-14, 2018 , at your facility in San Clement e , Californi The inspection was conducted in response to the misalignment of a loaded spent fuel storage canister as it was being downloaded into the storage vault at the San Onofre Nuclear Generating Station (SONGS). Based on the criteria specified in Management Directive 8.3, "NRC Incident Investigation Program," the Nuclear Regulatory Commission (NRC) initiated a Special Inspection in accordance with Inspection Procedure 93812, "Special Inspection." The basis for initiating the Special Inspection and the focus areas for review are detailed in the Special Inspection Charter (Enclosure 3
), dated August 17, 2018 (Agencywide Document Access and Management System (ADAMS)
Accession ML18229A203
). The enclosed report documents the results of the inspectio The inspectors discussed the preliminary inspection findings with Mr. Thomas Palmisano and members of your staff on September 14, 2018 , at the conclusion of the onsite portion of the inspectio A final exit briefing was conducted telephonically with Mr. Palmisano and members of your staff on November 1, 201 Based on the results of the Special Inspection
, two apparent violations were identified and are being considered for escalated enforcement action in accordance with the NRC Enforcement Polic The current Enforcement Policy is included on the NRC Web site at http://www.nrc.gov/about
-nrc/regulatory/enforcement/enforce
-pol.htm The circumstances surrounding these apparent violations, the significance of the associated issues, and the need for corrective action s were discussed with Mr. Palmisano at the conclusion of the onsite inspection and during the final telephonic exit briefin The apparent violations involved the failure to
: (1) ensure important
-to-safety equipment was available to provide redundant drop protection features for a spent fuel canister during downloading operations; and (2) make a timely notification to the NRC Headquarters Operations Center for the August 3, 2018, disabling of important-to-safety equipment
.
D.Bauder2 The NRC is concerned about apparent weaknesses in management oversight of the dry cask storage operation Your staff did not perform adequate direct observational oversight of downloading activities performed by your contractor, ensure adequate training of individuals responsible for performing downloading operations, provide adequate procedures for downloading operations , or ensure that conditions adverse to quality were entered into the corrective action progra The NRC identified that a caus al factor for the misalignment incident involved management weakness in the oversight of dry cask storage operation Before the NRC makes its enforcement decision, we are providing you with an opportunity to
: (1)request a predecisional enforcement conference (PEC) or (2) request alternative disput e resolution (ADR). If a PEC is held, it will be open for public observation and the NRC will iss ue a press release to announce the time and date of the conference.


If you choose to request a PEC, the conference will afford you the opportunity to provide your perspective on these matters and any other information that you believe the NRC should take into consideration before making an enforcement decisio The decision to hold a PEC does not mean that the NRC has determined that a violation has occurred or that enforcement action will be take This conference would be conducted to obtain information to assist the NRC in making an enforcement decisio The topics discussed during the conference may include information to determine whether a violation occurred, information to determine the significance of a violation, information related to the identification of a violation, and information related to any corrective actions taken or planne In presenting your corrective actions, you should be aware that the promptness and comprehensiveness of your actions will be considered in assessing any civil penalty for the apparent violation The guidance in NRC Information Notice 96-28, "Suggested Guidance Relating to Development and Implementation of Corrective Action," may be helpful and can be obtained at the NRC Web site at http://pbadupws.nrc.gov/docs/ML0612/ML061240509.pd In lieu of a PEC, you may also request ADR with the NRC in an attempt to resolve this issu Alternative dispute resolution is a general term encompassing various techniques for resolving conflicts using a neutral third part The technique that the NRC has decided to employ is mediatio Mediation is a voluntary, informal process in which a trained neutral mediator works with parties to help them reach resolutio If the parties agree to use ADR, they select a mutually agreeable neutral mediator who has no stake in the outcome and no power to make decision Mediation gives parties an opportunity to discuss issues, clear up misunderstandings, be creative, find areas of agreement, and reach a final resolution of the issue Additional information concerning the NRC's program can be obtained at http://www.nrc.gov/about
"Evaluate the adequacy of the loading procedure(s) with respect to verification of the movement, centering, lowering, and positioning the canister within the ISFSI vault and procedure adherenc Interviews with personnel involved in the ISFSI loading operations should be conducted to evaluate licensee and contractor communications between crane/VCT operators, rigging and spotting staff, cask loading supervisors, radiation protection staff, and licensee oversight personne Evaluate the adequacy of pre-job briefings that may have taken place prior to fuel loading operations."

