected. If an OPERABLE FBEVS train is not placed in the emergency mode of operation, this action requires suspension of the movement of irradiated fuel assemblies in order to minimize the risk of release of radioactivity that might require the actuation FBEVS. This does not preclude the movement of fuel to a safe position.

Movement of spent fuel casks containing irradiated fuel assemblies is not within the scope of the Applicability of this technical specification.

Reactor Coolant System vents are provided to exhaust noncondensible gases and/or steam from the primary system that could inhibit natural circulation core cooling. The OPERABILITY of at least one Reactor Coolant System vent path from the reactor vessel head ensures the capability exists to perform this function.

A vent path is the flow capability from the reactor vessel head to the reactor drain tank (RDT) or from the reactor vessel head to containment atmosphere.

The four vent paths are:

1. From the reactor vessel head through solenoid operated valve (SOV) HV-101, then through SOV HV-105 to the RDT.

2. From the reactor vessel head through SOV HV-101, then through SOV HV-106 directly to containment atmosphere.

3. From the reactor vessel head through SOV HV-102, then through SOV HV-105 to the RDT.

4. From the reactor vessel head through SOV HV-102, then through SOV HV-106 directly to containment atmosphere.

The valve redundancy of the Reactor Coolant System vent paths serves to minimize the probability of inadvertent or irreversible actuation while ensuring that a single failure of a vent valve, power supply, or control system does not prevent isolation of the vent path.

The function, capabilities, and testing requirements of the Reactor Coolant System vent systems are consistent with the requirements of Item II.B.1 of NUREG-0737.

T3.5.201 Shutdown Cooling System The OPERABILITY of two separate and independent shutdown cooling subsystems ensures that the capability of initiating shutdown cooling exists when required assuming the most limiting single failure occurs. The requirement to verify the functionality of an inoperable shutdown cooling subsystem minimizes the time exposure of the plant to an event requiring shutdown concurrent with the failure of a component on the other shutdown cooling subsystem.

The shutdown cooling subsystem operation is described in UFSAR 5.4.7. Many of the components comprising the shutdown cooling system have specific requirements during Modes 1-3 in the Technical Specifications (e.g., emergency core cooling, containment spray, and containment isolation). However, several components do not have specific operability requirements in Technical Specifications, and some components function differently in their shutdown cooling role than they do when performing the other functions required by Technical Specifications. These factors must be considered when determining the OPERABILITY and/or functionality of the shutdown cooling subsystems.

The safety analysis assumes that shutdown cooling may be placed in operation once cold leg temperature is less than or equal to 350°F and pressurizer pressure is less than approximately 400 psia. Additional information (continued)

TRM Specification Bases TRM 6.0.100 TRM SPECIFICATION BASES regarding the shutdown cooling system is in UFSAR Section 9.3.4. Since the subsystem is manually initiated, temporary changes in the position of shutdown cooling system valves from their normal line up do not necessarily make them inoperable with respect to their shutdown cooling safety function.

The action for one shutdown cooling subsystem inoperable requires verification that the inoperable subsystem is still functional. Functionality requires the subsystem to be capable of performing its safety function given a transient (e.g. Small Break LOCA, SGTR). Functionality will be established utilizing the Operability Determination Program. The allowed outage time is consistent with the durations permitted for those major shutdown cooling components whose operability is controlled by Technical Specifications. The specified outage time allows a reasonable opportunity to effect repairs while providing acceptable limits for the duration of intervals where the system may not be OPERABLE. In combination with the maintenance rule requirements in 10 CFR 50.65, the allowed outage times help ensure that the shutdown cooling subsystems will be functional when required.

If the subsystem cannot be restored or functionality verified within the stated time frame, the associated ACTION places the unit in Mode 4 where the steam generators are still available for heat removal and the stored energy of the NSSS is much less than it is during power operation. While in Modes 3 and 4 continued actions to restore the subsystem to OPERABLE are required.

The action for both shutdown cooling subsystems inoperable require verification of functionality of at least one subsystem within 7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months . The shorter duration is consistent with the increased safety consequences that exist when the equipment required to establish cold shutdown conditions is inoperable. If at least one subsystem cannot be restored or verified functional within 7 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months , the associated ACTION again places the unit in Mode 4 where the steam generators are available for heat removal and the stored energy in the NSSS is minimized. While in Mode 3 and 4 continued actions to restore the required subsystems to OPERABLE are required.

