In a control system for a plant controlling a plant such as a nuclear power plantwith use of a plurality of digital control devices, the plurality of digital control devicesinclude a plurality of control functionsto, and the plurality of control functionstoare provided in the plurality of digital control devicesin a distributed manner so that the digital control devicesmay not fall below safety standards preset by safety analyses. This provides a control system for a plant using the plurality of digital control devicesand configured to control a plant safely even when a digital control device is failed.

Control system for plant

Provided are a safety protection system facilityoutputting a normal actuating signal Sin a case where the safety protection system facilitycontrols actuation of a unit provided in a nuclear facility to a safe side based on an abnormality detecting signal output at the time of occurrence of an abnormality in the nuclear facility, and where this causes the unit to be actuated normally, and a CCF countermeasure facilityoutputting a CCF-case actuating signal Sactuating the unit to a safe side in a case where the CCF countermeasure facilitydetermines from output results of the abnormality detecting signal and the normal actuating signal Sthat the unit is not actuated normally at the time of occurrence of the abnormality in the nuclear facility.

Control system for nuclear facilities

A coil conductor for a dynamoelectric machine which is a coil conductor to be inserted into slots of an iron core of a dynamoelectric machine, the coil conductor being made of a plurality of wire elements compression-bonded to each other by press-forming so as to have a substantially rectangular cross-section. The wire elements may be twisted by at least 360 degrees and the twisted wire elements may be further twisted. The coil conductor includes straight sections and crossover sections, providing an overall shape of a crank wound in a serpentine manner and the straight sections have different intervals that are different in accordance with the different periodical numbers th and ( &plus;1) th. The coil conductor for a dynamoelectric machine may further include an electrical insulating material disposed around the conductor of a square cross-sectional shape that is formed by simultaneously pressing the conductor bundle with an electrical insulating material placed therearound before press-forming.
