Possibility of a life-time extension for wwer-1000 reactor pressure vessels beyond the design period

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2020
At present a life-time extension for WWER-1000 reactor pressure vessels is an actual issue in Ukraine. For a decision about the life-time extension it is needed to assess mechanical properties and the critical brittleness temperature TK for the RPV ...

Turn-off time improvement by fast neutron irradiation on pnp Si Bipolar Junction Transistor

open access: yesNuclear Engineering and Technology, 2022
Long turn-off time limits high frequency operation of Bipolar Junction Transistors (BJTs). Turn-off time decreases with increases in the recombination rate of minority carriers at switching transients.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Response of RadFET dosimeters to high fluences of fast neutrons [PDF]

open access: yesIEEE Transactions on Nuclear Science, 2005
We present irradiation experiments carried out on RadFETs in the high-intensity T2 neutron beam at the CRC-UCL in Belgium. The aim of the test was to characterize the neutron response of RadFETs in view of their use as an integrated part of a radiation-monitoring sensor for the CERN Large Hadron Collider (LHC) experiments.

Fast neutron irradiation effects on Si- and GaN-based avalanche photodiodes

open access: yesResults in Physics, 2022
We report the behaviour of the dark current and gain characteristics of Si- and GaN-based avalanche photodiodes (APDs) irradiated by fast neutrons. For Si-based APDs, the dark current increases with the increase of neutron fluence, indicating that the ...