-001 On September 10
-14, 2018, the U.S. Nuclear Regulatory Commission performed an announced Special Inspection of the independent spent fuel storage installatio n at the decommissioning San Onofre Nuclear Generating Station in San Clemente, Californi The inspection continued with an in
-office review of training material, licensee analyses, procedures, and other materials gathered during the onsite inspection through November 1 , 2 01 The Southern California Edison Company
, the licensee and owner of San Onofre Nuclear Generating Station
, has an NRC General License for its independent spent fuel installation under Title 10 of the Code of Federal Regulations (10 CFR) Part 7 The scope of the inspection was to evaluate the facts and circumstances involved in the August 3, 2018 , misalignment incident , and review the licensee's follow
-up investigation, causal evaluation, and planned corrective actions
. NRC Special Inspection of San Onofre Nuclear Generating Station Canister Misalignment Incident of August 3, 2018 The licensee's actions that led to disabling the important to safety downloading slings and removal of redundant drop protection features were identified as an apparent violation of Technical Specification 5.2. requirement (Section 3.1.1) The NRC team identified missed opportunities where the licensee could have addressed the potential for a downloading misalignmen For example, o n July 22, 2018, one of the crews experienced misalignment difficulty resulting in a prolonged downloading operatio The licensee did not enter the adverse condition into the corrective action program to determine the cause and develop appropriate corrective action This was identified as a Severity Level IV violation of 10 CFR 72.172 requirements. (Section 3.1.1)
Personnel lacked the proper training, proficiency testing, and certifications to operate important to safety equipmen This was identified as a Severity Level IV violation of 10 CFR 72.192 requirements
. (Section 3.1.2) Dry cask storage procedures did not provide adequate directions for how to determine the downloader slings were slac Slack in the slings was an indicator of a loss-of-loa Further, procedure s did not include qualitative or quantitative means to determin e when a canister had become misaligne These procedure inadequacies were identified as a Severity Level IV violation of 10 CFR 72.150 requirement (Section 3.1.3) No licensee or contractor oversight staff were in direct visual observation of important to safety activities during downloading operations on August 3, 201 Licensee oversight was not a part of communications between the cask loading supervisor, the rigger/spotter, and vertical cask transporter operator during downloading operation (Section 3.1.3) The licensee concluded and the NRC agreed that the minor removal of divider shell coating during downloading operations d id not affect the design functions for shielding, 3 structural, and thermal safety function The licensee's plan to address future inspection of the divider shells in their aging management program is acceptabl (Section 3.1.4)
The licensee failed to make the required 24
-hour NRC notification of the August 3, 2018, incident where important to safety equipment was disabled when required to mitigate the consequences of an accident and no redundant equipment was available to perform the safety functio This failure was identified as an apparent violation of 10 CFR 72.75(d) requirement (Section 3.1.4) The causal evaluations performed by the licensee and its contractor identified apparent and root causes for the August 3, 2018, canister misalignment incident that included inadequate training, inadequate procedures, poor utilization of the corrective action program, and insufficient management oversigh (Section 3.1.5) The licensee's consequence analysis resulting from a hypothetical 25-foot canister drop determined that the canister integrity would be maintaine The NRC will continue to inspect the licensee's consequence analysi (Section 3.1.5) The licensee provide d an analysis to demonstrate that wear on canister 29 during the downloading incident would meet established acceptance criteri The NRC determined that more analysis was required to accept that the canister meets design requirement This charter item will be reviewed during a future NRC inspectio (Section 3.1.6) All associated corrective actions for the August 3, 2018, incident had not been fully developed and implemented by the license The NRC will review the licensee's revised procedures, training plans, equipment modifications, and performance testing (dry runs) of its dry cask storage operations during a future inspection to determine the effectiveness of corrective actions for the inciden (Section 3.1.7)


