Alpha particle detectors are crucial for the operation and decommissioning of nuclear power plants. In these environments they are exposed to large doses of high energy alphas, neutrons and other forms of radiation1. Robust, high resolution, high sensitivity and low background detectors are an absolute necessity.Diamond solid-state detectors are excellent alternatives to conventional scintillation and gas filled detectors. Diamond’s wide band-gap and large carrier mobility results in reduced leakage currents, fast signal collection2 and its radiation tolerance is unmatched by other semiconductors3. Furthermore, its low atomic number leads to a low capture cross section for gamma radiation, which reduces background…

The School of Science welcomed 11 new faculty members in 2024.Shaoyun Bai researches symplectic topology, the study of even-dimensional spaces whose properties are reflected by two-dimensional surfaces inside them. He is interested in this area’s interaction with other fields, including algebraic geometry, algebraic topology, geometric topology, and dynamics. He has been developing new tool kits for counting problems from moduli spaces, which have been applied to classical questions, including the Arnold conjecture, periodic points of Hamiltonian maps, higher-rank Casson invariants, enumeration of embedded curves, and topology of symplectic fibrations.Bai completed his undergraduate studies at Tsinghua University in 2017 and earned…

Parsons, Kansas, will be the site of a California startup’s first ever 1-mile-deep nuclear reactor — with support from county commissioners, both Republican Kansas U.S. senators and Democratic Gov. Laura Kelly’s administration.Deep Fission will hold a ceremonial groundbreaking on Tuesday at Great Plains Industrial Park. Company leaders hope to receive U.S. Department of Energy authorization and get its nuclear reactor up and running by next Fourth of July.The company is part of a presidential pilot program that aims to demonstrate new reactors by then. After that, Deep Fission hopes to pursue commercial operations. “The industrial park is looking to bring…

United States-based Deep Fission has announced that Parsons in Kansas will be the site for its full-scale commercial small nuclear reactor. The company has selected Great Plains Industrial Park in Parsons, Kansas, as the site for its advanced reactor pilot project, as per the announcement made on Thursday. The groundbreaking ceremony for the small modular pressurized water reactor in boreholes one mile underground will be held on December 9. This marks a significant leap for Deep Fission’s first demonstration of the Gravity Nuclear Reactor. The company is participating in the US Department of Energy’s (DOE) Reactor Pilot Program, an initiative…

The process and equipment design of multi-modular NPPs is nearly the same as that of single modular NPPs. The major difference between the multi-modular and single modular NPPs focuses on the control and operation that is mainly provided by the CCS. The multi-modular coordinated control is the mechanism playing a central role in the realization of multi-modular scheme, giving the plant responses in normal and abnormal scenarios. In this section, the coordination mechanism inside a single reactor module and between two modules are proposed, giving the CCS design of HTR-PM plant.Coordinated control of a single reactor moduleAs illustrated in Fig. 2,…

Machine configurationsExtensive details of the original configuration of Norman are given elsewhere13,14.Both the original and present forms are illustrated in Fig. 1. In the Norm configuration, plasmas primarily reside in the CV bounded at each end by divertors. Between the CV and divertors is a fueling region located between the M1 magnetic coil (closest to the CV) and the mirror plug (MP) (closest to the divertor). The M2 coil adjusts the field in the fueling region to facilitate neutral-gas ionization and refueling on field lines closer to the separatrix. Current is driven in the plasma by 8 neutral beams with 15 keV…
