1.0 DESCRIPTION

The proposed license amendment request (LAR) would reflect the installation of the General Electric-Hitachi (GEH) digital Nuclear Measurement Analysis and Control (NUMAC) Power Range Neutron Monitoring (PRNM) system. The following Technical Specifications (TS) sections are affected by this change:

TS 2.2 Limiting Safety System Settings TS 3/4.1.4.3 Rod Block Monitor TS 3/4.3.1 Reactor Protection System Instrumentation TS 3/4.3.6 Control Rod Block Instrumentation TS 3/4.3.11 Oscillation Power Range Monitor TS 3/4.4.1 Recirculation System TS 6.9.1.9 Core Operating Limits Report TS 6.9.3 Special Reports The planned upgrade will replace the existing analog Average Power Range Monitor (APRM)

subsystem of the Neutron Monitoring System with the more reliable, digital NUMAC PRNM System during the Spring 2018 refueling outage. This modification will simplify management and maintenance of the system and also includes the following elements:

1. The PRNM System design includes an Oscillation Power Range Monitor (OPRM) capability; to detect and suppress reactor instability. The OPRM function continues to

satisfy the same regulatory requirements as the currently installed OPRM equipment.

The existing ABB OPRM with BWROG Option III stability solution will change to the GEH OPRM with the Detect and Suppress Solution - Confirmation Density (DSS-CD) stability solution.

2. Full Average power range monitor, Rod block monitor, Technical Specification improvement program (ARTS) implementat ion. Currently, HCGS has implemented 'partial' ARTS. The PRNM system will allow the change to power biased (vs flow biased) Rod Block Monitor (RBM) setpoints. This change allows for Rod Withdrawal Error (RWE) analyses performed for each future reload to take credit for rod blocks during the rod withdrawal transients.
3. Technical Specifications Task Force (TSTF) 493, Revision 4, "Clarify Application of Setpoint Methodology for LSSS Functions". The changes to the TSs include the adoption of the TSTF-493 Option A surveillance notes for the affected PRNM functions.

The NRC has issued Interim Staff Guidance (ISG) in digital instrumentation and control (I&C)

DI&C-ISG-06 that describes the licensing process that may be used in the review of LARs associated with digital I&C system modifications. The LAR format and contents of Section 4.0 (Technical Evaluation) of this Attachment 1 are consistent with the guidance provided in Enclosure E and Section C.3 of DI&C-ISG-06. As needed, additional sections have been added to address other aspects of this submittal.

LAR H15-01 LR-N15-0178 3 of 47 A similar PRNM system was approved for installation at Columbia Generating Station (CGS) 1 , and serves as a precedent for the HCGS installation.

The proposed changes are supported by the following:

NRC-approved GEH Licensing Topical Report (LTR) NEDC-32410P-A, Nuclear Measurement Analysis and Control Power Range Neutron Monitor (NUMAC PRNM) Retrofit Plus Option III Stability Trip Function, Volumes 1 and 2, including Supplement 1 (References 1a, 1b, 1c), referred to collectively as the NUMAC PRNM LTR. The NUMAC PRNM LTR provides the primary technical basis for the proposed changes.

NRC-approved GEH Licensing Topical Report (LTR) NEDC-33075P-A; Revision 8, GE Hitachi Boiling Water Reactor Detect and Suppress Solution - Confirmation Density (Reference 2).

Hope Creek Generating Station NUMAC PRNM Upgrade, Enclosures 2 (NEDO-33684, Non-Proprietary) and 3 (NEDC-33684P, Proprietary) of this submittal. These enclosures provide documentation that includes:

o ISG-06 Enclosure B required documentation to support the HCGS PRNM installation.

o HCGS plant-specific responses required (utility action required) by the NUMAC PRNM LTR. Note, that since HCGS is also implementing the OPRM DSS-CD solution, the plant-specific responses also reference DSS-CD.

o Deviations from the NUMAC PRNM LTR and CGS Approval (per ISG-06 Section D.8.2 and ISG-06 Enclosure B Item 1.16).

o Evaluation supporting transition from partial ARTS to full ARTS.

o DSS-CD HCGS Evaluation.

The complete list of the Enclosure documents (Appendices A through T) is provided in Enclosure 2 and 3; a Roadmap is provided cross-referencing the documents to ISG-06 Enclosure B (Enclosure 1). The Enclosure 2 and 3 appendices are correspondingly referenced in Section 4.0 (Technical Analysis) of this Attachment 1.

"lnoperative" trip is retained but is revised to reflect the new NUMAC PRNM system equipment and delete the minimum number of LPRM detector count from this trip.

Change is consistent with Sections 3.2.10 and 8.3.1.2 of Reference 1a. LAR H15-01 LR-N15-0178 6 of 47 No. Change Justification 6 Page 2-4, Table 2.2.1-1, Reactor Protection System Instrumentation Setpoints, Function 2.e. Added Function 2.e, 2-Out-Of-4 Voter.

Function for 2-Out-Of-4 Voter added consistent with Sections 8.3.1.2 and 8.3.1.4 of Reference 1a.

There is no Trip Setpoint or Allowable Value associated with this function. This function has been added because all 4 voter channels are required to be operable for this new addition to the logic. Each of the four APRM channels provides signals to the 2-out-of-4 voters for APRM and OPRM trips. 7 Page 2-4, Table 2.2.1-1, Reactor Protection System Instrumentation Setpoints, Function 2.f Added Function 2.f, OPRM Upscale.

Function for OPRM Upscale added consistent with Reference 1c (Section 8.4.1.4).

This function is relocated from current Limiting Condition of Operation (LCO) 3.3.11 which is being deleted. The Trip Setpoint will be provided in the COLR; there is no Allowable Value associated with this function. 8 Page 2-4, Table 2.2.1-1, Reactor Protection System Instrumentation Setpoints, Notations Changes Added new note (a) stating: "When the Automated BSP Scram Region Setpoints are implemented in accordance with Action 10 of Table 3.3.1-1, the Simulated Thermal Power-Upscale Flow Biased Setpoint will be adjusted per the CORE OPERATING LIMITS REPORT."

