A thermal-neutron reactor core includes: a solid moderator expanding to a lengthwise direction; a fuel in the moderator, parallel to the lengthwise direction of the moderator, the fuel containing a fissile material; a cooling tube parallel to the lengthwise direction of the moderator; and a plurality of kinds of burnable poison included in the fuel. The may contain a metal hydride. Furthermore, the plurality of kinds of burnable poison may include one burnable poison containing a concentration of one particular isotope of that one burnable poison.

An object tracking device (,) tracks an object to find a position of the object. A first arithmetic circuit (,) calculates the variation of the position of the object with time, a second calculating circuit (,) determines a characteristic value representing the movement of the object. A third arithmetic circuit (,) determines a moving pattern of the object. A display unit (,) displays the characteristic value representing the movement of the object.

Apparatus for detecting a moving state of an object

An imaging glass window and an illumination glass window which are opposed to each other define a sample chamber, and the sample chamber holds sample liquid containing particulates. Light from the particulates is magnified by a zoom magnifying glass via the imaging glass window, optical axis angle changing means and optical axis length changing means and imaged by a CCD camera. An image of the sample liquid is supplied to image control means, and the optical axis angle changing means is operated by the image control means to change an optical axis of the light from the sample liquid and shift an image of an intended one of the particulates in the sample liquid to the center a camera lens of the cameraeen. Concurrently the zoom magnifying glass is set at a required magnification by the control means.