The surveillance requirement to place each train of shutdown cooling in service every refueling interval demonstrates that the subsystems are functional. In combination with other testing performed to support Technical Specifications, including that conducted as part of the in-service testing and inspection programs, the specified surveillances provide reasonable assurance that the system will be able to perform its intended safety functions.

T3.6.300 Hydrogen Recombiners BACKGROUND The function of the hydrogen recombiners is to eliminate the potential breach of containment due to a hydrogen oxygen reaction. Per 10 CFR 50.44, "Standards for Combustible Gas Control Systems in Light-Water-Cooled Reactors" (Ref. 1),

and 10 CFR 50, GDC 41, "Containment Atmosphere Cleanup" (Ref. 2), hydrogen recombiners are required to reduce the hydrogen concentration in the containment following a Loss Of Coolant Accident (LOCA) or Main Steam Line Break (MSLB).

The recombiners accomplish this by recombining hydrogen and oxygen to form water vapor. The vapor remains in containment, thus eliminating any discharge to the environment. The hydrogen recombiners are manually initiated since flammability limits would not be reached until several days after a Design Basis Accident (DBA).

Two 100% capacity independent hydrogen recombiners are shared among the three units. Each consists of controls, a power supply, and a recombiner located in the Auxiliary Building. Recombination is accomplished by heating a hydrogen air mixture above 1150°F. The resulting water vapor and discharge gases are cooled prior to discharge from the recombiner. Air flows through the unit at 50 cfm with a 5 hp centrifugal blower in the unit providing the motive force. A single recombiner is capable of maintaining the hydrogen concentration in containment below the 4.0 volume percent (v/o) flammability limit. Two recombiners are provided to meet the requirement for redundancy and independence. Each recombiner is powered from a separate Engineered Safety Features bus.

PALO VERDE UNITS 1, 2, 3 T6.0.100-21 Rev 53 11/10/10

TRM Specification Bases TRM 6.0.100 TRM SPECIFICATION BASES APPLICABLE The hydrogen recombiners provide for controlling the bulk SAFETY ANALYSES hydrogen concentration in containment to less than the (continued) lower flammable concentration of 4.0 v/o following a DBA.

This control would prevent a containment wide hydrogen burn, thus ensuring the pressure and temperature assumed in the analysis are not exceeded and minimizing damage to safety related equipment located in containment. The limiting DBA relative to hydrogen generation is a LOCA.

Hydrogen may accumulate within containment following a LOCA as a result of:

a. A metal steam reaction between the zirconium fuel rod cladding and the reactor coolant;

b. Radiolytic decomposition of water in the Reactor Coolant System (RCS) and the containment sump;

c. Hydrogen in the RCS at the time of the LOCA (i.e.,

hydrogen dissolved in the reactor coolant and hydrogen gas in the pressurizer vapor space); or

d. Corrosion of metals exposed to Containment Spray System and Emergency Core Cooling Systems solutions.

To evaluate the potential for hydrogen accumulation in containment following a LOCA, the hydrogen generation as a function of time following the initiation of the accident is calculated. Conservative assumptions recommended in Reference 3 are used to maximize the amount of hydrogen calculated.

TLCO Two hydrogen recombiners shared among the three units must be OPERABLE. This ensures operation of at least one hydrogen recombiner in the event of a worst case single active failure.

Operation with at least one hydrogen recombiner ensures that the post LOCA hydrogen concentration can be prevented from exceeding the flammability limit.

In MODES 3 and 4, both the hydrogen production rate and the total hydrogen produced after a LOCA would be less than that calculated for the DBA LOCA. Also, because of the limited time in these MODES, the probability of an accident requiring the hydrogen recombiners is low. Therefore, the hydrogen recombiners are not required in MODE 3 or 4.

In MODES 5 and 6, the probability and consequences of a LOCA are low, due to the pressure and temperature limitations. Therefore, hydrogen recombiners are not required in these MODES.

ACTIONS The required ACTIONS have been modified by a Note stating that all three PVNGS Units (Units 1, 2, and 3) shall simultaneously comply with the REQUIRED ACTION(s) when the shared portion of the hydrogen recombiner(s) is the cause of a CONDITION. This is necessary since the three PVNGS Units share the two hydrogen recombiners that are required by this LCO. It will be necessary for the Control Room of the Palo Verde Unit that discovers an inoperable shared portion of the hydrogen recombiner(s) to notify the other two Palo Verde Unit's Control Rooms of the inoperability.