"-and less than 90% of RATED THERMAL POWER with MCPR less than the value specified in the CORE OPERATING LIMITS REPORT, or THERMAL POWER greater than or equal to 90% of RATED THERMAL POWER with MCPR less than the value specified in the CORE OPERATING LIMITS REPORT" Consistent with implementation of Full ARTS as described in Enclosure 3 of this submittal; Appendix S, Supplemental Information for the Average Power Range Monitor, Rod Block Monitor and Technical Specification Improvement (ARTS) Program for Hope Creek Nuclear Generating Station, Section 3.5. LAR H15-01 LR-N15-0178 7 of 47 No. Change Justification 9 Page 3/4 3-1, TS 3/4 3.1 Reactor Protection System Instrumentation, Surveillance Requirement (SR) 4.3.1.2, Logic System Functional Test Add: "Functional Unit 2.a, 2.b, 2.c, 2.d, and 2.f do not require separate LOGIC SYSTEM FUNCTIONAL TESTS. The LOGIC SYSTEM FUNCTIONAL TEST for APRM Function 2.e includes simulating APRM and OPRM trip conditions at the APRM channel inputs to the voter channel to check all combinations of two tripped inputs to the 2-Out-Of-4 voter logic in the voter channels."

Logic System Functional Test added for the 2-Out-Of-4 voter only consistent with Section 8.3.5.2 of Reference 1a and page H-31 of Reference 1c.

The only portion of the PRNM system that is not directly confirmed by other tests is the voting logic through and including the voter output relays. Therefore, the logic system functional test for APRM Functions 2.a, 2.b, 2.c, and 2.d will be deleted. Similarly, the proposed APRM Function 2.f, "OPRM Upsc ale," does not require an LSFT SR.

The Logic System Functional Test will remain at a frequency of 18 months. 9a Page 3/4 3-1, TS 3/4 3.1 Reactor Protection System Instrumentation

Correct typographical error in TS Title; delete extra "4".

Format change only, correcting typographical error inadvertently introduced via Amendment 187. 10 Page 3/4 3-1, TS 3/4 3.1 Reactor Protection System Instrumentation, Surveillance Requirement (SR) 4.3.1.3, Reactor Protection System Response Time Added requirement for licensee controlled SFCP: "RESPONSE TIME Testing for Function 2.e has a frequency of 18 months and for Function 2.e, "n" equals 8 channels for the purpose of determining the staggered test frequency. Testing of APRM and OPRM outputs shall alternate."

Addition consistent with Sections 8.3.4.4 and 8.4.4.4 of References 1a and 1c.

The LPRM detectors, APRM channels, OPRM channels, and 2-Out-of-4 Voter channels digital electronics are exempt from response time testing. The requirement for response time testing of the RPS logic and RPS contactors will be retained by including a response time testing requirement for the new APRM Function 2.e, "2-Out-of-4 Voter." The Response Time Testing will remain at a frequency of 18 months. Specific details about the staggered test basis will be reflected in the Licensee controlled SFCP. LAR H15-01 LR-N15-0178 8 of 47 No. Change Justification 11 Page 3/4 3-1, TS 3/4 3.1 Reactor Protection System Instrumentation, Limiting Condition for Operation, Action a Add the following new *** notation to Action a:

"For Functional Unit 2.a, 2.b, 2.c, 2.d, and 2.f, inoperable channels shall be placed in the tripped condition to comply with Action a.

Placing a trip system in trip is not applicable since these Functions provide trip inputs to both trip systems."

This change in text is consistent with Reference 1b and 1c. Consistent with Section 8.3.2.2 Reference 1a, each APRM channel provides input, or is shared by each RPS trip system. 12 Page 3/4 3-1, TS 3/4 3.1 Reactor Protection System Instrumentation, Limiting Condition for Operation, Action b.

Add to the ** notation: "N ote, Action b. is not applicable for Functional Unit 2.a, 2.b, 2.c, 2.d, and 2.f."

3.0 BACKGROUND

The proposed change would reflect the installation of the General Electric-Hitachi (GEH) digital Nuclear Measurement Analysis and Contro l (NUMAC) Power Range Neutron Monitoring (PRNM) system. The PRNM system enables HCGS to implement full ARTS and also incorporates the OPRM function (with HCGS changing to the DSS-CD stability methodology).

The PRNM system replaces the existing APRM system which is part of the Neutron Monitoring System (NMS). The NMS monitors the neutron flux level in the reactor in three separate, overlapping ranges; all using in-core instrum entation systems (refer to Hope Creek Updated Final Safety Analysis Report (UFSAR) Figure 7.6-1). The system provides automatic core protection signals in the event of power transients. The NMS includes the Source Range Monitor (SRM) system, Intermediate Range Monitor (IRM) system, and the power range monitoring system. The power range monitoring is accomplished by the APRM system, which receives core flux level signals from the Local Power Range Monitors (LPRM). Additional information on the safety related elements of the NMS are provided in Section 7.6 of the Hope Creek UFSAR.

HCGS is a GE BWR/4. The existing design incorporates six APRM channels. Each APRM channel uses input signals from a number of local power range monitors (LPRMs). The six APRM channels are combined in two groups of three channels each to form two trip channels.

The PRNM modification will replace the six-channel APRM with a four-channel APRM configuration whereby each channel uses one-fourth of the total LPRM detectors. The APRM functions in each channel are the same; however four 2-Out-of-4 Voter logic channels are added. Each APRM provides inputs to all four of the 2-Out-of-4 Voter logic channels. Outputs from two voter logic channels supply inputs to each of two Reactor Protection System (RPS) trip system divisions.

The changes are based on LTRs for PRNM and DSS-CD:

The PRNM LTR was reviewed and approved by the NRC staff in 1995 and 1997 (References 1a, b, c). The overall change is further supported by prior operating experience that has been gained from changes to install similar General Electric- Hitachi (GEH) Nuclear Measurement Analysis and Control (NUMAC)-based equipment in U.S. nuclear power plants. The LTRs and their corresponding safety evaluations (SEs) establish utility-specific licensee actions that each referencing license amendment request (LAR) must perform, as applicable. The LTRs provide a series of block diagrams to show a variety of GEH NUMAC PRNMS equipment configurations that could be applied to different General Electric (GE) Boiling-Water Reactor (BWR) designs

using GEH NUMAC hardware and software.

The DSS-CD LTR was reviewed and approved by the NRC staff in 2013 (Reference 2). The LTR defines the licensing basis and reload applications for the "Detect and Suppress Solution - Confirmation Density" (DSS-CD) methodology. DSS-CD is a type of long-term stability solution that has features similar to the previously approved Option III. DSS-CD maintains for defense-in-depth the algorithms that were approved for Option III:

the Period Based Detection Algorithm (PBDA), the Amplitude Based Algorithm (ABA), and the Growth Rate Algorithm (GRA).

LAR H15-01 LR-N15-0178 25 of 47 The GEH NUMAC PRNM development approach includes reliance upon pre-developed hardware and software components. A high-level description of these previously developed components is contained in the LTR (References 1a, b, c). The set of pre-developed software supports interfaces with NUMAC modules and instrument-specific application functions, which are configured to construct plant-specific instrumentation such as the HCGS PRNM system.

