Fault Diagnosis to Nuclear Power Plant System Based on Time‐Series Convolution Neural Network

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
Nuclear power plant (NPP) is a highly complex engineering system which has typical internal feedback and strong component coupling. With these features, most NPP systems have high risk of radioactive release, which makes it essential to perform fault detection (FD) to the NPP systems.

Experimental Research for CHF Sensitivity of Heat Flux Distribution under IVR Conditions

Science and Technology of Nuclear Installations, Volume 2022, Issue 1, 2022., 2022
In‐vessel retention (IVR) through external reactor vessel cooling (ERVC) is one of the most effective severe accident mitigation measures in the nuclear power plants. The most influential issues on the IVR strategy are in‐vessel core melt evolution, the heat fluxes imposed on the lower head, and the external cooling of reactor pressurized vessel (RPV).

Sorting Integers on the AP1000

CoRR, 2000
Sorting is one of the classic problems of computer science. Whilst well understood on sequential machines, the diversity of architectures amongst parallel systems means that algorithms do not perform uniformly on all platforms. This document describes the implementation of a radix based algorithm for sorting positive integers on a Fujitsu AP1000 ...
