- (1) Unplanned plant shutdown March 8 to 9, 2018, due to a current transformer failure on the main generator outgoing power line
INSPECTION RESULTS
Minor Violation 71152 Follow
-up of Selected Issues Minor Violation: Title 10 of the Code of Federal Regulations (10 CFR) 50.65 (a)(2) allows safety system structure and components to not be monitored under 10 CFR 50 (a)(1), if an adequate demonstration that system performance is being maintained through effective maintenance is provided. In order to demonstrate this, Maintenance Rule availability performance criteria and reliability performance criteria are established and select ed in accordance with Exelon procedure ER
-AA-310-1003 , "Maintenance Rule
- Performance Criteria Selection." Section 4.4, "Selecting Reliability Performance Criteria,"
3, "Process for Selecting Reliability Performance Criteria," contains a process to be used in which a criteria greater than or equal to two is acceptable with documentation of past performance. Contrary to the above , two maintenance rule systems contained criteria greater than or equal to two without documentation of past performance in the "Basis and Justification for Criteria Values" section of the maintenance rule basis document.
Thus, an adequate technical basis was not documented for a required 10 CFR 50.65 (a)(2) performance criteria in accordance with Exelon's procedures.
Screening:
The inspectors independently evaluated the deficiency for significance in accordance with the guidance in IMC 0612, Appendix B, "Is sue Screening," issued December 31, 2017, and Appendix E, "Examples of Minor Issues," issued August 11, 2009. The inspectors determined that not documenting the past performance , which was used to determine the reliability criteria
, was a deficiency of minor significance since the criteria selected did not require a maintenance rule a(1) evaluation. As a result it is not subject to enforcement action in accordance with the NRC's enforcement policy. This issue was captured in Exelon's Corrective Action Program as A R 04126470 and 02658070
.
Enforcement:
This failure to comply with procedure ER
-AA-310-1003 , Revision 5, constitutes a minor violation that is not subject to enforcement action in accordance with the NRC's Enforcement Policy.
EXIT MEETING S AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On March 22, 2018, the inspectors presented the inspection results related to IP 71124.02 to Mr. William Carsky, Site Vice President, and other members of the Ginna staff.
On April 16, 2018, the inspector s presented the integrated quarterly resident inspector report inspection results to Mr. William Carsky, Site Vice President and other members of the Ginna staff.

. INSPECTION RESULTS
Minor Violation
71152 Follow
-up of Selected Issues Minor Violation: Title 10 of the Code of Federal Regulations
(10 CFR) 50.65 (a)(2) allows safety system structure and components to not be monitored under 10 CFR 50 (a)(1), if an adequate demonstration that system performance is being maintained through effective maintenance is provided. In order to demonstrate this, Maintenance Rule availability performance criteria and reliability performance criteria are established and select ed in accordance with Exelon procedure ER
-AA-310-1003 , "Maintenance Rule
- Performance Criteria Selection." Section 4.4, "Selecting Reliability Performance Criteria,"
3, "Process for Selecting Reliability Performance Criteria," contains a process to be used in which a criteria greater than or equal to two is acceptable with documentation of past performance. Contrary to the above , two maintenance rule systems contained criteria greater than or equal to two without documentation of past performance in the "Basis and Justification for Criteria Values" section of the maintenance rule basis document.
Thus, an adequate technical basis was not documented
for a required 10 CFR 50.65 (a)(2) performance criteria in accordance with Exelon's procedures.
Screening:
The inspectors independently evaluated the deficiency for significance in accordance with the guidance in IMC 0612, Appendix B, "Is
sue Screening," issued December 31, 2017, and Appendix E, "Examples of Minor Issues," issued August 11, 2009. The inspectors determined that not documenting the past performance , which was used to determine the reliability criteria
, was a deficiency of minor significance since the criteria
selected did not require a maintenance rule a(1) evaluation. As a result it is not subject to enforcement action in accordance with the NRC's enforcement
policy. This issue was captured in Exelon's Corrective Action Program
as A R 04126470 and 02658070
. Enforcement: This failure to comply with procedure ER
-AA-310-1003 , Revision 5, constitutes a minor violation that is not subject to enforcement action in accordance with the NRC's Enforcement Policy.
