TL;DR: In this paper, the concept of effective cross-section has been proposed for thermal nuclear reactions with Breit-Wigner resonance, and the effect of varying the neutron temperature is considered.

TL;DR: In this article, the surface oxidation of UO2 fuel pellets at 229 to 275°C has been monitored by X-ray diffractometiy and the existence of β-UO2.33 as a significant intermediate product of oxidation was confirmed, and a method for its quantitative estimation on the pellet surface was derived.

TL;DR: In this paper, the influence of Nb content and heat treatment on the structure and isothermal corrosion behavior of ZrNb alloys at 300, 360 and 400°C in static heavy water and steam (1500 psi) was presented.

TL;DR: In this paper, an analytical model has been developed to describe the release of radioactive iodine and noble gas from defective fuel into the primary coolant of a power-reactor and an analytic treatment has also been used to model the low-temperature release of fission products from small particles of uranium-bearing compounds (uranium contamination) deposited on in-core surfaces.
