摘要： A method of irradiating multiple specimens within a core (14) of a nuclear reactor (16) that has a moveable in-core, radiation detector flux mapping system, wherein the core comprises a plurality of fuel assemblies respectively having instrument thimbles into which a radiation detector (12) of the flux mapping system can be inserted and travel through. The method comprises inserting a first specimen holder (48) containing a first specimen (72) at a lead end of a first drive cable (36) driven by a first drive unit (34), into a first instrument thimble in the core (14); remotely detaching the first drive cable (36) from the first specimen holder (48) and fixing an axial position of the first specimen holder within the first instrument thimble; withdrawing the first drive cable (36) from the reactor (16); attaching a second specimen holder (48) containing a second specimen (72) to the lead end of the first drive cable (36) driven by the first drive unit (34); inserting the second specimen holder (48) containing the second specimen (72) into a second instrument thimble in the core (14); remotely detaching the first drive cable (36) from the second specimen holder (48) and fixing an axial position of the second specimen holder within the second instrument thimble; withdrawing the first drive cable (36) from the reactor (16); in between the withdrawing step and the second inserting step inserting a moveable incore radiation detector (12) from the moveable in-core detector radiation flux mapping system, attached to a second drive cable (50) driven by a second drive unit (24), into and through a third instrument thimble; and withdrawing the moveable in-core radiation detector (12) from the reactor (16) after performing a flux mapping exercise.

摘要： A tool for use in servicing an LPRM assembly of a nuclear reactor vessel includes a structural member having a first bore that is structured to receive an LPRM device associated with the LPRM assembly, a headpiece provided at a first end of the structural member, and a nut engaging assembly slideably mounted on the structural member. The headpiece has a plurality of projections structured to mate with a plurality of bores provided in a seal of the LPRM assembly to enable the seal to be removed, and the nut engaging assembly has a housing that defines a second bore and that has first and second nut engaging portions. The nut engaging assembly is free to slide along the structural member and over the headpiece to a position wherein the engaging portions extend beyond the headpiece so that they may be used to remove the assembly nut.

摘要： To manufacture shaped bodies (10) filled with powder (22) for introduction into the reactor core of a commercial nuclear power reactor a plate made of a metal and/or metalloid is provided with one or more blind holes (14), the blind holes (14) are filled with powder (22), the blind holes (14) filled with powder (22) are reversibly sealed and shaped bodies are cut from the plate so that each blind hole (14) filled with powder (22) is surrounded by a shell made of a metal or metalloid. The powder-filled shaped bodies (10) are used in a ball measuring system for commercial nuclear power reactors and/or for the generation of radionuclides in said reactors.
