Path planning in nuclear facility decommissioning: Research status, challenges, and opportunities

Nuclear Engineering and Technology, 2021
During nuclear facility decommissioning, workers are continuously exposed to high-level radiation. Hence, adequate path planning is critical to protect workers from unnecessary radiation exposure.

Development of self-actuated shutdown system for sodium-cooled fast reactor (Study on component materials suitable for fast reactors)

Nihon Kikai Gakkai ronbunshu, 2020
The self-actuated shutdown system (SASS) is a reactor shutdown system that is able to achieve passively de-tach the absorber rod based on the coolant temperature rise under the any type of abnormal conditions and then the absorber rods will be inserted ...

Human resource development and needs analysis for nuclear power plant deployment in Nigeria

Nuclear Engineering and Technology, 2022
The fulcrum of economic development is a sustainable supply of electricity. Nigeria is plagued with blackouts, with one of the lowest per capita electricity consumption in the world (circa. 120 kWh per capita).

Power of a quasi-spin quantum Otto engine at negative effective temperature [PDF]

arXiv, 2022
Heat engines usually operate by exchanging heat with thermal baths at different (positive) temperatures. Nonthermal baths may, however, lead to a significant performance boost. We here experimentally analyze the power output of a single-atom quantum Otto engine realized in the quasi-spin states of individual Cesium atoms interacting with an atomic ...

Spin squeezing of atomic ensembles via nuclear-electronic spin entanglement [PDF]

Phys. Rev. Lett. 101, 073601 (2008), 2008
Entangled many body systems have recently attracted significant attention in various contexts. Among them, spin squeezed atoms and ions have raised interest in the field of precision measurements, as they allow to overcome quantum noise of uncorrelated particles.

A Walk-Through of AGN Country -- for the somewhat initiated! [PDF]

arXiv, 2023
Some key issues in AGN and galaxy formation are discussed. Very successful Unified Models explain much of the variety of AGN with orientation effects; ingredients are shadowing by a dusty "torus" and relativistic beaming. A spinoff result is described which is important for the formation of massive elliptical galaxies.