4 REPORT DETAILS 1 Inspection Scope On September 10
"Determine if the inspection should be elevated to an Augmented Inspection Team (AIT) inspection and promptly notify regional management of any recommendation to escalate the special inspection to an AIT."
-14, 2018, the NRC performed an announced Special Inspection at the San Onofre Nuclear Generating Station (SONGS) in San Clemente, California, which was followed by in-office reviews of additional information provided by the licensee through November 1, 201 The scope of the inspection was to interview personnel associated with the August 3, 2018, misalignment incident to independently evaluate the circumstances of the canister misalignment; identify and review all pertinent records, documents, and procedures related to the licensee's downloading operations; evaluate procedure adequacy and adherence; evaluate the reportability requirements; and to evaluate the root cause analyses and corrective actions to prevent recurrence
. 2 Background 2.1 General Description of Multi-purpose Canister Downloading Operations On November 8, 2018, the NRC conducted a public meeting webinar (NRC's Agencywide Documents Access and Management System (ADAMS) Accession ML18319A139). The presentation provides a summary of a downloading operatio A vertical cask transporter (VCT)
is used for transporting the transfer cask and multi-purpose canister (MPC or canister)
loaded with spent fuel onto the independent spent fuel storage installation (ISFSI) pa Dry cask storage workers manipulate the VCT to align the transfer cask over the ISFSI vertical ventilated module (VVM or vault) in which the canister will be store Once alignment has been achieved and the transfer cask is securely bolted to a mating device, the transfer cask is disconnected from the VC Lifting slings are connected to the top of the canister and the VCT overhead lift bea The VCT lift beam is raised until the load of the canister is supported and no longer resting on the bottom of the transfer cas While the canister is being supported by the lift beam and slings, a drawer on the mating device is opene Once the drawer is open, the VCT operator lower s the lift beam
, which lowers the canister into the storage vaul The VCT can be moved during the download to make fine adjustments for canister alignment within the vaul While the canister is being lowered, it passes through a divider shell assembl Th e divider shell has a shield ring that the canister must pass through as it is being lowered into the vaul When fully downloaded, the canister will be seated on a pedestal in the cavity enclosure container in the vault
. 2.2 August 3, 2018 Canister Misalignment On August 3, 2018, as the loaded canister was being lowered into the vault
, personnel failed to notice that the canister was misaligne The licensee and its contractor continued to lower the VCT lift beam until staff believed that the canister had been fully lowered to the bottom of the vault
. Staff involved in the download failed to recognize the lifting slings were slac A radiation protection technician identified radiation readings that were not consistent with a fully lowered caniste The licensee then identified that 5 the loaded spent fuel canister was resting on a shield ring near the top of the vault, preventing it from being lowered, and that the rigging and lifting slings were slack and no longer bearing the load of the caniste With the slings slack, the lifting equipment was no longer capable of performing its important to safety function of holding and controlling the loaded caniste The canister could have experienced an approximately 17
-18 foot drop into the storage vault if the canister had slipped off the shield ring
. This load drop accident is not a condition analyzed in the dry fuel storage system's Final Safety Analysis Report (FSAR). The licensee restore d the control of the load to the slings and lifting device The estimated time the canister was in an unsupported position was approximately 45 minute The licensee repositioned and lowered the canister into the vaul The licensee subsequently halted all dry fuel storage movement operations in order to fully investigate the incident and develop corrective actions to prevent recurrenc The licensee informed Region IV staff of the misalignment incident on August 6, 2018. Region IV discussed the licensee's plans for evaluation and follow
-up for the incident and the status of fuel loading operation The licensee agreed to suspend fuel loading operations until such time as their senior management was satisfied with their corrective actions, the NRC completed their inspection
, and the NRC determine s that corrective actions are sufficient to prevent a similar occurrenc Region IV chartered a Special Inspection Team to review the incident, any relevant background information, causal and risk assessments conducted by the licensee, and proposed and completed corrective action Special Inspection Charter (IP 93812) 3.1 Inspection Scope Following the notification to NRC Region IV of the August 3, 2018, misalignment incident, the NRC evaluat ed the information provided against the criteria for a reactive inspectio Based on the criteria in Management Directive 8.3 , "NRC Incident Investigation Program
," and Inspection Manual Chapter 0309
, "Reactive Inspection Decision Basis for Reactors," a decision was made to perform a Special Inspectio The Special Inspection Charter is provided in Enclosure 3
. The Special Inspection was conducted onsite from September 10
-14, 2018 , and continued with in
-office review until November 1, 201 The Special Inspection focused on understanding the August 3 , 2018, misalignment inciden The inspection included interviewing personnel involved in the incident, developing a timeline, and assessing the licensee's immediate corrective action The sections below provide inspection details for each of the Special Inspection Charter item . Charter Item 5 Inspection Scope
"Interview personnel associated with the August 3, 2018, misalignment incident to develop a timeline to ensure the licensee's investigation contained all necessary information to identify all contributing factors and develop adequate corrective actions.


