Abstract
An inspection apparatus for inspecting jet pump beams of nuclear reactors is provided. The inspection apparatus includes a base straddlingly mountable on a jet pump beam. The base includes a beam bolt opening sized to receive a jet pump beam bolt. A first transducer holder is coupled to a first side portion of the base, and a second transducer holder coupled to a second side portion of the base. The first side portion is opposed to the second side portion. Each holder includes an adjustment cylinder configured to contact the jet pump beam when activated.

An inspection apparatus for inspecting jet pump beams of a nuclear reactor, the nuclear reactor comprising at least one jet pump with each jet pump comprising a jet pump beam and a jet pump beam bolt, said inspection apparatus comprising:
- a base straddlingly mountable on a jet pump beam, said base comprising a beam bolt opening sized to receive a jet pump beam bolt;
- a first transducer holder coupled to a first side portion of said base;
- and
- a second transducer holder coupled to a second side portion of said base, said first side portion opposite to said second side portion, each said holder comprising an adjustment cylinder configured to contact the jet pump beam when activated.
A method of inspecting a jet pump beam in a nuclear reactor, the reactor comprising at least one jet pump with each jet pump comprising a jet pump beam and a jet pump beam bolt, said method comprising:
- mounting an inspection apparatus on a jet pump beam;
- and
- scanning the jet pump beam with the inspection apparatus;
- said inspection apparatus comprising:
- a base straddlingly mountable on the jet pump beam, the base comprising a beam bolt opening sized to receive the jet pump beam bolt;
- a first transducer holder coupled to a first side portion of the base;
- and
- a second transducer holder coupled to a second side portion of the base, the first side portion opposed to the second side portion, each said holder comprising an adjustment cylinder configured to contact the jet pump beam when activated.