Most of this previously developed software was produced to satisfy the applicable regulatory evaluation criteria that the NRC staff used to evaluate the base LTR in 1995. However, since that time, the applicable regulatory evaluation criteria used by the NRC staff to evaluate software-based safety functions within digital safety-related equipment have changed. The evaluations provided with this submittal reflect the current regulatory criteria.

Also included in this submittal is an evaluation of the HCGS PRNM system against the plant specific action items (utility action required items) defined in the PRNM LTR and Safety Evaluation (SE). The implementation of DSS-CD is also reflected in the plant-specific

evaluation.

To prepare for the PRNM upgrade and to support the required licensing process, PSEG has performed, or is in process of performing, the following activities:

1. Critical Digital Review

A Critical Digital Review (CDR) 4 , of the GE-Hitachi (GEH) NUMAC PRNM System was performed prior to finalizing the approval of the PRNM Upgrade Project. The purpose and scope of a CDR was to determine if a given digital-based product is both capable and suitable for use in a given nuclear application - based upon a predefined set of critical characteristics such as physical characteristics (e.g., size, connector type), performance characteristics (e.g., timing, functions, failure detection), and dependability (i.e., programmatic) characteristics.

The CDR utilized a systematic risk-informed appr oach to evaluate a digital product's ability to perform specific functions, and the ability to respond to abnormal conditions and events when operating within the plant. The goal of the review was not only to evaluate the NUMAC PRNM product, but to gain a sufficient understanding of Hope Creek specific design considerations, areas of potential risk, and activities to ensure they were addressed in subsequent planning.

The CDR concluded that:

The GEH NUMAC PRNM product is a technically suitable replacement for the existing Safety-Related Hope Creek PRNM. GEH has an established regulatory approved Appendix B quality program The GEH quality program and related processes are suitable to ensure the quality of the design, configuration control, Part 21 reportability, and maintenance throughout the life of the NUMAC PRNM system The GEH NUMAC PRNM utilizes a basic set of modules and components, but each system is uniquely designed to meet plant-specific needs and constraints.

4 Also referred to as an independent System Integrity Review (SIR) LAR H15-01 LR-N15-0178 26 of 47 2. CGS Benchmarking and Incorporation of Industry Lessons-learned

The CGS PRNM upgrade/amendment is cited as a precedent for the HCGS PRNM upgrade. Close alignment with the CGS project was established during the initial stages of the HCGS project, and has been maintained, including CGS site visits, sharing of information, benchmarking, and lessons learned. Other industry operating experience (OE) has also been incorporated into the HCGS PRNM project.

3. Procedure Development Plan PRNM procedures from several other utilities, including CGS, have been obtained as a reference for developing the HCGS PRNM procedures. Draft procedures will be in place prior to the FAT scheduled for the first quarter of 2016. In addition, HCGS is using Nine Mile Point PRNM Manual (GEH supplied system manual) as a reference since the Nine Mile Point PRNM system is similar to HCGS.
4. GEH Setpoint Methodology Audit As part of the PRNM upgrade, GEH is performing the setpoint calculations for the new NUMAC PRNM system. These calculations are proprietary, and a calculation results report is delivered to PSEG as part of the project in lieu of the full setpoint calculations.

For past PRNM projects the NRC typically performs an audit of the GEH calculations.

PSEG audited the GEH setpoint program prior to preparation of the setpoint calculations. Topics covered included the GEH setpoint methodology and the GEH TSTF-493 methodology. The audit concluded that the GEH Instrument Setpoint Methodology - Overview document delivered fo r the Phase 1 licensing submittal met the required NRC guidance.

5. TS Amendment removing APRM OPCON 5 operability requirement A HCGS license amendment was approved in 2013 that changed Technical Specification (TS) 3/4.3.1, "Reactor Protection System Instrumentation," and TS 3/4.3.6, "Control Rod Block Instrumentation" by modifying the operability requirements for the average power range monitoring (APRM) instrumentation system. The amendment eliminated the requirements that the APRM "Upscale" and "Inoperative" scram and control rod withdrawal block functions be operable in the "Refueling" Operational Condition (OPCON) 5. This change will permit a more efficient installation of the PRNM system upgrade during the refueling outage.

The PRNM design includes an automatic instability trip function, OPRM, which will be implemented with the GEH Boiling Water Reactor Detect and Suppress Solution - Confirmation Density (DSS-CD) methodology (Reference 2). HCGS will be transitioning to the DSS-CD solution from the current ABB OPRM with BWROG Option III stability solution.

The existing power range monitor functions are retained, including LPRM detector signal processing, LPRM averaging, APRM trips, and RBM logic and interlocks. The existing analog LPRM signal processing electronics, LPRM averaging and APRM trip electronics, LPRM detector power supply hardware and recirculation flow signal processing electronics are being replaced by integrated digital NUMAC chassis based APRM electronics.

The existing six APRM channels will be replaced with four channels of NUMAC APRM, each channel utilizing one-fourth of the total available LPRM detectors. Four 2-Out-of-4 Voter channels are being added between the APRM channels and the existing RPS logic. Each Voter receives input from all four APRM channels and provides input to one Reactor Protection System (RPS) trip logic. This ensures that each input to RPS is a voted result of all four APRMs.

All interfaces with external systems are maintained electrically equivalent using interface sub-assemblies with exception of the interface to the plant computer and plant operator's panel.

Interface to the plant computer system is accomplished by the NUMAC Interface Computer (NIC) system and the interface to the operator panel is accomplished with Operator Display Assemblies (ODAs), which replace the existing meter displays.

The PRNM design includes an automatic instability trip function, OPRM. The existing ABB OPRM with BWROG Option III stability solution will change to the GEH OPRM with the Detect and Suppress Solution - Confirmation Density (DSS-CD) stability solution. DSS-CD is designed to detect power oscillations upon inception and initiate control rod insertion (scram) to terminate the oscillations prior to any significant amplitude growth. DSS-CD introduces an enhanced

detection algorithm that detects the inception of power oscillations and generates an earlier power suppression trip signal based on successive period confirmation recognition and an amplitude component. The existing Option III algorit hms are retained (with generic setpoints) to provide defense-in-depth protection for unanticipated reactor instability events.

