TVA Response:

Unnumbered paragraphs in the Post Accident Monitoring Systems Software Requirements Specification, such as in the section headings, are informative and are not to be interpreted as requirements. All requirements are explicitly numbered.

It depends on the document type. The statement would be true for requirements documents (such as the SysRS or SDS) if they were incorporated by reference.

However, for the specific item cited, WCAP-16096-NP-A, Rev. 1A, it does not contain numbered requirements.

The requirements contained in this document are contained within the text of the various sections.

a. Revision 3 of the SysRS, and SDS have been revised to use the terms FE keyswitch. Revision 3 of the SDS is consistent in use of the term ENABLE.
b. SysRS Revision 3 is not consistent in use of the term ENABLE as noted below:
i. R2.5.2.1-2 uses the term ENABLED instead of ENABLE ii. R2.5.2.1.3-3, R2.6.3.3-1, R2.6.3.3-2, R2.6.3.3-3, and R2.6.3.3-7, use the term Enable instead of ENABLE
c. Revision 3 of the SRS is not consistent in use of the terms FE keyswitch and ENABLE as noted below:
i. Tables 7.2-1 Train A PAMS Data Transmitted to the Plant Computer and 7.2-2 Train B PAMS Data Transmitted to the Plant Computer items 101 and 102 in the SRS refer to the FE switch.

All other items in the SRS refer to the FE keyswitch.

ii. Section 2.1, page 2-4, uses the term Enable instead of ENABLE iii. Requirements R7.2.14-6 and R7.2.16-7 use the term active instead of ENABLE iv. Requirements R7.2.23-2, R7.2.25-2, R7.2.26-2, R7.2.31-4, 7.2.56 FPDS Availability, and R7.2.57-4 use the term enabled instead of ENABLE

d. WNA-AR-00180-WBT-P, Revision 0, Failure Modes and Effects Analysis (FMEA) for the Post Accident Monitoring System, dated October 2010, submitted in TVA letter to NRC dated (Reference
12) is not consistent in use of the term FE keyswitch as noted below:
i. Section 2.2 System Description and Table 3-1 WB2 PAMS FMEA refer to the FE switch.

ii. Table 3-1 describes the switch as the Functional Enable (FE) switch and the FE key-switch

e. Revision 2 of the Licensing Technical Report is not consistent in use of the term FE keyswitch as noted below:

23. Westinghouse to resolve the following questions concerning Software Design Descriptions (SDDs)
a. Is the SDD a standalone document or will it incorporate the generic SDD by reference?
b. What are the SDDs?
c. PAMS is a delta document so how do we capture all the generic requirements for traceability.

TVA Response:

a. There are three SDDs prepared specifically for the Watts Bar 2 PAMS project. These are listed below in Item b. These documents and superior requirements documents refer to other generic SDDs also listed in Item b.
b. The SDDs developed for this project are:

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.

Appropriate bypass of one redundant channel is not considered an adverse effect in this context.

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.

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.
