Document Type and Number:
Japanese Patent JP6356049
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a communication system and a communication method that can stably communicate regardless of the position of an underwater robot in a nuclear reactor pressure vessel.SOLUTION: A communication system comprises: a communication device 5 placed in water housed inside of a nuclear reactor pressure vessel 11 made of conductor; and a communication device 1 that is for communicating with the communication device 5, placed outside of the nuclear reactor pressure vessel 11, and includes a set of feeding points 6, 7 for applying and detecting a communication signal 1a related to communication to the nuclear reactor pressure vessel 11. The system is arranged such that the shortest path connecting the feeding points 6, 7 along the nuclear reactor pressure vessel 11 goes through the vicinity of a point on an inner wall of the nuclear reactor pressure vessel 11, the distance between the point and the communication device 5 being the shortest.SELECTED DRAWING: Figure 1
