Competitive Bidding Relating to a Technology Development Project to Deal with Accidents of Nuclear Power Reactors and so on [Preliminary Announcement]

Hitachi-GE Nuclear Energy, Ltd. (hereinafter, referred to as “HGNE”) has announced that it will accelerate research and development for dealing with accidents of nuclear power reactors and so on (particularly, in regard to restoration from the accidents at the Fukushima Daiichi Nuclear Power Plant, Tokyo Electric Power Co.), in order to contribute to restoration from nuclear accidents and hazards.

As a part of this project, we plan to place orders for the individual items and thus we will hold competitive biddings for the items shown below in a month or so from now. Although we have not yet posted the bid manuals and specifications, please refer to the item names and the outlines of these items described below.

We plan to post the official bid manuals and specifications on the HGNE website (in Japanese). The official bid manuals and specifications are posted in Japanese and the English summary version of specifications are attached as reference. For this bid it shall be applied by Japanese subsidiary, and the documents shall be submitted in Japanese only.

(1) Item name: Robot 1, for investigating the wall surfaces of the torus room (the detailed design of a device for investigating the underwater wall surfaces of the torus room and the triangular corners [traveling robot])

Outline:

We ask for a detailed design for a survey robot for the purpose of checking for leaks from the wall surfaces of the torus room and the penetrating portions of the triangular corners in the basement of a nuclear reactor building.
The outline specifications of such a robot are as follows:

• The survey robot shall be capable of moving underwater and traveling on the surfaces of the torus room and the triangular corners, and shall include survey equipment necessary for detecting any leak from the penetrating portions.
• The survey equipment shall have a function to detect leaks from a position 5 meters away at maximum, using acoustic waves or the like.

(2) Item name: Robot 2, for investigating the wall surfaces of the torus room (the detailed design of a device for investigating the underwater wall surfaces of the torus room and the triangular corners [underwater swimming robot])

Outline:

We ask for a detailed design for a survey robot for the purpose of checking for leaks from the wall surfaces of the torus room and the penetrating portions of the triangular corners in the basement of a nuclear reactor building.
The outline specifications of such a robot are as follows:

• The survey robot shall be capable of swimming underwater and shall include a camera for investigating the penetrating portions.
• The camera shall have functions to pan and tilt, as well as zoom.

(3) Item name: Robot 3, for investigating the wall surfaces of the torus room (the detailed design of a device for investigating the upper part of the suppression chamber)

Outline:

We ask for a detailed design for a survey robot for the purpose of checking for leaks from the upper part of the suppression chamber in the torus room of a nuclear reactor building.
The outline specifications of such a robot are as follows:

• The survey robot shall be capable of autonomously traveling on the catwalk of the suppression chamber and shall be equipped with a pan-tilt-zoom camera.
• The camera shall be mounted on a platform, the height of camera shall be variable, and images shall be capable of being shot from a height of 3 meters at maximum.

(4) Item name: Detailed design of a survey equipment, for investigating the wall surfaces of the torus room

Outline:

We ask for a detailed design for a detector using ultrasonic beam equipped with a survey robot for the purpose of checking for leaks from the wall surfaces of the torus room and the penetrating portions of triangular corners in the basement of a nuclear reactor building.
The outline specifications of such a detector are as follows:

• The dimensions and weight of the detector shall be such that the detector can be equipped with an underwater traveling device.
• The distances of the underwater measurement shall be 5 meters at maximum.
• The ultrasonic beam width shall be approximately 50 mm.
• The frequency band shall be approximately 0.52 MHz.

(5) Item name: Detailed design of a survey robot for investigating the narrow sections outside a dry well (D/W)

Outline:

We ask for a detailed design for a survey robot for the purpose of checking for leaks from penetrating portions of the containment vessel at the narrow sections outside the dry well of a nuclear reactor building.
The outline specifications of such a robot are as follows:

• The survey robot shall have a function to autonomously travel from the entrance of the nuclear reactor building to a position right above a narrow section (within the building frame) in the targeted penetrating portion, and shall have an arm that can be lowered from an opening to the narrow portion of the building frame and shall include a pan-tilt-zoom camera at the tip.
• The camera shall be mounted on a platform, the height of camera shall be variable, and images shall be capable of being shot from the lowered positions of 5 meters at maximum.
