14 14 Use of GEH PRNMS TR Use of GEH PRNMS TR
GEH PRNMS TR SE Report approved both the platform and application development process
GEH Digital Lifecycle Process - current platform deviates from the approved PRNMS TR:
APRM Upscale/OPRM Upscale, APRM INOP Function Logic Time to Calculate Flow-biased Trip Setpoint Abnormal Conditions Leading to Inoperative Status OPRM Pre-Trip Alarms Increased Instrument Security PRNM System Input Power Source Minor software changes below level of detail of LTR Lower level product enhancements (e.g., software change to support more efficient SR testing) and Error corrections in software
15 15 Application Development Process Application Development Process Case 1: If an NRC approved application development process exists:
NRC has already approved the application development process in the topical report and the underlying regulations have not changed since topical report approval, then ISG-6 Section D.4 has been addressed Case 2: If no NRC approved application development process exists:
The licensee has evaluated the vendors application development process and determined that the process is consistent with ISG-6 Section D.4 The LAR will describe the application development process consistent with ISG-6 Section D.4 At the Pre-application Coordination Meeting, one of these two cases will be discussed to address Section D.4. For GE PRNMS, it is Case 1. Note that this is a unique example in that it was NRC reviewed as part of a LAR for Hope Creek PRNM.
16 16 Additional NRC Topics of Interest Additional NRC Topics of Interest Data Communication (DI&C-ISG-04)
Diversity and Defense in Depth (BTP 7-19)
Secure Development & Operational Environment (RG 1.152)
Human Factors Considerations Application or Plant Specific Application Items Vendor (Technical) Oversight Plan The example Digital System Topic slides following are included to demonstrate level of detail
17 17 Data Communication (DI&C-ISG-04)
Data Communication (DI&C-ISG-04)
Interdivisional Communications PRNM design includes no channel-to-channel communications Supports the safety function of the system (voting)
PRNM includes NSR-to-SR communications Analysis will evaluate PRNM vs. 20 points in ISG-04 Command Prioritization Not applicable - the priority module (RPS) is not digital No diverse actuation signals are combined in PRNM Multidivisional Control & Display Stations ODAs are NSR, and utilize one-way communication from APRM/RBM NUMACs No control functions
18 18 Diversity and Defense in Depth (BTP 7-19)
Diversity and Defense in Depth (BTP 7-19)
Schedule for D3 Analysis submittal Prior to or with the LAR Preliminary review of HCGS UFSAR Chapter 15 shows significant overlap with CGS analysis Only minor Chapter 15 deltas were identified Will address all 9 criteria in BTP 7-19 Rev 6 Will rely on built-in diversity with other plant systems No requirement for a diverse actuation system is anticipated
19 19 EMC Compliance (RG 1.180)
PSEG procedures require EMC compliance for emissions and susceptibility Per PSEG procedure, EPRI TR-102323 and RG 1.180 contain acceptable testing standards PRNM is qualified to RG 1.180 limits HCGS environment is bounded by EPRI TR-102323 PRNM is located in a radio exclusion zone Comparison of equipment qualification to the plant specific envelope requirements Pre-qualified equipment, equipment to be qualified
20 20 Secure Development and Operational Environment (RG 1.152)
Secure Development and Operational Environment (RG 1.152)
GEH PSEG SDOE report is expected to be very similar to CGS report Report details GEH SDOE program from Concept through Test phases SOE after turnover of system to PSEG covered by PSEG Cyber Security Program (CSP)
HCGS is compliant with NRC approved cyber security plan License Amendments No. 189 and 192 SDOE Considerations PRNM will be at cyber security Level 4 CRIDS and 3DM remain at Level 3 - Application Firewall between Levels 3 & 4 Data Diodes installed between Level 3 and 2 - eliminating outside attacks from impacting Level 3 & 4 systems.
Gain Adjustment Factor (GAF) uploads performed through the Application Firewall
21 21 Human Factors Considerations Human Factors Considerations For PRNMS, there are no safety critical or accident mitigating operator actions Important operator tasks remain unchanged; therefore, there is no impact to task dynamics, complexity, or workload for the operations staff Two new actions related to the Simulated Thermal Power (STP) setpoint of the NUMAC APRMS and each has sufficient time to complete them Upgrade does not impact reactor operating parameters or the functional requirements of the APRM system System will continue to provide information, enforce control rod blocks, and initiate reactor scrams under appropriate specified conditions as before
22 22 Human Factors Considerations Human Factors Considerations The PRNM back panel equipment and NUMAC ODA has been designed to meet NUREG-0700 to the extent practicable Integrated system validation is not warranted, since no change in important human actions for the replacement hardware.
23 23 Plant Specific Action Items (PSAIs)
Plant Specific Action Items (PSAIs)
All PSAIs included as part of the generic approval of the GE Licensing Topical Report, NEDO-31439-A (October 1990), will be addressed as part of the LAR.
24 24 Vendor Oversight Plan (VOP)
Vendor Oversight Plan (VOP)
LAR will include a project-specific VOP description per ISG-06 R2 Section C.2.2.1 VOP includes participation by project stakeholders to ensure vendor compliance with their processes, including V&V, requirements traceability, configuration management, testing, software quality assurance, etc.
Vendor Oversight activities include the following:
Initial audit and review Periodic audits (which includes witness of critical testing or V&V activities)
Routine design reviews for technical and process compliance
