Process for the preparation of powder-filled moldings, moldings for introduction into a power reactor and their use

摘要

To produce molded articles (10) filled with powder (22) for introduction into the reactor core of a power reactor, a plate of metal and / or semimetal is provided with one or more blind holes (14) filling the blind holes (14) with powder (22) , reversibly closed blind holes (14) filled with powder (22), and shaped bodies (10) cut out of the plate so that each blind hole (14) filled with powder (22) is surrounded by a shell formed from the metal or semi-metal. The powder-filled molded articles (10) are used in a spherical measuring system for power reactors and / or for the production of radionuclides in power reactors.
