Principles of Handling Decommissioned Ship Reactors

Abstract

Decommissioning of ship reactors is a very long procedure to be preceded by some preparatory work, including the technical operations that can be performed at a base for technical maintenance of nuclear powered ships. There, unloading of spent nuclear fuel (SNF) from reactors in conformity with the approved technology, washing of the primary coolant circuit with the help of the ion exchange filter, removal of the filter ionites, drying and sealing of the technological circuits, etc. should be accomplished. The base can be quite naturally used for revising the actual condition of a reactor facility (RF) equipment, reinforcement, instrumentation, etc. to determine the suitability of the afore-mentioned apparatus and appliances for reuse in other ships. It is expedient to dismount reusable and readily removable devices.
