Announcements for Suppliers

The following announcements are provided when it becomes necessary to share applicable information regarding road closures, fraud information, the DPO process, and other pertinent information.

Changes at Posts 13 and 33 on March 22, 2025

Until further notice, the vehicle lanes at Post 33 will be closed. All vehicular traffic will need to enter the protected area through Post 8.

There will be two pedestrian lanes open at Post 33 from 5 a.m. through 8 a.m. After that time, the post will drop down to one pedestrian lane that will remain open until 8 p.m.

As a reminder, Post 13 has reduced from two vehicle lanes to one and will be closed completely at noon each day. This modification will cause some delays entering the site in the morning from both Posts 13 and 23 as well as increased commercial traffic at Post 23. Additionally, some backups may occur at Post 23 in the afternoons as employees leave the site.

Please exercise caution and practice patience as the site adjusts to these new traffic patterns.

DPO Process Notification

Consolidated Nuclear Security, LLC is committed to ensuring that all subcontractor employees know they are free to raise Environmental, Safety and Health (ES&H) technical concerns without fear of intimidation, reprisal or retaliation. Please see the DPO Process Notification, for more information.

Fraudulent Quote Requests/Purchase Order E-Mail Activity

The CNS Supply Chain Management department wants to alert suppliers to an active email scam involving request for quotations and issuance of purchase orders that purport to originate from CNS but are in fact fraudulent. While CNS cannot prevent this illegal activity, we want to inform our supplier community and promote awareness of such events.

We can share some common traits or themes of these fraudulent emails that may help reduce risk to your company in becoming a financial victim of this scam:

  • The email message may be poorly written, with misspellings and awkward sentence structure.
  • The senders email address is not the same as CNS standard email address domain. The email address domain for Y-12: xxx@y12nsc.doe.gov.
  • The message and purchase order requests shipment/delivery of products to non-CNS facilities.
  • The message will include an attachment that is designed to look like a purchase order, and includes a logo or other graphic, and a signature that may look legitimate.

The message and/or purchase order may even include a signature that looks legitimate, representing one of our management team or buyers.

If you believe you have received a fraudulent email that appears to be from CNS, please forward the message to Y-12's Procurement Department. in order to verify its legitimacy before responding to the e-mail or fulfilling the order. CNS will not be responsible for invoices for products ordered under this scam.

Suppliers should also contact their local law enforcement if they suspect that they are a victim of this scam. If you have received confirmation that the email is fraudulent, you may also file a complaint directly with the Internet Crime Complaint Center. The IC3 is a partnership between the FBI and National White Collar Crime Center.

Notification to Suppliers of Bluetooth/WIFI Restrictions

Consolidated Nuclear Security, LLC (CNS) values the business and trust of the suppliers and subcontractors that provide materials and services for the Y-12 National Security Complex in Oak Ridge, Tennessee. Suppliers and subcontractors are an integral part of CNS's goals and objectives, and the support demonstrated in helping CNS achieve those goals and objectives is appreciated.

However, recently it has come to our attention that some of our suppliers/subcontractors are unaware of the requirements regarding restrictions for Bluetooth and WIFI capable items being purchased from your companies and being delivered to locations within the Y-12 sites. Recently, there have been violations of these restrictions so we are taking this opportunity to provide you with additional guidance regarding these limitations. Read more...
