RE: Rad Mon Questions I dont know what happened but I lost my numbering. This one is easier to read TVA has provided various documents in support of RM-1000 high range monitors for WBN2.

Please clarify the following:

RM-1000 v1.1 Software Verification Report 04508006 (Sequoyah)

RM-1000 v1.2 Software Verification Report 04508006 (Sequoyah)

RM-1000 System Verification Test Results (Sequoyah)

These documents were prepared for the Sequoyah plant. IS the version provided applicable to WBN2? Please confirm and explain if these documents are applicable to WBN 2 as provided or with differences?

The Sequoyah RM-1000 v1.1 Software Verification Report 04508006 and RM-1000 v1.2 Software Verification Report 04508006 are applicable to WBN Unit 2.

The RM-1000 System Verification Test Results report is not applicable to WBN Unit 2. This document was for the non-safety related software and was superseded by the 04508006 v1.1 and v1.2 reports for the safety-related software.

TVA has provided a proprietary and a non-proprietary version of Technical Manual for RM-1000 Digital Radiation Processor under ML101680582 and ML101680587).

(i)

Are these documents applicable to WBN2 as provided (October 2003 version).

(ii)

Why is DCN38993-A attached at the back of the proprietary version? It is for WBN1 Turbine Governor Control Valve.

(iii)

This document does not state the requirements for RM-1000 units. Please provide a document that states the requirements for the RM-1000 radiation monitors for WBN2.

(i)

These documents are applicable to WBN Unit 2.

(ii)

This was an error in document preparation that occurred when attachments were assembled for a previous letter.

(iii)

The Technical Manual is not intended to include equipment requirements.

Requirements would be found in the applicable TVA Specifications for the contract.

TVA has provided the following documents for RM-1000 equipment qualification:

(i)

Qualification Test Report for RM-1000 Processor Module and Current-To-Frequency Converter 04508905-QR (January 2001)

(ii)

Qualification Test Report Supplement, RM-1000 Upgrades 04508905-1SP (June 2006)

(iii) Qualification Test Report Supplement, RM-(i)

Applicable to WBN Unit 2. 04508905-1QR is applicable only in regards to the RM-1000, with the exception of re-qualification of certain RM-1000 equipment differences covered in the -1SP report. The Current-to-Frequency (I-F) converter module qualifications in the base report and the -1SP report are not applicable to the RM-1000s, and will be used later as references in the WBN Unit 2 specific

(ii)

Applicable to WBN Unit 2.

(iii) Not applicable to WBN Unit 2 (iv) Not applicable to WBN Unit 2 The 04508905-3SP report was prepared for another TVA plant, as a monitor system-level report, where the system included equipment mostly based on the base report equipment items.

These two -2SP and -3SP supplement reports were essentially worked concurrently, but the -2SP document review/release process resulted in the release time difference.

TVA provided System Verification Test Results 04507007-1TR (July 1999) for Sequoyah to support test verification. However, the document states (page v) that it is not applicable for high range monitors with an action noted for fixing a problem with the high range RM-1000 monitors on page vi.

TVA to respond to the following clarifications:

Has the anomaly noted on page vi been resolved for the high range monitors?

Provide the high range verification document for WBN2.

See Response to letter item __ (RAI Matrix Item 316) for non-applicability of 04507007-1TR. The recorded anomaly was later resolved through the verification of software version 1.2, reported in RM-1000 v1.2 Software Verification Report 04508006.

The high range verification documents are the Sequoyah RM-1000 v1.1 Software Verification Report 04508006 and RM-1000 v1.2 Software Verification Report 04508006.

RE: Rad Mon Questions

Dale, Following is our response to the Rad monitors questions, Item Numbers 316, 317, 318, 319.

1.

1. The first two documents listed are directly applicable to WBN2 RM-1000s, as the code version results are applicable to both the present WBN2 safety-related contract, and to any future SQN safety-related RM-1000 contract. The System Verification Test Results 04507007-1TR is not applicable to WBN, because it is only applicable to Sequoyah non-safety-related RM-1000s. The 04507007-1TR report was requested by TVA/SQN, when TVA suspended GA-ESI work on the safety-related portion of the SQN contract in work for RM-1000s. This 04507007-1TR report was solely used by TVA to provide a level of software verification commensurate with their application of non-safety-related RM-1000s in the SQN contract, leaving GA-ESI to later continue with safety-related verification separately. This later GA-ESI work developed the safety-related software verification, including a Critical Digital Review by TVA, where RM-1000 software Version 1.1 was approved by TVA for future safety-related procurement. And, this work produced the first two listed documents, that are the applicable results documents for the deliverable WBN2 safety-related RM-1000s.

2.

2. i. These documents are applicable iii. The iii. Technical Manual is not intended to include equipment requirements. Requirements would be found in the applicable TVA Specifications for the contract.

3.

3. With regards to the RM-1000 modules, the first two documents are applicable to WBN2, but not the 04508905-2SP and 3SP documents. The base document 04508905-1QR is applicable only in regards to the RM-1000, with the exception of re-qualification of certain RM-1000 equipment differences covered in the -1SP report. The Current-to-Frequency (I-F) converter module qualifications in the base report and the -1SP report are not applicable to the RM-1000s, and will be used later as references in the WBN2-specific qualification reports. The 04508905-3SP report was prepared for another TVA plant, as a monitor system-level report, where the system included equipment mostly based on the base report equipment items. These two -2SP and -3SP supplement reports were essentially worked concurrently, but the -2SP document review/release process resulted in the release time difference.

4.

4. See Response 1 for non-applicability of 04507007-1TR. However, the recorded anomaly was resolved later, through the verification of software version 1.2, reported in 04508006.
