Description

The paper presents the first results of development of manufacturing technology of metallic chromium targets from highly enriched isotope 50Cr for irradiation in a high flux nuclear reactor to obtain a compact high-intensity neutrino source with low content of radionuclide impurities and minimum losses of enriched isotope. The main technological stages are the hydrolysis of chromyl fluoride, the electrochemical reduction of metallic chromium, the hot isostatic pressing of chromium powder and the electrical discharge machining of chromium bars. The technological stages of hot isostatic pressing of chromium powder and of electrical discharge machining of Cr rods have been tested

Abstract (Russian)

В статье представлены первые результаты разработки технологии изготовления мишени из обогащенного по изотопу 50Cr металлического хрома для облучения в высокопоточном атомном реакторе с целью получения компактного высокоинтенсивного источника нейтрино с низким содержанием радионуклидных примесей и минимальными потерями обогащенного изотопа. Основными стадиями технологии являются гидролиз хромил фторида, электрохимическое восстановление металлического хрома, горячее изостатическое прессование хромового порошка и электроэрозионная обработка хромовых стержней. Протестированы технологические стадии горячего изостатического прессования хромового порошка и электроэрозионной обработки хромовых стержней