The existing flow-biased RBM will be replaced by a power dependent RBM. The power dependent RBM will permit HCGS to implement "Full" ARTS versus the current "Partial" ARTS; allowing cycle specific RWE analyses to credit the blocking of rod withdrawals. LAR H15-01 LR-N15-0178 28 of 47 Each APRM channel consists of a Master APRM instrument, a Slave APRM instrument, and a 2-Out-of-4 Voter, which are safety related. The safety functions performed by each APRM channel involve the processing of sensor inputs to produce a set of trip votes that must then satisfy 2-Out-of-4 coincidence voting logic to cause the PRNM relay outputs to the RPS trip system to change state.. Both the Master and the Slave instruments receive inputs from the associated LPRM detectors. Flow transmitters in each of the recirculation loops provide the loop flow input to the associated APRM Master instruments in each channel. APRM communication with RBM, which is not safety-related, is conducted through Fiber Direct Data Interface (FDDl). The FDDl Module provides electrical and communication isolation of the signals while permitting the data to be transmitted.

Each Master APRM instrument provides interfaces to the LPRM detectors and recirculation loop (Loops A and B) flow transmitters, processes detector signals, performs algorithms to produce a set of trip votes, interfaces with all four 2-Out-of-4 Voters to provide its trip votes, receives bypass and self-test status information from its channel's 2-Out-of-4 Voter, and exchanges data with its channel's Slave APRM and one RBM through two separate FDDl links.

Each Slave APRM instrument provides interfaces to a set of LPRM detectors, processes the signal, and exchanges the data with its Master APRM and one channel of the RBM through two separate FDDI links.

The FDDl module in the Master APRM instrument communicates with one RBM channel whereas a separate FDDl module in the Slave APRM instrument communicates with the other RBM channel. Each RBM channel (RBM A and RBM B) receives input from either the Master APRM or the Slave APRM module of each APRM channel.

Each 2-Out-of-4 Voter receives trip votes from all four channels of APRM and provides outputs to its associated RPS trip system based on the voter logic. Each 2-Out-of-4 Voter also receives the bypass switch status and forwards their status to the other three 2-Out-of-4 Voters. Bypass processing is implemented to prohibit more than one channel in bypass.

The 2-Out-of-4 Voters associated with APRM channels A, C, B, and D are referred to as A1, A2, B1, and B2, respectively for the HCGS installation. Each voter has an input to its associated channel of the RPS trip system which are also typically referred to as trip system A (A1 and A2) and trip system B (B1 and B2) respectively.

The "NUMAC Power Range Neutron Monitoring (PRNM) System Architecture Description" shows the interfaces between safety-related and nonsafety-related portions of the PRNM system (Appendix A of Enclosure 2 and 3).

The existing system provides outputs to the Plant Process Computer (PPC) or CRIDS. These points are all presently hardwired individually to computer I/O cabinets. The new system provides a new computer interface by processing all signals serially from the APRM and RBM NUMAC instruments through two redundant NICs to CRIDS. The NIC also sends APRM and LPRM gain adjustment factors from the Core Monitoring System computer, via the RBM's and NIC's, to the APRMs. The NIC consists of computer hardware processors and software programs that perform specific tasks to interface between the NUMAC instruments and CRIDs.

All communication interfaces between the RBM, the NIC, and the PPC are non-safety related. LAR H15-01 LR-N15-0178 29 of 47 Cyber Security requirements for these interfaces are addressed in accordance with the NRC approved cyber security plan for HCGS

5.

The PRNM upgrade includes Operator Display Assemblies (ODAs), which are installed at the operator's panel and provide process parameter s, trip and alarm status from the APRM and RBM channels. There are two APRM ODAs and two RBM ODAs. The APRM master and RBM instruments send this information to the ODAs over a one way fiber optic connection. The APRM ODA serves as an interface between the operator and the remote APRM and RBM instruments. Each APRM ODA is capable of displaying data from two APRM instruments in the same division. Each RBM ODA is capable of displaying data from two RBMs.

A single fiber optic bypass switch assembly will be installed on panel 10C651 in the main control room to select an APRM channel for bypass. The bypass switch has mutually exclusive positions, thus assuring that only one APRM/OPRM channel is bypassed at a time. This approach is consistent with the proposed TS operability requirements for three out of four APRM channels; thereby ensuring that no single failure will preclude a scram on a valid signal.

The station power sources to the PRNM system are from two independent battery-backed inverters. These inverters are classified as non-Safety Related since loss of output power due to open, short, or ground causes the PRNM system to trip. Safety Related electrical protection assemblies monitor voltage and frequency of the supply and trip when voltage or frequency are outside of the allowable range.

The PRNM system provides scram contact outputs from the 2-out-of-4 Voter for the following functions: 1) Neutron Flux- Upscale (Setdown)

2) Simulated Thermal Power - Upscale 3) Neutron Flux- Upscale 4) Inoperative
5) OPRM Upscale 5 Approved by the NRC via License Amendment Nos. 189 & 192 (ADAMS ML111861560 and ML12335A221) LAR H15-01 LR-N15-0178 30 of 47 4.1.2 Detailed System Description The PRNM system is described in detail in "NUMAC Power Range Neutron Monitoring (PRNM) System Architecture Description" provided as Appendix A 6 of Enclosure 2 and 3). Additional discussion on the PRNM power supply and test capability is provided below.

The APRM and RBM NUMAC instruments are powered by Quad Low Voltage Power Supplies (QLVPS), which provide auctioneered DC power to the instruments. There are five QLVPS in the system, one for each APRM channel and one that powers both RBM channels. Each QLVPS receives input power from both 120VAC sources to the PRNM system. The 2-out-of-4 voters and RBM interface modules are powered directly from 120VAC and are divisionally separated between the two 120VAC sources.

Two high voltage power supplies are provided in each APRM instrument to supply 0 to 200Vdc for the LPRM detectors. One high voltage power supply provides normal power to the LPRM detectors while the second is available to perform detector IV curves or as a backup to the normal high voltage power supply.

The NUMAC instruments automatically execute continuous self-test while the instrument key lock switch is in the operate position. When the instrument key switch is placed in the INOP position the self-test is suspended and may be performed manually. The self-test performs memory and internal microprocessor checks, interrogates internal registers on the circuit modules and measures internal voltages. If a fault is detected it is traced to the module level and displayed. Users can interface with the instrument front panel display for more detailed diagnostic information. Loss of an essential function results in an instrument INOP condition and is alarmed and non-essential faults are alarmed. The NUMAC instruments also include additional manual testing features that are performed with key switch in the INOP position.

The Two-out-of-Four Voter modules include automatic self-testing and manual testing features.

The APRM master instrument monitors the testing features of the Two-out-of-Four Voter.

Each NUMAC APRM and RBM instrument has a means to perform calibration of the hardware.