" The NRC team interviewed licensee and contractor staff involved or present during the August 3, 2018, misalignment inciden The NRC also reviewed records related to dry cask storage operation Observations and Findings Based on interviews and records review ed, the following timeline was developed:

, the licensee informally contacted NRC Region IV to discuss the August 3, 2018 , misalignment inciden August 7, 2018 NRC Region IV and licensee management agreed that ISFSI operations would cease until the NRC performed an inspection and reviewed the licensee's corrective actions to resume wor September 14, 2018 At 4 pm (ET) the licensee made a formal notification per 10 CFR 72.75(d)(1) to the NRC Headquarters Operations Center regarding the August 3, 2018
, misalignment inciden Violation of 10 CFR 72.172, Corrective Actions Interviews with Williams Industrial Services Group and Sonic Systems (Holtec International subcontractors) employees indicated that of a loss-of-load condition or a canister misalignment issue was experienced during dry run evolutions and known to several dry cask storage worker The Special Inspection team identified a prior canister misalignment issue that occurred on July 22, 2018
, in which downloading operations lasted 90 minutes, instead of the expected 15 minutes for downloading canister 2 This incident was documented in a Production Travele A Production Traveler is a document that the licensee use s to track the performance of dry fuel storage operations by the 8 contractor, Holtec Internationa The Production Travelers were used to track how well the contractor was providing their contracted services to the license The licensee did not enter this condition adverse to quality into its corrective action progra Licensee oversight generally waited for Holtec staff to initiate a field condition report (FCR) before writing a corresponding condition repor In the Production Traveler for canister 2 8 , the 90 minute delay was related to adjustments that were needed for the VCT towers as canister weight started to lower prematurely before the downloading was complet This type of misalignment also occurred during the August 3, 2018 , inciden On July 22, 2018, the downloading crew for canister 28, noted the reduction in the canister weight and corrected the alignment erro The canister was never unsupported by the sling No condition report or FCR was generated by either the licensee or contracto Through interviews with licensee and contractor staff, the NRC determined that between January 30 and August 3, 2018, the downloading activity often involved contact between the canister and other vault components during downloadin The licensee and its contractor did not enter the misalignment and contact events into the corrective action progra Consequently, actions to assess and disposition the exterior conditions of the downloaded canisters and other components within the vault, such as the divider shell assembly, were not performe The licensee is responsible to ensure the important to safety components continue to meet their original design criteria and address any aging management concerns the changes could impac Any deviations, such as scratches or removal of coatings are required to be evaluated to ensure the deviations are not detrimental to the syste Interviews with individuals involved in dry cask loading operations in August 2018, revealed that the difficulty in aligning the canister was not shared with others, nor was it incorporated into procedures or formal training program The VCT operator and the rigger/spotter in charge of downloading operations during the August 3, 2018, incident indicated that they did not know until afterwards that the condition they experienced was something that should have been anticipate CFR 72.172 requires, in part, that, licensees establish measures to ensure that conditions adverse to quality, such as failures, malfunctions, deficiencies, and deviations are promptly identified and correcte Contrary to the above, the licensee failed to establish measures to ensure that conditions adverse to quality, such as failures, malfunctions, deficiencies, and deviations were promptly identified and correcte Specifically:
