El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

An application of a cylindrical discharge tube type fusion neutron beam source for medical purpose was investigated. Practicality and possibility of the medical irradiation plan were evaluated from the standpoint of engineering and medicine.Cancer treatment by BNCT (Boron Neutron Capture Therapy) was selected as an effective application to take advantage of this neutron source. Neutron transport in a phantom was calculated with the MCNP5 (Monte Carlo Neutron Particle calculation code version5), and the distribution of dose on the affected part medicated with a boron agent suggested satisfactory focusing.Since this neutron source is small size, it is designed to irradiate the affected part from many directions by crossfire irradiation. Flexibility of attitude and operation modes permits irradiation in a supine position from arbitrary directions. Because of low neutron flux, irradiation therapy is planned for multi-fractionation in a manner similar to CHART (Continuous Hyperfractionated Accelerated Radio Therapy). Crossfire irradiation and CHART will allow us to achieve new cancer therapy with a relatively lower dose rate than conventional BNCT. It causes apoptosis selectively to a cancer cell, reducing side effects and a patient's recuperation burden. This result suggests the possibility of advanced cancer treatment which improves QOL (Quality of Life) of the patients.