A.1 With one containment hydrogen recombiner inoperable, the inoperable recombiner must be restored to OPERABLE status within 30 days. In this condition, the remaining OPERABLE hydrogen recombiner is adequate to perform the hydrogen control function. The 30 day Completion Time is based on the availability of the other hydrogen recombiner, the small probability of a LOCA or MSLB occurring (that would generate an amount of hydrogen that exceeds the flammability limit),

and the amount of time available after a LOCA or MSLB (should one occur) for operator action to prevent hydrogen accumulation from exceeding the flammability limit.

Both the initial verification and all subsequent verifications may be performed as an administrative check, by examining logs or other information to determine the availability of the alternate hydrogen control system. It does not mean to perform the Surveillances needed to demonstrate OPERABILITY of the alternate hydrogen control system. If the ability to perform the hydrogen control function is maintained, continued operation is permitted with two hydrogen recombiners inoperable for up to 7 days.

Seven days is a reasonable time to allow two hydrogen recombiners to be inoperable because the hydrogen control function is maintained and because of the low probability of the occurrence of a LOCA that would generate hydrogen in amounts capable of exceeding the flammability limit.

The frequency recommended for this surveillance in the Improved Standard Technical Specifications (NUREG-1432, Rev. 1) is 18 months. The bases for NUREG 1432 was developed for permanently installed hydrogen recombiners. The two portable hydrogen recombiners at PVNGS are shared among the three units; therefore, the 6 month frequency from the initial licensing basis is retained for reliability considerations.

SR 3.6.7.3 Performance of a CHANNEL CALIBRATION to include a system functional test for each hydrogen recombiner ensures that the recombiners are operational and can attain and sustain the temperature necessary for hydrogen recombination. In particular, this SR requires 1) resistance checks of motors, thermocouples, and heater systems, 2) testing/calibration of all flow elements, switches, and temperature elements, and

Snubbers excluded from this inspection program are those installed on nonsafety-related systems and then only if their failure or failure of the system on which they are installed, would have no adverse effect on any safety-related system.

When one or more snubbers are unable to perform their associated safety function(s), either the supported system must be declared inoperable immediately or TS LCO 3.0.8 must be entered. TS LCO 3.0.8 may only be entered if the restrictions described in the LCO 3.0.8 TS Bases are met. TS LCO 3.0.8 is an allowance, not a requirement. When any snubber is unable to perform its associated safety function, the supported system may be declared inoperable instead of utilizing LCO 3.0.8.

Required Action A.2 must be completed whenever Condition A is entered. This Required Action emphasizes the need to perform the evaluation to determine if the components to which the nonfunctional snubbers are attached were adversely affected by the non-functionality of the snubbers in order to ensure that the component remains capable of meeting the designed service. Restoration alone per Required Action A.1.1 or A.1.2 is insufficient because higher than analyzed stresses may have occurred and may have affected the supported system.

A list of individual snubbers with detailed information of snubber location and size and of system affected shall be available at the plant in accordance with Section 50.71(c) of 10 CFR Part 50. The accessibility of each snubber shall be determined and approved by the Plant Review Board. The determination shall be based upon the existing radiation levels and the expected time to perform a visual inspection in each snubber location as well as other factors associated with accessibility during plant operations (e.g., temperature, atmosphere, location, etc.), and the recommendations of Regulatory Guides 8.8 and 8.10. The addition or deletion of any hydraulic or mechanical snubber shall be made in accordance with Section 50.59 of 10 CFR Part 50.

The acceptance criteria specified in the 2001 Edition, 2003 Addenda, of the ASME OM Code, Subsection ISTD are to be used in the visual inspection to determine the functionality of the snubbers.

The service life of a snubber is established via manufacturer input and information through consideration of the snubber service conditions and associated installation and maintenance records (newly installed snubber, seal replaced, spring replaced, in high radiation area, in high temperature area, etc.). The requirement to monitor the snubber service life is included in the 2001 Edition, 2003 Addenda, of the ASME OM Code, Subsection ISTD to ensure that the snubbers periodically undergo a performance evaluation in view of their age and operating conditions. These records will provide statistical bases for future consideration of snubber service life.

