CONFIRMATORY ORDER
EFFECTIVE UPON ISSUANCE
I
Mistras Group, LLC. (Mistras) performs activities such as testing of heavy lifting
equipment at nuclear power plants licensed by the U.S. Nuclear Regulatory Commission
(NRC or Commission). Mistras, as specified in purchase orders and contracts with NRC
licensees, is required to implement Appendix B, “Quality Assurance Criteria for Nuclear
Power Plants and Fuel Reprocessing Plants,” of Part 50, “Domestic Licensing of
Production and Utilization Facilities,” to Title 10 of the Code of Federal Regulations (10
CFR). Mistras’ non-destructive testing (NDT) service includes usage of an Acoustic
Emission (AE) Data Acquisition System to examine the structural integrity of cranes
used for lifting components such as reactor vessel heads and reactor vessel internals at
many NRC licensee sites.
This Confirmatory Order (CO) is the result of an agreement reached during an
Alternative Dispute Resolution (ADR) mediation session conducted on March 21, 2024,
in Rockville, Maryland, to address one apparent violation.

II

On October 22, 2021, the NRC’s Office of Investigations (OI) opened an investigation
(OI Case No. 1-2022-003) at Mistras’ Trainer, Pennsylvania facility. The investigation, which
was completed on October 19, 2022, and supplemented on May 9, 2023, evaluated whether a
former Director of Advanced Services and a former NDT engineer engaged in deliberate
misconduct by falsifying certificates of calibration for AE equipment that was used to perform
inspections of heavy lifting equipment for safety-related components at nuclear power plants.
Based on the conclusions of the investigation, the NRC’s Office of Nuclear Reactor
Regulation, Division of Reactor Oversight, Quality Assurance Vendor Inspection Branch, issued
an apparent violation that was documented in an NRC letter, dated December 7, 2023
(Agencywide Documents Access and Management System (ADAMS) Accession No.
ML23340A106).
The apparent violation of 10 CFR 50.5, “Deliberate misconduct,” stated that from
approximately 2011 until 2021, Mistras (a contractor) knowingly provided services related to
licensees’ activities in 10 CFR Part 50 and deliberately submitted to licensees information that
the person submitting the information knew to be incomplete or inaccurate in some respect
material to the NRC. Specifically, Mistras maintained falsified records documenting the
calibration of test equipment used at nuclear power plants. On multiple occasions, two Mistras
employees created falsified documents to conceal Mistras’ failure to calibrate the AE Data
Acquisition Systems on an annual basis, as specified by the equipment manufacturer. These
falsified documents, including certificates of calibration, were submitted to NRC licensees as
part of AE test reports on multiple occasions between approximately 2011 and 2021.

Additionally, the apparent violation stated that the Mistras AE test reports provided by
Mistras to licensees (which included the falsified certificates of calibration) are material to the
NRC. The test reports concerned AE systems that were used in activities affecting quality (e.g.,
AE systems were used by NRC licensees to examine the structural integrity of cranes used for
lifting components such as reactor vessel heads and reactor vessel internals), and the test
reports are quality assurance records in accordance with Appendix B, Criterion XVII, “Quality
Assurance Records,” to 10 CFR Part 50, which provide evidence that licensees are in
compliance with NRC regulations.
When issuing the apparent violation, the NRC provided Mistras an opportunity to attend
a pre-decisional enforcement conference or participate in an ADR mediation session to resolve
this concern. In response, Mistras requested the use of the NRC’s ADR process. On March 21,
2024, the NRC and Mistras conducted an ADR session mediated by a professional mediator,
arranged through Cornell University’s Scheinman Institute on Conflict Resolution. The ADR
process is one in which a neutral mediator, with no decision-making authority, assists the
parties in reaching an agreement to resolve any differences regarding the dispute. This
Confirmatory Order is issued pursuant to the agreement reached during the ADR process.

III

NRC and Mistras reached a preliminary settlement agreement during a full-day
mediation session that was conducted on March 21, 2024. The elements of the agreement
include the following:
1. In recognition of the prompt and corrective actions taken in response to the apparent
violation, as documented in this CO and discussed at the ADR, Mistras is not required to
provide a written response in accordance with 10 CFR 2.201. Corrective actions
completed by Mistras prior to the mediation session include, but are not limited to, the
following:

a. Individuals responsible for the fraudulent records had their employment
terminated.

b. AE instruments were properly calibrated by Physical Acoustics, the
manufacturer of the equipment.

c. Developed a web‐based training course for all employees, which included an
introduction by the company's Chief Executive Officer, to speak about the
importance of promoting a culture of ethics, and how any deliberate misconduct
has consequences, including loss of employment and imprisonment.

d. Local and Corporate Quality Departments reviewed procedures, records, and
equipment.
e. AE procedures and forms were adopted into the Corporate Document Center,
as formal quality assurance records.

f.

