Introduction:

The inspectors identified a Green finding and associated NCV of 10 CFR Part 50.49, "Environmental Qualification of Electric Equipment Important to Safety for Nuclear Power Plants," for failure to install conduit to environmentally qualified solenoid valves in a manner to prevent moisture intrusion and accumulation within the solenoid enclosure in accordance with Environmental Qualification file IH06, Revision 25.

Description

The team identified a Green, NCV of 10 CFR Part 50.49, Environmental Qualification, which states, in part, "(f) Each item of electric equipment important to safety must be qualified by one of the following methods:

(1) Testing an identical item of equipment under identical conditions or under similar conditions with a supporting analysis to show that the equipment to be qualified is acceptable."

Prior to June 18, 2018 the licensee failed to install four solenoids (1

-SV-474, 1-SV-455C, 1-SV-276, and 2

-SV-276) associated with power-operated relief Valves, as required by the Environment Qualification Binder IH

-06, ASCO Catalog NP Solenoid Valves. Specifically, the installed configuration did not match the tested configuration. The conduit connected to the solenoid housing must be oriented such that it prevents moisture intrusion and accumulation within the solenoid enclosure.

If the solenoid fails to energize, the power-operated relie f valves would not function as required during a feedwater break or low temperature overpressure transient.

This would cause a challenge to the pressurizer safety valves to relieve pressure in a feedwater line break accident or exceeding the pressure/temperature limits for a low temperature overpressure event. The licensee failed to correctly evaluate improper installation of the solenoids in 1995 when a walkdown was performed on the power-operated relief valve solenoids.

Based on the walkdown observations, engineering concluded that the existing configuration was acceptable to prevent water intrusion into the solenoid valve enclosure.

Based on questions asked during the environmental qualification inspection, the licensee re

-evaluated the conduit installation, and determined that the configuration did not comply with Equipment Qualification Binder IH

-06, ASCO Catalog NP Solenoid Valves.

Corrective Action(s): To gather more information as an input to the operability determination, the licensee performed a containment entry to physically walkdown the affected solenoid valves.

The walkdown confirmed that the orientation of the solenoids was not in accordance with Environmental Qualification Binder IH-06. The licensee has generated SAPN 50985639 to document the deficiency in the corrective action program.

The licensee has also performed an operability determination in which they found the solenoid valves operable.

Corrective Action Reference(s): SAPN 50985639, DA 50985639, AR A0374492, SAPN 50986204, SAPN 50986202, SAPN 50986203, SAPN 50986200 Performance Assessment

Performance Deficiency

The licensee failed to install equipment in the as

-tested configuration to demonstrate qualification as required by 10 CFR Part 50.49, Environmental Qualification

. Screening: The inspectors determined the performance deficiency was more than minor because was associated with the Design attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective. The objective of the Mitigating Systems cornerstone is to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

The performance deficiency adversely affected the cornerstone because the initially installed orientation of the environmentally qualified solenoid valves allowed them to be susceptible to moisture intrusion and therefore affected the availability, reliability, and capability of systems to respond to initiating events.

Significance

The inspectors assessed the significance of the finding using Inspection Manual Chapter 0609, Appendix A, "The Significance Determination Process for Findings At

-Power," dated June 19, 2012, Exhibit 2, "Mitigating Systems Screening Questions." The issue screened as having very low safety significance (Green) because it was a design or qualification deficiency that did not represent a loss of operability or functionality.

Cross-cutting Aspect

A cross-cutting aspect was not assigned for this violation because it is not indicative of current plant performance. The only time the licensee specifically evaluated the orientation of conduit to these solenoid valves was in 1995. Enforcement

Violation: 10 CFR Part 50.49, Environmental Qualification, states, in part, "(f) Each item of electric equipment important to safety must be qualified by one of the following methods:

(1) Testing an identical item of equipment under identical conditions or under similar conditions with a supporting analysis to show that the equipment to be qualified is acceptable."

Contrary to the above, prior to June 18, 2018 , the licensee ha d not installed the conduit to the solenoids in a configuration for which testing of an identical item of equipment under identical conditions or under similar conditions with a supporting analysis to show that the equipment to be qualified was acceptable."

Specifically, the licensee failed to install four solenoids (1

-SV-474, 1-SV-455C, 1-SV-276, and 2

-SV-276) associated with power operated relief valves, as required by the Environment Qualification Binder IH

-06, ASCO Catalog NP Solenoid Valves. The installed configuration did not match the tested configuration and would not have maintained equipment qualification against water intrusion. The conduit connected to the solenoid housing must be oriented such that it prevents moisture intrusion and accumulation within the solenoid enclosure.

If the solenoid fails to energize, the power operated relief valve would not function as required during a feedwater break or low temperature overpressure transient.

This would cause a challenge to the pressurizer safety valves to relieve pressure in a feedwater line break accident or exceeding the pressure/temperature limits for an low temperature overpressure event. Disposition:

This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy

.

EXIT MEETINGS DEBRIEFS On June 29, 201 8, the inspectors presented the inspection results to Mr. Adam Peck , Senior Director , Acting Station Director, and other members of the licensee staff. The licensee acknowledged the issues presented.

On July 25, 2018, a re-exit teleconference exit was held with Mr. Mark Sharp, Manager, Design Engineering and other members of the licensee staff, to clarify a change in the characterization of the identified finding. The inspectors verified no proprietary information was retained or documented in this report.
