CVX: Propulsion System Decision. Industrial Base Implications of Nuclear and Non-Nuclear Options


Book Description

The U.S. Navy is currently in the process of designing its next generation aircraft carrier, termed CVX. One technological advance for the CVX, compared with the current Nimitz class of carriers, is a new propulsion system. To help in deciding between a nuclear and non-nuclear propulsion system for CVX, the Navy asked RAND to determine the effects of the CVX propulsion choice on the industrial bases supporting nuclear propulsion systems and those supporting conventional propulsion systems. RAND began the research in April 1998 and, because of the time frame of the CVX propulsion system decision, provided the results of the analyses to the CVX program office in August 1998. Shortly thereafter, the decision was made that the CVX class would use nuclear propulsion. The research findings described in this document helped influence that decision. This document offers the briefing presented to the program office along with accompanying annotation. The research was based on understanding the various propulsion system options being considered and contacts with suppliers and integrators of key system components to establish how a CVX decision would affect their company and their industry, as well as other Navy programs. This research and its documentation should be of interest to the Office of the Secretary of Defense (OSD) and Navy policymakers and planners who must face the propulsion system decisions for future Navy ship programs. It may also interest industrial decisionmakers involved in construction and supply of Navy ships and parts.

Modernizing the U.S. Aircraft Carrier Fleet


Book Description

The U.S. Navy is currently designing the next generation aircraft carrier, the CVN 21. This class of carriers will use the same basic hull form as the current Nimitz class but will include a substantial redesign of the interior of the ship for improved weapons handling and stores management functions. It will also incorporate several new technologies including a new propulsion system and new aircraft launch and recovery systems. These improvements not only will increase the operational capability of the ship but also are anticipated to lower the ship's manpower requirements and maintenance costs. Under current force modernization plans, new ships of the CVN 21 class will be introduced every four or five years as the ships of the Nimitz class reach the end of their planned 50-year operational life. Under this strategy, Nimitz class carriers will be operating for over 50 more years and it will take decades to transform the aircraft carrier fleet to ships of the new class.On the basis of some preliminary calculations that appeared promising, RAND proposed to the Program Executive Office (PEO) for Aircraft Carriers an examination of a way to accelerate the transformation of the carrier force: replacing Nimitz-class carriers as they reach mid-life instead of refueling them. In this report we identify specific fleet management options for building new instead of refueling, and we evaluate their advantages and disadvantages. This report should be of interest to Navy and Office of Secretary of Defense planners examining fleet modernization options, especially those organizations addressing the costs of alternative force structure options.

Economics of Nuclear Power


Book Description

This book is a unique introduction to the economic costs of nuclear power. It examines the future of the nuclear power industry and unpacks the complicated relationships between its technical, economic and political variables. It does so by modelling the costs, risks and uncertainties of one of the world’s most opaque industries using micro-econometrics, econometrics, and cost engineering. Economics of Nuclear Power examines the very important costs of externalities (storing of nuclear waste and the impact of a Chernobyl or Fukushima event) and compares those to the externalities of alternative carbon based energies (oil, coal, natural gas). With over 100 tables and figures this book details nuclear power production around the world - present and planned, providing a completely global focus. It also includes an overview of the past 70 years of international nuclear power developments. This book is essential reading for students, scholars and professionals interested in energy economics, nuclear engineering and energy policy.
