Title: High conversion heavy water reactor
Inventor: MIYAWAKI YOSHIO
IPC: G21C3/328
Filed: 1987-09-30
Abstract: PURPOSE:To attain a high conversion rate by arranging fuel rods for which mixed uranium-plutonium oxide fuel is used to a square grid shape at the pitches equal to the pitches in an ordinary light water reactor and using heavy water as a moderator. CONSTITUTION:The mixed uranium-plutonium oxide fuel is used for the fuel rods 10. The basic arrangement of the fuel rods 10 are equal to the arrangement in a pressurized water reactor; i.e., the many fuel rods are arranged in the square grid shape at the relatively wide pitches. A guide pipe 12 for in-pile instrumentation exists at the center of a fuel assembly. Many control rod guide pipes 14 are dispersed and disposed to a nearly square shape and control rods 16 are inserted therein. The heavy water in common use as the moderator and coolant is passed in the fuel assembly. The moderating power of the heavy water is lower than the moderating power of the light water and, therefore, if the heavy water is used as the moderator in such a manner, the high conversion rate is obtainable in spite of the large pitches of the fuel rods 10 and the large ratio of the heavy water volume to the fuel volume.

IPC: G06F9/305
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To fast perform decimal to binary conversion by providing a decimal to binary converter with which an address calculating part converts decimal data into binary data. SOLUTION: A memory address calculating part 105 of a bit operation processor BPU (binary coded decimal) 10 has an operand register 105a and a decimal to binary converter 105b. After the converter 105b converts decimal data of BCD notation which is stored in the register 105a into binary data, the address of data RAM that shows the binary data is accessed by BP-D-ADR (data input signal) 703, and data which sent from the data RAM via BP-D-RDAT (address output signal) 704 is stored in the register 105a. After that, the data is sent to a bit operation executing part 107. Thereby, a user can handle the address of the data RAM in a decimal notation, and also, the control of a hardware can be simplified in comparison with a conventional computer system in which a decimal converter is connected through an I/O device.
