1.0 USE AND APPLICATIONS 1.0.1 Introduction Based on the NRC's Final Policy Statement on Technical Specification improvements for nuclear power plants, and 10 CFR 50.36, certain requirements may be relocated from the Technical Specifications (TS) to other licensee controlled documents (SAR, ODCM, administrative procedures). The Technical Requirements Manual (TRM) has been developed in an effort to centralize the requirements relocated from the TS and to ensure the necessary administrative controls are applied to these requirements.

j The TRM is intended for use as an operator aid that provides a central location for relocated items in a TS format. The individual TRM specifications are called Technical Requirements (TRs) and may be written in the current or standard TS format. In addition to the TS numbering and format for relocated items, the TRM provides a reference to the TS when

{

appropriate to assist the user in connecting the relocated information to the applicable TS.

l Some of the information in the TRM may also be duplicated in other ANO documents, such as, j

the SAR, ODCM, or Fire Protection Program.

1

}

1.0.2 TRM Format i

i The TRM format is sechoned and numbered similar to the TS. The TRs relocated from the TS l

will retain the same numbering as when they were in the TS, where possible. Maintaining the same numbering system will minimize unnecessary burden and reduce the probability of error produced by the relocation process. This system minimizes procedure changes necessary for the relocation and allows the TRM users a similar numbenng system that they are already j

familiar with. However, this format produces a TRM without a sequenced numbering system

!A for the TRs and the associated sections. An example of this condition would be in the j

instrumentation section where TR 3.3.3.3 is found without a preceding TR 3.3.3.2. Another j

example would be that the TRM contains a 1.0 sechon without a 2.0 section. The page l'

numbering in the TRM is sequential. An example of this would be the first page in the 3.3 section (TR 3.3.3.3) is 3.3-1. The index can be reviewed if there are any questions regarding l

the TR numbering and their associated page numbers.

1.0.3 Regulatory Status And Requirements The requirements in the TRM are considered as part of the licensing basis (a part of the SAR) and are to be treated as such. Failure to comply with a TR should be evaluated in accordance with the ANO corrective action program. These deviations from the TRM will be reviewed for operability and reportability in accordance with the applicable administrative procedures and regulatory requirements.

These controls are necessary because the purpose of relocating the ruquirements from TS is i

not to reduce the level of control on these items. The purpose of relocating the requirements is to provide the flexibility for their modification without requiring a TS change.

l 1.0 USE AND APPLICATIONS (continued) 1.0.4 Changes To The TRM O

Design modifications, procedure changes, license amendments, etc. have the potential to affect the TRM. If this occurs, the initiating department should follow the administrative controls prescribed in procedure 1000.150, " Licensing Document Maintenance" for submitting changes to the TRM. To ensure that the information in the TRM remains current, the TRM Responsibility Matrix has been developed and is included in procedure 1000.150. This matrix identifies the lead organization responsible for each of the TRs including their bases. TRM changes are subject to the requirements of 10 CFR 50.59 due to the TRM being considered a part of the SAR and therefore a licensing basis document. Changes to the TRM will be issued on a replacement page basis to controlled document holders following approval of the change in accordance with site procedures on document control.

1.0.5 NRC Reporting Of TRM Revisions Like the SAR, changes to the TRM are controlled under 10 CFR 50.59 and therefore do not require prior NRC approval unless the change involves a change to the TS or an unreviewed safety question. The most recent revision of the TRM will be sent to the NRC as part of the periodic SAR update process.

1.0.6 TS Applicability To The TRM The TRM may reference a TS LCO or Surveillance Requirement (SR) that applies to the relocated infonnation. All TRM references to the TS will be proceded by "TS or Technical O

Specification" and then the associated specification number. The 3.0 and 4.0 sections of the TS and their associated bases are applicable to the TRM. Any exemptions to the associated TS section 3.0 and 4.0 requirements will be listed in the associated TR. The defined terms in TS section 1.0 are also applicable to the TRM.

3.5.1.13 The Seismic Monitoring instrumentation shown in Table 3.5.1-1 shall be operable l

with a minimum measurement range of 0.01 - 1.0 g for Triaxial Time - History Accelerographs, 0.05 - 1.0 g for Triaxial Peak Accelerographs, and 2-25.4 Hz for Triaxial Rosponse Spectrum Recorders.

I l

BASES The operability of the chlorine detection system ensures that sufficient capability is available to j

promptly detect and initiate piut.ctive action in the event of an accidental chlorine release.

i This capability is required to protect control room personnel and is consistent with the recommendations of Regulatory Guide 1.95, " Protection of Nuclear Power Plant Control Room Operators against an Accidental Chlorine Release," February 1975.

i 1

The operability of the Seismic Monitoring instrumentation ensuies that sufficient capability is j

available to promptly determine the magnitude of a seismic event and evaluate the response j

of those features important to safety. This capability is required to permit comparison, of the i

measured roi.ponse to that used in the design basis for the facility to determine if plant shutdown is required pursuant to Appendix "A" of 10 CFR Part 100. The instrumentation is

{

consistent with the recommendations of Safety Guide 12, " Instrumentation for Earthquake,"

j published March 19,1971, and NUREG 0800 Section 3.7.4, " Seismic Instrumentation."

