TL;DR
This paper investigates how temperature-dependent cross-sections of uranium and plutonium isotopes influence blow-up regimes in neutron-multiplying media, revealing conditions that can cause rapid neutron flux and temperature increases.
Contribution
It introduces the temperature effects on cross-sections of uranium and plutonium isotopes and discusses their role in initiating blow-up regimes in nuclear media.
Findings
238U and 239Pu cross-sections increase with temperature between 1000-3000 K.
Under certain conditions, this increase can lead to blow-up modes.
Features of blow-up regimes are analyzed and discussed.
Abstract
It is shown that the capture and fission cross-sections of 238U and 239Pu increase with temperature within 1000-3000 K range, in contrast to those of 235U, that under certain conditions may lead to the so-called blow-up modes, stimulating the anomalous neutron flux and nuclear fuel temperature growth. Some features of the blow-up regimes in neutron-multiplying media are discussed.
