Introduction:
The TRM is established as part of implementing an NRC approved Safety Evaluation Report. The TRM provides a central location for those items that have been relocated out of Technical Specifications, as well as any other items deemed appropriate by plant management, and may be physically located and maintained in the back of the existing Technical Specifications or in a separate binder on distinctly colored paper. The TRM may contain TRM Limiting Conditions for Operation (TLCOs), lists, cross-references, acceptance criteria, programs or operational conveniences.
The controls established by this procedure provide permanent records to document required reviews, implementation and NRC submittal of TRM changes, as applicable.
The definitions contained in Technical Specifications Section 1.0,"Definitions," apply to the TRM. All items relocated from the plant Technical Specifications to the TRM shall retain their existing numbering with a "TRM" added in the front. For example, Surveillance Requirement (SR) 4.13 in the plant Technical Specifications becomes TRM 4.13 upon relocation to the TRM. In addition, the TRM control requirements have been incorporated into the FSAR as FSAR Section 13.10, "Technical Requirements Manual." As such, changes to the TRM are governed by the l0CFR50.59 change process.The TLCOs are contained in Section 3.0 and include operational requirements, TRM Surveillance Requirements (TSRs), and Required Actions for inoperable equipment.
References to "Specifications" within the TRM refer to the Technical Specifications unless otherwise noted.While the TLCOs are to be treated like Technical Specifications from an implementation viewpoint, the TLCOs are essentially procedures.
Therefore, unless specifically stated in the TLCO, entry into or violation of a TRM Required Action, or violation of a TRM Surveillance Requirement is not specifically reportable per 10 CFR 50.72 or 10 CFR 50.73.Likewise, power reductions and/or plant shutdowns required to comply with TRM ACTIONS are not specifically reportable per 10 CFR 50.72(b)(1)(i)(A) or 10 CFR 50.73(a) (2)(i) (A) or (a) (2) (i) (B). Failure to comply with TLCO requirements shall be treated as a failure to follow procedure and entered into the corrective action program, as appropriate.
TRM 1.0 DEFINITIONS AA. Vital Fire Suppression Water System -The vital fire suppression water system is that part of the fire suppression system which protects those instruments, components,'
and systems required to perform a safe shutdown of the reactor. The vital fire suppression system includes the water supply, pumps, and distribution piping with associated sectionalizing valves, which provide immediate coverage of the Reactor Building, Control Room Building, and Diesel Generator Rooms.JJ. Process Control Program (PCP) -A process control program shall contain the sampling, analysis, tests, and determinations by which wet radioactive waste from liquid systems is assured to be converted to a form suitable for off-site disposal.VY TRM Revision 22 1.0-1 VYNPS TRM TRM 3.0 LIMITING CONDITIONS FOR TRM 4.0 SURVEILLANCE REQUIREMENT (SR)OPERATION APPLICABILITY APPLICABILITY TRM 3.0.1 RESERVED TRM 4.0.1 SRs shall be met during the modes or other specified conditions in the Applicability for individual TLCOs, unless otherwise stated in the SR.Failure to meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the TLCO. Failure to perform a Surveillance within the specified frequency shall be failure to meet the TLCO except as provided in TRM 4.0.3.Surveillances do not have to be performed on inoperable equipment or variables outside specified limits.TRM 4.0.2 Unless otherwise stated in these specifications, periodic surveillance tests, checks, calibrations, and examinations shall be performed within the specified surveillance intervals.
These intervals may be adjusted plus 25%. The operating cycle interval is considered to be 18 months and the tolerance stated above is applicable.
TRM 4.0.3 If it is discovered that a surveillance was not performed within its specified frequency, declaring applicable TRM Limiting Conditions for Operation (TLCOs)not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified frequency, whichever is greater.

Functional tests and calibrations are not required when systems are not required to be operable.VY TRM Revision 21 3.2-16 VYNPS TRM TRM BASES: TRM 3.2 PROTECTIVE INSTRUMENTATION The trip logic for the nuclear instrumentation control rod block logic is 1 out of n; i.e., any trip on one of the six APRMs, six IRMs or four SRMs will result in a rod block. The minimum instrument channel requirements for the IRMs may be reduced by one for a short period of time to allow for maintenance, testing or calibration.
The purpose of the APRM rod block function is to avoid conditions that would require Reactor Protection System action if allowed to proceed. The APRM upscale rod block alarm setting is selected to initiate a rod block before the APRM high neutron flux scram setting is reached. The APRM upscale rod block trip setpoint is varied as a function of reactor recirculation flow. This provides an effective rod block if core average power is increased above the power level specified at any flow rate.The APRM -Upscale (Flow Bias) control rod block Trip Function is not credited in the safety analysis.
The Trip Setting specified in Table TRM 3.2.5 for the APRM -Upscale (Flow Bias) Trip Function is a nominal value (Table TRM 3.2.5 Footnote (5)) and not an operability limit. A "nominal" trip setting is an approximate value within a defined calibration tolerance.
