A device authentication method, an authentication apparatus and a computer-readable storage medium may be provided to authenticate an electronic device. In some implementations, the device authentication method includes: establishing a first connection based on a transparent layer security (TLS) protocol between the electronic device and a first server; sending a first request to the first server to perform identity authentication of the electronic device, the first request being generated on the basis of first information which represents a digital certificate of the electronic device; and on the basis of the first connection, receiving first response information about the first request, the first response information being sent by the first server and carrying a result of the identity authentication of the electronic device performed by the first server.

A main pump shaft seal water injection system of a nuclear power plant includes a jet pump, a high pressure cooler, a hydrocyclone, valves and a main connection pipeline outside of a main pump, and an auxiliary pump and an internal flow path inside the main pump. Inner and outer flow paths of the main pump are connected with a shaft seal water injection hole and a high temperature water drainage hole. The main connection pipeline is connected between an upper filling water pipeline and a shaft seal water injection hole. A bypass pipeline connected with the jet pump, the high pressure cooler and the hydrocyclone, the main connection pipeline is provided with a normally open main pipeline isolating valve. The bypass pipeline allows low temperature upper filling water in the RCV system to enter the shaft seal water injection hole of the main flange directly.
