Summary

The analysis of the effective normative documents, developed for the "Ukryttya" object was performed to support the process of its transformation into an ecologically safe system. The problems related to the accounting and control of emergency nuclear materials that may arise during fuel-containing materials retrieval are shown based on the analysis. In particular, it was shown that in the "Regulations on implementation of the Agreement between Ukraine and the International Atomic Energy Agency in field of Nuclear Safeguards application to all nuclear material for all peaceful activities of Ukraine" (INFCIRC/153), signed between International Atomic Energy Agency and member stares not possessing nuclear weapon, only one definition - "stored waste" (paragraph 107) is applicable to emergency nuclear material of the "Ukryttya" object. There are no recommendations regarding transfer to "stored waste" INFCIRC/153. The normative and technical documentation developed to the date and agreed with IAEA also doesn’t regulate such a transfer. Absence of normative and technical documentation regulating transfer of emergency nuclear materials into "stored waste" can lead to the problem in management of more than 100 tons of High Level Waste not covered by any of the regulatory schemes for Radioactive Waste Management.

Keywords: nuclear materials, fuel-containing materials, IAEA Safeguards, accounting and control of nuclear materials, material balance area, nuclear material regeneration.
