INSPECTION RESULTS
Failure to Qualify GEMS Level Transmitters for Submergence Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None (NPP) 71111.21N Systems NCV 05000413,05000414/2019010-01 Open The inspectors identified a Green finding and Non-cited Violation (NCV) of 10 CFR 50.49(f)when the licensee failed to demonstrate the GEMS containment sump level transmitter NILT5270 would meet its specified values for one year post-accident during submerged conditions in accordance with Section 6.5.4 of IEEE 323-1974, the standard the licensee chose in order to meet environmental qualification requirements.
Description:
The purpose of GEMS level transmitter 1NILT5270 is to provide post-accident monitoring of Unit 1 containment sump level. EQMM-1393.01-P04-00, Environmental Qualification Maintenance Manual Equipment Type: Level Transmitter Manufacturer: Delaval, Gems Model/Series: XM54852, XM54853, XM60620, XM60625, Rev. 0, stated that the post-accident operating time for the transmitter was one year. The transmitters could be submerged in the containment sump solution during the one-year post-accident requirement.
During the review of the qualification package for the transmitter, the inspectors identified that the loss of coolant accident (LOCA) testing did not simulate submerged conditions and that the post-LOCA testing only simulated a submerged condition for 30 minutes. The inspectors also identified that the EQMM did not analyze how failing to submerge the transmitter during the LOCA test and for only 30 minutes during Post-LOCA testing proved the transmitters could perform their intended function for up to one year post accident.
Additionally, on August 25, 2016, a 10 CFR Part 21 Notification was supplied to the NRC by NTS Huntsville notifying NRC that the qualification tests for the GEMS transmitters did not simulate the submergence depth of 15-16 ft. to the junction box as stated during the 30 minute submergence test. The Part 21 notification stated that the wire conduit was not sealed to the test chamber, but instead was left unattached to the test chamber accident environment. As a result, the submergence test did not demonstrate the junction box gaskets ability to prevent moisture intrusion into the internal components of the GEMs transmitter. In response to the Part 21, the licensee completed an evaluation in AR 02149240 which stated that the GEMS transmitter remained qualified due to the silicon oil fluid in the transmitter acting as a general barrier between any potential moisture intrusion into the transmitter junction box and the junction box wiring internals and that the wiring and splices used in the junction box were installed using Raychem splice products which had been qualified as an EQ environmental seal boundary. Due to questions from the inspectors, the licensee reviewed their evaluation of the Part 21 notification and determined that the failure of the unqualified junction box seal could allow sump fluid to displace the oil and submerge subcomponents of the transmitter. The licensee determined that of the subcomponents installed, only the Raychem Spec 44-insulated transmitter lead wires were not demonstrated to be qualified for submergence in post-LOCA sump conditions by other test reports or analysis.
The EQMM stated that the transmitter was qualified in accordance with IEEE 323-1974.
Section 6.5.4 of IEEE 323 states, The electric equipment type shall be considered to be qualified by demonstrating that the equipment performance will meet or exceed its specified values for the most severe environment or sequence of environments in the equipment specification during its qualified life. The inspectors determined that the qualification package for the GEMS 1NILT5270 transmitter did not demonstrate its ability to perform its function under the most severe conditions (e.g., submergence).
Corrective Actions: The licensee entered this issue into their corrective action program and performed an operability evaluation which determined that there was reasonable assurance that the transmitter could perform its intended safety function based on operating experience and the military specification of the wire which demonstrated the insulations ability to withstand different adverse chemicals.
Corrective Action References: AR 02303851
Performance Assessment:
Performance Deficiency: The failure to demonstrate the GEMS level transmitter would meet its specified values for one year post-accident during submerged conditions in accordance with Section 6.5.4 of IEEE 323-1974, the standard the licensee chose in order to meet environmental qualification requirements.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to qualify the transmitter lead wires by testing or analysis for submergence did not ensure the wires could perform their function under wetted conditions for up to a year post accident.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors assessed the significance of the finding using Inspection Manual Chapter (IMC) 0609, Att. 4, "Initial Characterization of Findings," issued October 7, 2016, for the Mitigating Systems cornerstone, and IMC 0609, App. A, "The Significance Determination Process (SDP) for Findings At-Power," issued June 19, 2012, and determined the finding was of very low safety significance (Green) because the finding was a deficiency affecting the qualification of a mitigating structure, system, or component (SSC) and the SSC maintained its operability.
Cross-Cutting Aspect: Not Present Performance. No cross-cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.
Enforcement:
Violation: 10 CFR 50.49(f) required, "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.
- (2) Testing a similar item of equipment with a supporting analysis to show that the equipment to be qualified is acceptable.
- (3) Experience with identical or similar equipment under similar conditions with a supporting analysis to show that the equipment to be qualified is acceptable.
- (4) Analysis in combination with partial type test data that supports the analytical assumptions and conclusions."