T3.7.102 Sealed Source Contamination The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is based on 10 CFR 70.39(c) limits for plutonium.

This limitation will ensure that leakage from byproduct, source, and special nuclear material sources will not exceed allowable intake values.

Sealed sources are classified into three groups according to their use, with surveillance requirements commensurate with the probability of damage to a source in that group. Those sources which are frequently handled are required to be tested more often than those which are not. Sealed sources which are continuously enclosed within a shielded mechanism (i.e. sealed sources within radiation monitoring or boron measuring devices) are considered to be stored and need not be tested unless they are removed from the shield mechanism.

TRM Specification Bases TRM 6.0.100 TRM SPECIFICATION BASES provide for heat removal. Failure to meet the LCO by having only a single OPERABLE ADV on one or both SGs would result in the loss of the single failure ADV backup on one or both SGs. An ADV is considered OPERABLE when it is capable of providing a controlled relief of the main steam flow, and is capable of fully opening and closing on demand, by remote operation.

This TLCO supplements Technical Specification (TS)

LCO 3.7.4, which requires one ADV line per SG to be OPERABLE, until TS LCO 3.7.4 can be revised.

Actions The ACTIONS table is modified by a Note indicating that separate Condition entry is allowed for each SG. This is acceptable since (1) the primary success path for accident mitigation would continue to be available by the remaining OPERABLE ADV on each SG when a single ADV is inoperable on each SG, and (2) the risk associated with continuing to operate the plant without the single failure ADV backup on both SGs for up to 7 days is much lower than the risk associated with shutting down the plant.

A.1 If the requirements of TSR 3.7.200 are not met, the condition must be documented in the corrective action program and an operability determination must be initiated as necessary to determine the impact on equipment in the TSs. This action is required to assure compliance with the TSs.

B.1 If one of the two required ADV lines on a SG is inoperable, Required Action B is to restore the ADV line to OPERABLE status within 7 days. The 7 day Completion Time is acceptable because (1) when one ADV on either or both SGs is inoperable, the single failure backup is no longer available, but the primary success path for accident mitigation continues to be available by the remaining OPERABLE ADVs; (2) the heat removal function of the ADVs can also be provided by the steam bypass control valves to the condensers and atmosphere when offsite power (continued)

The limitations on the fuel building essential ventilation system ensure that all radioactive material released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere. The OPERABILITY of this system and the resulting iodine removal capacity are consistent with the assumptions of the safety analyses.

If one FBEVS train is inoperable, action must be taken to immediately verify that the OPERABLE FBEVS is capable of being powered from an emergency power source and to restore the inoperable train to OPERABLE status within 7 days.

During this time period, the remaining OPERABLE train is adequate to perform the FBEVS function. The 7 day Completion Time is reasonable, based on the risk from an event occurring requiring the inoperable FBEVS train, and ability of the remaining FBEVS train to provide the required protection.

During movement of irradiated fuel assemblies in the fuel building, if the Required Actions of Condition A cannot be completed within the required Completion Time, the operation (i.e., fan running, valves/dampers aligned to the post-FBEVAS mode, etc.) or movement of irradiated fuel assemblies must be suspended immediately. The first action ensures that the remaining train is OPERABLE, that no undetected failures preventing system operation will occur, and that any active failure will be readily detected. If the system is not placed in the emergency mode of operation, this action requires suspension of the movement of irradiated fuel assemblies in order to minimize the risk of release of radioactivity that might require the actuation of FBEVS. This does not preclude the movement of fuel to a safe position.

Movement of spent fuel casks containing irradiated fuel assemblies is not within the scope of the Applicability of this technical specification. The movement of dry casks containing irradiated fuel assemblies will be done with a single-failure-proof handling system and with transport equipment that would prevent any credible accident that could result in a release of radioactivity.

TRM Specification Bases TRM 6.0.100 TRM SPECIFICATION BASES Fire detectors that are used to actuate fire suppression systems represent a more critically important component of a plant's fire protection program than detectors that are installed solely for early fire warning and notification.

Consequently, the minimum number of OPERABLE fire detectors must be greater.

