Abstract: 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.

Abstract: An enclosure for non-organic electronic components, the enclosure comprising: an outermost supporting structure; and a neutron barrier formed from a solid neutron reflecting material and a solid neutron absorbing material. The supporting structure and the neutron barrier define an inner cavity for housing non-organic electronic components located within a nuclear reactor core. The neutron barrier is for shielding electronic components housed in the cavity from neutrons and for surrounding electronic components housed in the cavity. The supporting structure is solid neutron transparent material, and the neutron reflecting material and the neutron absorbing material comprise powders contained within the inner cavity.

Abstract: A pulsed sonar-based wireless rod position indication system that utilizes nuclear radiation and high temperature tolerant hardware. The pulsed sonar-based rod position indication system can precisely locate the rod position by measuring the time of flight of a transmitted signal and by using the phase and amplitude information of the same transmitted signal. Primary and secondary antenna probes located in the interior of the control rod drive rod travel housing and full hardware redundancy provide for improved accuracy. The time of flight, phase and amplitude raw signals are inputted to a wireless data transmitter capable of sending the raw signals to a receiver antenna located elsewhere inside a containment for further processing.

Abstract: Apparatus for amplifying low level signals within a nuclear plant's containment building, derived from the ex-core nuclear instrumentation system. The system employs vacuum micro-electronic devices in place of conventional pre-amplifier assemblies to position the pre-amplifier assemblies closer to and within the vicinity of the ex-core detector outputs.
