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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

Simulations of FLECHT and FLECHT-SEASET, unblocked forced flow reflood tests, were performed using RELAP5/MOD2 code reflood capabilities. The predictions of the high flooding injection rate and steam cooling tests were in good agreement with the measurements. The low flooding rate tests showed a tendency to predict lower peak cladding temperatures than the data and unrealistic void fraction oscillations. The spikes in void fraction histories were flow-regime dependent. The prediction for the quench times at the upper bundle elevations was overestimated.
