Special Issue Information

Dear Colleagues,

Nuclear energy has been one of the key low-carbon-emission sources of energy. As the world continues to grapple with climate change, it is imperative that we explore and develop new advancements in nuclear energy technology to provide efficient, clean, and safe energy solutions. In this context, we invite researchers, scientists, and industry experts to contribute to our upcoming Special Issue on the "Advancements in Nuclear Energy Technology".

This Special Issue aims to showcase the latest breakthroughs, innovations, and technological advancements in the field of nuclear energy, covering various topics, such as nuclear reactor design, modeling and simulation, operation and maintenance, nuclear fuel cycle optimization, safety and security, waste management, the integration of nuclear with other renewable energy sources, and so on.

We welcome the submission of original research articles, review papers, and case studies that can provide valuable insights into the current state and future prospects of nuclear energy technology.

The development and deployment of advanced nuclear energy technologies will play a crucial role in the global transition towards a carbon neutrality and sustainable energy future. Join us in this effort to promote the advancement of nuclear energy technology and contribute to a greener and more sustainable future for all.

(1) Background: Generally, in nuclear medicine and nuclear power plants, energy spectrum measurements and radioactive nuclide identification are required for evaluation of strong radiation fields to ensure nuclear safety and security; thereby, damage is prevented to nuclear facilities caused by natural disasters or the criminal smuggling of nuclear materials. High count rates can lead to signal accumulation, negatively affecting the performance of gamma spectrometers, and in severe cases, even damaging the detectors. Higher pulse throughput with better energy resolution is the ultimate goal of a gamma-ray spectrometer. Traditionally, pileup pulses, which cause dead time and affect throughput, are rejected to maintain good energy resolution. (2) Method: In this paper, an ultra-throughput boost (UTB) off-line processing method was used to improve the throughput and reduce the pileup effect of the spectrometer. Firstly, by fitting the impulse signal of the detector, the response matrix was built by the functional model of a dual exponential tail convolved with the Gaussian kernel; then, a quadratic programming method based on a non-negative least squares (NNLS) algorithm was adopted to solve the constrained optimization problem for the inversion. (3) Results: Both the simulated and experimental results of the UTB method show that most of the impulses in the pulse sequence from the scintillator detector were restored to δ-like pulses, and the throughput of the UTB method for the NaI(Tl) spectrometer reached 207 kcps with a resolution of 7.71% @661.7 keV. A reduction was also seen in the high energy pileup phenomenon. (4) Conclusions: We conclude that the UTB method can restore individual and piled-up pulses to δ-like sequences, effectively boosting pulse throughput and suppressing high-energy tailing and sum peaks caused by the pileup effect at the cost of a slight loss in energy resolution.
