05000338/2019010 AND 05000339/2019010

Dear Mr. Stoddard:

On June 7, 2019, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at

your North Anna Power Station, Units 1 and 2 and discussed the results of this inspection with

Larry Lane, Site Vice President, and other members of your staff. On July 18, 2019, a re-exit

meeting was conducted, and the results were discussed with Jim Jenkins, Director of Safety

and Licensing at North Anna, and other members of the licensee staff. The results of this

inspection are documented in the enclosed report.

Two findings of very low safety significance (Green) are documented in this report. Two of these

findings involved violations of NRC requirements. We are treating these violations as non-cited

violations (NCVs) consistent with Section 2.3.2.a of the Enforcement Policy.

If you contest the violations or significance or severity of the violations documented in this

inspection report, you should provide a response within 30 days of the date of this inspection

report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, DC 20555-0001; with copies to the Regional

Administrator, Region II; the Director, Office of Enforcement; and the NRC Resident Inspector at

North Anna.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in

effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with

their attached revision histories are located on the public website at http://www.nrc.gov/reading-

rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared

complete when the IP requirements most appropriate to the inspection activity were met

consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection

Program - Operations Phase. The inspectors reviewed selected procedures and records,

observed activities, and interviewed personnel to assess licensee performance and compliance

with Commission rules and regulations, license conditions, site procedures, and standards.

71111.21N

The inspectors identified a Green finding and associated Non-cited Violation (NCV) of 10

CFR 50.49(e)(3) when the licensee failed to qualify all 10 CFR 50.49 electrical equipment for

the most severe chemical effects expected in containment.

Description: During design basis accidents in which equipment important to safety must

perform their safety function, the quench spray (QS) system actuates to reduce pressure and

4

temperature in containment. The QS system is designed to take water from an internal weir

inside the refueling water storage tank (RWST) and pump it to spray rings inside

containment. The sprayed water reduces the temperature and pressure associated with the

design basis accident. The sprayed water from the QS system also provides a certain amount

of "iodine scrubbing" to the containment atmosphere in which postulated radioactive iodine

would be captured by the water as it fell, entrapping it in solution. To accomplish this, the

water is buffered with sodium hydroxide (NaOH) to a basic pH (pH > 7.0).

The design of the QS system includes a 5-minute time delay for sodium hydroxide injection

into the RWST. By licensee calculations and UFSAR Section 6.2.3.1.1, the initial spray pH in

containment prior to the mixing of sodium hydroxide in the spray could be as low as 4.7. The

licensees environmental zone description describes the chemical spray as 8.6-10.6 pH from

0-4 hours then 7-8.6 from 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to termination of sprays.

The result of this discrepancy is that the licensee has never qualified any equipment inside

containment for this initial chemical spray condition in which only diluted boric acid is being

sprayed into containment. The initial period of spray could be significant because, even

though the duration of exposure to the acidic conditions would be relatively short, the

equipment in containment would absorb (be wetted) and potentially retain the acidic solution

throughout the accident.

An inspection sample, BIW 300 V instrument cable, was reviewed by the inspectors to

determine if any chemical incompatibility existed between the materials of construction and

the diluted boric acid. Using various chemical compatibility tables, the inspectors determined

that the neoprene jacket could be adversely affected by the effects of the boric acid spray.

Corrective Actions: The licensee gathered additional information from other nuclear utilities

and was able to conclude that the various components in containment were functional. The

licensee entered this issue into their corrective action program and plans to perform the

required analysis or testing to demonstrate that all equipment that must conform to 10 CFR

50.49 is qualified for the licensee's containment spray conditions.

Corrective Action References: CR 1123701

Performance Assessment:

Performance Deficiency: The licensee's failure to qualify equipment inside containment

subject to 10 CFR 50.49 to the most extreme chemical environment was a performance

deficiency. Specifically, Division of Operating Reactors (DOR) Guidelines Sections 4.1.4 and

4.2.4, NUREG-0588 Section 1.3, and Institute of Electrical and Electronics Engineers (IEEE)

Std. 323-1974 Section 6.3.6 state that the equipment to be qualified should be demonstrated

to be qualified (by test) for the most severe caustic environment it is expected to see given

the most limiting single failure.

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. Specifically, the failure to qualify 10 CFR 50.49 equipment in

containment for the most severe chemical composition of containment spray fails to ensure

the reliability and capability of those components to perform their safety function when called

upon during a design basis accident.

