The NBL Program Office is responsible for overseeing the production, certification and sales of special nuclear certified reference materials. It collaborates with U.S. Department of Energy programs, national laboratories, and international partners to meet the Nation's needs for reference materials used for calibration of measurement systems, quality assurance, and research and development.
The NBL Program also conducts interlaboratory proficiency testing programs (Safeguards Measurement Evaluation Program) to provide independent validation of facility nuclear material measurement quality/capabilities and to examine ‘real-world’ method performance. Materials, produced as certified reference materials by the NBL Program Office, are distributed to participants as "unknowns." Labs submit results, and the NBL Program Office generates an evaluation report indicating degree of agreement with the certified values. Participation is open year-round. Interested facilities should contact NBLSales@nnsa.doe.gov for a list of materials, prices and with any questions. The NBL Program Office will issue annual reminders of the availability of materials, and a price list will be added to this page in the future. Questions may also be addressed to Peter Mason, NBL Program Office Director, at email@example.com.
Certified Reference Materials
PLEASE NOTE: Due to the COVID-19 situation in the US, shipment of NBL materials is limited and delayed. If you have an urgent need, please contact us via email.
The NBL Program Office provides Certified Reference Materials for use in nuclear and nuclear-related analytical measurement activities. Availability is consistent with existing U.S. regulations and international agreements regarding possession of such materials.

These organizations have published regulations and procedures for packaging and shipping dangerous (hazardous) goods to safely transport these materials. Such regulations and procedures are very specific and do not allow exceptions. NBL reserves the right to select the proper packaging and shipping mode to ensure shipments comply with these regulations and procedures.
Except for shipments made in error, NBL certified research materials are not returnable. Requests to return the materials must be made within 30 days of receipt and in writing to NBL. Immediately contact NBLSales@nnsa.doe.gov if there are any issues with a shipment.