Contrary to the above, since the earliest date of record for the EQMM package in 1991, the licensee failed to qualify the GEMS containment sump level transmitter NILT5270 for submergence by test or analysis for post-accident conditions of one year.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
Failure to Demonstrate Qualification of Conduit Sealant Compatibility for Electrical Wires and Cables Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None (NPP) 71111.21N Systems NCV 05000413,05000414/2019010-02 Open The inspectors identified a Green finding and associated Non-cited Violation (NCV) of 10 CFR 50.49(f) when the licensee failed to demonstrate the qualification of the conduit sealant and cable/wire interfaces utilizing Scotchcast Epoxy 9 in accordance with NUREG-0588 Section 2.2(7).
Description:
Duke EQ Files EQMM-1391.01-M01-01, Rev. 3 and CNM 1364.00-0007.001, Rev. D3 contained the licensee's basis for environmental qualification (EQ) of conduit seals utilizing Scotchcast Epoxy 9. In the EQ files, the licensee documented a test report that utilized the epoxy as a sealant to prevent moisture intrusion into equipment electrical conduits in accordance with Category II of NRC NUREG-0588. The focus of the testing was to demonstrate the sealing ability of the epoxy around a pair of tefzel-insulated wires in a Swagelock QF quick-connect pipe fitting by testing a mock-up conduit sealing configuration. The testing generally demonstrated the capability of the epoxy to provide a moisture barrier - but due to the use of de-energized wiring - failed to demonstrate that the interface between the epoxy and wires/cables installed in the field were compatible and capable of performing their functions of providing for the necessary transmission of signals or power. By not demonstrating that the sealant was compatible (i.e. did not adversely impact the electrical function of the wire/cable) with the field configurations, the licensee failed to demonstrate that the field configurations were qualified in accordance with 10 CFR 50.49.
For the conduit sealant locations in the station scoped into the licensee's EQ program, the licensee adhered to Category II requirements of NRC NUREG-0588 for qualification and qualification testing to meet 10 CFR 50.49. Section 2.2(7) of the NUREG states that "performance characteristics be verified before, after, and periodically during testing throughout the range of required operability." By testing the sealant's mechanical sealing function without confirming that the epoxy and wire/cable did not adversely impact their electrical function of passing power/signals to/from important to safety equipment, the licensee failed to demonstrate that the sealant was qualified for the installed configurations in the field.
Corrective Actions: The station entered this into their Corrective Action Program (CAP) as ARs 02300311 and 02303697. Although environmental qualification had not been demonstrated and documented, the licensee identified other tests that had been performed on other wire types with Scotchcast Epoxy 9 (e.g. NAMCO limit switch lead wire and Mark WPA 14 gauge hookup wire). The licensee's review of this additional testing provided reasonable assurance that the installed configurations in the plant would be capable of performing their intended safety functions.
Corrective Action References: AR 02300311 and 02303697
Performance Assessment:
Performance Deficiency: The failure to verify the Scotchast Epoxy 9 sealant cable/wire interface would meet its electrical performance characteristics before, after, and periodically during testing throughout the range of its required operability in accordance with Section 2.2.7 of NUREG-0588 (Category II) was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to ensure that the cable/wire interface with the sealant would not adversely impact the safety function fails to ensure the availability, reliability, and capability of the electrical equipment important to safety that must send or receive power/signals when challenged with the deleterious effects of aging and harsh environmental conditions.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors assessed the significance of the finding using Inspection Manual Chapter (IMC) 0609, Att. 4, "Initial Characterization of Findings," issued October 7, 2016, for the Mitigating Systems cornerstone, and IMC 0609, App. A, "The Significance Determination Process (SDP) for Findings At-Power," issued June 19, 2012, and determined the finding was of very low safety significance (Green) because the finding was a deficiency affecting the qualification of a mitigating structure, system, or component (SSC) and the SSC maintained its operability.
Cross-Cutting Aspect: Not Present Performance. No cross-cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.
Enforcement:
Violation: 10 CFR 50.49(f) required, "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.
- (2) Testing a similar item of equipment with a supporting analysis to show that the equipment to be qualified is acceptable.
- (3) Experience with identical or similar equipment under similar conditions with a supporting analysis to show that the equipment to be qualified is acceptable.
- (4) Analysis in combination with partial type test data that supports the analytical assumptions and conclusions."
Contrary to the above, since the qualification file for Scotchcast Epoxy 9 had been performed in 2001, the licensee failed to qualify the epoxy by any of the four methods described above.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
Failure to Assess Radiation and Thermal Degradation Effects of Replacement Sealant Equivalency Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [H.8] - 71111.21N Systems NCV 05000413,05000414/2019010-03 Procedure Open Adherence The inspectors identified a Green finding and Non-cited Violation (NCV) of 10 CFR 50.49(f)when the licensee failed to demonstrate that the qualification of Scotchcast Epoxy 9 was applicable to Scotchcast Epoxy 9N in accordance with Section 5.5.7 of procedure AD-EG-ALL-1612.
