Embodiment 2

[0048] In the second embodiment, due to the limited design space of the main control room, some functions of the special security disk are combined, and the special security disk can be designed as figure 2 Compared with Embodiment 1, the configuration of the dedicated security disk 2 shown is simplified as follows:

[0049] The position of the emergency shutdown and special safety facility management button group 22 has been moved to the lower half of the leftmost area of ​​the special safety disk 2 .

[0050] By developing a new type of equipment, the third group of NC-VDUs will be upgraded to a safety level, and at the same time replace the function of the recorder.

Embodiment 3

[0052] If for some small ships, the space of the main control room is narrow, the design scheme of the third embodiment can be adopted, and the special safety disk is designed as image 3 Compared with the second embodiment, the configuration of the dedicated security disk 3 shown is simplified as follows:

[0053] Since the special safety panel 3 has been provided with emergency shutdown and special safety facility management button group 22, according to the regulations in NUREGBTP 7-19, if the realization of some functions of the button group 22 can avoid the digital protection system, through safety-related platform (which will not be affected by the common failure of the protection system, such as using a relay analog circuit), then the button group 22 can be used to replace the second group of non-safety level monitoring units in Embodiment 2 (such as figure 2 The non-safety display screen 41 and the manual hard operation button 42). Furthermore, the third group of non...

Embodiment 4

[0055] If for some small ships, the space of the main control room is small, the design scheme of the fourth embodiment can also be adopted, compared with the second embodiment, the following simplifications are done:

[0056] Incorporate the diversified protection functions designed for digital protection system failures and the functions of mitigating severe accidents into one non-safety level monitoring unit, such as Figure 4 The non-safety level monitoring unit shown (including the non-safety level display 61 (NC-VDU61) and manual hard operation keys 62 in the far right area) further reduces the size of the dedicated safety disk and reduces the area of ​​the main control room .

[0057] This solution also meets the requirements of NUREG / CR 6303 for the defense-in-depth system. There are at least 2 sets of monitoring equipment on different platforms, which can not affect the performance of related functions of the second set of monitoring equipment when the first set of mo...

Abstract

The invention provides a configuration system for a special safety disk of a main control room of a nuclear power ship. The system is used in the marine nuclear power ship. The system comprises at least one safety level monitoring unit which uses safety level display screens to monitor safety level equipment and parameters, and at the same time provides a safety level important post-accident parameter monitoring function, at least one non-safety level monitoring unit which consists of a corresponding non-safety level display screen and corresponding manual hard operation buttons, an information recording unit, and an emergency shutdown and special safety facility management button group. According to the invention, the system fills the gap in the technology of the marine nuclear power shipin China, and provides a feasible scheme for developing and manufacturing the marine nuclear power ship; and the special safety disk provided by the invention integrates multiple functions of the main control room in an onshore nuclear power plant, can be arranged in the main control room of various types of nuclear power ships, and is not limited to the size of the main control room of the ship.

Description

technical field [0001] The invention relates to the technical field of nuclear power ships with power generation function, in particular to a configuration system of a dedicated safety disk for a main control room of a nuclear power ship. Background technique [0002] In our country, marine nuclear-powered ships with power generation functions are still a blank field. With the exploration and expansion of marine resources, the gap in this field will be gradually accelerated in the future, and the civilian use of marine nuclear-powered ships will gradually follow. developed. [0003] How to maintain the safe and stable operation of the nuclear power part of the ship has become the focus. For the ship, the main control room provides guarantee for the ship's navigation, operation and power generation. Therefore, the design and configuration of the main control room of the nuclear power ship In-depth research is required. The design of the main control room should not only con...
