In previous letters TVA has provided the Common Q documents that address this item:

38 Please provide a description of the interfaces between: (1) the Safety Parameter Display System and (2) the Technical Support Center and Nuclear Data Links with the plant control and safety systems. This Description should contain sufficient detail to support a review of these interfaces using current staff positions.

TVA Letter dated March 12, 2010 Enclosure 1, item 4 responded to this request for information.

37 Is the plant computer a safety-related display system?

As identified in TVA letter dated March 12, 2010, Enclosure 1, item 2, the plant computer system is non-safety related.

FSAR section 7.5 describes both safety and non-safety related devices and systems. A revision to FSAR section 7.1.1.2 will be developed for amendment 100 to clarify that 7.5 applies to both safety and non-safety related equipment.

39 Please describe the change to the calculation of the estimated average hot leg temperature (see FSAR Section 7.2.1.1.4, page 7.2-14 Version WBNP-96) in sufficient detail to support a review of this system using current staff positions.

Refer to revised equations in FSAR amendment 98.

The slides presented at the December 15, 2010 meeting (ML093520967) indicate that the plant process computer has been replaced.

The equation for the calculation of the estimated average hot leg temperature on page 7.2-13 of Revision WBNP-96 of the Unit 2 FSAR is different than the calculation of the average hot leg temperature shown at the top of page 7.2-14 of version WBNP-1 of the UNIT 1 FSAR.

administrative programs that are unique to Unit 2 should be reviewed in accordance with the current staff positions. Unit 2 FSAR Section 7.6.7, Loose Part Monitoring (LPMS) system Description, describes a system design that is unique to Unit 2.

FSAR Section 7.5.1, SE Section 7.5.2 NNC: Unit 2 FSAR Section 7.5.1, Post Accident Monitoring Instrumentation, describes a system design that is unique to Unit 2. LIC-110, "Watts Bar Unit 2 License Application Review," states: "Design features and administrative programs that are unique to Unit 2 should then be reviewed in accordance with the current staff positions."

FSAR Section 7.5, Instrumentation System Important to Safety, consists of two major subsections: 7.5.1, Post Accident Monitoring Instrumentation (PAM), and 7.5.2, Plant Computer System.

Regulatory Guide 1.70, Standard format and content of Safety Analysis Reports for Nuclear Power Plants, Revision 3 dated November 1978 states (see Section 7.1.1): List all instrumentation, control, and supporting systems that are safety-related including alarms, communication, and display instrumentation. FSAR Section 7.1.1.2, Safety-Related Display Instrumentation, describes, in the first paragraph, the PAM system, and the second paragraph states: All other safety-related instrumentation is discussed in Section 7.5. Therefore, to be consistent with the preceding paragraph, the FSAR states that the plant computer system is safety related.

Contrary to the FSAR the slides presented at the December 15, 2010 meeting indicate that the plant process computer is not safety-related. Therefore the docketed material is inconsistent and needs to be clarified.

Need revised compliance matrix 44 The PAMS ISG6 compliance matrix supplied as to TVA letter dated February 5, 2010 is a first draft of the information needed.

By letter dated April 8, 2010 TVA provided the PAMS Licensing Technical Report provided additional information.

The revised Common Q ISG-6 Compliance Matrix is attached.

42 On December 16, 2009: EICB stated to DORL: "I am having trouble reading the drawings in the binder that was given to me. Is it possible to produce a set of full size drawing that are in the FSAR?"

On February 23, 2010: EICB received a set of enlarged Chapter 7 FSAR pages (drawings) that are still unreadable.

This type of delay and quality is unacceptable for someone who is concerned about schedule. Please produce a large and legible set of drawing that are the ones in Chapter 7 of the FSAR. provides a drawing cross reference list for FSAR Chapter 7 and electronic copies of the fully legible current drawings previously submitted in full size hard copies.

TVA provided readable drawings.

43 The PAMS ISG6 compliance matrix supplied as Enclosure 1 to TVA letter dated February 5, 2010 is a first draft of the information needed. The shortcomings of the first three lines in the matrix are:

Line 1: Section 11 of the Common Q topical report did include a commercial grade dedication program, but this program was not approved in the associated SE. Westinghouse stated that this was the program and it could now be reviewed. The NRC stated that TVA should identified what they believe was previously reviewed and approved.

Line 2: TVA stated the D3 analysis was not applicable to PAMS, but provided no justification. The NRC asked for justification since SRP Chapter 7.5 identified SRM to SECV-93-087 Item II.Q as being SRP acceptance criteria for PAMS.

Line 3: TVA identified that the Design report for computer integrity was completed as part of the common Q topical report. The NRC noted that this report is applicable for a system in a plant, and the CQ topical report did no specifically address this PAMS system at Watts Bar Unit 2.

NRC then concluded that TVA should go through and provide a more complete and thorough compliance matrix.

The equation for the calculation of the power fraction on page 7.2-14 of Revision WBNP-96 of the Unit 2 FSAR is different than the calculation of the power fraction shown at the top of page 7.2-14 of version WBNP-1 of the UNIT 1 FSAR.

FSAR Section 7.5.1 Post Accident Monitoring Instrumentation - SE Section 7.5.2 The drawing provided did not have the identification numbers as in the FSAR. It is interesting that TVA does not have a readable version of the drawings in the FSAR.

Reference 4 has been changed to ISA-DS-67.04-1982. Justify applicability of this standard for WBN 2. Why the latest ISA standard endorsed by NRC has not been used? Also reference 5 is a topical report for Eagle 21, system. Please confirm that this topical report also discusses the setpoint for Eagle 21 system and whether it meets the recent guidance for the setpoint issued by the staff. Also, W setpoint methodology do not provide discussion on the AS Found Tolerance and As left value determination and how these values are used for the instrument operability, therefore, add the discussion of these topics in the FSAR. and add reference to other documents if it is discussed in some other document. Provide this document to the staff for review and approval This item will be addressed in FSAR amendment 100.

Safety Related System Non Safety Related Interface Unit 1 Review Eagle 21 Plant Computer (ICS)

While Eagle was installed prior to Unit 1 Licensing, the interfaces to the ERFDS/P2500 main frame computers were analog. With the replacement of the ERFDS/P2500 mainframes by the Integrated Computer System (ICS), the interface became digital. Since ICS was installed under 50.59 the Unit 1digital communications interface has not been reviewed.

Common Q Plant Computer (ICS)

Common Q is not installed in Unit 1

Unit 2 Interface Review The digital Eagle to ICS interface in Unit 1 is via node boxes on a ring network. The interface for Unit 2 is direct from the Eagle cabinets to a network switch on a star network. While the Unit 2 ICS computer hardware interface is different than Unit 1, the Eagle interface is the same in both units; via a mono-directional communication path described in Reference 1. Due to the difference in the ICS connection, the Unit 2 interface is unique.

The Common Q to Plant Computer interface is via the safety related Maintenance and Test Panel (MTP) fiber optic interface which blocks all except the minimum low level TCP/IP commands necessary to support communications. A detailed description of the MTP communications is contained in WNA-LI-00058-WBT, Revision 0, Watts Bar Unit 2 (WBN2) Post Accident Monitoring System (PAMS) Licensing Technical Report submitted under Reference 2. Additional communication isolation is provided by non-safety related data diodes (one for each train). The Common Q to ICS interface is unique to Unit 2.
