List of Findings and Violations Packing Failure Results in Unit Downpower Cornerstone Significance Cross-Cutting Report Aspect Section Initiating Events Green [H.11] - 71111.19 FIN 05000397/2019002-01 Challenge the Open/Closed Unknown The inspectors reviewed a self-revealed, Green finding for the licensees failure to follow station procedure, Plant Procedures Manual (PPM) 10.2.79, Valve Packing and Live Loading, Revision 17, Step 4.13, for maintaining proper clearances of Chesterton packing.
Specifically, the station failed to maintain proper clearances of Chesterton packing on the condensate booster pump 2C discharge check valve. This resulted in a packing leak and subsequent packing failure, requiring a unit downpower to 65 percent to repair the valve.
Failure to Request Exemption from DOT Packaging Requirements Cornerstone Significance Cross-Cutting Report Aspect Section Not Applicable NCV 05000397/2019012-01 Not Applicable 71152 Open/Closed The inspectors identified a Severity Level IV, non-cited violation (NCV) of 10 CFR 71.5(b)when the licensee failed to request an exemption from the Department of Transportation (DOT) packaging requirements prior to transporting greater than Type A quantities of radioactive material in a Type A packaging.
Additional Tracking Items None.
PLANT STATUS
The reactor unit began the inspection period at rated thermal power. On May 11, 2019, the plant was shut down for a planned refueling outage. On June 17, 2019, the reactor was made critical following completion of the refueling outage. On June 21, 2019, operations personnel synchronized the main generator with the grid and began power ascension. On June 23, 2019, the plant reached 100 percent power, where it remained for the remainder of the inspection period.
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 performed plant status activities described in IMC 2515 Appendix D, Plant Status and conducted routine reviews using IP 71152, Problem Identification and Resolution.

- (2) transport of radioactive waste shipments 13-07 and 14-07 to disposal facility on May 10, 2019
Semiannual Trend Review (IP Section 02.02) (1 Sample)
The inspectors reviewed the licensees corrective action program for potential adverse trends in foreign material exclusion practices that might be indicative of a more significant safety issue and documented one observation on June 23,
INSPECTION RESULTS
Observation: Foreign Material Exclusion Practices 71152 The inspectors performed an in-depth review of the licensee's evaluation and corrective actions related to a potential negative trend in foreign material exclusion practices. From January 1, 2019, to the beginning of Refueling Outage R24 on May 11, 2019, the licensee initiated seven Action Requests (ARs) related to the foreign material exclusion program: one documenting a foreign material evaluation, one initiating a self assessment of the foreign material exclusion program, one initiating an evaluation of several training programs including the foreign material exclusion program, and four documenting foreign material identified in the plant. Conversely, during Refueling Outage R24, from May 11, 2019, through June 22, 2019, the licensee initiated 36 ARs related to the foreign material exclusion program: 2 documenting a foreign material evaluation, 1 documenting a potential foreign material concern, and 33 documenting foreign material identified in the plant. The inspectors noted that approximately half of the 33 outage ARs documenting foreign material in the plant were a result of ongoing work.
The inspectors assessed the licensee's problem identification threshold, evaluations, and corrective actions related to these ARs. The inspectors identified that the licensee had not initiated an AR to document the trend or the increase in foreign material ARs. The inspectors also noted that the licensee's use of foreign material trend codes was inconsistently applied to ARs documenting foreign material found in the plant. Of the 37 ARs reviewed that documented foreign material in the plant, 12 ARs did not have a foreign material trend code assigned. The licensee initiated AR 396578 to document the concern. The inspectors determined that for each AR that documented foreign material in the plant the licensee either retrieved the foreign material before the end of the outage or adequately evaluated leaving the foreign material in the plant for later retrieval.
Packing Failure Results in Unit Downpower Cornerstone Significance Cross-Cutting Report Aspect Section Initiating Events Green [H.11] - 71111.19 FIN 05000397/2019002-01 Challenge the Open/Closed Unknown The inspectors reviewed a self-revealed, Green finding for the licensees failure to follow station procedure, Plant Procedures Manual (PPM) 10.2.79, Valve Packing and Live Loading, Revision 17, step 4.13, for maintaining proper clearances of Chesterton packing.
