Subject:

Request for Approval of the Revised Watts Bar Nuclear Plant Cyber Security Plan (CSP) and associated Watts Bar Nuclear Plant Unit 1 License Condition (WBN-TS-15-005)

Reference:

Letter from NRC to TVA, "Watts Bar Nuclear Plant - NRC Inspection of Unit 1 Cyber Security Milestones, Inspection Report No. 05000390/2014405, Inspection of Unit 2 Implementation of the Cyber Security Program Requirements, Inspection Report No. 05000391/2014406, and Enforcement Discretion," dated September 8, 2014 [ML14252A491]. The purpose of this letter is to request U.S. Nuclear Regulatory Commission (NRC) approval of a proposed change to the Watts Bar Nuclear Plant (WBN) Cyber Security Plan (CSP), clarifying the demarcation point between regulatory jurisdiction for certain assets, based on function not physical location. The change to the WBN CSP requires changing the associated WBN Unit 1 License Condition E.(2). As discussed in the referenced letter, the NRC identified an unresolved item associated with the demarcation point (Bright-Line) between digital components within the scope of the WBN CSP, under NRC jurisdiction, and those under the jurisdiction of the North American Electric Reliability Corporation (NERC). To aid in resolution of this issue, Tennessee Valley Authority (TVA) is providing, in Enclosure 1, an illustration of the "Bright-Line" between the critical digital assets that are in the scope of the WBN CSP and those that are under NERC jurisdiction. contains a revised CSP incorporating the necessary information contained in into the CSP. Enclosure 3 provides a proposed revision to WBN Unit 1 Facility Operating License Condition E.(2) associated with the WBN CSP.
