FNP-FSAR-16 16.0 TECHNICAL SPECIFICATIONS TABLE OF CONTENTS 16-i REV 29 4/20 16.1 INSTRUMENTATION............................................................................................. 16.1-1 16.1.1 SEISMIC INSTRUMENTATION........................................................... 16.1-1 16.1.2 METEOROLOGICAL INSTRUMENTATION........................................ 16.1-1 16.1.3 CONTAINMENT HYDROGEN MONITORS......................................... 16.1-1 16.2 TECHNICAL REQUIREMENTS MANUAL............................................................. 16.2-1 16.3 RISK MANAGED TECHNICAL SPECIFICATIONS............................................... 16.3-1 16.3.1 PRA FUNCTIONALITY........................................................................ 16.3-1 16.3.2 PRA TECHNICAL ADEQUACY........................................................... 16.3-1

FNP-FSAR-16 16.1-1 REV 25 4/14 16.1 INSTRUMENTATION 16.1.1 SEISMIC INSTRUMENTATION The seismic instrumentation requirements are addressed in TR 13.3.6 in the Technical Requirements Manual.

16.1.2 METEOROLOGICAL INSTRUMENTATION The meteorological instrumentation requirements are addressed in TR 13.3.7 in the Technical Requirements Manual.

16.1.3 CONTAINMENT HYDROGEN MONITORS The Containment Hydrogen Monitor requirements are addressed in TR 13.3.8 in the Technical Requirements Manual.

FNP-FSAR-16 16.2-1 REV 21 5/08 16.2 TECHNICAL REQUIREMENTS MANUAL The conversion of the FNP Technical Specifications, based on NUREG-0452, to the FNP Technical Specifications, based on NUREG-1431, Revision 1 resulted in the creation of the Technical Requirements Manual (TRM) which includes certain technical requirements which do not meet the 10 CFR 50.36 criteria for inclusion in the Technical Specifications. Technical requirements that are licensing commitments, but which may be controlled by the licensee in accordance with the process for changes, tests, and experiments as provided in 10 CFR 50.59, can be maintained in the TRM.

The TRM contains selected requirements that apply to the operation of FNP with the intent being to provide a single, prominent, and easily accessible document for operating staff to reference and which will support the operating staff's compliance with these requirements with a minimum of effort. These requirements are conditions for operation, associated action requirements, and surveillance requirements with the format for presentation of the requirements being the same as used in the FNP NUREG-1431 based Technical Specifications.

The administrative controls for the TRM are the same as used for the control of the FSAR.

These administrative controls ensure proposed TRM changes do not require NRC approval pursuant to 10 CFR 50.59, or if a change does require NRC approval, the controls ensure NRC approval prior to implementation of the change.

FNP-FSAR-16 16.3-1 REV 29 4/20 16.3 RISK MANAGED TECHNICAL SPECIFICATIONS The Risk Managed Technical Specifications (RMTS) will allow the calculation of risk informed completion times (RICT) for certain LCO Conditions. Those are identified in the Completion Time column of the particular LCO Condition, with the phrase, "...or in accordance with the Risk Informed Completion Time Program". Without this phrase in the LCO Condition Completion Time column, the particular Condition is not in the program and a RICT cannot be calculated.

The program is consistent with the guidelines of NEI 06-09, Rev. 0, "Risk Informed Technical Specifications Initiative 4b, Risk Managed Technical Specifications (RMTS) Guidelines".

16.3.1 PRA FUNCTIONALITY The RICT calculation performed depends on the configuration of the plant at the time of the inoperability of the component. Additionally, the inoperable component may be declared "PRA Functional" if the component's inoperability does not affect the PRA success criteria. For example, if an ECCS pump becomes inoperable, its PRA Functionality status would depend on the ability of the pump to meet the PRA flow rate success criteria. This is per the guidelines of NEI 06-09, section 11, which lists further requirements and restrictions on declaring a component PRA Functional.

PRA Functionality for a case of all trains and equipment required by the Technical Specifications inoperable has additional restrictions identified in Section 5.5.20 of the Technical Specifications.

16.3.2 PRA TECHNICAL ADEQUACY The on-record PRA model that forms the basis for the FNP Configuration Risk Management (CRM) Tool has been developed to the requirements of Reg. Guide 1.200, "An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for RiskInformed Activities" and is subjected to peer reviews per the requirements of NRC endorsed applicable PRA standards and SNC procedures. These peer reviews are formally documented along with the findings and observations of the review, and their corresponding resolutions.