AE test equipment was added to the measuring and test equipment (M&TE)
recall system.

g. AE program procedures and work instructions were revised to clarify the
calibration verification instructions and to identify future calibration
requirements.

h. Notification letters were written and distributed to notify applicable nuclear
power plants of the nonconformance associated with their equipment.

i.

An interim report and a final 10 CFR Part 21 report were submitted to the NRC.

j.

Mistras developed or revised the following procedures:
i. Revised procedure 100-QC-006, “Contract Review & Project Planning”
to ensure that “Nuclear Projects” are submitted to the Nuclear Projects
Division for review.
ii. Revised procedure 100-QC-007, “Project Execution.”
iii. Developed procedure 100-QC-007.1, “Nuclear Projects” which defined
the Nuclear Projects Division.
iv. Revised procedure 100-QC-014 “Internal Audits” to require additional
oversight of Nuclear Projects by requiring an annual audit by an outside,
independent Lead Auditor.
v. Planned revision of 100-QC-017 “Control of Nonconforming Items.”
vi. Revised procedure 100-QC-017.1, “Reporting of Defects and
Noncompliance in Accordance with 10 CFR Part 21 and 10 CFR
50.55(e),” Revision 6, dated October 9, 2023, which incorporates
appropriate evaluation criteria consistent with guidance provided in
Nuclear Energy Institute (NEI) 14-09, “Guidelines for Implementation of

10 CFR Part 21 Reporting of Defects and Noncompliance.”
2. Mistras agreed upon future actions in the following areas (see Section V for details):
a. Safety Culture and Safety Conscious Work Environment
b. Quality Assurance Program
c. Audit
d. Quality Assurance Program Training for Employees Involved in Nuclear SafetyRelated Activities

3. The NRC considers the corrective actions and commitments delineated above to
be appropriately prompt and comprehensive to address the causes which resulted
in the apparent violation identified in NRC’s December 7, 2023, letter.

4. In consideration of the commitments delineated above and described in Section V
below, the NRC agrees not to assess a civil penalty and refrain from issuing a
notice of violation for all matters discussed in the NRC’s choice letter dated
December 7, 2023 (EA-23-105).

5. The NRC and Mistras agree that the above elements will be incorporated into a
Confirmatory Order which will also describe the apparent violation.

6. The Confirmatory Order is an escalated enforcement action in accordance with the NRC
Enforcement Policy.

7. In the event of the sale of Mistras Services division, which services commercial nuclear
facilities, to another entity, the terms and conditions set forth hereunder shall continue to
apply to the new entity and accordingly survive any transfer of ownership.

8. The Director, Office of Enforcement, may, in writing, relax, rescind, or withdraw any of
the above conditions upon demonstration by Mistras or its successors of good cause.

Based on the completed (and planned) actions described above, and the commitments
described in Section V below, the NRC agrees to not pursue any further enforcement action
based on the apparent violation identified in NRC’s December 7, 2023, letter (see Section I).

On May 15, 2024, Mistras consented to issuing this Confirmatory Order with the
commitments, as described in Section V below. Mistras further agreed that this Confirmatory
Order is to be effective upon issuance, the agreement memorialized in this Confirmatory Order
settles the matter between the parties, and Mistras has waived its right to a hearing.

IV

I find that the actions completed or planned by Mistras, as described in Section III above,
combined with the commitments as set forth in Section V, are acceptable and necessary, and
conclude that public health and safety are reasonably assured with these completed actions and
commitments. In view of the foregoing, I have determined that public health and safety require
that Mistras’ commitments be confirmed by this Order. Based on the above and Mistras’
consent, this Confirmatory Order is effective upon issuance.
V

VI

In accordance with 10 CFR 2.202 and 10 CFR 2.309, any person adversely affected by
this CO, other than Mistras, may request a hearing within 30 calendar days of the date of
issuance of this CO. Where good cause is shown, consideration will be given to extending the
time to request a hearing. A request for extension of time must be made in writing to the
Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555,
and include a statement of good cause for the extension.

All documents filed in NRC adjudicatory proceedings, including a request for hearing and
petition for leave to intervene (petition), any motion or other document filed in the proceeding
prior to the submission of a petition, and documents filed by interested governmental entities
that request to participate under 10 CFR 2.315(c), must be filed in accordance with the NRC’s
E-Filing rule (72 FR 49139; August 28, 2007, as amended at 77 FR 46562; August 3, 2012).
The E-Filing process requires participants to submit and serve all adjudicatory documents over
the internet, or in some cases to mail copies on electronic storage media. Detailed guidance on
making electronic submissions may be found in the Guidance for Electronic Submissions to the
NRC and on the NRC Web site at https://www.nrc.gov/site-help/e-submittals.html.
Participants may not submit paper copies of their filings unless they seek an exemption in
accordance with the procedures described below.

