Assessments
The report covered a 3-month period of inspection by resident and regional inspectors. There was one NRC-identified violation documented in this report. The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process,"
(SDP) dated April 29, 2015. The cross-cutting aspects are determined using IMC 0310,
"Aspects within the Cross-Cutting Areas," dated December 4, 2014. All violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy dated November 1, 2016. The NRC's program for overseeing the safe operations of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 6. Documents reviewed by the inspectors, not identified in the Report Details, are identified in the List of Documents Reviewed section of the Attachment.
Cornerstone: Mitigating Systems
- Green.
An NRC-identified non-cited violation (NCV) of Hatch Unit 1 Technical Specification 5.4, "Procedures," was identified when procedures did not include inspection criteria for ice buildup of the Unit 1 nitrogen storage tank piping. The licensee's failure to establish controls to ensure that ice buildup on the Unit 1 Containment Atmospheric Dilution (CAD) subsystem piping did not exceed ten inches was a performance deficiency. The licensee entered the condition into their corrective action plan as CR10296584, and performed de-icing activities to remove the ice buildup.
This performance deficiency was more than minor, because ice buildup on the CAD system may lead to CAD subsystem inoperability if left uncorrected. The finding screened as Green because the CAD subsystem remained operable. The inspectors determined that this finding had a cross-cutting aspect in the 'Initiation' aspect of the problem identification and resolution area, because the licensee did not initiate a condition report upon initially identifying the issue. [P.1] (Section 1R15)
REPORT DETAILS
Summary of Plant Status
Unit 1: Unit 1 began the inspection period at or near 100 percent rated thermal power (RTP).
On November 22, unit power was briefly reduced to 60 percent RTP to swap steam jet air ejectors. The unit was returned to 100 percent RTP and operated at or near 100 percent RTP through the remainder of the inspection period.
Unit 2: Unit 2 began the inspection period at 100 percent rated thermal power (RTP). On December 9, the unit entered end-of-cycle coast down and remained in coast down throughout
the remainder of the inspection period.

- CR 10296368 Icing buildup on nitrogen storage tanks
- CR 10308478 Drywell High Press ATTS card 2E11-N694D gross fail indication
b. Findings
Introduction:
An NRC-identified Green NCV of Hatch Unit 1 Technical Specification 5.4, "Procedures," was identified on November 8, 2016, when procedures did not include inspection criteria for ice buildup of the Unit 1 nitrogen storage tank piping.
Description:
On November 8, 2016, the inspectors identified ice buildup of eight inches in diameter on the Unit 1 nitrogen storage tank piping and six inches on the Unit 2 piping to the ambient vaporizer. The licensee determined the Unit 2 containment atmospheric dilution (CAD) subsystem was operable. However, the licensee did not initiate a condition report or perform an operability determination for Unit 1. On November 14, 2016, inspectors identified an accumulation of ice on the Unit 1 nitrogen storage tank piping of approximately ten inches. The licensee entered the issue into the corrective action program and performed de-icing activities. The licensee determined the Unit 1
subsystem was operable.
Procedure 34SO-T48-002, "Containment Atmospheric Control and Dilution Systems," stated "Ice formation on the piping at the Nitrogen Storage Tank greater than ten inches will cause excess stress on the piping and per engineering will require periodic de-icing."
The limitation on CAD system piping icing ensures piping/ice interactions during a postulated seismic event do not result in loss of function. However, only Unit 2 operator
rounds procedure OPS-1822, "U2 Inside R ounds Reactor BLDG," contained the guidance to confirm ice buildup less than eight inches and provided direction to declare the CAD subsystem inoperable if buildup was greater than ten inches in diameter. The licensee had not established similar controls for Unit 1 to ensure that de-icing activities would occur prior to buildup greater than ten inches for the Unit 1 CAD system. On November 9, 2016, the licensee entered the lack of icing inspections and limitations for Unit 1 into the corrective action program.
Analysis:
The failure to establish controls to ensure that ice buildup on the Unit 1 CAD subsystem piping did not exceed ten inches was a performance deficiency. This performance deficiency was more-than-minor, because ice buildup on the CAD system may lead to CAD subsystem inoperability if left uncorrected. The inspectors screened this finding using IMC 0609, Appendix A, "The Significant Determination Process (SDP) For Findings At-Power", dated June 19, 2012. The finding screened as Green per Section A of Exhibit 2, "Mitigating Systems Screening Questions," because the CAD subsystem remained operable. The inspectors determined that this finding had a cross-cutting aspect in the 'Initiation' aspect of the problem identification and resolution area, because the licensee did not initiate a condition report upon initially identifying the issue.
[P.1]
Enforcement:
Hatch Unit 1 Technical Specification 5.4.1 required, in part, that procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Appendix A, Section 1.h required, in part, that log entries be established for the operation of safety-related activities. Contrary to the above, the licensee did not establish log entry requirements for the operation of the Unit 1 CAD subsystem. Specifically, log entry requirements were not established in the Unit 1 operator rounds procedure to ensure that the buildup of excessive ice on the nitrogen storage tank piping would not occur. The condition existed from November 8, 2016 until November 14, 2016. The condition was entered into the licensee's corrective action program as CR10296584. This violation was treated as an NCV, consistent with the Enforcement Policy: NCV 05000321/2016004-01; "Failure to Establish Icing Controls on CAD Subsystem."

- verified modifications performed during plant configurations involving increased risk did not place the plant in an unsafe condition.
- evaluated whether system operability and availability, configuration control, post-installation test activities, and changes to documents, such as drawings, procedures, and operator training materials, complied with licensee standards and NRC requirements.
- reviewed a sample of related corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with modifications.
b. Findings
No findings were identified.
1R19 Post-Maintenance Testing
a. Inspection Scope
The inspectors either observed post-maintenance testing or reviewed the test results for the six maintenance activities listed below to verify the work performed was completed correctly and the test activities were adequate to verify system operability and functional capability.
- SNC 832959, 2E11N694D gross fail indication, December 15, 2016 The inspectors evaluated these activities for the following:
- Acceptance criteria were clear and demonstrated operational readiness.
- Effects of testing on the plant were adequately addressed.
- Test instrumentation was appropriate.
- Tests were performed in accordance with approved procedures.
- Equipment was returned to its operational status following testing.
- Test documentation was properly evaluated.
Additionally, the inspectors reviewed a sample of corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with post-maintenance testing.
b. Findings
No findings were identified.