The calibration process is for the most part automatic. Internal voltage and frequency standards are calibrated to National Institute of Standards and Technology traceable standards when in the INOP/Calibrate mode of operation. The following functions are calibrated; clock frequency, analog to digital and digital to analog converters, high voltage power supplies and isolation amplifiers. The calibration correction factors are stored in the instruments nonvolatile memory.

The components and interfaces of the HCGS PRNMS are shown in the diagram below; the shaded boxes represent the new PRNM system:

6 The System Architecture Description also includes the Communications evaluation discussed in ISG 06 Section D.7.2 LAR H15-01 LR-N15-0178 31 of 47 To support installation of the PRNM system at HCGS, additional assessments and requirements have been completed as described below.

4.1.2.1 PRNM LTR Plant Specific Responses The PRNM LTR (Reference 1) requires utility specific responses for each PRNM installation; these are provided in Appendix R of Enclosure 2 and 3. Appendix R provides a table of the LTR section numbers and Utility Action Required. As discussed previously, HCGS is also implementing the oscillation power range monitor (OPRM) stability trip function using the Detect and Suppress Solution-Confirmation Density (DSS-CD) solution. Thus, the plant-specific responses also include reference to the DSS-CD stability solution. 4.1.2.2 OPRM Transition to DSS-CD The PRNM system includes an Oscillation Power Range Monitor (OPRM) capability; to detect and suppress reactor instability. The OPRM function continues to satisfy the same regulatory requirements as the currently installed OPRM equipment. The existing ABB OPRM with BWROG Option III stability solution will change to the GEH OPRM with the Detect and Suppress Solution - Confirmation Density (DSS-CD) stability solution. Enclosure 2 and 3 Appendix T provides the evaluation and justification for implementing DSS-CD at HCGS. LAR H15-01 LR-N15-0178 32 of 47 4.1.2.3 Transition to Full ARTS With the PRNM installation HCGS is transitioning from partial ARTS to full ARTS as described in the Supplemental Information for the Average Power Range Monitor, Rod Block Monitor and Technical Specification Improvement (ARTS) Program for Hope Creek Nuclear Generating Station (Appendix S) of Enclosure 2 and 3

7. The ARTS methodology was implemented at the Hope Creek Generating Station (HCGS) in 2006 (Amendment 163, ADAMS ML060620500 and ML060620470). In that implementation the

hardware portion of ARTS was omitted to avoid the physical plant modifications that would have been required. This non-hardware configuration resulted in RWE analyses performed for each reload with no credit for blocking of rod withdrawals.

With the installation of PRNM, HCGS is transitioning from partial ARTS to full ARTS with the Control Rod Block setpoints changing from flow-biased to power-biased. The RWE event analyses performed for each future fuel cycle will take credit for RBM generated rod blocks during the rod withdrawal error event. The results of the RWE event analysis will be considered in establishing the cycle specific operating limits for the fuel. With the implementation of the fuel cycle specific RWE event analysis, the values the RBM setpoints will be contained in the COLR.

Establishing the fuel cycle specific RBM requirements in the COLR is consistent with Generic Letter 88-16. GL 88-16 permitted the relocation of fuel cycle specific parameter limits to the COLR. The updated TS reflect the deletion of the Table 3.3.6-2 Rod Block Monitor Functions 1.a.i Flow Biased and 1.a.ii High Flow Clamped; the addition of the Low Trip Setpoint (LTSP), Intermediate Trip Setpoint (ITSP), and High Trip Setpoint (HTSP); the addition of the Low Power Setpoint (LPSP), Intermediate Power Setpoint (IPSP), and High Power Setpoint (HPSP) ranges; and the modification of the Downscale Trip Setpoint (DTSP). As described in Section 2.0(a) and 3.2 of the Supplemental Information for ARTS (Enclosure 3 Appendix S), the full ARTS implementation removes the flow biased RBM setpoints and replaces them with power biased trips. As described in Enclosure 3 Appendix S, Section 3.3.1, paragraph 8, the trip setpoints (LTSP, ITSP, and HTSP) are dependent on the MCPR value provided in the reload analysis.

Due to cycle-by-cycle variation, the setpoint values are referenced in the COLR. The LPSP, IPSP, and HPSP are described in Table 5 and Section 3.3.1, paragraph 7, of Enclosure 3 Appendix S. Power setpoints do not change on a cycle-by-cycle basis. Therefore, these power setpoint ranges (provided in Appendix P of Enclosure 3) are referenced directly in the Technical Specifications.

Lastly, as described in Enclosure 3 Appendix S Table 5, footnote 2, the DTSP is not important for RWE analysis and may be moved to the COLR.

7 Prior to implementation of the PRNM system, HCGS plans to transition from GE-14 to GNF2 fuel (Fall 2016). The cycle specific reload evaluations or analyses described in Appendices S and T of Enclosure 3 will be performed for the cycle of PRNM implementation and subsequent cycles for the fuel related PRNM elements, full implementation of ARTS and implementation of the GEH OPRM with the DSS-CD stability solution. The cycle specific reload evaluations or analyses will confirm the requirements described in Enclosure 3 Appendices S and T will be met on a cycle specific basis. LAR H15-01 LR-N15-0178 33 of 47 4.1.2.4 Cyber Security Considerations HCGS established an NRC approved Cyber Security defensive strategy and program that is compliant with NEI 08-09 and has been approved by the NRC via License Amendment Nos.

189 & 192. The program is implemented via Plant procedure IT-AA-503. The defensive strategy establishes 4 security levels:

Level 4 - Control & Safety System Network - Plant control systems Level 3 - Data Acquisition Network - Plant computer system network and associated components for collecting plant data Level 2 - Site Local Area Network Level 1 - Corporate Wide Area Network Cyber security boundary devices are defined according to Example 1 in NEI 08-09:

Firewall and network intrusion detection system implements boundary between Level 4 and level 3 (allows bi-directional communication, but implements information flow controls in NEI 08-09, Appendix D, Section 1.4 and Appendix E, Section 6) Data diode implements deterministic boundary between Level 3 and Level 2 (only allows communication from Level 3 to Level 2) 4.1.2.5 Human Factors Evaluation The PRNM LTR Plant Specific Responses (Enclosure 2 and 3, Appendix R) Item 2.3.4 states:

For any changes to the plant operator's panel, document in the submittal the human factors review actions that were taken to confirm compatibility with existing plant commitments and procedures.

In addition, Section 5.0 of the SE for the LTR identifies six plant-specific actions that require confirmation; Action 6 requires confirmation that any changes to the plant operator's panel have received human factors reviews per plant-specific procedures.