Because the instrumentation does not provide a safety function, uncertainty relationships associated with analytical limits do not exist. Nominal trip setpoints have corresponding administrative limits (as-found and as-left tolerances) which can render the field setting above or below the nominal value. These administrative limits are typically based on equipment performance and are required by calibration procedures/data sheets. The nominal value Trip Setting is selected to ensure a control rod block is initiated before the reactor protection system APRM High Flux (Flow Bias) trip setpoint is reached.As with the reactor protection system APRM High Flux (Flow Bias) Trip Setting, the APRM -Upscale (Flow Bias) control rod block Trip Setting is reduced for single recirculation loop operation to account for the difference between the single loop and two loop drive flow at the same core flow. The terms for the Trip Setting of the APRM -Upscale (Flow Bias) Trip Function are defined as follows: S = Nominal setpoint in percent of rated thermal power (1,912 MWt).W = percent of rated two loop drive flow where 100% rated drive flow is that flow equivalent to 48 x 106 lbs/hr core flow.Since the purpose of the APRM -Upscale (Flow Bias) Trip Function is to avoid conditions that would require reactor protection system action if allowed to proceed, the APRM -Upscale control rod block Trip Function is required to be operable during reactor power operation.
VY TRM Revision 24 3.2-17 VYNPS TRM TRM BASES: TRM 3.2 PROTECTIVE INSTRUMENTATION (Continued)
For single recirculation loop operation, the APRM rod block trip setting is reduced in accordance with the analysis presented in NEDO-30060, I February 1983. This adjustment accounts for the difference between the single loop and two-loop drive flow at the same core flow. The single loop equations are based on a bounding (maximum) difference of 8%between two loop and single loop drive flow at the same core flow.The IRM rod block function provides local as well as gross core protection.
The scaling arrangement, is such that trip setting is less than a factor of 10 above the indicated level. Analysis of the worst-case accident results in rod block action before MCPR approaches the fuel cladding integrity safety limit.A downscale indication on an APRM or IRM is an indication the instrument has failed or the instrument is not sensitive enough. In either case, the instrument will not respond to changes in control rod motion and thus control rod motion is prevented.
Post-Accident Instrumentation TRM Specification 3.2.G requires that the post-accident monitoring (PAM)instrumentation of Table TRM 3.2.6 be operable during reactor power operation.
PAM instrumentation is not required to be operable during shutdown and refueling conditions when the likelihood of an event that would require PAM instrumentation is extremely low. The primary purpose of the PAM instrumentation is to display plant variables that provide information required by the control room operators during accident situations.
The operability of the PAM instrumentation ensures that there is sufficient information available on selected plant parameters to monitor and assess plant status and behavior following an accident.If Table TRM 3.2.6 minimum number of operable instruments for safety valve position from acoustic monitors is not met, a note provides alternate indication to assist the operator in determining safety valve position.
One of these alternate indications is drywell pressure.
If the alternate instrumentation is not available, the loss of drywell pressure indication will place the plant in a restrictive Technical Speciification LCO. Thus, no instruction is provided for follow-up actions if both the primary and backup instrumentation is not available, as plant operation will be restricted by the Technical Specifications.

Coolant Chemistry Materials in the primary system are primarily 304 stainless steel and Zircaloy.
The reactor water chemistry limits are established to prevent damage to these materials.
The limit placed on chloride concentration is to prevent stress corrosion cracking of the stainless steel.When conductivity is in its proper normal range (approximately 10 !Imho/cm during reactor startup and 5 ýimho/cm during power operation), pH and chloride and other impurities affecting conductivity must also be within their normal range. When and if conductivity becomes abnormal, then chloride measurements are made to determine whether or not they are also out of their normal operating values. This would not necessarily be the case. Conductivity could be high due to the presence of a neutral salt, e.g., Na2SO4, which would not have an effect on pH or chloride.
In such a case, high conductivity alone is not a cause for shutdown.
In some types of water-cooled reactors, conductivities are in fact high due to purposeful addition of additives.
In the case of BWRs, however, no additives are used and where neutral pH is maintained, conductivity provides a very good measure of the quality of the reactor water.Significant changes therein provide the operator with a warning mechanism so he can investigate and remedy the condition causing the change before limiting conditions, with respect to variables affecting the boundaries of the reactor coolant, are exceeded.
Methods available to the operator for correcting the off-standard condition include operation of the reactor cleanup system reducing the input of impurities and placing the reactor in the cold shutdown condition.
The major benefit of cold shutdown is to reduce the temperature dependent corrosion rates and provide time for the cleanup system to reestablish the purity of the reactor coolant. During startup periods, which are in the category of less than 100,000 pounds per hour, conductivity may exceed 5 pmho/cm because of the initial evolution of gases and the initial addition of dissolved metals.During this period of time when the conductivity exceeds 5 ýtmho (other than short term spikes), samples will be taken to assure the chloride concentration is less than 0.1 ppm.The NobleChem application process increases the conductivity of the reactor water due to the ionic characteristics of the injected compounds of platinum and rhodium. During the application process, the major species that contribute to increased conductivity are sodium, nitrate/nitrite and hydroxide.