Specifically, the station failed to maintain proper clearances of Chesterton packing on the condensate booster pump 2C discharge check valve. This resulted in a packing leak and subsequent packing failure, requiring a unit downpower to 65 percent to repair the valve.
Description:
On January 21, 2019, the condensate booster pump 2C discharge check valve experienced a packing failure. The failure resulted in hot water spraying several feet across the personnel walkway and onto the adjacent, running condensate booster pumps. The licensee determined the leakage spraying from the valve posed a hazard to licensee personnel and the adjacent operating condensate booster pumps, and reduced reactor power to 65 percent power to replace the valve packing.
The condensate booster pump 2C discharge check valve is a 20-inch Walworth check valve that utilizes Chesterton packing. Step 4.13 of PPM 10.2.79, Valve Packing and Live Loading, provides guidance for maintaining proper clearances and finishes of Chesterton packing. The required clearance between the stuffing box inner diameter and the packing outer diameter is -0.003 to +0.015 inches. If the condition of material does not meet the guidance, the step also directs licensee personnel to initiate and resolve an Action Request (AR) prior to repacking the valve.
The licensee last repacked the valve per Work Order 02072877 on May 26, 2017, during Refueling Outage R23. The valve packing data sheet associated with the work package stated that the stuffing box inner diameter was 1.875 inches and listed packing appropriately sized for that diameter. During the repack, licensee personnel identified and wrote in the work package that the stuffing box inner diameter was actually 1.906 inches; however, contrary to step 4.13 of PPM 10.2.79, no AR was written to solve the discrepancy. Therefore, the installed packing had a clearance between the stuffing box inner diameter and the packing outer diameter of +0.031 inches which did not meet the requirements of step 4.13 of PPM 10.2.79.
The valve packing leakage was originally identified on November 6, 2017 and documented as approximately 45 drops per minute in AR 373494. The licensee installed a catch underneath the valve to collect the leakage and closed the AR. The inspectors noted the licensee had a missed opportunity to repair the packing leak during Forced Outage FO-18-01 in May 2018; however, no work was performed due to the low leakage collected by the installed catch at the time. This allowed the packing to further degrade and subsequently fail on January 21, 2019.
Corrective Actions: The licensee repaired the condensate booster pump 2C discharge check valve, performed an extent of condition investigation, repaired the condensate booster pump 2A and 2B discharge check valves packing, and briefed all mechanics on the importance of following procedures.
Corrective Action References: ARs 373494, 389079, and 3894892
Performance Assessment:
Performance Deficiency: The failure to follow station procedures 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 Initiating Events cornerstone. The failure to follow station procedures adversely affected the cornerstone objective to limit the frequency of those events and operations that upset plant stability and challenge critical safety functions, during shutdown as well as power operations. Specifically, the station failed to maintain proper clearances of Chesterton packing on the condensate booster pump 2C discharge check valve. This resulted in a packing leak and subsequent packing failure, requiring a unit downpower to 65 percent to repair the valve.
Significance: The inspectors assessed the significance of the finding using Appendix A, Significance Determination of Reactor Inspection Findings for At - Power Situations. Using the questions in Exhibit 1, Initiating Events Screening Questions, the inspectors determined the finding was of very low safety significance (Green) because the finding did not cause a reactor trip and the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition.
Cross-Cutting Aspect: H.11 - Challenge the Unknown: Individuals stop when faced with uncertain conditions. Risks are evaluated and managed before proceeding. Specifically, when working on the valve packing, the licensee documented valve packing dimensional discrepancies in the work package but did not stop work to resolve the discrepancies. This caused packing to be installed that was outside of allowed tolerances and resulted in the packing leak and subsequent packing failure.
Enforcement:
Inspectors did not identify a violation of regulatory requirements associated with this finding.
Failure to Request Exemption from DOT Packaging Requirements Cornerstone Severity Cross-Cutting Report Aspect Section Not Severity Level IV Not 71152 Applicable NCV 05000397/2019012-01 Applicable Open/Closed The inspectors identified a Severity Level IV, non-cited violation (NCV) of 10 CFR 71.5(b)when the licensee failed to request an exemption from the Department of Transportation (DOT) packaging requirements prior to transporting greater than Type A quantities of radioactive material in a Type A packaging.