The loss of detection capability for fire suppression systems, actuated by fire detectors, represents a significant degradation of fire protection for any area. As a result, the establishment of a fire watch patrol must be initiated at an earlier stage than would be warranted for the loss of detectors that provide only early fire warning. The establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is restored to OPERABILITY.

When inoperable fire detection instrument(s) are inside containment, REQUIRED ACTIONs B.2 and C.2 require either (1) a fire watch patrol inspect the containment zone(s) with the inoperable instrument(s) at least once per 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , or (2) monitor the containment air temperature at least once per hour at each of the 7 locations listed in the Bases for Technical Specification SR 3.6.5.1. The plant computer with the control room installed multi-point recorder and annunciator is an acceptable means of monitoring temperatures inside containment when required. The continuous monitoring of containment air temperature by the plant computer and multi-point recorder exceeds the requirement of hourly monitoring. The plant computer and multi-point recorder utilizes pre-set alarm points for each monitored location. If setpoints are exceeded, an audio annunciation is received that alerts the operator of an abnormal condition.

The fire suppression system consists of the water system, spray and/or sprinklers, CO2, Halon, fire hose stations, and yard fire hydrants and associated emergency response vehicles. The collective capability of the fire suppression systems is adequate to minimize potential damage to safety related equipment and is a major element in the facility fire protection program.

The surveillance requirements provide assurance that the minimum OPERABILITY requirements of the suppression systems are met. An allowance is made for ensuring a sufficient volume of C02/Halon in the CO2/Halon storage tank by verifying either the weight or the level of the tank.

TRM Appendix TA PTLR TA1.0 Reactor Coolant System Pressure and Temperature Limits Report (PTLR)

This Pressure and Temperature Limits Report (PTLR) has been prepared in accordance with the requirements of Technical Specification (TS) 5.6.9. The following TSs are addressed in this report:

TS 3.4.3, RCS Pressure and Temperature Limits; TS 3.4.6, RCS Loops - Mode 4; TS 3.4.7, RCS Loops - Mode 5, Loops Filled; TS 3.4.11, Pressurizer Safety Valves - Mode 4; and TS 3.4.13, Low Temperature Overpressure Protection System.

TA2.0 Operating Limits Parametric limits for the above LCOs were developed using NRC-approved methods specified in Technical Specification 5.6.9 (Ref. 1). Application of the methodology approved for developing P/T limits, i.e., report CE NPSD-683-A (Ref. 2), to the Palo Verde Nuclear Generating Station is detailed in WCAP-16835 (Ref. 3).

The initial PTLR was submitted to the NRC along with the Technical Specification (TS) amendment request to relocate P/T limits to the PTLR (Ref. 4). The NRC approved the relocation of the P/T limits from TS to the PTLR in amendment no. 178 (Ref. 5). Subsequent changes to the PTLR are controlled in accordance with TS 5.6.9b and 10 CFR 50.59, and the PTLR shall be provided to the NRC upon issuance for each reactor vessel fluence period and for any revision or supplement thereto as required by TS 5.6.9c.

The pressure-temperature limit curves comply with Appendix G to 10 CFR Part 50 requirements that the temperature of the closure head flange and vessel flange regions must be at least 120°F higher than the limiting RTNDT for these regions. This RTNDT limit applies during normal operation, including heatup and cooldown, when the core is not critical and the vessel pressure exceeds 625 psia, (20% of the pre-service hydrostatic test pressure of 3125 psia).

Refer to the Technical Specifications for LCOs and surveillance requirements applicable to RCS pressure and temperature limits. Specific TS LCO limits relocated from the Technical Specifications into this PTLR are given below.

TRM Appendix TA PTLR TA3.0 Neutron Fluence The design value of peak fast neutron fluence through 32 EFPY for determining the limiting reactor vessel beltline material adjusted reference temperature is 3.29E+19 n/cm2 (E > 1.0 MeV) and corresponds to the fluence at the vessel clad-to-base metal interface. For conservatism, this peak fluence is assumed to apply to each of the PVNGS reactor vessel beltline plates and welds; i.e.,

no reduction factor is applied to account for axial or azimuthal variations from the peak value.

A summary of fast neutron fluence and fluence factors through 32 EFPY determined at the 1/4T and 3/4T locations in the vessel wall is given in Table TA3-1. These fluence values are used to calculate the adjusted reference temperature at PVNGS Units 1, 2 and 3.