These reaction by-products are expected to cause reactor coolant conductivity to approach 10umho/cm.
Studies and observations have indicated that the relatively low temperature, the limited time frame of application and the non-aggressive ionic species resulting from noble metal injection have little threat of any enhanced crack initiation in the resulting high conductivity environment.
VY TRM Revision 14 3.6-3 VYNPS TRM TRM BASES: TRM 3.6 and 4.6 Reactor Coolant System B. Coolant Chemistry (Continued)
The conductivity of the reactor coolant is continuously monitored.
The samples of the coolant which are taken every 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> will serve as a reference for calibration of these monitors and is considered adequate to assure accurate readings of the monitors.
If conductivity is within its normal range, chlorides and other impurities will also be within their normal ranges. The reactor coolant samples will also be used to determine the chlorides.
Therefore, the sampling frequency is considered adequate to detect long-term changes in the chloride ion content.The conductivity of the feedwater is continuously monitored and alarm set points, consistent with Regulatory requirements given in Regulatory Guide 1.56, "Maintenance of Water Purity in Boiling Water Reactors," have been determined.
The results from the conductivity monitors on the feedwater can be correlated with the results from the conductivity monitors on the reactor coolant water to indicate demineralizer breakthrough and subsequent conductivity levels in the reactor vessel water.VY TRM Revision 14 3.6-4 VYNPS TRM TRM 3.7 TRM LIMITING CONDITIONS FOR OPERATION TRM 4.7 TRM SURVEILLANCE REQUIREMENTS TRM 3.7 STATION CONTAINMENT SYSTEMS Applicability:

Diesel-driven Fire Pump System VY TRM Revision 14 3.13-11 VYNPS TRM TRM BASES: TRM 3.13 & TRM 4.13 FIRE PROTECTION SYSTEMS On May 11, 1976, Vermont Yankee received a letter from the NRC requesting that an in-depth evaluation of the existing fire protection systems be performed using Branch Technical Position (BTP) APCSB 9.5-1 as a guide.Concurrent with this evaluation a fire hazards analysis of the entire plant complex was required.
In an effort to clarify the BTP an Appendix A was subsequently issued to specifically address operating plants.Enclosed with this Appendix the NRC requested that proposed Technical Specifications on fire protection also be submitted.
The subject section TRM 3.13/4.13 and the following specific bases are those specifications evolving from these efforts.A. The smoke, heat and flame detectors provide the early warning fire detection capability necessary to detect problems in vital areas of the plant. Surveillance requirements assure these sensors and their associated instruments to be operable.
When the equipment protected by the detectors is not required to be operable, specifications covering the sensors and instruments do not apply.B,C, The Vital Fire Suppression Water System, CO 2 systems, sprinkler D,F, systems and foam systems specifications are provided to meet and pre-established levels of system operability in the event of a G fire. These systems provide the necessary protection to assure safe reactor shutdown.
Periodic surveillance testing provides assurance that vital fire suppression systems are operable.The east and west switchgear rooms low pressure CO 2 storage tank TRM Specification minimum level of 50% provides for sufficient CO 2 quantity to achieve and maintain design concentration, in accordance with NFPA 12 (1993), in the east or west switchgear rooms. The TRM Specification minimum tank pressure of 270 psig will provide the minimum pressure to meet system design.E. Vital fire barrier penetration fire seals are provided to assure that the fire resistance rating of barriers is not reduced by a penetration.
Surveillance inspections shall be performed to insure that the integrity of these seals is maintained.
The diesel fire pump has a design consumption rate of 18 gallons of fuel per hour; therefore, 150 gallons provides for greater than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of operation.
Additional fuel can be delivered in about one hour and additional fuel is on site. When the equipment protected by the fire protection systems is not required to be operable, the specifications governing the fire protection system do not apply.The fire protection testing frequencies have been adjusted to utilize performance based testing. The goal is to achieve an availability factor of 99.0%. Based on this goal, the test frequencies may be increased up to the limits indicated, if the testing data supports the goal of a 99.0% availability factor. The Fire Protection Engineer will review test data to ensure that a 99.0% availability factor is met or exceeded and to recommend additional testing when this goal is not achieved.VY TRM Revision 14 3.13-12 VYNPS TRM TRM 6.0 ADMINISTRATIVE CONTROLS Administrative controls are the wriftten rules, orders, instructions, procedures, policies, practices, and the designation of authorities and responsibilities by the management to obtain assurance of safety and quality of operation and maintenance of a nuclear power reactor.These controls shall be adhered to.TRM 6.1 ORGANIZATION D.