Human Factors engineering is addressed as part of the PRNM design change package (DCP), including changes to the operator panel, as discussed below. The PRNM DCP modifies the 10C651 Operator Console arrangement to accommodate the NUMAC PRNM System ODAs and the change from 6 APRM channels to 4 APRM channels. These modifications include: 1. Removing APRM E/F channels from APRM channel status indicators and recorders 2. Removing Flow Unit Bypass switches

3. Removing RBM Status indicator lights
4. Relocating the Scram Discharge Piping Volume Piping Logic Test and Hi Level Scram Bypass controls. 5. Relocating the 4 remaining APRM Monitor Status lights 6. Relocating the IRM Monitor Status lights and the IRM Bypass switches
7. Installing 2 APRM ODAs and 2 RBM ODAs 8. Replacement of two existing with one new APRM Bypass switch LAR H15-01 LR-N15-0178 34 of 47 PSEG procedure NC.DE-TS.ZZ-1017 identifies design guidance for incorporating human factors engineering principles into design changes based on the guidance in NUREG-0700. The following design principles are applicable to the changes made by the PRNM DCP: Functional Grouping Highlight Component Grouping Control Display Integration Legend Pushbutton Guidelines Key-operated Controls Labeling Demarcation Detailed analysis of compliance with NUREG-0 700 will be documented with the completion of the detailed design. The Phase 2 submittal of this PRNM LAR (provided approximately one year after this Phase 1 submittal) will provide a description of the NUREG-0700 compliance. A discussion of the OE assessed to support the PRNM upgrade will also be provided.

4.1.2.6 TSTF-493 PSEG will implement TSTF-493 Option A for the LSSS functions affected by the PRNM upgrade. PSEG has reviewed the model application and safety evaluation (ADAMS ML100710442) and determined it is applicable to HCGS.

Using the guidance of Appendix A of TSTF-493, the two Option A notes specified in the TSTF are applied to the channel calibration of the following affected LSSS functions:

TS Table 4.3.1.1-1:

Function 2. Average Power Range Monitors

a. Neutron Flux- Upscale (Setdown)
b. Simulated Thermal Power- Upscale
c. Neutron Flux- Upscale

TS Table 4.3.6-1:

Function1. Rod Block Monitor a. Upscale

The addition of the two notes to the above functions is discussed in Section 2 of this , and is reflected in the Attachment 2 TS Markup.

The first note requires evaluation of channel performance for the condition where the as-found setting for the channel setpoint is outside its as-found tolerance, but conservative with respect to the AV. The channel evaluation verifies that channel performance continues to satisfy safety analysis assumptions and channel performance assumptions within the setpoint methodology.

The purpose of the assessment is to ensure confidence in channel performance prior to returning the channel to service.

The second note requires that the as-left setting for the channel be returned to within the as-left tolerance of the Nominal Trip Setpoint (NTSP). Where a setpoint more conservative than the LAR H15-01 LR-N15-0178 35 of 47 NTSP is used in the plant surveillance procedures, the as-left and as-found tolerances, as applicable, will be applied to the surveillance procedure setpoint. This ensures that sufficient margin is maintained to the Safety Limit (SL) and/or Analytical Limit (AL). If the as-left channel setting cannot be returned to within the as-left tolerance of the NTSP, then the channel shall be declared inoperable. This note also indicates that the methodologies used for calculating the as-found and as-left tolerances are specified in the TS Bases. 4.1.3 System Response Time Enclosure 2(3) Appendix N provides the Response Time Analysis Report for the NUMAC PRNM. HCGS has reviewed the report and determined that the analysis bounds the HCGS requirements for the four trips listed in Table 1 of Appendix N.

4.2 System

(Hardware and Software) Development for the HCGS PRNM System (Section D.2 and D.4 of DI&C-ISG-06)

The initial NUMAC PRNM development completed in the early to mid-1990s, and the acceptability of the system level approach, functionality to be provided, and software development processes, including V&V, was determined using the regulatory evaluation criteria applicable at that time. However, the applicable regulatory evaluation criteria changed since these earlier reviews and approvals, and these changes include criteria against which the PRNM development processes had not been previously evaluated.

The CGS PRNM upgrade was the first PRNM project to address the updated regulatory guidance (consistent with ISG-06). GEH has adjusted the NUMAC PRNM system and software development life-cycle to align with the current regulatory guidance. Enclosure 2(3) Appendices B through E and K describe the NUMAC PRNM system life cycle process for the HCGS upgrade. 4.2.1 Design Analysis Report: Methodology Modifications ISG-06 Section D.8.2 requires a design analysis report that identifies deviations to the life cycle methodology from a previous NRC approval. Enclosure 2(3) Appendix K describes the evolution of the NUMAC life cycle and maps the BTP 7-14 plans to the corresponding GEH NUMAC plans:

14:

  • Software Installation Plan
  • Software Maintenance Plan
  • Software Training Plan
  • Software Operations Plan These plans are not required to be submitted with the Phase 1 submittal; these are required for implementation of the digital system (Phase 3).

The four GEH plans listed in the table jointl y define a development program for the HCGS NUMAC digital PRNM system that is consistent with NRC requirements for a high quality development process for software used in safety systems of nuclear power plants. NUREG 0800, Standard Review Plan, Branch Technical Position (BTP) 7-14, Guidance on Software Reviews for Digital Computer-Based Instrumentation and Control Systems, provides acceptance criteria for process planning. 4.2.2 NUMAC System Engineering Development Plan The NUMAC Systems Engineering Development Plan (Enclosure 2(3) Appendix B) addresses process planning characteristics defined in BTP 7-14 Section B.3.1.2, Software Development Plan; BTP 7-14 Section B.3.1.4, Software Integration Plan; and BTP 7-14 Section B.3.1.11, Software Configuration Management Plan. 4.2.3 NUMAC System Quality Assurance Plan The NUMAC Systems Quality Assurance Plan (Enclosure 2(3) Appendix C) addresses process planning characteristics defined in BTP 7-14 Section B.3.1.3, Software Quality Assurance Plan. 4.2.4 NUMAC System Independent Verification & Validation Plan The NUMAC Systems Independent Verification and Validation Plan (Enclosure 2(3) Appendix D) addresses process planning characteristics defined in BTP 7-14 Section B.3.1.9, Software Safety Plan; BTP 7-14 Section B.3.1.10, Software Verification and Validation Plan; and BTP 7-14 Section B.3.1.12, Software Test Plan. 4.2.5 Hope Creek Generating Station NUMAC PRNM System Management Plan The HCGS NUMAC PRNM System Management Plan(Enclosure 2(3) Appendix E) addresses process planning characteristics defined in BTP 7-14 Section B.3.1.1, Software Management

4.3 Software

Architecture / Design Outputs (Section D.3 of DI&C-ISG-06) BTP 7-14, Section B.3.3.2 requires a description of the software used in the computer (or platform) and the application software, how the software functions, how the various software components are interrelated, and how the software utilizes the hardware. This information is typically contained in the (a) platform and application software architecture description, (b) the LAR H15-01 LR-N15-0178 37 of 47 platform and application software requirements specification, and (c) the platform and application software design specification.