1. On July 22, 2018, the crew experienced difficulty in aligning canister 2 8 for downloading into the ISFSI vaul However, the licensee failed to enter this deviation in downloading conditions into its corrective action program to determine the cause of the misalignment problem and develop corrective actions to preclude reoccurrenc . From January 30 to August 3, 2018, during canister downloading, contact between the canister and the vault components frequently occurre The licensee failed to enter instances of contact into its corrective action program and perform an assessment to disposition the exterior conditions of the downloaded canisters and vault component The team determined that this violation was more than minor because the failure to implement corrective actions contributed to the misalignment incident of August 3, 201 Additionally, the failure to evaluate and disposition wear marks on a canister, if left uncorrected, could impact the adequacy of the aging management progra The Special Inspection team assessed and dispositioned this violation in accordance with Section 2.2.2 of the NRC Enforcement Polic The team characterized the violation as a Severity Level IV violatio The NRC determined the issuance of a Notice is appropriate because the actions to restore compliance have not been fully developed and implemented, and the actions must be effective prior to beginning fuel handling activitie (VIO 07200041/2018
-001-01, Failure to identify and correct conditions adverse to quality) Apparent Violation of Technical Specification 5.2.c.3, Redundant Lifting Equipment On August 3, 2018, the licensee performed operations involving movement of a loaded spent fuel storage canister into its ISFSI vaul As the loaded spent fuel canister was being lowered into the vault
, licensee and contractor personnel failed to notice that the canister was misaligned and the weight of the canister was not being supported by the redundant important to safety sling s (See Sections 2.1 and 2.2). 10 CFR 72.212(b)(3) requires, in part, that each cask used by the general licensee conforms to the terms, conditions, and specifications of a Certificate of Compliance listed in 10 CFR 72.21 CFR 72.214 includes a list of all the approved spent fuel storage casks that can be utilized under the conditions specified i n a specific Certificate of Compliance
, including Amendment 2 of Certificate of Compliance 072-0104 Certificate of Compliance 072-01040, Amendment 2, Condition 4 , "HEAVY LOADS REQUIREMENTS

-purpose canister transfer operations provided the lifting equipment is designed with redundant drop protection features which prevent uncontrolled lowering of the loa Contrary to the above, on August 3, 2018, the licensee failed to ensure that redundant drop protection features were available to prevent uncontrolled lowering of the loa Specifically, the licensee inadvertently disabled the redundant important to safety downloading slings while lowering canister 29 into the storage vaul During the approximately 45 minute time
-frame, the canister rested on a shield ring unsupported by the redundant downloading slings at approximately 17-18 feet above the fully seated positio This failure to maintain redundant drop protection place d canister 29 in an unanalyzed condition because the postulated drop of a loaded spent fuel canister is not analyzed in the FSA The licensee's failure to ensure the system's designed redundant drop protection features were available to prevent uncontrolled lowering of the loaded canister was identified as an apparent violation of Technical Specification 5.2.c.3
. (AV 07200041/2018
-001-02, Failure to ensure redundant drop protection features are available) Conclusions The licensee failed to adequately implement the corrective action program for ISFSI operation This failure resulted in missed opportunities to resolve misalignment errors during canister downloading operations between January 30 and August 3, 2018, and a violation of 10 CFR 72.172
. On August 3, 2018, the licensee failed to recognize that a misalignment of a canister during downloading operations caused redundant drop protection (slings) to be disabled and an apparent violation of Technical Specification 5.2. .1.2 Charter Item 1 Inspection Scope
"Identify and review all pertinent records, documents, and procedures related to the licensee's downloading operations at the ISFSI pad including but not limited to: worker training and qualifications; rigging equipment qualification, testing, and preventative maintenance; and lifting equipment qualification, testing, and preventative maintenanc Evaluate the adequacy of the above noted procedures, worker training

