Summary

It is shown that in current technological reglament of the "Ukryttya" object there is no guidance for permissible values selection in channels of fuel-containing materials nuclear-physical parameters control. Threshold settings for neutron flux density that were listed in the reglament are given without proper justification and do not provide a suffi-cient level of subcriticality control effectiveness. The necessarity to develop convenient for practical using method for threshold settings determination on basis of compromise between strictly scientific approach and easy usage and to incorporate it to the reglament is pointed out. Recommendations for content of such a method are given. Main principles for threshold settings determination for the "Ukryttya" object nuclear safety control effectiveness are analized.
