Cost of nuclear fuel that has to be replenished from time to time is the single most conspicuous component of costs of running the MARIA research reactor. The replenishment period depends primarily on reactor power and time of operation. However, some reactivity margin must be kept if the reactor is to run at high power densities during physical experiments and target irradiation. Reactivity margin is among the most important reactor operational parameters. Apart capability to run at high power levels, the parameter influences also reactor safety.