Description:
On March 26, 2013, and April 22, 2014, the licensee shipped packages of radioactive material from Columbia Generating Station to US Ecology in Richland, WA. In each of the shipments, Numbers (Nos.) 13-07 and 14-07, the quantity (activity) of radioactive material exceeded the allowed activity for the type of shipping cask used. Specifically, both shipments of reactor water cleanup resins contained greater than the A2 quantity of normal form radioactive material in a Type A package. However, 49 CFR 173.431 specifies that a Type A package may not contain a quantity greater than A2.
The licensee used an Energy Solutions Model 10-142A cask for these shipments. This cask had previously been certified as Type B (Certification of Compliance No. 9208), but the certification expired October 1, 2008. The inspectors reviewed Certificate of Compliance No. 9208 for the cask and the Safety Evaluation Report. The Safety Evaluation Report stated, The Model No.10-142 package was fabricated prior to the 1983 edition of 10 CFR Part 71 and is designation [sic] with B() to identify the timeframe when the application was approved. Regulations in 10 CFR Part 71 will expire packages with the B() designation on October 1, 2008 The inspectors also reviewed Information Notice 84-14, Highlights of Recent Transport Regulatory Revisions by DOT and NRC. It was determined that the 1983 changes related to Type B packages in 10 CFR 71 were somewhat administrative in nature, in that the previous rules made no distinction in Type B standards as related to multilateral versus unilateral approval for purposes of international shipments. However, there were also changes to design specification and accident test requirements to which the cask had not been subject.
The licensee recognized that the cask was no longer certified as Type B and had modified their procedures accordingly prior to use of the cask for the 2013 and 2014 shipments. The inspectors noted that PPM 11.2.23.43, Use of the Model 10-142 Transportation Cask, (Revision 000, dated 2/11/13 and Revision 001 dated 4/14/14), stated in Section 2.0, Discussion, "The 10-142 shielded transportation caskwas formerly licensed to transport Type B quantities of radioactive material but is no longer licensed to transport this type of material. A road closure is required to transport Type B quantities of radioactive materials in the 10-142 transportation cask."
The inspectors also noted that the licensee provided the following information in Box 11 of the waste manifest (proper shipping name and UN ID number) for shipments Nos. 13-07 and 14-07:
Radioactive Material - Not Subject to DOT Regulations, Not Entering Public Roadway, RQ - RWCU Resins, 1 High Integrity Container. FOR INFORMATION USE ONLY:
UN2916, RQ, Radioactive Material, Type B(U) Fissile Excepted.
The licensee considered the Hanford reservation to be a contiguous facility boundary, since both Columbia and US Ecology lease the land they are sited on from the Department of Energy (DOE); consequently, the licensee assumed 49 CFR 171.1(d)(4) applied.
Specifically, 49 CFR 171.1(d)(4) states, in part, that motor vehicle movements of a hazardous material exclusively within a contiguous facility boundary where public access is restricted is not subject to the requirements of the Hazardous Material Regulations.
The inspectors noted that DOT provided Hanford DOE with an interpretation of public access with respect to 49 CFR 171.1 (d)(4) dated April 22, 2014. Specifically, the DOT considered the roads south of the Wye Security Checkpoint on the Hanford reservation as in commerce and accessible to the public. Roads north of the checkpoint are out of commerce and not accessible to the public. The burial site is located north of the Wye security checkpoint, while Columbia station is located south of the Wye Security Checkpoint.
Regardless, the NRC requirement in 10 CFR 71.5(b) renders the determination of whether the Hanford reservation is considered a contiguous facility moot for shipments of licensed radioactive material. Specifically, 10 CFR 71.5(b) states, in part, If DOT regulations are not applicable to a shipment of licensed material, the licensee shall conform to the standards and requirements of the DOT specified in paragraph (a)of this section to the same extent as if the shipment or transportation were subject to DOT regulations. A request for modification, waiver, or exemption from those requirements must be made to the director, Office of Nuclear Material Safety and Safeguards (NMSS).
The inspectors noted that the robust design of the cask resulted in external dose rates on the packages that were low, relative to the activity contained within, posing less risk to the public than other Type A packages. Specifically, the maximum contact dose rate on each shielded cask was 25 mrem/hr (No. 13-07) and 50 mrem/hr (No. 14-07). Additionally, during these shipments, public access to the road between Columbia and US Ecology was controlled by DOE security. The licensee had discussions with the State of Washington and Hanford DOE to coordinate the details of the shipments, further ensuring the public would be adequately protected.
