NRC fines Metro Cardiovascular Diagnostics for violations

Content

ACTION:

Notice; issuance.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) issued an Order Imposing Civil Monetary Penalty (Order) to Metro Cardiovascular
Diagnostics. This Order was issued because the licensee was previously issued a Notice of Violation and Proposed Imposition
of Civil Penalty (Notice) in the amount of $36,000 on July 28, 2025. The licensee failed to respond to the Notice or pay the
civil penalty. Despite multiple attempts by the NRC to contact the licensee, no response was received; therefore, the NRC
is imposing the civil penalty through this Order. The NRC staff has determined that the violations occurred as described in
the Notice and that the $36,000 civil penalty proposed for the violations is appropriate and will be imposed. This Order is
effective upon issuance.

DATES:

This order was issued on March 4, 2026.

Attachment—Order Imposing Civil Monetary Penalty

United States of America

Nuclear Regulatory Commission

In the Matter of: Metro Cardiovascular Diagnostics, 030-37587, Florissant, Missouri, 24-32636-01, EAF-RIII-2024-0017

Order Imposing Civil Monetary Penalty

I

Metro Cardiovascular Diagnostics (Licensee) is the holder of NRC Materials License No. 24-32636-01 issued on July 17, 2018,
by the U.S. Nuclear Regulatory Commission (NRC or Commission) pursuant to Part 30 of Title 10 of the Code of Federal Regulations
(10 CFR). The license authorizes the operation of Metro Cardiovascular Diagnostics (facility) in accordance with conditions
specified therein. The facility is located on the Licensee's site in Florissant, Missouri.

II

An investigation of the Licensee's activities was initiated on October 5, 2023, and completed on September 11, 2024. The results
of this investigation indicated that the Licensee had not conducted its activities in full compliance with NRC requirements.
A written Notice of Violation and Proposed Imposition of Civil Penalties (Notice) was served upon the Licensee by letter dated
July 28, 2025. The Notice states the nature of the violations, the provisions of the NRC's requirements that the Licensee
violated, and the amount of the civil penalties proposed for the violations. As of the date of this Order, the Licensee has
neither provided a written response to the Notice nor paid the proposed civil penalty. NRC staff have unsuccessfully attempted
to contact the Licensee multiple times since the issuance of the Notice regarding payment of the proposed civil penalties.

III

Because the Licensee did not respond to the Notice, there are no additional facts, explanation, or other information to consider.
The NRC has determined that the violations occurred as stated and that the penalties proposed for the violations designated
in the Notice should be imposed.

IV

In view of the foregoing and pursuant to Section 234 of the Atomic Energy Act of 1954, as amended (Act), 42 U.S.C. 2282, and
10 CFR 2.205, it is hereby ordered that:

The Licensee shall pay the civil penalties in the amount of $36,000 within 30 days of the date of this Order by submitting
the payment in accordance with NUREG/BR-0254.

In addition, at the time payment is made, the Licensee shall submit a statement indicating when and by what method payment
was made, to the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, One White Flint North, 11555 Rockville
Pike, Rockville, MD 20852-2738.

V

In accordance with 10 CFR 2.202, Metro Cardiovascular Diagnostics must, and any other person adversely affected by this Order
may, submit an answer to this Order within 30 days of its publication in the
Federal Register
. In addition, Metro Cardiovascular Diagnostics and any other person adversely affected by this Order may request a hearing
on this Order within 30 days of its publication in the
Federal Register
. Where good cause is shown, consideration will be given to extending the time to answer or request a hearing. A request for
extension of time must be directed to the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, and include
a statement of good cause for the extension.

All documents filed in NRC adjudicatory proceedings, including documents filed by an interested State, local governmental
body, Federally recognized Indian Tribe, or designated agency thereof that requests to participate under 10 CFR 2.315(c),
must be filed in accordance with 10 CFR 2.302. 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, unless an exemption permitting
an alternative filing method, as further discussed, is granted. Detailed guidance on electronic submissions is located in
the “Guidance for Electronic Submissions to the NRC” (ADAMS Accession No. ML13031A056) and on the NRC's public website (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
their 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 their counsel or representative, already holds an NRC-issued digital
ID certificate). Based upon this information, the Secretary will establish an electronic docket for the 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 (https://www.nrc.gov/site-help/e-submittals/getting-started.html). After a digital ID certificate is obtained and a docket is created, the participant must submit adjudicatory documents
in Portable Document Format (PDF). Guidance on submissions is available on the NRC's public website (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. ET on the due date. Upon receipt of
a transmission, the E-Filing system timestamps the document and sends the submitter an email confirming receipt of the document.
The E-Filing system also distributes an email 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 in order to
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 (https://www.nrc.gov/sitehelp/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., ET,
Monday through Friday, except Federal 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 publicly available
on the NRC's public website (https://adams.nrc.gov/ehd), unless otherwise excluded pursuant to an order of the presiding officer. If you do not have an NRC-issued digital ID certificate
as previously described, click “cancel” when the link requests certificates and you will be automatically directed to the
NRC's electronic hearing docket where you will be able to access any publicly available documents in a J. Siddiqui—8—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.
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 should not include copyrighted materials in their submission.

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

If a hearing is requested by a licensee or 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 Order should be sustained. Pursuant to 10 CFR 2.202(c)(2)(i), Metro Cardiovascular Diagnostics or any other person
adversely affected by this Order, may, in addition to demanding a hearing, at the time the answer is filed or sooner, move
the presiding officer to set aside the immediate effectiveness of the Order on the ground that the Order, including the need
for immediate effectiveness, is not based on adequate evidence but on mere suspicion, unfounded allegations, or error. 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 IV above shall be final 30 days from the date this Order is published in the
Federal Register
without further order or proceedings. If an extension of time for requesting a hearing has been approved, the provisions specified
in Section IV shall be final when the extension expires if a hearing request has not been received. An Answer or a Request for Hearing Shall Not Stay the Immediate Effectiveness of This Order. If payment has not been made by the time specified above, the matter may be referred to the Attorney General, for collection.

For the Nuclear Regulatory Commission.

Dated this 4th day of March 2026.

Bo Pham,

Acting Director, Office of Enforcement.