The team reviewed the qualifications for the dry cask storage workers including the records for the workers involved in the August 3, 2018 , misalignment inciden The team reviewed the inspection and maintenance records for special lifting devices used during dry fuel storage operations and the qualification records for rigging equipmen The team reviewed procedures used during canister downloading operation Observations and Findings The equipment used for dry cask storage operations met applicable inspection requirements specified in the Holtec HI
-STORM UMAX FSA The special lifting devices used to transport the transfer cask and to perform downloading operations were designed and tested according to American National Standards Institute (ANSI) N14.6, "American National Standard for Radioactive Materials
- Special Lifting Devices for Shipping Containers Weighing 10,000 Pounds or More
." The slings used during downloading had a sufficient load rating for the maximum credible load imposed by the caniste The slings were tested according to the safety requirements of American Society of Mechanical Engineers (ASME) B30.9, "Slings." T he purchase specifications, qualifications, and maintenance records for the VCT, downloading slings, canister lift cleats, lift lugs, and lift links were satisfactor Violation of 10 CFR 72.192, Training and Qualifications The NRC team reviewed the qualifications of workers involved in the August 3, 2018, inciden Interviews with the individuals primarily responsible for verifying that the canister was properly downloaded into the ISFSI vault showed that the licensee's training program was inadequate for the positions that are designated as rigger/spotter and VCT operato The VCT operator training program qualifications did not establish adequate required proficiency training exercises for downloading operation The VCT operator on August 3, 2018, had never been tested on or exercised with th e canister simulator during a pre-operational testing, "dry run" downloading operation
. The August 3, 2018, misalignment incident was the first time the VCT operator had actually completed downloading operations as the VCT operato Neither the rigger/spotter nor VCT operator was properly trained in determining a loss-of-load condition during downloading operation The VCT operator stated that he was knowledgeable of the VCT human-machine interface (HMI) screen s and that indications provided a digital reading that could allow the operator to determine if the canister was not supported by the sling However, the VCT operator stated that he did not use the VCT HMI screen to monitor the load of the canister at any time during the August 3, 2018 , downloading operation The VCT operator indicated that he only utilized the HMI screen to determine how evenly the VCT lift beam was descendin From his position on the VCT, the VCT operator could not see the canister downloader sling The only indication of a loss-of-lo ad would come from monitoring the VCT hydraulic b eam pressure digital reading on the VCT HMI screen, which was not performe Since the operator had not performed any proficiency training with the VCT during a dry run downloading operation, the individual was inexperienced with the use of the HMI screen to monitor load los The licensee's training program did not provide a formal process to be qualified for the rigger/spotter position during downloading operation T he rigger/spotter stated that he was not trained on and did not know his roles and responsibilities during the downloading evolution
. The August 3, 2018, misalignment incident was the first time the rigger/spotter had attempted to perform downloading operations as the rigger/spotter in the JL The NRC team's interview with the foreman indicated that the rigger/spotter was selected primarily because of his low accumulated radiation dose
. From interviews with licensee and contractor staff, an experienced RI C was usually the individual placed in the JLG and acted as the rigger/spotter for the downloading operation On August 3, 2018, it was the RIC who eventually entered the JLG after the misalignment and directed the VCT operator to lift the canister with the VCT lift beam to regain the load on the sling The RIC had immediately recognized that the canister was not downloaded into the ISFSI vault when he arrived and saw the condition of the downloader sling The failure to ensure operators are adequately qualified and proficiency tested when operating important to safety equipment and directing critical lift operations is a performance deficienc The licensee's training program that allowed the rigger/spotter and VCT operator to be placed into a situation where their lack of training rendered them 12 incapable of meeting the requirements for the job represent ed a failure of the licensee's training progra CFR 72.
 