5

Significance: The inspectors assessed the significance of the finding using IMC 609,

Appendix A, The Significance Determination Process (SDP) for Findings At-Power.

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(e)(3) requires, in part, that qualification of electrical equipment

important to safety be based on the composition of chemicals at least as severe as that

resulting from the most limiting mode of plant operation.

Contrary to this, since February 2, 1983, the licensee failed to base qualification on the

composition of chemicals at least as severe as that resulting from the most limiting mode of

plant operation when they failed base qualification of electrical equipment important to safety

inside containment on the composition of chemicals at least as severe as that resulting from

the most limiting mode of plant operation.

Enforcement Action: This violation is being treated as an NCV, consistent with Section 2.3.2

of the NRC Enforcement Policy.

71111.21N

The inspectors identified three examples of a Green finding and associated Non-cited

Violation (NCV) of 10 CFR Part 50, Appendix B, Criterion III when the licensee failed to verify

compliance with environmental qualification (EQ) requirements in accordance with design

control manual NDCM-3.3 Rev. 11, Design Verification.

Description:

Example 1:

For Units 1 and 2, the licensee failed to verify that post-accident Arrhenius calculations

demonstrated the required post-accident-operating-time (PAOT) of 120 days for 300V Boston

Insulated Wire (BIW) instrument cables.

Specifically, the licensees Plant Qualification Evaluation (PQE) NA-EQUAL-000-PQE-06.02-

P01, Boston Insulated Wire & Cable Co. XLPE/NEO 300 V Instrument Cable. Rev. 1,

verified that the site EQ requirements were met by the qualification testing documented in

BIW qualification report 8714. The BIW report specified that unaged cable samples were

subjected to loss-of-coolant-accident (LOCA) simulations, including PAOT, for approximately

34 hours3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br />. The PQE evaluation of the BIW cable testing, however, incorrectly based

qualification on a test duration that lasted more than 400 days. When inspectors informed the

licensee of this error, the licensee re-ran their PAOT calculation and determined that the

cables could not meet their PAOT mission time.

6

Example 2:

For Units 1 and 2, BIW 300 V instrument cables were identified as deficient in aging for

qualified life in NRC safety evaluation reports (SERs) in 1983. The licensee claimed a

qualified life of 40 years, which was not supported by the cable qualification documentation.

The qualification test used unaged cable for the LOCA testing even though the cable was

identified as being vulnerable to the deleterious effects of thermal aging. In response to the

SERs, the licensee devised a surveillance and maintenance schedule to monitor cables and

replace them as needed. Sometime after the NRC concern was closed, the licensee

determined that surveillance was not practical and decided to determine a qualified life.

Since the cables were not aged prior to testing to establish a qualified life, the licensee used

the vendor-supplied thermal regression line to determine a qualified life in excess of 73 years.

Fundamentally, a regression line, alone, is insufficient to determine a qualified life because it

does not account for a design basis accident at the end of life plus a PAOT of 120 days.

These cables must perform their safety functions at the end of a lifetime of radiation aging,

thermal aging, and other aging effects during and following design basis accidents for a

minimum of 120 days. The license failed to verify that their calculational methods met their

design control requirements.

Example 3:

Initially, the licensee utilized information from Conax testing (aging time, aging temperature)

and a science paper published in the Society of Polymer Engineers (SPE) Journal in March

1968 (activation energy) to establish a 15.92-year qualified life (22.26 years when accurate

numbers are used). Subsequently, the licensee made use of information in a Curtiss Wright

System 1000 database entry (slope, intercept), which came from the same 1968 science

paper, and determined that the lifetime of polysulfone was 4,103 years. As such, the licensee

concluded that polysulfone is not susceptible to thermal aging. The 1968 science paper

stated that downward extrapolation by 20C or 30C can be done with confidence and

enable one to estimate useful life at end-use operating temperatures. The licensee failed to

apply these limitations when they determined that polysulfone was not susceptible to thermal

aging, indefinitely. In this manner, the licensee failed to meet the requirements of NDCM 3.3

Section 6.2.7, Design Reviews.

