 The 11th Technical Meeting on Lessons Learned from High Enriched Uranium Take-back Programmes, Tbilisi, Georgia, 19–22 June 2017

TUK-145/C package was created by Russian specialists at US DOE request in the framework of RRRFR Programme to ship radioactive materials with no activity limit (especially research reactor spent fuel) by air in compliance with the IAEA requirements for type C packages. Since 2011 certificates of approval for this package design were issued for shipments of HEU research reactor fuel from Viet Nam, Hungary, Uzbekistan to the Russian Federation, and HEU MNSR fuel from Ghana to People’s Republic of China. Different activities and characteristics of the radioactive content dictated the need to develop new canisters and baskets for use in the TUK-145/C, to classify and certify the package as type B(U) or C and consequently to develop different safety assessment reports to demonstrate the compliance to the IAEA requirements. This paper presents an analysis of different tasks and solutions addressed in Russian safety assessment reports, as well as questions raised by involved countries’ Competent Authorities and lessons learned from TUK-145/C licensing.

The TUK-145/C package with new basked to accommodate a MNSR core and fuel pins (together licensed as TUK-145/C-MNSR) was accepted as most appropriate to ship HEU MNSR fuel to People’s Republic of China since it allows expediting the shipment duration (by air instead of sea), reducing third countries transit challenges, optimizing the physical protection and emergency arrangements and assuring at the same time the highest level of safety required by IAEA regulations for radioactive materials packages.

In 2015, a consortium of the Radiation Safety Center under the Ministry of Emergency Situations, the Republic of Uzbekistan, and the Sosny R&D Company, Russia, started an IAEA project aimed at decommissioning of the FOTON Radiation-Technological Complex (RTC) in the Republic of Uzbekistan. The decommissioning implies immediate dismantling of all radiation-hazardous facilities, the main of which are the reactor and the isotope storage facility. The final state of the site shall provide for the possibility of its unrestricted use.

Ewa and Maria reactor SFAs have been shipped from Poland to Russia under the RRRFR Program since 2009. In 2009-2014, 7 shipments were implemented. They involved only on-land and sea transport. The 8th shipment that finished removal of HEU SFAs from Poland was carried out in September 2016. A decision was taken to use air transport for the 8th shipment to significantly shorten its duration and enhance NM physical protection. Air shipment of the spent fuel required specific engineering solutions to ensure nuclear and radiation safety. The presentation gives an insight in the exciting and complicated process of finding creative solutions by the developers of safe packages that often escape the public’s attention.
