Safe Operation of Nuclear Ships

Experience. The first stage was difficult because of lack of experience in the technical operation of marine nuclear reactors as such, and even more of nuclear-powered ships.

Major conclusions drawn after the first period of trial operation were that nuclear power plant is reliable in operation, provides for easy passing through transient conditions from any power range and gives ice-breakers good manoeuvrability.

The system of a nuclear power guarantees safe charging of power output when energy reactor protection is activated, or when pieces of equipment are out of order.

Biological shielding and other design elements are reliable guards for personnel and environment.

Endurance of 210 days with one charge of fuel was confirmed. At the same time, several shortcomings of the first nuclear steam-generating plant were revealed.

Major equipment had a short service life.

General Directions on Replacement of Faulty Components

Prior to replacing faulty components and adjusting new ones in compliance with the circuit requirements, apart from general acquaintance with the principle of operation and the design of separate components and the unit as a whole, it is required to analyze thoroughly the arrangement of separate parts in the unit, their fastening and accessibility on the sample.

When eliminating the faults detected, the units should be disassembled only in case of actual necessity.

When replacing the faulty components or adjusting the units, it is required to use only the appropriate tools, i. e. all nuts and bolts should be turned out and in by the proper size box spanners or flat keys, and all screws — by screwdrivers corresponding to the sizes of the heads and slits.
