Unit 2 began the inspection period at rated thermal power. On March 5, 2021, the unit was down powered to 62 percent rated thermal power for planned maintenance and control rod pattern adjustment. The unit was returned to rated thermal power the following day. The unit remained at or near rated thermal power 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 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.
 
Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the Coronavirus Disease 2019 (COVID-19),resident inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week; conducted plant status activities as described in IMC 2515, Appendix D, Plant Status; observed risk-significant activities; and completed on-site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on-site. The inspections documented below met the objectives and requirements for completion of the IP.

Improper Storage of Nitrogen Bottles in the Reactor Building Cornerstone          Significance                              Cross-Cutting      Report Aspect            Section Mitigating            Green                                      [H.12] - Avoid    71111.15 Systems              NCV 05000341/2021001-01                    Complacency Open/Closed The inspectors identified a finding of very low safety significance (Green) with an associated NCV of TS 5.4.1, "Procedures," for the improper storage of material in the reactor building.
 
Specifically, on multiple occasions the inspectors discovered carts of compressed gas cylinders near safety-related equipment that were not restrained in accordance with plant procedures. Examples included missing chocks, inappropriate standoff distance, storage of equipment not in accordance with existing engineering analyses, and exceeding restraint weight limits.
 
=====Description:=====
On February 12, 2021, the inspectors identified a cart containing 12 nitrogen gas bottles that was not restrained in accordance with plant procedures to reasonably ensure it would not adversely impact nearby safety-related equipment during a seismic event. During operation, the nitrogen is used to periodically recharge the hydraulic control units (HCUs), which helps position or scram the control rods and contain safety-related components. The cart was stored adjacent to an opening leading down to one of the reactor building corner rooms.
 
Several safety-related instruments associated with the RHR system and reactor recirculation system were directly below this opening. This cart was at a location that was not one of two engineering-approved locations for the storage of nitrogen carts. In addition, it was not restrained in accordance with procedure MOP23, "Plant Storage," Revision 6. Specifically, the cart did not have a required wheel chock and was tied off to a handrail that the procedure stated was acceptable for up to 400 pounds when the cart weight was 2,600 pounds. The inspectors notified the licensee, who then moved the cart away from the floor opening.
 
In the following days, the inspectors identified additional nitrogen carts improperly stored adjacent to the HCUs. The carts were missing the required number of chocks and staged too close to the HCUs given their width and height per the requirements contained in MOP23.
 
One of the extra nitrogen carts was subsequently moved and attached to a concrete wall nearby pending removal from the building. However, a few days later the inspectors identified that the cart was missing one of the required restraints for that temporarily approved storage location. The licensee subsequently discovered that one of the two normal staging locations for the HCUs had been previously moved without engineering approval as required by MOP23.
 
Corrective Actions: The permanently approved location that had been moved was analyzed by the licensee for the new location and found to be acceptable. All nitrogen carts located outside of the permanently approved locations were removed from the reactor building. The licensee also performed several walkdowns of the reactor building to eliminate any remaining storage concerns with other equipment. Additionally, the licensee initiated a common-cause analysis to further review the issue.
 
Corrective Action References: CARDs 21-21805, 21-21373, and 21-22200
 
=====Performance Assessment:=====
Performance Deficiency: The inspectors determined that the licensees failure to properly restrain nitrogen carts stored in the reactor building was contrary to licensee procedure MOP23, "Plant Storage," Revision 6, and was a performance deficiency. Examples included missing chocks, inappropriate standoff distance, storage of equipment not in accordance with existing engineering analyses, and exceeding restraint weight limits.
 
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors 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 properly restrain nitrogen carts stored in the reactor building led to reasonable doubt regarding the operability of nearby safety-related components.
 
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors determined the finding was of very low safety significance (Green) based on answering 'no' to all the questions in Section A of Exhibit 2. Specifically, the licensee performed engineering evaluations and reasonably determined the operability/functionality of equipment would be maintained under worst-case seismic conditions.
 
Cross-Cutting Aspect: H.12 - Avoid Complacency: Individuals recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Individuals implement appropriate error reduction tools. Specifically, the licensee made assumptions regarding the acceptability of the storage of nitrogen carts in the reactor building. Further, the licensee did not recognize and plan for the possibility of additional storage issues as evidenced by the additional issues identified by the inspectors after their initial notification of the issue to the licensee.
 