1.0 USE AND APPLICATIONS 1.0.1 Introduction O

Based on the NRC's Final Policy Statement on Technical Specification Improvements for nuclear power plants, and 10 CFR 50.38, certain requirements may be relocated from the Technical Specifications (TS) to other licensee controlled documents (SAR, ODCM, administrative procedures). The Technical Requirements Manual (TRM) has been developed in an effort to centralize the requirements relocated from the TS and to ensure the necessary administrative controls are applied to these requirements.

The TRM is intended for use as an operator aid that provides a central location for relocated items in a TS format. The individual TRM specifications are called Technical Requirements (TRs) and may be written in the current or standard TS format. In addition to the TS numbering and format for relocated items, the TRM provides a reference to the TS when appropriate to assist the userin connecting the relocated information to the applicable TS.

Some of the information in the TRM may also be duplicated in other ANO documents, such as, the SAR, ODCM, or Fire Protection Program.

1.0.2 TRM Format The TRM format is sectioned and numbered similar to the TS. The TRs relocated from the TS will retain the same numbering as when they were in the TS, where possible. Maintaining the same numbering system will minimize unnecessary burden and reduce the probability of error produced by the relocation process. This system minimizes procedure changes necessary for the relocation and allows the TRM users a similar numbering system that they are already familiar with. However, this format produces a TRM without a sequenced numbering system O

for the TRs and the associated sections. An example of this condition would be in the instrumentation section where TR 3.3.3.3 is found without a preceding TR 3.3.3.2. Another example would be that the TRM contains a 1.0 section without a 2.0 section. The page numbering in the TRM is sequential. An example of this would be the first page in the 3.3 section (TR 3.3.3.3) is 3.3-1. The index can be reviewed if there are any questions regarding the TR numbering and their associated page numbers.

1.0.3 Regulatory Status And Requirements The requirements in the TRM are considered as part of the licensing basis (a part of the SAR) and are to be treated as such. Failure to comply with a TR should be evaluated in accordance with the ANO corrective action program. These deviations from the TRM will be reviewed for operability and reportability in accordance with the applicable administrative procedures and regulatory requirements.

These controls are necessary because the purpose of relocating the requirements from TS is not to reduce the level of cor*ol on these items. The purpose of relocating the requirements is to provide the flexibility for their modification without requiring a TS change.

1.0 USE AND APPUCATIONS (continued) 1.0.4 Changes To The TRM Design modifications, procedure changes, license amendments, etc. havs the potential to affect the TRM. If this occurs, the initiating department should follow the administrative l

controls prescribed in procedure 1000.150, "Ucensing Document Maintenance" for submitting changes to the TRM. To ensure that the information in the TRM remains current, the TRM Responsibility Matrix has been developed and is included in procedure 1000.150. This matrix identifies the lead organization responsible for each of the TRs including their bases. TRM changes are subject to the requirements of 10 CFR 50.59 due to the TRM being considered a part of the SAR and therefore a licensing basis document. Changes to the TRM will be issued on a replacement page basis to controlled document holders followmg approval of the change in accordance with site procedures on document control.

1.0.5 NRC Reporting Of TRM Revisions Uke the SAR, changes to the TRM are controlled under 10 CFR 50.59 and therefore do not require prior NRC approval unless the change involves a change to the TS or an unreviewed safety question. The most recent revision of the TRM will be sent to the NRC as part of the periodic SAR update process.

1.0.6 TS Applicability To The TRM The TRM may reference a TS LCO or Surveillance Requirement (SR) that applies to the relocated information. All TRM references to the TS will be preceded by "TS or Technical Speafication" and then the associated specification number. The 3.0 and 4.0 sections of the O

TS and their associated bases are applicable to the TRM. Any exemptions to the associated TS section 3.0 and 4.0 requirements will be listed in the associated TR. The defined terms in TS section 1.0 are also applicable to the TRM.

3.3 INSTRUMENTATION TR BASES 3/4.3.3.3 SEISMIC INSTRUMENTATION The OPERABluTY of the seismic instrumentation ensures that sufficient capability is available to promptly determine the magnitude of a seismic event and evaluate the response of those features important to safety. This capability is required to permit comparison of the measured response to that used in the design basis for the facility to determine if plant shutdown is required pursuant to Appendix "A" of 10 CFR Part 100. The instrumentation is consistent with the recommendations of Safety Guide 12, " Instrumentation for Earthquakes," March,1971.

3/4.3.3.4 METEOROLOGICAL INSTRUMENTATPON The OPERABILITY of the meteorologicalinstrumentation ensures that sufficient meteorological data is available for estimating potential radiation doses to the public as a result of routine or accidental release of radioactive materials in the atmosphere. This capability is required to evaluate the need for initiating pietstive measures to protect the health and safety of the public and is consistent with the recommendations of Regulatory Guide 1.23 "Onsite Meteorological Programs," February 1972.

3/4.3.3.7 CHLORINE DETECTION SYSTEMS The OPERABILITY of the chlorine detection system ensures that sufficient capability is available to promptly detect and initiate protective action in the event of an accidental chlorine release. This capability is required to protect control room personnel and is consistent with the recommendations of Regulatory Guide 1.95, " Protection of Nuclear Power Plant Control Room Operators Against an Accidental Chlorine Release," February 1975.

3/4.3.4.1 TURBINE OVERSPEED PROTECTION This requirement is provided to ensure that the turbine overspeed protection instrumentation and the turbine speed control valves are OPERABLE and will protect the turbine from excessive overspeed. Protection from turbine excessive overspeed is required since excessive overspeed of the turbine could generate potentialty damaging missiles which could impact and damage safety related components, equipment or structures.
