Abstract
In nuclear power plants, plant management systems are not only very important for operation and maintenance of the facilities, but also play a very important role in analyzing and reporting the events to the authorities when a failure or accident occurs in the facility. In addition, it is also important to ensure that event records are managed transparently so as not to cause any attempt to cover up events. Therefore, this paper proposes a tamper free plant operation system by applying blockchain technology to the integrated plant management system of Korea hydro and nuclear power (KHNP). As a result, this paper will contribute to improving public acceptance by eliminating distrust in safe operation of nuclear power plants.
Highlights
Power generation facilities are becoming more and more automated, thereby increasing the use of computer hardware and software
Information 2020, 11, 282 purpose of this paper is to propose the application of blockchain technology to plant management system (PMS) as a way to solve such problems
The nuclear safety and control act (NSCA) and regulations, as well as other record-keeping and reporting requirements (CNSC document S-99, operational requirements for nuclear power plants), ask to provide sufficient information to ensure that the maintenance program is fully operational and objective evidence is presented under the quality assurance program [8]
Summary
Power generation facilities are becoming more and more automated, thereby increasing the use of computer hardware and software. A plant management system (PMS) is used for database operation and information management of facilities to support productivity improvement and efficient management of plant facilities, as well as job management, personnel management, and radiological control. Advancement in computer communication technologies makes it possible for utilities to consolidate computer resources and increase the availability of information, and helps them operate their plants more efficiently. Blockchain has some unique properties which include immutability, non-repudiation, data integrity, transparency and equal rights. It has its limitations as well, such as privacy and scalability. Application examples include, but are not limited to, digital currency, international payments, securities registration and settlements from the financial sector, registries, identity and taxation as government services, the internet of things (IoT) storage, and information management and supply chains from industry. Chains are a highly promising area for the application of blockchain [2,3,4]
