ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

A day in the life of the nuclear community
The November issue of Nuclear News is focused on the individuals who make up our nuclear community.
We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.
In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.
The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

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.