Because the determination that the polysulfone terminal blocks are not susceptible to thermal

aging was inappropriate, the established qualified life of these components was 15.92 years

(22.26 years), and because the licensee failed to realize this until it was identified by the

inspectors, the components which were currently installed in the plant - which have been

installed since initial operation of Unit 2 (August 1980) - are beyond their established

qualified life.

Corrective Actions: The licensee entered these three issues into their corrective action

program and determined that the components were functional but non-conforming.

Corrective Action References: CR 1123419, CR 1124362, CR 1124174, and CR 1124632

Performance Assessment:

Performance Deficiency: The licensee failed to verify that design inputs were selected

correctly and that design inputs were correctly used in accordance with Design Control

Manual NDCM 3.3 Section 6.2.7, Design Reviews.

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 objective and adversely affected the cornerstone objective of ensuring

the availability, reliability, and capability of the RCS. Specifically, the licensee failed to

establish a qualified life and replace components (instrument cables; terminal blocks) on that

interval. Keeping a component in service that has exceeded its qualified life reduces the

reliability of that device to perform its safety function when called upon in a design basis

accident.

Significance: The inspectors assessed the significance of the finding using IMC 609,

Appendix A, The Significance Determination Process (SDP) for Findings At-Power.

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 Appendix B Criterion III requires, in part, that design control measures

shall provide for verifying or checking the adequacy of design, such as by the performance of

design reviews, by the use of alternate or simplified calculational methods, or by the

performance of a suitable testing program.

Contrary to the above, since July 7, 1986, the licensee failed to provide design control

measures for verifying or checking the adequacy of design, such as by the performance of

design reviews, by the use of alternate or simplified calculational methods, or by the

performance of a suitable testing program for their 300 V instrument cables and Connectron

terminal blocks.

Enforcement Action: This violation is being treated as an NCV, consistent with Section 2.3.2

of the NRC Enforcement Policy.

Potential 50.9 Violation for Incomplete Information Submittal

71111.21

N

Description: An unresolved item (URI) was identified regarding a potential 10 CFR 50.9

violation for the licensees submittal of incomplete information. Specifically, on June 22, 2000,

the licensee submitted a proposed technical specification change (Virginia Electric and

Power Company North Anna Power Station Units 1 and 2 Proposed Technical Specification

Changes Increased Boron Concentration, ADAMS ML003728735) intended to allow

increasing boron concentration in the RWST, casing cooling tank, safety injection

accumulators, and the spent fuel pool. Section 3.3.3 of the submittal was titled Post-LOCA

Containment Sump and QS pH Analysis, and stated, in part: After consideration of the

proposed revised boron concentrations in the RWST, CCT, and SIAs, the QS and post-LOCA

sump pH analysis limits continue to be met. Specifically, the post-LOCA containment sump

pH is calculated to be between 7.0 and 9.5, and the QS pH is calculated to be between 8.5

8

and 10.5 with at least 95% probability and confidence. Additionally, Section 3.4.2 of the

submittal was titled Equipment Qualification, and stated, in part: Increasing the boron

concentration to 2600 to 2800 ppm in the RWST and CCT and to 2500 to 2800 ppm in the

SIAs will not adversely affect the environmental qualification of equipment in the Equipment

Qualification Master List (EQML). The corrosive agent in chemical spray is primarily NaOH.

Increasing the boron concentration lowers the solution pH making it less corrosive (more

neutral). Therefore, higher boron concentration limits are acceptable, even for those

components qualified at a lower boron concentration. The team identified that the QS system

operates in a manner which results in RWST water, with a pH as low as 4.7, spraying down

containment for at least the first five minutes of a LOCA. The submittal did not include this

information and was therefore incomplete. The team also identified that the licensee had not

evaluated the equipment qualification for this low pH condition for components in containment

Planned Closure Actions: This is an unresolved item pending NRC determination of whether

the issue was material in accordance with the NRC Enforcement Policy (ADAMS

ML19123A129), Section 2.3.11, Inaccurate and Incomplete Information, and the NRC

Enforcement Manual (ADAMS ML 18018B134), Part II, Section 1.5, Material False

Statements and Completeness and Accuracy of Information.

Licensee Actions: The 50.9 aspect of this issue is an administrative issue and poses no

immediate safety or security concerns. The licensee has entered the associated NCV issue

into their Corrective Action Program as CR1123701 and has stated that they will address the

potential 50.9 violation if the NRC determines one exists.

Corrective Action References: CR1123701
