Title: Cooling Method For Reactor Molten Core Melt And Cooling Control System For Reactor Molten Core
Inventor: Sidorov Aleksandr Stalevich
IPC: G21C17/112
Filed: 2018-12-28
Granted: 2023-09-17
Abstract: The invention relates to safe operation support systems of nuclear power plants (NPPs) at severe accidents, in particular, to methods and systems for cooling and cooling control of the reactors molten core. The technical result of the claimed inventions is to increase the safety of NPP, cooling efficiency of the molten core of a reactor. The objective of the claimed inventions is to increase the efficiency of cooling the molten core of a reactor by safely removing the heat load from the molten metal mirror, ensuring the elimination of vapour explosions leading to the destruction of the localization area of accidents, the reactor cavity and the containment. The technical result is achieved by changing the principle of cooling the reactor molten core, which consists in the fact that after the molten core destroys the reactor vessel, the conditions for subsequent cooling of the molten metal are determined by the characteristics of the trap casing, but not of the reactor. Besides, the technical result is achieved due to the installation of temperature sensors and level gauges designed to monitor the cooling process of the molten core of a reactor. 2 claims, 1 fig.of drawings.

Title: Communication system & network
Inventor: ELLIOT GRUENBERG
IPC: H04L5/00
Filed: 1982-05-13
Granted: 1988-10-17
Abstract: The communication system connects users of the system by one or more two-way links or loops, through intermediately transponders or nodes.  A control carrier having a characteristic control carrier frequency is assigned to each system user.  The control carrier is a signal which does not contain intelligence or information (modulation), but which establishes the linkage between subscribers, enables the intelligence in specific directions and hence along specific paths. To use the system, the calling part selects a control carrier frequency which is complementary to the control carrier frequency of the called party.  Selection of this control carrier frequency automatically enables a transmission path between the calling party and the called party.
