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.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

The performance of a mass spectrometric system for measurement of tritium by 3He ingrowth method is described. Preparation and measurement includes three steps. The first step is to pump the dissolved gas from the environmental water samples stored in special glass bulb. The second step is the storage of the degassed water for a few months. In the final step the helium-3 formed from tritium is measured by mass spectrometer. In the course of tritium measurement there were some difficulties with the glass bulbs, such as pre-treatment of the glass, storage of the samples in deep freezer, long storage time, O-ring sealing. To solve these problems metal bulbs were built and applied with volume of six litres. The metal bulb was equipped with a metal valve. Three litres of water can be filled into the metal bulb. The large volume of the bulb causes an increase of degassing time, and a decrease of the storage time. The degassing of three litres of water needs twice one and a half hours in two days. The storage time is only two months in contrast to the half-year storage time of glass bulb. The background, the helium penetration from the air is less than using glass bulbs, because the metal bulb can be fitted to the inlet system via copper gasket instead of elastic O-ring.