=====Enforcement:=====
Violation: TS 5.4.1, "Procedures," requires, in part, that written procedures shall be established, implemented. and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978.
 
Contrary to the above, since at least February 12 to February 26, 2021, the licensee failed to implement a procedure recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Specifically, Section 9 of Regulatory Guide 1.33 states, in part, that maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. The licensee established procedure MOP23, "Plant Storage," Revision 6, to implement storage and staging requirements of equipment during, in part, maintenance activities that could affect the performance of safety-related equipment. However, the licensee did not implement MOP23 when preplanning and performing maintenance activities involving compressed gas cylinders as evidenced by the following examples:
* The procedure required carts in the reactor building to be chocked and imposed spacing requirements between the carts and safety-related components based on cart dimensions. However, multiple compressed gas cylinder carts in the reactor building were not chocked and staged too close to safety-related components given their dimensions.
* A compressed gas cylinder cart was tied off to a handrail that MOP23 stated was acceptable for up to 400 pounds. However, the cart weight was 2,600 pounds.
* Procedure MOP23 required the storage of compressed gas cylinders in the reactor building to be approved by engineering. However, a compressed gas cylinder cart was stored at a location that had not received prior engineering approval for that purpose.
* Compressed gas cylinders temporarily used in the reactor building were required by MOP23 to be tightly mounted to structures with at least two restraints. However, a temporarily secured compressed gas cylinder cart in the reactor building was mounted to a structure with only one restraint.
 
The start date of the violation was unknown because information was not available to reasonably determine or estimate when the licensee first stored the compressed gas cylinder carts in the reactor building as described above. The inspectors identified the violation on February 12, 2021, and the licensee restored compliance on February 26, 2021.
 
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
 
==EXIT MEETINGS AND DEBRIEFS==
The inspectors verified no proprietary information was retained or documented in this report.
* On April 27, 2021, the inspectors presented the integrated inspection results to Mr. P. Dietrich, Chief Nuclear Officer, and other members of the licensee staff.

Additional Tracking Items

Type Issue Number Title Report Section Status LER 05000341/2020-002-00 LER 2020-002-00 for Fermi 71153 Closed 2, Valid Actuation of Emergency Diesel Generators During Partial Loss of Offsite Power.

PLANT STATUS

Unit 2 began the inspection period at rated thermal power. On March 5, 2021, the unit was down powered to 62 percent rated thermal power for planned maintenance and control rod pattern adjustment. The unit was returned to rated thermal power the following day. The unit remained at or near rated thermal power 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 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.

Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the Coronavirus Disease 2019 (COVID-19),resident inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week; conducted plant status activities as described in IMC 2515, Appendix D, Plant Status; observed risk-significant activities; and completed on-site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on-site. The inspections documented below met the objectives and requirements for completion of the IP.

The inspectors did not identify a violation of NRC requirements.

INSPECTION RESULTS

Improper Storage of Nitrogen Bottles in the Reactor Building Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [H.12] - Avoid 71111.15 Systems NCV 05000341/2021001-01 Complacency Open/Closed The inspectors identified a finding of very low safety significance (Green) with an associated NCV of TS 5.4.1, "Procedures," for the improper storage of material in the reactor building.

Specifically, on multiple occasions the inspectors discovered carts of compressed gas cylinders near safety-related equipment that were not restrained in accordance with plant procedures. Examples included missing chocks, inappropriate standoff distance, storage of equipment not in accordance with existing engineering analyses, and exceeding restraint weight limits.

Description:

On February 12, 2021, the inspectors identified a cart containing 12 nitrogen gas bottles that was not restrained in accordance with plant procedures to reasonably ensure it would not adversely impact nearby safety-related equipment during a seismic event. During operation, the nitrogen is used to periodically recharge the hydraulic control units (HCUs), which helps position or scram the control rods and contain safety-related components. The cart was stored adjacent to an opening leading down to one of the reactor building corner rooms.

