Zero-power reactors are operated only at such lo w power (watts to kilowatts) that power effects like - fuel burn-up, - poisoning or - temperature effects can be virtually neglected during the time of the tr aining. Hence, every start of such a zero-power reactor corresponds, regarding its nuclear part, to a cold start-up of a power reactor.
