This review describes main types of organic polymers, which are now widely used and are the most resistant to ionizing radiation. It presents modern approaches to creation of radiationshielding composite materials based on polymer matrix and various types of fillers. It also discusses the efficiency of sizes of fillers' micro-and nanoparticles in terms of improving radiation resistance of organic polymer materials.

В данной статье рассматриваются некоторые результаты организованных Международным энергетическим агентством иссле-дований технологических проблем обращения с радиоактивными материалами термоядерных энергетических установок (ТЭУ) после извлечения из них заменяемых компонентов и после вывода ТЭУ из эксплуатации. Основные исследования направлены на разработку требований по выводу облучённых материалов из-под контроля надзорных органов, определение возможности применения ручных процедур или дистанционного оборудования при переработке материалов для их возвращения в производ-ственный цикл, непрерывную оценку радиационной опасности от облучённых материалов термоядерных установок и их детри-тизацию. Чтобы расширить фронт работ по выбору функциональных материалов для первой стенки термоядерного реактора (помимо вольфрама как основного кандидатного материала покрытия), рассмотрены потенциально альтернативные материалы, такие как цирконий, ниобий, молибден, гафний и тантал, с точки зрения их возможной активации нейтронами, распыления в результате эрозии и переосаждения, влияния на переходные процессы в плазме и возможности их возвращения в производст-венный цикл.Ключевые слова: радиоактивные материалы, безопасность термоядерной установки, Международное энергетическое агентст-во, нейтронная активация, тритий. Some results of the collaborative studies organized by the International Energy Agency (IEA) in the area of technological problems of the fusion radioactive materials management following the withdrawing of replaceable components from the fusion facilities and decommissioning of these facilities are addressed in this paper. Key issues include clearance conditions, hands-on and remote recycling procedures, radioactive fusion material hazard assessment, and detritiation of activated materials. To broaden the options for fusion development, researchers examined five potentially alternative high-Z materials: zirconium, niobium, molybdenum, hafnium, and tantalum from four standpoints: neutron-induced activation, sputter erosion/redeposition, plasma transient response and recycling possibility.

“…Especially, attenuation of neutrons is an important aspect in radiation shielding context. Generally, the main material used in design and development of hybrid neutron shielding materials are polymers and their derivatives thanks to the rapid development of polymer technology between 1960 and 1990 6 . In above‐mentioned harsh conditions, the conventional shielding materials (eg, concrete, water, neat polyethylene etc.)…”

The aim of this study is to develop a novel shielding material against both neutron and gamma rays. For this purpose, multi-functional polyimide nanocomposites with two different nanoparticles fillers, that is, h-BN and Gd 2 O 3 , was designed and fabricated through conventional melt extrusion processing techniques via laboratory batch twinscrew compounder. The morphology and structure of both fabricated nanoparticles and their nanocomposites were characterized by SEM, TEM, XRD. Moreover, the mechanical properties of nanocomposites were investigated. High energy neutron and gamma radiation shielding performance of nanocomposites having h-BN and Gd 2 O 3 were examined in detail by means of Neutron Howitzer. The results indicated that the presence of nanoparticles in polyimide significantly influenced both the radiation shielding and mechanical properties of nanocomposites. It was found that nanocomposites could be used for high energy neutron shielding purposes in nuclear reactor system, nuclear waste disposal applications, space, and aeronautics industries.
