Performance of computer system restart operations shall not result in the safety system being inhibited from performing its function.

Self-diagnostics are one means that can be used to assist in detecting these failures. Fault detection and self-diagnostics requirements are addressed in this sub-clause.
The reliability requirements of the safety system shall be used to establish the need for self-diagnostics. Self diagnostics are not required for systems in which failures can be detected by alternate means in a timely manner. If self-diagnostics are incorporated into the system requirements, these functions shall be subject to the same V&V processes as the safety system functions.
If reliability requirements warrant self-diagnostics, then computer programs shall incorporate functions to detect and report computer system faults and failures in a timely manner. Conversely, self-diagnostic functions shall not adversely affect the ability of the computer system to perform its safety function, or cause spurious actuations of the safety function. A typical set of self-diagnostic functions includes the following:
Memory functionality and integrity tests (e.g.,
PROM checksum and RAM tests)
Computer system instruction set (e.g., calculation tests)
Computer peripheral hardware tests (e.g.,
watchdog timers and keyboards)

SE FSAR NRC No. Issue TVA Response(s) Acceptable Status/ Current Actions Resolution Path RAI No. & Date RAI Resp. Date Comments Sec. Sec. POC Y/N wide range temperature channels on RCS loops 1 and 2 provide inputs to the Eagle 21 digital process protection system. Eagle 21 provides isolated analog signals to the digital process control system. An auctioneer function selects the lowest temperature signal which is then used to calculate an acceptable reference pressure limit (PORV setpoint) considering the plants allowable pressure and temperature Protection Set III. The calculated reference pressure is compared to the actual RCS pressure monitored by the wide range pressure channel. The auctioneered temperature signal will annunciate a main control room (MCR) alarm whenever the measured temperature approaches, within a predetermined amount, the reference temperature for arming the system. Similarly, whenever the measured pressure approaches within a predetermined amount of the programmed setpoint, another MCR alarm will be generated.
When the measured RCS pressure is equal to or above the programmed setpoint (nominal values), a PORV open signal is initiated and a MCR alarm is actuated. A manually armed permissive allows this actuation signal to control the Train A PORV (PCV-68-340A). The manually armed permissive also serves to block a spurious PORV opening due to potential instrument failure whenever the RCS temperature is above the arming reference temperature.
The monitored generating station variables that generate the actuation signal for the Train B PORV (PCV-68-334) are processed in a similar manner. The RCS loops 3 and 4 wide range temperature signals and the RCS pressure signal are provided from Protection Set II. Therefore, the generating station variables used for the Train B PORV are derived from a protection set that is independent of the sets from which generating station variables used for the Train A PORV are derived. The wide range temperature auctioneer function and the programmed pressure setpoint calculation for the Train B PORV are performed in a different group of the digital process control system than those for the Train A PORV. Each of these control groups has a fault tolerant, redundant processor pair and redundant power supplies with different power sources.
FSAR Section 7.6.8.1 Analysis of Interlock describes the system conformance to IEEE-279. The design of the COMS as implemented in the Foxboro I/A system fully complies with FSAR section 7.6.8.1. Items (1) and (2) are implemented as part of the Eagle 21 modification. Item (3) is addressed by each processor pair having redundant power supplies with both being battery backed and ultimately backed by an ESF diesel generator.

WCAP process was acceptable. RSEDs are listed in the SDD References.
TVA Response:
Section 3.2.4.1 of WCAP-15927 describes the RSED design process for custom PC elements and type circuits. The Glossary of Terms in the SPM defines custom PC elements and type circuits as modules.
Therefore, the relationship between WCAP-15927 describing the RSED process as circuits, is defined in the SPM requirements for software module development.
WCAP-15927 is on the AP1000 docket.