Several safety-related instruments associated with the RHR system and reactor recirculation system were directly below this opening. This cart was at a location that was not one of two engineering-approved locations for the storage of nitrogen carts. In addition, it was not restrained in accordance with procedure MOP23, "Plant Storage," Revision 6. Specifically, the cart did not have a required wheel chock and was tied off to a handrail that the procedure stated was acceptable for up to 400 pounds when the cart weight was 2,600 pounds. The inspectors notified the licensee, who then moved the cart away from the floor opening.

In the following days, the inspectors identified additional nitrogen carts improperly stored adjacent to the HCUs. The carts were missing the required number of chocks and staged too close to the HCUs given their width and height per the requirements contained in MOP23.

One of the extra nitrogen carts was subsequently moved and attached to a concrete wall nearby pending removal from the building. However, a few days later the inspectors identified that the cart was missing one of the required restraints for that temporarily approved storage location. The licensee subsequently discovered that one of the two normal staging locations for the HCUs had been previously moved without engineering approval as required by MOP23.

Corrective Actions: The permanently approved location that had been moved was analyzed by the licensee for the new location and found to be acceptable. All nitrogen carts located outside of the permanently approved locations were removed from the reactor building. The licensee also performed several walkdowns of the reactor building to eliminate any remaining storage concerns with other equipment. Additionally, the licensee initiated a common-cause analysis to further review the issue.

Corrective Action References: CARDs 21-21805, 21-21373, and 21-22200

Performance Assessment:

Performance Deficiency: The inspectors determined that the licensees failure to properly restrain nitrogen carts stored in the reactor building was contrary to licensee procedure MOP23, "Plant Storage," Revision 6, and was a performance deficiency. Examples included missing chocks, inappropriate standoff distance, storage of equipment not in accordance with existing engineering analyses, and exceeding restraint weight limits.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors 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 properly restrain nitrogen carts stored in the reactor building led to reasonable doubt regarding the operability of nearby safety-related components.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors determined the finding was of very low safety significance (Green) based on answering 'no' to all the questions in Section A of Exhibit 2. Specifically, the licensee performed engineering evaluations and reasonably determined the operability/functionality of equipment would be maintained under worst-case seismic conditions.

Cross-Cutting Aspect: H.12 - Avoid Complacency: Individuals recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Individuals implement appropriate error reduction tools. Specifically, the licensee made assumptions regarding the acceptability of the storage of nitrogen carts in the reactor building. Further, the licensee did not recognize and plan for the possibility of additional storage issues as evidenced by the additional issues identified by the inspectors after their initial notification of the issue to the licensee.

Enforcement:

Violation: TS 5.4.1, "Procedures," requires, in part, that written procedures shall be established, implemented. and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978.

Contrary to the above, since at least February 12 to February 26, 2021, the licensee failed to implement a procedure recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Specifically, Section 9 of Regulatory Guide 1.33 states, in part, that maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. The licensee established procedure MOP23, "Plant Storage," Revision 6, to implement storage and staging requirements of equipment during, in part, maintenance activities that could affect the performance of safety-related equipment. However, the licensee did not implement MOP23 when preplanning and performing maintenance activities involving compressed gas cylinders as evidenced by the following examples:

  • The procedure required carts in the reactor building to be chocked and imposed spacing requirements between the carts and safety-related components based on cart dimensions. However, multiple compressed gas cylinder carts in the reactor building were not chocked and staged too close to safety-related components given their dimensions.
  • A compressed gas cylinder cart was tied off to a handrail that MOP23 stated was acceptable for up to 400 pounds. However, the cart weight was 2,600 pounds.
  • Procedure MOP23 required the storage of compressed gas cylinders in the reactor building to be approved by engineering. However, a compressed gas cylinder cart was stored at a location that had not received prior engineering approval for that purpose.
  • Compressed gas cylinders temporarily used in the reactor building were required by MOP23 to be tightly mounted to structures with at least two restraints. However, a temporarily secured compressed gas cylinder cart in the reactor building was mounted to a structure with only one restraint.

The start date of the violation was unknown because information was not available to reasonably determine or estimate when the licensee first stored the compressed gas cylinder carts in the reactor building as described above. The inspectors identified the violation on February 12, 2021, and the licensee restored compliance on February 26, 2021.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

  • On April 27, 2021, the inspectors presented the integrated inspection results to Mr. P. Dietrich, Chief Nuclear Officer, and other members of the licensee staff.
