 Chapter title:  "Reactor physics and its application to nuclear power reactors" 
 Summary:  This chapter, written by physicist Alvin Radkowsky, summarizes the design challenges of submarine reactors in comparison with the natural uranium graphite reactors that had been designed and built during World War II. For example, Radkowsky describes the novelty ("close spacing") and design complexity of the control rod arrangement in PWRs (4). He also describes the parallel track of reactor development overseen by NR, with the intermediate range research supporting the S1G and S2G reactors performed by the Knolls Atomic Power Laboratory; and, research supporting the Submarine Thermal Reactor (STR, or the S1W and S2W reactors) led by the Bettis Atomic Power Laboratory. He notes that while the intermediate range reactor approach had, by 1964, been abandoned in favor of the pressurized water reactor (PWR) design, that "fuel loading densities are often sufficiently high [so] that a substantial fraction of the fissions occurs above thermal neutron energies" (2). As a result, some research relating to the intermediate range reactor could be applied to the design of PWRs. Radkowsky also summarizes some design contrasts between submarine reactors and the reactors for the Shippingport Atomic Power Station, with the latter relying on fuels with high U-238 composition.
