This report provides an in-depth analysis of the Light-Water Breeder Reactor (LWBR) core installed in the Shippingport Atomic Power Station from 1977 to 1982. The core "was developed to prove the concept of a pressurized water breeder reactor" (iv). Its operation was successful, in that the "LWBR generated more than 29,000 effective full power hours (EFPH) of energy" (1-1). The core's design was based on a Thorium/U-233 fuel cycle. The U-233 isotope was used because of its high neutron regeneration factor ("the average number of neutrons produced in fission for each neutron absorbed in fissile fuel") relative to U-235 and Pu-239 (3-1). The LWBR design was similar to the two earlier PWR core its use of a seed-blanket design for the reactor fuel. However, one difference between the LWBR and the PWR cores that preceded it in the Shippingport plant was the control mechanism: instead of Hafnium control rods, the breeder plant "was designed with a movable seed, which was raised and lowered to control neutron ... Tue, 01 Jan 2002 12:00:00 GMT FY 2003 Naval Reactors budget request. This document provides an extremely detailed analysis of the FY 2003 budget request for the Naval Reactors program. The section on operational lifetimes (page 12 of file) notes that the Enterprise and a number of Los Angeles-class submarines are serving for far longer than their designed lifetimes. The request describes the fact that six of the eight land-based prototypes had been shutdown by 2002 and were in the process of being deactivated. It provides reports on the units within Naval Reactors, including mission goals, recently-completed activities, and planned projects. Tue, 01 Jan 2002 12:00:00 GMT Statement of Admiral Frank L. Bowman, U.S. Navy, Director, Naval Nuclear Propulsion Program to the Senate Armed Services Committee ,Strategic Subcommittee. In this statement, Admiral Frank Bowman provides information to the Senate Armed Services Committee on Naval Reactors' FY 2003 budget request. Bowman describes the composition and strategic capabilities of the Navy's nuclear-powered attack submarines, ballistic missile submarines, and aircraft carriers. He notes that the Virginia-class attack submarines, which are powered by the S9G reactor, have the first cores that are designed to last for the entire lifetime of the ship. Bowman describes the steps being taken to extend the life of nuclear-powered vessels, such as refueling the Los Angeles-class attack submarines. Consistent with the joint Navy-Department of Energy scope of NR activities, Bowman also describes the DOE's budget request, including support for reactor development work that extends core life. He lists Virginia-class (S9G reactor) and CVNX (A1B reactor) development, spent fuel processing, and prototype deactivation as significant DOE funding priorities. Wed, 10 Apr 2002 12:00:00 GMT