Description:
3M Corporation changed the chemical composition of the Part B of its Scotchcast Epoxy 9 two-part formulation from a nonylphenol component to formulation of cashew, nutshell liq.ccidentale, anacardiaceae, and toluene components. In 2018, the licensee generated an equivalency evaluation in engineering change EC 144757, Rev. 0 to evaluate the differences between the original formulation (Scotchcast Epoxy 9) and the new formulation (i.e. Scotchcast Epoxy 9N). The focus of the evaluation was to determine if the environmental qualification (EQ) performed for the original epoxy was applicable to the new epoxy. The licensee reviewed the material safety data sheets (MSDSs) of the two epoxies, performed durometer testing of representative samples of both epoxies, and performed Fourier Transform Infrared (FTIR) Spectroscopy to determine if the materials were similar enough to warrant the use of the Scotchcast Epoxy 9's qualification file to that of the Scotchcast 9N's. Based on a FTIR high percentage match (>80%) and similar durometer testing, the licensee concluded that the materials were similar enough and qualification of Scotchcast Epoxy 9 was applicable to Scotchcast Epoxy 9N.
The inspectors reviewed the engineering change and noted that FTIR spectroscopy and durometer testing would provide information showing similarity between the chemical constituents and discrepancies in hardness between the two epoxies (respectively), but neither test individually (nor combined) could provide detailed information on how these different epoxies would behave when subjected to the deleterious effects of nuclear radiation and thermal degradation (i.e. aging). Inspectors reviewed the licensee's EQ procedure, AD-EG-ALL-1612, Revs. 3 and 4, and noted that Section 5.5.7(11)(b)(4)(a) stated, in part, that:
"materials of construction shall either be the same or equivalent and differences shall be shown not to adversely affect performance of the safety function." Furthermore, the procedure states that the evaluations should, "evaluate the differences in material properties.
Minor chemical differences can cause significant variations in properties (e.g. radiation-withstand capability, dielectric strength, thermal aging, chemical interactions, and changes in material activation energy."
The licensee's technical review of the differences between the two epoxies lacked the necessary level of detail to demonstrate that the Scotchcast Epoxy 9N - which is chemically different - will age and withstand nuclear radiation in the same (or better) manner than the qualified Scotchcast Epoxy 9. As a result of the inspection, the licensee contacted 3M and determined that mechanical and electrical properties were similar between the two epoxies, however, no radiation or thermal degradation comparisons had been made between the materials.
Corrective Actions: The licensee entered this issue into their corrective action program (CAP)as AR 02303601. The licensee determined that the Scotchcast Epoxy 9N had only been used in four recent work orders and based on a review of the material data sheets and on the technical opinion of the licensee's subject matter experts, the licensee concluded that the four seals in question were capable of performing their safety function.
Corrective Action References: AR 02303601
Performance Assessment:
Performance Deficiency: The inspectors determined that the failure to perform an evaluation that appropriately considered the effects of nuclear radiation and thermal aging in accordance with procedure AD-EG-ALL-1612, Section 5.5.7(11)(b)(4)(a) was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to perform the necessary evaluation of Scotchcast 9N's capability to withstand nuclear radiation and thermal aging failed to ensure the reliability and capability of the Scotchcast Epoxy 9N to perform its safety function of protecting equipment important to safety from the deleterious effects of potential steam and moisture intrusion in the four locations where it had been applied to electrical conduits for the span of their designated life.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors assessed the significance of the finding using Inspection Manual Chapter (IMC) 0609, Att. 4, "Initial Characterization of Findings," issued October 7, 2016, for the Mitigating Systems cornerstone, and IMC 0609, App. A, "The Significance Determination Process (SDP) for Findings At-Power," issued June 19, 2012, and determined the finding was of very low safety significance (Green) because the finding was a deficiency affecting the qualification of a mitigating structure, system, or component (SSC) and the SSC maintained its operability.
Cross-Cutting Aspect: H.8 - Procedure Adherence: Individuals follow processes, procedures, and work instructions. This finding is indicative of current performance because the finding occurred within the last 3 years. This finding was assigned a cross-cutting aspect of H.8 because the licensee's failure to adhere to their EQ procedure AD-EG-ALL-1612, Section 5.5.7(11)(b)(4)(a) was the most significant contributor to the performance deficiency.
Enforcement:
Violation: 10 CFR 50.49(f) required, "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.
- (2) Testing a similar item of equipment with a supporting analysis to show that the equipment to be qualified is acceptable.
- (3) Experience with identical or similar equipment under similar conditions with a supporting analysis to show that the equipment to be qualified is acceptable.
- (4) Analysis in combination with partial type test data that supports the analytical assumptions and conclusions."
Contrary to the above, since the issuance of EC 144757 in 2018, the licensee failed to qualify the Scotchcast Epoxy 9N by any of the four methods described above.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