The surveillance capsule withdrawal schedules are presented in UFSAR Tables 5.3-13 through 5.3-19A and summarized in WCAP-16835 (Ref. 3). Test results and analyses of withdrawn surveillance specimens were reported in References 6, 7, and 8.

Seven reactor vessel surveillance capsules have been removed from PVNGS Units 1, 2 and 3 through December 2007, with a minimum of two credible data sets available for each PVNGS unit. Even though WCAP-16835 shows that the post-irradiation surveillance capsule test results for PVNGS units are credible, the calculation of ART takes no credit for those credible results.

TA6.0 Application of Reactor Vessel Surveillance Data TA6.1 Applicability to Adjusted Reference Temperature Data from the reactor vessel surveillance program or from other supplemental sources were not used to determine the adjusted reference temperature (ART) values for the PVNGS beltline materials described in Section 5. The surveillance program data from each of the three Palo Verde units were evaluated for credibility; chemistry factors were also derived for those surveillance materials. (This assessment is further detailed in Report WCAP-16835 [Ref. 3].)

Chemistry factors determined following Position 1.1 of Regulatory Guide 1.99 are shown to be conservative relative to those derived from surveillance plate and weld measurements for each of the PVNGS units. Therefore, no credit is taken for those credible results in the calculation of ART.

(continued)

Palo Verde Units 1, 2, 3 TA-9 Rev 52 07/16/10

TRM Appendix TA PTLR Each new set of surveillance results, as new data becomes available, will be evaluated to ascertain that the Position 1.1 chemistry factors remain conservative relative to the surveillance results. This will ensure that the existing RCS P/T limits remain conservative for continued plant operation or will be revised as needed to provide conservative RCS pressure-temperature limits.

TA6.2 Evaluation of Surveillance Data Credibility Regulatory Guide 1.99 describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of low-alloy steels used in the PVNGS reactor vessels when credible surveillance capsule data is available. Position C.2 of Regulatory Guide 1.99 describes the method for calculating the adjusted reference temperature and Charpy upper-shelf energy of reactor vessel beltline materials using surveillance capsule data.

The methods of Position C.2 apply when two or more credible surveillance data sets become available from each unit.

Post-irradiation surveillance capsule test results for PVNGS were evaluated with respect to the credibility criteria of Regulatory Guide 1.99 Revision 2.

Results of the credibility assessment found that:

The surveillance program plates and welds are those judged to be most likely controlling with regard to radiation-induced embrittlement, Charpy data scatter does not cause ambiguity in the determination of the 30 ft-lb shift, Measured RTNDT shifts are consistent with the predicted shifts, Capsule irradiation temperature matches that of the vessel wall, and Correlation monitor data falls within the scatter band for that material and therefore meets the credibility test.

Revision 2 of Regulatory Guide 1.99 defines five requirements that must be met for surveillance data to be judged credible. The purpose of the following discussion is to apply these credibility requirements to PVNGS to show that the reactor vessel surveillance data are credible.

Criterion 1: Materials in the capsules should be those judged most likely to be controlling with regard to radiation embrittlement.

Palo Verde Units 1, 2, 3 TA-10 Rev 52 07/16/10

TRM Appendix TA PTLR The beltline region of the reactor vessel is defined in Appendix G(II)(F) to 10 CFR Part 50, Fracture Toughness Requirements, as:

Beltline or beltline region of the reactor vessel means the region of the reactor vessel (shell material including welds, heat affected zones, and plates or forgings) that directly surrounds the effective height of the active core and adjacent regions of the reactor vessel that are predicted to experience sufficient neutron radiation damage to be considered in the selection of the most limiting material with regard to radiation damage.

Table TA6-1 identifies the Units 1, 2, and 3 reactor vessel base metal beltline plate materials selected for the PVNGS surveillance program.

Table TA6-1 Base Metal Materials Selected for Surveillance Program PVNGS Plate ID Number Plate Location (1)

Unit 1 M-4311-1 Lower Shell Unit 1(1) M-6701-2 Intermediate Shell Unit 2 F-773-1 Lower Shell Unit 3 F-6411-2 Lower Shell (1)

Unit 1 has two different base metal surveillance materials.

