SUBJECT:

LIMERICK GENERATING STATION, UNITS 1 AND 2 - CYBER SECURITY INSPECTION REPORT 05000352/2020401 and 05000353/2020401

Dear Mr. Hanson:

On January 30, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Limerick Generating Station, Units 1 and 2. The NRC inspectors discussed the results of this inspection with Mr. Martin Bonifanti, Plant Manager, and other members of your staff. The results of this inspection are documented in the enclosed report.

NRC inspectors documented one finding of very low safety significance (Green) in this report.

This finding involved a violation of NRC requirements. The NRC is treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2.a of the Enforcement Policy.

A cross-cutting aspect was assigned to a finding in the area of Human Performance.

Specifically, Teamwork, because Exelon failed to communicate and coordinate their activities within and across organizational boundaries to ensure cyber security is maintained, [H.4].

If you contest the violation or significance of this NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement; and the NRC Resident Inspector at Limerick. In addition, if you disagree with the cross-cutting aspect assignment, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the U. S. Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, DC, 20555-0001; with copies to the Regional Administrator, Region I and the NRC Resident Inspector at Limerick.
