Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Why should safeguards by design be a global effort?
Jeremy Whitlock
I can’t think of a more exciting time to be working in nuclear, with the diversity of advanced reactor development and increasing global support for nuclear in sustainable energy planning. But we can’t lose sight of the need to plan for efficient international safeguards at the same time.
Global nuclear deployment has been underpinned since 1970 by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), making it a key customer requirement for governments to demonstrate unequivocally that the technology is not being misused for weapons development.
The International Atomic Energy Agency (IAEA) has helped verify this commitment for more than 50 years, but it has never safeguarded many of the advanced reactors (and related fuel cycle processes) being developed today.

The Cernavoda Tritium Removal Facility (CTRF) will be built at Cernavoda Nuclear Power Plant (NPP) for tritium removal and recovery from tritiated heavy water during the operation of CANDU reactors.
A Cryogenic Distillation process in combination with a Liquid Phase Catalytic Exchange (LPCE) process is used for tritium removal/recovery from tritiated water.
According with the regulation “Implementation of a Nuclear Material Accountancy and Control System by Operators of Nuclear Installations (2009/120/Euratom)” of the European Commission, the operators of nuclear facilities are obliged to provide to the European Commission, regularly detailed information about their installations and the nuclear material in their possession. Also, according with the regulations of the Commission for Control of the Nuclear Activities (CNCAN) from Romania, a nuclear facility is mandated to apply a control system for nuclear guarantees.
Therefore, an important issue for CTRF, should be the tritium accountancy in the facility. In order to quantify the tritium inventory in the facility, the subsystems necessary for tritium accountancy in normal operation and also during facility shut down should be identified.
Although the facility is, still in the design and construction phase, it is required to identify adequate instrumentation to ensure the implementation of the safeguards requirements. This technical note presents the methods and relevant tritium measurements instrumentation to quantify the tritium inventories from the main systems of the facility.
