NUCLEAR SUBMARINES WITH DAMAGED REACTOR INSTALLATIONS: BASIC ENGINEERING SOLUTIONS AND SAFETY-RELATED PROBLEMS

摘要

Hazardous (inadmissible) radiation situation inside Reactor Compartments (RCs) represents a distinctive characteristic of the damaged Nuclear Submarines (NSs) giving no way of performing pre-defueling operations using standard technologies. To conduct works in RCs of the damaged NSs and perform their rehabilitation, one needs developing individual technologies and special devices taking into account specific implications of the accidents, which caused withdrawal of every such NS from service. If observing special conditions, defueling and subsequent dismantlement of some damaged NSs is possible even under their present-day technical and radiation situation; at the same time defueling and dismantlement of other damaged NSs is still impossible. This means that presently one has to do with the following two main problems.