The (a) software architecture description is provided in the System Architecture Description document (Enclosure 2(3) Appendix A) as discussed previously in Section 4.1. The following documents describe (b) the software requirements specification and (c) the software design specification. 4.3.1 System Requirements Specification & APRM Performance Specification The NUMAC PRNM System Requirements Specification (Enclosure 2(3) Appendix F) defines the system requirements for the design and manufacture of a NUMAC based PRNM System. The NUMAC PRNM System is designed to replace the existing APRM and RBM channels in a Neutron Monitoring System (NMS) of a Boiling Water Reactor (BWR) nuclear power plant. The NUMAC PRNM System also provides the OPRM channels required for the detection of reactor instability, the ARTS functions, and the implementation of the 2/4 Logic interface to the Reactor Protection System (RPS).

The NUMAC APRM DSS-CD Performance Specification (Enclosure 2(3) Appendix F) defines the performance characteristics and application limits for the HCGS NUMAC APRM application which includes the OPRM Detect and Suppress Solution -

Confirmation Density (DSS-CD) and automatic Backup Stability Protection (BSP) functions. 4.3.2 APRM Functional Controller System Design Specification APRM Functional Controller System Design Specification (Enclosure 2(3) Appendix G) comprises the high level design of the NUMAC APRM Functional Controller software. The purpose of this document is twofold: Define the Functional software design in sufficient detail such that software implementation can be undertaken without need for major design decisions. Provide a means for understanding how the NUMAC Functional Controller Software fulfills design input requirements. 4.4 Environmental Equipment Qualification (Section D.5 of DI&C-ISG-06) Documentation of equipment qualification, that confirms that the equipment qualification envelopes plant-specific requirements, is required in the plant-specific license amendment when referencing the previously approved LTR. The equipment qualification activities on the PRNM system comply with IEEE Standard 603 Clause 5.4 (Reference Enclosure 2(3) Appendix O), in accordance with the requirements of IEEE Standard 323 ("IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations," 1983) and the guidance of IEEE Standard 344 ("IEEE Recommended Practices for Seismic Qualification of Class 1E Equipment for Nuclear Power Generating Stations," 2004).

The Hope Creek NUMAC PRNM System Qualification Program (Enclosure 2(3) Appendix H) identifies the requirements to which the replacement PRNM system equipment will be qualified. The program provides guidance for the qualification of the replacement PRNM system and direction on whether the equipment is to be qualified by type-testing, by analysis, or by a combination of the two. The replacement PRNM system components are to be qualified based on operating in conditions considered mild-environments in which they are located. The equipment qualification includes temperature, humidity, pressure, radiation, seismic, and electromagnetic compatibility (EMC). LAR H15-01 LR-N15-0178 38 of 47 4.5 Defense-In-Depth & Diversity (Section D.6 of DI&C-ISG-06)

BTP 7-19 and DI&C-ISG-02 8 provide guidance to address diversity and defense-in-depth (D3). The D3 analyses must confirm that vulnerabilities to common-cause failures (CCFs) have been adequately addressed; to provide reasonable assurance that CCFs do not defeat either the protection provided by alternative means (i.e., an independent and diverse safety function) or an echelon of defense that provides defense-in-depth.

The Hope Creek NUMAC PRNM Diversity and Defense in Depth Analysis (Enclosure 2(3)

Appendix I) provides the HCGS D3 analysis demonstrating compliance with the BTP 7-19 criteria. 4.6 Communications (Section D.7 of DI&C-ISG-06) Since the prior review and approval of the NUMAC PRNM LTR further NRC staff guidance has been made available that provides evaluation criteria applicable to safety-to-non-safety interfaces of digital inter-channel communication. DI&C-ISG-04, "Task Working Group #4:

Highly-Integrated Control Rooms-Communications Issues (HICRc)," provides current guidance on addressing communication issues in three areas:

Interdivisional Communications Command Prioritization Multi-divisional Control and Display Stations Section 7 of the NUMAC PRNM System Architecture Description (Enclosure 2(3) Appendix A) provides the PRNM communication analysis satisfying the positions in DI&C-ISG-04. 4.7 System, Hardware, Software, and Methodology Modifications (Deviations from the Prior LTRs) (Section D.8 of DI&CISG-06) A Design Analysis Report is required that identifies deviations to the system, hardware, software, or design lifecycle methodology 9 from a previous NRC approval of a digital I&C system or approved topical report. Enclosure 2(3) Appendix J provides the HCGS Design Analysis Report that identifies the deviations to the system, hardware, and software from previous NRC approvals. The "Hope Creek NUMAC PRNM System, Hardware, Software, and Methodology Modifications" Design Analysis Report addresses three specific areas:

Hope Creek deviations from the approved NUMAC PRNM LTR (Reference 1) Hope Creek deviations from the approved GE Boiling Water Reactor DSS-CD LTR (Reference 2). There are no deviations. HCGS differences from the CGS NUMAC PRNM system that was reviewed and approved by the NRC (Reference 3). The proposed HCGS system is very similar to the CGS system which is cited as a precedent. Note that consistent with Reference 1.a Section 5.3.5.7 HCGS does have an RRCS output; CGS does not. 4.8 Compliance with IEEE Standard 603 (Section D.9 of DI&C-ISG-06) Enclosure 2(3) Appendices O, M, L and P discuss how the PRNM System meets the requirements of IEEE Standard 603-1991.

8 ISG-02 is superseded by BTP 7-19 Revision 6 9 Deviations to the design lifecycle methodology are provided in a separate report as discussed in Section 4.2.1 (Design Analysis Report: [Life Cycle] Methodology Modifications) LAR H15-01 LR-N15-0178 39 of 47 4.8.1 Report on Compliance with IEEE Standards (603-1991 and 7-4.3.2-2003) and Theory of Operations Description Enclosure 2(3) Appendix O. This report discusses how the NUMAC PRNM complies with applicable clauses in IEEE Standard 603-1991 and IEEE Standard 7-4.3.2-2003. The report

also provides a discussion on the PRNM Theory of Operations Description (ISG-06 Enclosure B Item 1.20).