To comply with the procedural requirements of E-Filing, at least 10 days prior to the filing
deadline, the participant should contact the Office of the Secretary by email at
hearing.docket@nrc.gov, or by telephone at 301-415-1677, to (1) request a digital identification
(ID) certificate, which allows the participant (or its counsel or representative) to digitally sign
submissions and access the E-Filing system for any proceeding in which it is participating; and
(2) advise the Secretary that the participant will be submitting a petition or other adjudicatory
document (even in instances in which the participant, or its counsel or representative, already
holds an NRC-issued digital ID certificate). Based upon this information, the Secretary will
establish an electronic docket for the hearing in this proceeding if the Secretary has not already
established an electronic docket.

Information about applying for a digital ID certificate is available on the NRC’s public
website at https://www.nrc.gov/site-help/e-submittals/getting-started.html. Once a participant
has obtained a digital ID certificate and a docket has been created, the participant can then
submit adjudicatory documents. Submissions must be in Portable Document Format (PDF).
Additional guidance on PDF submissions is available on the NRC’s public website at
https://www.nrc.gov/site-help/electronic-sub-ref-mat.html. A filing is considered complete at the
time the document is submitted through the NRC’s E-Filing system. To be timely, an electronic
filing must be submitted to the E-Filing system no later than 11:59 p.m. Eastern Time on the due
date. Upon receipt of a transmission, the E-Filing system time-stamps the document and sends
the submitter an email notice confirming receipt of the document. The E-Filing system also
distributes an email notice that provides access to the document to the NRC’s Office of the
General Counsel and any others who have advised the Office of the Secretary that they wish to
participate in the proceeding, so that the filer need not serve the document on those participants

separately. Therefore, applicants and other participants (or their counsel or representative)
must apply for and receive a digital ID certificate before adjudicatory documents are filed so that
they can obtain access to the documents via the E-Filing system.

A person filing electronically using the NRC’s adjudicatory E-Filing system may seek
assistance by contacting the NRC’s Electronic Filing Help Desk through the “Contact Us” link
located on the NRC’s public website at https://www.nrc.gov/site-help/e-submittals.html, by email
to MSHD.Resource@nrc.gov, or by a toll-free call at 1- 866-672-7640. The NRC Electronic
Filing Help Desk is available between 9 a.m. and 6 p.m., Eastern Time, Monday through Friday,
excluding Federal government holidays.

Participants who believe that they have good cause for not submitting documents
electronically must file an exemption request, in accordance with 10 CFR 2.302(g), with their
initial paper filing stating why there is good cause for not filing electronically and requesting
authorization to continue to submit documents in paper format. Such filings must be submitted
by (1) first class mail addressed to the Office of the Secretary of the Commission, U.S. Nuclear
Regulatory Commission, Washington, DC 20555-0001, Attention: Rulemaking and
Adjudications Staff; or (2) courier, express mail, or expedited delivery service to the Office of the
Secretary, 11555 Rockville Pike, Rockville, Maryland 20852, Attention: Rulemaking and
Adjudications Staff. Participants filing adjudicatory documents in this manner are responsible for
serving the document on all other participants. Filing is considered complete by first-class mail
as of the time of deposit in the mail, or by courier, express mail, or expedited delivery service
upon depositing the document with the provider of the service. A presiding officer, having

granted an exemption request from using E-Filing, may require a participant or party to use EFiling if the presiding officer subsequently determines that the reason for granting the exemption
from use of E-Filing no longer exists.

Documents submitted in adjudicatory proceedings will appear in the NRC’s electronic
hearing docket which is available to the public at https://adams.nrc.gov/ehd, unless excluded
pursuant to an order of the Commission or the presiding officer. If you do not have an NRCissued digital ID certificate as described above, click “cancel” when the link requests certificates
and you will be automatically directed to the NRC’s electronic hearing dockets where you will be
able to access any publicly available documents in a particular hearing docket. Participants are
requested not to include personal privacy information, such as social security numbers, home
addresses, or personal phone numbers in their filings, unless an NRC regulation or other law
requires submission of such information. For example, in some instances, individuals provide
home addresses in order to demonstrate proximity to a facility or site. With respect to
copyrighted works, except for limited excerpts that serve the purpose of the adjudicatory filings
and would constitute a Fair Use application, participants are requested not to include
copyrighted materials in their submission.

The Commission will issue a notice or order granting or denying a petition, designating
the issues for any hearing that will be held, and designating the Presiding Officer. A notice
granting a hearing will be published in the Federal Register and served on the parties to the
hearing.

If a person (other than Mistras) requests a hearing, that person shall set forth with
particularity the manner in which his interest is adversely affected by this CO and shall address
the criteria set forth in 10 CFR 2.309(d) and (f). If a hearing is requested by a person whose

interest is adversely affected, the Commission will issue an order designating the time and place
of any hearings. If a hearing is held, the issue to be considered at such hearing shall be
whether this CO should be sustained.

In the absence of any request for hearing, or written approval of an extension of time in which to
request a hearing, the provisions specified in Section V above shall be final 30 days from the
date of this CO without further order or proceedings. If an extension of time for requesting a
hearing has been approved, the provisions specified in Section V shall be final when the
extension expires if a hearing request has not been received.