192 requires, in part, that the license e establish a program for training, proficiency testing, and certification of ISFSI personnel
. Contrary to the above, from January 30 to August 3, 2018, the licensee failed to establish an adequate program for training, proficiency testing, and certification of all ISFSI personne Specifically
: 1. The training program failed to adequately train and certif y the rigger/spotter position involved in the important to safety downloading operatio . The training program for the vertical cask transporter operator position failed to have adequate proficiency testing on the controls related to the load indicating device and downloading operation The team determined that this violation was more than minor because the licensee's failure to establish an adequate training program contributed to the misalignment incident on August 3, 201 The team assessed and dispositioned this violation in accordance with Section 2.2.2 of the NRC Enforcement Polic The team characterized the violation as a Severity Level IV violatio The NRC determined the issuance of a Notice is appropriate because the actions to restore compliance have not been fully developed and implemented, and the actions must be effective prior to beginning fuel handling activitie (VIO 07200041/2018
-001-03, Failure to establish adequate training program) The team identified that the simulator canister used for training and dry run demonstrations ha d a specified outer diameter that was less than that of the actual spent fuel storage canister s being downloaded into the vaul The simulator canist er provided approximately 0.75 inch more clearance than the actual canisters loaded with spent fue This difference may be acceptable for the dry run activities
; however, the difference was not noted in any of the licensee's training materials for rigger/spotters or the VCT operator This represents a situation of negative training that may have contributed to the August 3, 2018 , misalignment incident
. Conclusions The important to safety lifting equipment and special lifting devices being used for dry cask storage operations met applicable regulatory requirement Personnel lacked the proper training, proficiency testing, and certifications to operat e important to safety equipmen This was identified as a violation of 10 CFR 72.192 requirements

: Holtec International's Root Cause Evaluation The licensee directed Holtec to perform a causal evaluation as a follow-up item in condition report action request 0818-76588 that the licensee initiated following the August 3, 2018, misalignment incident
. The Holtec causal evaluation identified one root cause and five contributing causes
: Root Cause: Holtec Management failed to implement appropriate program improvements or the necessary level of oversight commensurate with the complexity and risks associated with downloading operation Contributing Cause 1: Inadequate content in procedures for recognizing special conditions
. Contributing Cause 2: Design review process did not ensure that unintended consequences of design features were captured
. Contributing Cause 3: Communication protocols with the chain of command established during canister movement were not well defined
. Contributing Cause 4: Holtec had not established a continuous learning environment which promote d the use of internal and external operating experience
. Contributing Cause 5: Holtec Training Program did not fully establish qualification or proficiency requirements for workers performing downloading operation Southern California Edison Company's Apparent Cause Evaluation The licensee initiated an apparent cause evaluation (ACE) to determine how its organization may have contributed to allowing the August 3, 2018, loss-of-load incident to occu The licensee's apparent cause s were related to deficiencies in procedures , training , and in oversight of contractor activitie Apparent Cause 1:
Management fail ed to establish a process to ensure that site dry cask storage procedures were technically accurate
. Apparent Cause 2: Management fail ed to establish licensee and contractor training to support procedure implementation
. Apparent Cause 3: Management fail ed to sufficiently detail contractor Oversight Specialist guidanc Contributing Cause 1: ISFSI project management was not routinely observing dry cask storage operations
. Contributing Cause 2: ISFSI project management was not consistently initiating condition reports for dry cask storage operations that deviated from norma Both the licensee and Holtec causal evaluations reviewed many of the items identified by the NRC tea Those items being
: procedure adequacy; training adequacy; adequacy of the corrective action program; oversight adequacy; and the inconsistent use of operational experience during routine dry cask storage operation The causal evaluations assessed the severity of the canister misalignment inciden The licensee determined that in the event of a canister drop accident from 25 feet into the vault, there was no risk of radioactive exposure to the publi A publicly available version of the licensee's drop analysis summary is available in ADAMS (ADAMS Accession No. ML18330A003). The NRC will continue to review the adequacy of the causal analyses, corrective actions, and potential consequences during a follow-up inspection which is planned to be performed before the resumption of fuel handling activitie Conclusions The apparent and root causes for the August 3, 2018, canister misalignment incident involved inadequate training, inadequate procedures, poor utilization of the corrective action program, and insufficient oversigh .1.6 Charter Item 7 Inspection Scope
"Review the licensee's planned actions that will address the point loading condition that was experienced by the affected caniste If applicable, review the licensee's analysis that demonstrated the canister will continue to perform as designed for continued storage OR review licensee's inspection plan to safely remove or lift the canister from the vault to support inspection of the bottom of the canister to demonstrate the canister did not receive any damage that would inhibit the component from continuing to perform as designed."
 