5.0 REGULATORY ANALYSIS

The PRNM upgrade incorporates redundancy, independence, and diversity while providing simplified management and maintenance of the system. The effect of the PRNM upgrade on TS and accident analyses has been evaluated. Appropriate setpoints have been evaluated for the new system and the TS accordingly revised. The required Defense-in-Depth and Diversity (D3) report has been prepared confirming that vulnerabilities to common-cause failures (CCFs) have been adequately addressed. The hardware and software development for the PRNM upgrade process complies with the Institute of Electrical and Electronics Engineers (IEEE) Standard 603-1991 Clause 5.3 "Quality," and IEEE Standard 7-4.3.2-2003 Clause 5.3 "Quality," including the digital system development life cycle, in order to provide a high quality and well defined development process. The independent V&V effort for the upgrade utilizes a process and activities that comply with IEEE Standard 7-4.3.2-2003 Clause 5.3.3, "Validation and Verification" to ensure the upgrade meets required specified functional requirements and criteria. Finally, the Software configuration management used for the upgrade complies with IEEE Standard 7-4.3.2-2003 Clause 5.3.5, "Software Configuration Management," control the system and programming throughout its development and use.

Therefore, PSEG concludes the proposed PRNM upgrade complies with the 10 CFR 50 regulations and associated regulatory guidance. 5.1 Applicable Regulatory Requirements/Criteria The following regulations and guidance are applicable to the proposed installation of the GEH

The proposed license amendment request (LAR) would reflect the installation of the General Electric-Hitachi (GEH) digital Nuclear Measurement Analysis and Control (NUMAC) Power Range Neutron Monitoring (PRNM) system. The planned upgrade will replace the existing analog Average Power Range Monitor (APRM) sub-sy stem of the existing Neutron Monitoring System with the more reliable, digital NUMAC PRNM System. The system upgrade incorporates the Oscillation Power Range Monitor (OPRM) function and the transition from flow-biased to power biased Rod Block Monitor (RBM).

The following Technical Specifications (TS) sections are affected by this change:

  • TS 2.2 Limiting Safety System Settings
  • TS 3/4.1.4.3 Rod Block Monitor
  • TS 3/4.3.11 Oscillation Power Range Monitor
  • TS 3/4.4.1 Recirculation System

LAR H15-01 LR-N15-0178 45 of 47 PSEG has evaluated whether a significant hazards consideration is involved with the proposed amendment by focusing on the three conditions set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

The probability of accidents occurring is not affected by the PRNM system, as the PRNM system is not the initiator of any accident and does not interact with equipment whose failure could cause an accident. The transition from flow-biased to power-biased RBM does not increase the probability of an accident; the RBM is not involved in the initiation of any accident. The regulatory criteria established for the APRM, OPRM, and RBM systems will be maintained with the installation of the upgraded PRNM system. Therefore, the proposed change does not involve a significant increase in the probability of an accident previously evaluated.

The consequences of accidents are not affected by the PRNM system, as the setpoints in the PRNM system will be established so that all analytical limits are met. The unavailability of the new system will be equal to or less than the existing system and, as a result, the scram reliability will be equal to or better than the existing system. No new challenges to safety-related equipment will result from the PRNM system modification. The change to power biased RBM allows for Rod Withdrawal Error (RWE) analyses performed for each future reload to take credit for rod blocks during the rod withdrawal transients. The results of the RWE event analysis will be used in establishing the cycle specific operating limits for the fuel. The proposed change will also replace the currently installed and NRC approved Asea Brown Boveri (ABB) OPRM Option III long-term stability solution with an NRC approved General Electric-Hitachi (GEH) Detect and Suppress Solution - Confirmation Density (DSS-CD) stability solution (reviewed and approved by the NRC in Reference 2, Licensing Topical Report). The OPRM meets the GDC 10, "Reactor Design," and 12, "Suppression of Reactor Power Oscillations," requirements by automatically detecting and suppressing design basis thermal hydraulic oscillations to protect specified fuel design limits. Therefore, the proposed change does not involve a significant increase in the consequences of an accident previously evaluated.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No.

The components of the PRNM system will be supplied to equivalent or better design and qualification criteria than is currently required for the plant. Equipment that could be affected by PRNM system has been evaluated. No new operating mode, safety-related equipment lineup, accident scenario, or system interaction mode was identified. Therefore, the upgraded PRNM system will not adversely affect plant equipment.

LAR H15-01 LR-N15-0178 46 of 47 The new PRNM system uses digital equipment that has software controlled digital processing points and software controlled digital processing compared to the existing PRNM system that uses mostly analog and discrete component processing (excluding the existing OPRM). Specific failures of hardware and potential software common cause failures are different from the existing system. The effects of potential software common cause failure are mitigated by specific hardware design and system architecture as discussed in Section 6.0 of the NUMAC PRNM LTR, and supported by a plant specific evaluation. The transition from a flow-biased RBM to a power dependent RBM does not change its function to provide a control rod block when specified setpoints are reached. The change does not introduce a sequence of events or introduce a new failure mode that would create a new or different type of accident. Failure(s) of the system have the same overall effect as the present design. No new or different kind of accident is introduced. Therefore, the PRNM system will not adversely affect plant equipment.

The currently installed APRM System is replaced with a NUMAC PRNM system that performs the existing power range monitoring functions and adds an OPRM to react automatically to potential reactor thermal-hydraulic instabilities.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

3. Does the proposed amendment involve a significant reduction in a margin of safety?

Response: No.

The proposed TS changes associated with the NUMAC PRNM system implement the constraints of the NUMAC PRNM system design and related stability analyses. The NUMAC PRNM system change does not impact reactor operating parameters or the functional requirements of the PRNM system. The replacement equipment continues to provide information, enforce control rod blocks, and initiate reactor scrams under appropriate specified conditions. The power dependent RBM will continue to prevent rod withdrawal when the power-dependent RBM rod block setpoint is reached. The MCPR and

Linear Heat Generation Rate (LHGR) thermal limits will be developed on a cycle specific basis to ensure that fuel thermal mechanical design bases remain within the licensing limits during a control rod withdrawal error event and to ensure that the MCPR SL will not be violated as a result of a control rod withdrawal error event.

The proposed change does not reduce safety margins. The replacement PRNM equipment has improved channel trip accuracy compared to the current analog system, and meets or exceeds system requirements previously assumed in setpoint analysis. The power dependent RBM will support cycle specific RWE analysis ensuring fuel limits are not exceeded. Thus, the ability of the new equipment to enforce compliance with margins of safety equals or exceeds the ability of the equipment which it replaces.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above, PSEG concludes that the proposed amendment does not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of no significant hazards consideration is justified.

LAR H15-01 LR-N15-0178 47 of 47 5.3 Conclusions In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

6.0 ENVIRONMENTAL CONSIDERATION

A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or a significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
