Subject:

Duke Energy Carolinas, LLC Oconee Nuclear Station, Units 1, 2, and 3 Docket Numbers 50-269, 50-270, and 50-287 Duke Comments on Draft NRC Safety Evaluation for Acceptance of the Oconee Reactor Protective System and Engineered Safeguards Protective System Digital Upgrade The Nuclear Regulatory Commission (NRC) provided a draft Safety Evaluation (SE) for Acceptance of the Oconee Nuclear Station (ONS) Reactor Protective System (RPS) and Engineered Safeguards Protective System (ESPS) Digital Upgrade to Duke Energy Carolinas, LLC (Duke) by letter dated October 23, 2009. Duke submitted the License Amendment Request (LAR) associated with this SE by letter dated January 31, 2008.

The letter transmitting the draft SE states that Duke must identify any factual errors or clarity concerns contained in the draft SE within 20 working days of the letter. Enclosure 1 provides comments on factual errors or clarity concerns. Duke marked up a copy of the draft SE identifying editorial comments and provided to the NRC Staff electronically on November 18, 2009.

Enclosure 2 provides comments to the portions of Section 3.6 that were identified as security sensitive in a November 5, 2009, Duke Letter. These portions of the draft SE describe design features that secure the ONS RPS/ESPS from electronic vulnerabilities. As such, Duke considers Enclosure 2 to be sensitive information and requests that it be withheld from public disclosure pursuant to 10 CFR 2.390.

If there are any questions regarding this submittal, please contact Boyd Shingleton at (864) 873-4716.

Enclosure 2 contains Security Sensitive Information-Withhold under 10 CFR 2.390.

Upon removal of Enclosure 2, this letter is uncontrolled.

revert to two of three trip or actuation logic, and the safety function will not be disabled." The discussion is intended to be generic for both systems but the SE is describing RPS (a 4 channel system) versus ESPS (a 3 channel system).

151 57 3.1.1.6.1.3 5 The draft SER describes the "...adequate diversity within the ATWS and data Correct acquisition system (DAS)..."

Need to clarify what SE is talking about. Definitely not data acquisition system.

The intent here is probably to mention AMSAC and DSS (ATWS mitigation systems) and DLPIAS and DHPIAS (diverse actuation systems).

152 57 3.1.1.6.1.3 2 10 The draft SER references "... Enclosure 2 of TSC 007-09, Supplement 13 Correct (Reference 71)."

The date on Reference 71 is November 2, 2002, should just be November 2002 as indicated on the test report. Would be better to refer to LAR Supplement 13 (Ref.

153 58 3.1.1.6.1.4 2 2 The draft SER states "Inthe TXS system proposed for use in the digital CHANGE to: "...In the TXS system proposed for use in RPS/ESPS, all interdivisional and safety to nonsafety communications is done the digital RPS/ESPS, all interdivisional and safety to using an SL21 daughter board attached the SVE2 safety function processor MSI communications is done using an SL21 daughter board."

157 62 3.1.1.6.1.11 1 3 This paragraph states that for the Oconee digital RPS/ESPS, the parameter Revise change enable keyswitch can provide a permissive to allow the SU to change operational modes of the safety channel without the channel being in-bypass or in trip. The licensee recognized this issue, and as described in Section 3.2 of this SE, plant procedures and administrative controls will restrict using the parameter change enable keyswitch to change from the standard operational mode without placing the affected division into bypass or trip.

Need to indicate that this is permissible for testing as described in the revised Response to RAI 80 and RAI EICB 106 provided inSupplement 18 (Ref. 19 of SE).

Also, it would be better to state the channel (Oconee does not use the term "division") is inoperable for parameter changes and bypassed for software updates 158 64 3.1.1.6.1.17 4 7 The draft SER states that "itshould be noted that this is not a generic approval, To avoid confusion as to the meaning of this limitation, and different nuclear power plants and different applications have different it would be better to link it to TXS Topical Report plant-environmental requirements.

The meaning of this statement is confusing.

Clarification is provided for information (no change is needed):

Section 3.3.1.1 of the SER notes acceptance of qualification that shows the cabinets bound control room temperature limits. The cabinet hi temp alarm will trip an RPS channel. The shutdown protects the system from exceeding the EQ temp limit. This is from the FMEA and is consistent with the description of the temp monitoring function inthe SBG3 Manual. A high temperature alarm will initiate a "CABINET FAULT" condition which will also turn "ON" the cabinet fault light at the top front and rear of the cabinet. The temperature alarm alerts the operator to high temperature inthe SBG3 power supplies and de-energizes all digital and analog outputs from the affected cabinets.

A high temperature cabinet alarm will trip the associated RPS or ESPS channel.

The shutdown protects the system from exceeding the EQ temp limit. The high temperature alarm will initiate a "CABINET FAULT" condition which will also turn "ON" the cabinet fault light at the top front and rear of the cabinet. The temperature alarm alerts the operator to high temperature in the SBG3 power supplies and de-energizes all digital and analog outputs from the affected cabinets.

Duke operator response will be to enter a TS LCO Condition for an inoperable channel and investigate the temp problem.