The weld materials for the PVNGS Units 1, 2, and 3 surveillance programs are selected to duplicate the materials in the lower shell axial weld seams. Test specimens from these materials are heat-treated to a condition representative of the final metallurgical condition of the weld metal in the completed reactor vessel. These surveillance weld metals were made with the same weld wire heat as that of the vessel beltline weld seams and are, therefore, representative of all beltline weld seams.

Intermediate shell plate M-6701-2 in Unit 1 has the highest initial RTNDT and the highest ART of all PVNGS plate materials in the beltline region.

Therefore, the PVNGS Units 1, 2, and 3 surveillance material meets the intent of this criterion.

Criterion 2: Scatter in the plots of Charpy energy versus temperature for the irradiated and unirradiated conditions should be small enough to permit the determination of the 30 ft-lb temperature and upper shelf energy unambiguously.

(continued)

Palo Verde Units 1, 2, 3 TA-11 Rev 52 07/16/10

TRM Appendix TA PTLR Evaluation of Charpy energy versus temperature for the unirradiated and irradiated condition is presented in References 6, 7, and 8. Based on engineering judgment, the scatter in the data presented is small enough to permit the unambiguous determination of the 30 ft-lb temperature and the upper shelf energy of the PVNGS Units 1, 2, and 3 surveillance materials. Thus, the PVNGS surveillance program meets this criterion.

Criterion 3: When there are two or more sets of surveillance data from one reactor, the scatter of RTNDT values about a best-fit line drawn as described in Regulatory Position 2.1 normally should be less than 28°F for welds and 17°F for base metal. Even if the fluence range is large (two or more orders of magnitude), the scatter should not exceed twice those values. Even if the data fail this criterion for use in shift calculations, they may be credible for determining decrease in upper shelf energy if the upper shelf can be clearly determined, following the definition given in ASTM E 185-82.

The surveillance program for PVNGS Units 1, 2, and 3 is based on ASTM E185-79, which presents criteria for monitoring changes in the fracture toughness properties of reactor vessel beltline materials. References 6, 7, and 8 describe the post-irradiation evaluations of PVNGS surveillance materials.

The credibility results shown in Tables TA6-2, TA6-3 and TA6-4 for Units 1, 2, and 3, respectively, present the shift measurements available to date. Those values are compared to predictions based on a chemistry factor determined following Position 1.1 of Regulatory Guide 1.99. In all cases, the difference between the measured and predicted shift is less than 17ºF for the surveillance plates and less than 28ºF for the surveillance welds. Therefore, this criterion is met for the PVNGS Units 1, 2, and 3 surveillance program plate and weld materials.

TRM Appendix TA PTLR Criterion 4: The irradiation temperature of the Charpy specimens in the capsule should match the vessel wall temperature at the cladding/base metal interface within +/- 25°F.

All reactor vessel surveillance specimen capsule holders are attached to the inside vessel wall cladding in the beltline region at PVNGS. This capsule holder attachment method meets the design and inspection requirements of the ASME Code, Sections III and XI. The location of the specimens relative to the reactor vessel beltline provides assurance that the reactor vessel wall and the specimens experience equivalent operating conditions such that the temperatures will not differ by more than 25°F. Hence this criterion is met.

Criterion 5: The surveillance data for the correlation monitor material in the capsule should fall within the scatter band of the data base for that material.

As shown in Tables TA6-2, TA6-3, and TA6-4, the correlation monitor materials from PVNGS Units 1, 2, and 3 meet the credibility test to be within the scatter band of the database for that material.

TA6.3 Derivation of Chemistry Factors from Surveillance Data The derived chemistry factor (CF) values for each of the Palo Verde Units 1, 2, and 3 surveillance materials is provided in Tables TA6-2, TA6-3, and TA6-4.

The derived chemistry factor for the Unit 1 surveillance plate (M-6701-2) and surveillance weld (Heat 90071) are 27.5ºF and 4.9ºF, respectively. These chemistry factor values compare favorably with their respective values of 37ºF and 27.8ºF determined following Position 1.1 of Regulatory Guide 1.99.

Similar conservative results are found for Unit 2 plate (F-773-1) and surveillance weld (Heat 3P7317), and for Unit 3 plate (F-6411-2) and surveillance weld (Heat 4P7869). Therefore, chemistry factors determined following Position 1.1 of Regulatory Guide 1.99 are shown to be conservative relative to those derived from surveillance plate and weld measurements for each of the PVNGS units.