The inspectors discussed the information related to these shipments with staff from NRC NMSS, the organization responsible for approving modifications, waivers, and exemptions to DOT requirements per 10 CFR 71.5(b). After review of the shipping paperwork, NMSS staff concluded that had the licensee submitted a request for an exemption the exemption could have been granted, provided that the licensee demonstrated that the shipment using a Type A packaging posed no more risk than if the material were shipped using a Type B packaging. This determination was supported by the degree of control of public access during the time of shipment and the fact that the packaging used during the shipment was previously certified as a Type B packaging and thus was more robust than a typical Type A packaging. Specifically, during these shipments public access to the road between Columbia and US Ecology was controlled by DOE security. Additionally, the licensee had discussions with the State of Washington and DOE (Hanford) to coordinate the details of the shipments, further ensuring the public would be adequately protected.
Corrective Actions: The licensee reviewed procedures and determined that the current procedures neither allowed nor provided direction for shipping radioactive material over public roadways that had been closed. Further, the licensee also determined that no radioactive shipments have been made over closed public roadways since the 2014 shipment. Lastly, they determined that procedure SWP-RMP-04, Radioactive Waste Management Program, effective August 15, 2018, explicitly calls out the requirement in 10 CFR 71.5(b), i.e., if DOT regulations are not applicable to a shipment of licensed material, they must conform with the standards and requirements of DOT to the same extent as if the shipment were subject to DOT regulations.
Corrective Action References: AR 00391202
Performance Assessment:
The inspectors determined this deviation was associated with a minor performance deficiency.
Enforcement:
The ROPs significance determination process does not specifically consider the regulatory process impact in its assessment of licensee performance. Therefore, it is necessary to address this violation which impedes the NRCs ability to regulate using traditional enforcement to adequately deter non-compliance.
Severity: The inspectors determined that, based on the relatively low safety significance of these two shipments, as supported by the facts the roads were closed, the shipment was made in accordance with all other DOT regulations, and NMSS would have approved the shipments with reasonable restrictions, the failure to request an exemption was primarily administrative in nature and properly characterized as a Severity Level IV violation. This is similar to the examples of Severity Level IV violations in Sections 6.1.d and 6.8.d of the Enforcement Policy.
Violation: 10 CFR 71.5(a) requires, in part, each licensee who transports licensed material outside the site of usage, as specified in the NRC license, shall comply with the applicable requirements of the DOT regulations in 49 CFR parts 107, 171 through 180, and 390 through 397.
49 CFR 171.1(d), Functions not subject to the requirements of the [Hazardous Materials Regulations], paragraph
- (4) states, in part, motor vehicle movements of a hazardous material exclusively within a contiguous facility boundary where public access is restricted, except to the extent that the movement is on or crosses a public road, unless access to the public road is restricted by signals, lights, gates, or similar controls. 10 CFR 71.5(b) requires, in part, if DOT regulations are not applicable to a shipment of licensed material, the licensee shall conform to the standards and requirements of the DOT specified in paragraph
- (a) of this section to the same extent as if the shipment or transportation were subject to DOT regulations.
49 CFR 173.431(a) requires, in part, that a Type A package may not contain a quantity of radioactive materials greater than A2 for normal form radioactive material.
10 CFR 71.5(b) requires, in part, a request for modification, waiver, or exemption from those requirements be made to the Director, Office of Nuclear Material Safety and Safeguards, U.S.
Nuclear Regulatory Commission, Washington, DC 20555-0001.
Contrary to the above, on March 16, 2013, and April 22, 2014, the licensee failed to request a modification, waiver, or exemption from those requirements be made to the director, Office of Nuclear Material Safety and Safeguards, U.S. Nuclear Regulatory Commission, Washington, DC. Specifically, on those dates the licensee transported greater than an A2 quantity of normal form material in a Type A cask instead of the required Type B cask without requesting an exemption from 49 CFR 173.431(a) because they believed that because both Columbia and US Ecology were exclusively within the contiguous facility boundary of DOEs Hanford Reservation and access to the public road was restricted, that they were not subject to DOT requirements.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
