*Title: Atomic Power Plant Safety Monitoring System employing IoT Integrated Hyper-Ledger Cloud Module
*Field of Invention: Blockchain employed in engineering safety
^Background Art including citations of prior art: There are no
systems to employing Blockchain technology for secure data collection and storage of atomic power plant related safety parameters.
^Objective of invention (the invention's objectives and advantages, or alternative embodiments of the invention): The objective of the invention is to collect and store the sensor data pertaining to safety parameters in an atomic power plant in a tamper proof manner employing Blockchain for safety auditing.
* Summary of Invention:
This invention employs a Blockchain system for storing data collected by sensors fitted at atomic power plant. Safety is the highest priority in atomic power plants. The collection of data pertaining to parameters of atomic power plant and storing them in a tamper proof manner is of great importance for safety standard auditing. Three most important parameters pertaining to atomic power plant safety: the nuclear radiation, the pressure in the stream generator exchanger and the temperature of the reactor. The nuclear radiation is measured by conventional neutron detectors. Digital bellow is employed for measuring pressure inside exchanger circuit. Resistance temperature detector is employed to measure temperature in the moderator. All the collected data from the sensor are processed and converted into digital data at the locally place Electronic Computing Unit and sent to a dedicated or cloud server via Internet employing and IoT Module. Data analytics can be performed on the collected data and predictive models created to predict any accidents caused due to technical operations of the plant. There are incidents of nuclear power plant accident in India at plants located in Kalpakkam and Tarapur.

* Detailed description of the invention:
As shown in Figure 1, the conventional neutron detectors (1) measures the nuclear radiation in the reactor. The digital bellow (2) is employed for measuring pressure inside exchanger circuit. The resistance temperature detector (3) is employed to measure temperature in the moderator. The collected data from the sensor are processed and converted into digital data at the locally place Electronic Computing Unit (4) and sent to a dedicated or cloud server (5) via Internet employing and IoT Module (6). The collected data at the Electronic Computing Unit is sent to the dedicated or cloud server as such or even in data chunks corresponding to the size of a hyper-ledger block. The collected sensor data can be broken as data chunks pertaining to hyper-ledger block size in the dedicated or cloud server also. The data chunks are stored in the hyper-ledger Blockchain blocks with the corresponding hash generated. A typical data chunk from the Electronic Computing Unit will consist of the readings from all the three sensors with the corresponding time stamp. The number of set of sensor readings per data chunk loaded onto a block of hyper-ledger Blockchain can be varied. Any form of encryption can also be done on the data chunks before loading them into the blocks of hyper-ledger Blockchain. All these data can be accessed any time in a tamper proof manner from the Blockchain storage system for safety auditing.
