SUMMARY
OF PUBLIC MEETING On March 22, 2017, at 6:00 p.m., the U.S. Nuclear Regulatory Commission (NRC) met with the Connecticut Nuclear Energy Advisory Council (NEAC) at the Waterford Public Library in Waterford, Connecticut. The NRC conducted the meeting to discuss its assessment of the safety performance at Millstone Power Station for 2016.
A notice of the NRC and NEAC meeting was issued on March 9, 2017, and was posted on the NRCs external (public) Web page. The meeting notice can be found in the NRCs Agencywide Documents Access and Management System (ADAMS) with Accession Number ML17068A058.
ADAMS is accessible from the NRC Web page at: http://www.nrc.gov/reading-rm/adams.html.
The NRC discussed its assessment of the safety performance of Millstone Power Station for the period of January 1 through December 31, 2016, as documented in our letter dated March 1, 2017 (ADAMS Accession Number ML17059D364). Additional information relative to the NRC's Annual Assessment Process and the safety performance of Millstone Power Station can be found on the NRC's web site at: https://www.nrc.gov/reactors/operating/oversight.html.
Members of NEAC, the public, and members of the media attended the meeting and were offered the opportunity to question the NRC regarding Dominions performance and the role of the agency in ensuring safe plant operations. Some of the questions required additional research with technical experts within the NRC. The answers regarding these topics are included as an enclosure to this letter.

Interpolating the data from the calculated model, the present heat load is approximately 1.0MBTU/hr.

LEL is defined as 4 percent of Hydrogen in the atmosphere.
Millstone allegations data and trends The 2016 Allegation Program Annual Trend Report is expected to be issued by the end of April 2017. The 2015 Allegation Program Annual Trend Report can be found at the following website:
https://www.nrc.gov/docs/ML1611/ML16119A431.pdf Quantified reliability of the Unit 3 Turbine Driven Auxiliary Feedwater pump In addition to the baseline inspection program, the NRC utilizes voluntary performance indicators (PI) to quantitatively assess licensee performance. Within this framework lies the Mitigating Systems Performance Index (MSPI), which is a monitor of the readiness of important safety systems to accomplish their safety functions in response to analyzed events. It objectively establishes unavailability and unreliability indices, UAI and URI respectively, by evaluating actual availability and reliability data for each monitored system against industry standards and unit specific performance limits over the last three years. The UAI and URI values are summed to establish the MSPI for each monitored system as a simplified core damage frequency which can be compared on scale from Green (nominal) through Red (significant decline in performance).
NRC Inspection Manual Chapter 0608, Performance Indicator Program, and Inspection Procedure 71151, Performance Indicator Verification, provide additional details for determining UAI, URI, and MSPI for a specified system. These are located in the NRCs inspection manual and are available at the following website:

The individuals were assigned a mentor and instructor to work on Job Performance Measures (JPMs) that were missed during the examination and additional JPMs to improve any performance gaps. The individuals successfully passed the subsequent examinations following remediation.
