Combatant Ship Engineering, A Different Approach

ABSTRACTAt present spent nuclear cores from Alfa class submarines are being stored in temporary facilities, designed to sore them only for a few years (3 to 5 years). This paper assesses the problems of nuclear safety during long-term unplanned forced storage of spent fuel because of the delay in building permanent facilities. The Nuclear Submarines (NS) cores use heavy liquid metal lead-bismuth coolant in the primary circuit of nuclear reactor. The radiation parameters of the discharged cores from NS of the Project 705K (this is the number of ship engineering design) are determined. Based on that determination a step-by-step solution is proposed and the technological and other challenges that the Project faces are considered.

Ship Engineering

For several years the Navy has been systematically analyzing problems with its ship engineering and improving its organization and processes for ship engineering. This paper briefly discusses the Navy organization for ship engineering and some of the major initiatives to improve ship engineering. These initiatives have led to an expanded role for the planning yard in supporting, maintaining, and modernizing Navy ships. The paper focuses on the two primary functions of the planning yard: ship alteration engineering and ship configuration identification.

A statistical method for the identification of nonlinear random vibration systems is presented. The first step in the identification process is to obtain a discrete time version of a random vibration model using a local linearization approach. It is shown that the discrete time version thus obtained may be utilized in the identification of original random vibration model. The method is applied to some real ship engineering data.