Observations and Findings The licensee perform ed an evaluation to demonstrate the canister continues to meet the design and performance requirements described in the FSAR
. The Special Inspection team reviewed the licensee's initial assessment of the canister 29 condition after the misalignment inciden The preliminary evaluation provided by the licensee stated that both the canister and vault were not expected to have any physical damage that would exceed the pre
-defined limits used during receipt inspection and manufacturer acceptance testin The NRC requested additional analysis to ensure that the canister meet s design requirements
. Additionally, the licensee is evaluating whether the canister will require increased surveillance frequency for the aging management progra The licensee had not 20 completed the evaluation for NRC review prior to the NRC's inspection exit meeting
. This charter item will be reviewed during a future NRC inspectio Conclusions The licensee has chosen to provide an analysis to demonstrate that the potential damage to canister 29 during the downloading would meet established acceptance criteri The NRC determined that additional analysis was required for the NRC to ensure that the canister meets design requirement This charter item will be reviewed during a future NRC inspectio .1.7 Charter Item 9 Inspection Scope
"As directed by regional management, observe resumption of fuel loading operations to verify that corrective actions were effective in addressing deficiencies that contributed to the inciden This should include evaluation of procedure and/or equipment enhancements; review or observation of training and briefings provided to riggers, crane operators, spotters and observers, supervisors and other personnel involved in fuel loading operations

"Identify and review all pertinent records, documents, and procedures related to the licensee's downloading operations at the ISFSI pad including but not limited to: worker training and qualifications; rigging equipment qualification, testing, and preventative maintenance; and lifting equipment qualification, testing, and preventative maintenanc Evaluate the adequacy of the above noted procedures, worker training, and equipment testing and preparation."

"Evaluate the adequacy of the loading procedure(s) with respect to verification of the movement, centering, lowering, and positioning the canister within the ISFSI vault and procedure adherenc Interviews with personnel involved in the ISFSI loading operations should be conducted to evaluate licensee and contractor communications between crane/VCT operators, rigging and spotting staff, cask loading supervisors, radiation protection staff, and licensee oversight personne Evaluate the adequacy of pre-job briefings that may have taken place prior to fuel loading operations."

"Based on the review of the procedures and interviews of personnel involved with loading operations, evaluate the adequacy of procedure adherence."

"Review and evaluate the licensee's immediate corrective actions taken after the incident for adequacy and notifications to the NRC and safety assessments performed immediately following the inciden Review the licensee's inspection documentation and/or analysis to determine whether the vault's divider shell experienced any damage that would inhibit the component from performing its designed safety function."

"Investigate the licensee's procedures for reportability to the NRC and determine if the licensee made the correct decision regarding notifications made to the NRC for this incident."
