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.

The mean time between failures (MTBF) estimation has been intensively investigated in recent years. MTBF can be used to decide on a maintenance strategy or inspection timeline intervals for the RSG-GAS reactor (or GAS multipurpose reactor). The RSG-GAS reactor is a pool-type reactor where light water is used as a moderator, coolant, and shielding. The purpose of this paper is to propose the nonhomogeneous Poisson process (NHPP) model to obtain the MTBF estimation value. Thus, the RSG-GAS reactor installation would have higher safety, a longer lifetime, and substantial reliability with a minor failure rate, including the subcomponents of the JE01-AP03 primary centrifugal pump.
In this research work, the methodology processes data accumulation and estimates the parameters of the NHPP model to determine the maintenance schedule or inspection timeline intervals based on the MTBF value when the confidence level reaches the targeted percentage. The results indicate that a MTBF estimation has been acquired for the RSG-GAS reactor installation. In the implemented case, an inspection timeline is defined for the JE01-AP03 primary centrifugal pump with a reliability growth value of 0.41 and a MTBF estimation circa 42 days.
