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 buildup of radioactivity was measured on Type 304 stainless steel and carbon steel coupons exposed to reactor water in a test loop, which operated for ∼3 yr in a commercial boiling water reactor. Most of the activity buildup could be ascribed to 60Co. After an initial rapid increase, the activity buildup slowed down and kept increasing linearly up to 10 000 h of effective exposure to reactor water. No correlation was found between the 60Co activity in reactor water and the 60Co activity on the coupons. Preoxidation of Type 304 stainless steel coupons reduced the initial activity buildup. Carbon steel picked up much less activity than stainless steel during the tests. Measurements of the activity buildup after filtration of the primary coolant indicated that soluble impurities rather than particulates are primarily responsible for the radiation buildup phenomena. Increasing the coolant velocity also resulted in a reduction of the initial activity buildup on the coupons.
