ACTIVITY RELEASE FROM THE N.S. SAVANNAH IN THE MAXIMUM CREDIBLE ACCIDENT

Description: The release of fission products that would occur following the maximum credible accident aboard the N.S. Savannah has been examined. Four significantly different, but realistic, operating histories were considered. The rate of release of noble gases and of iodine isotopes as a function of time after the accident was determined for each operating history and for both normal and emergency reactor-compartment ventilation systems. The influence of radioactive decay and of the time delay in release … more

ULTRASONIC INSPECTION OF A SECTION OF THE NS SAVANNAH PRIMARY PIPING SYSTEM

Description: A section of NS Savannah primary pipe and part of a primary system gate valve were examined ultrasonically to determine whether a fluctuating flow of low- temperature makeup water entering through a nozzle in the valve hsnd damaged the components during service. Examination was prompted by failure of a Vallecitos Boiling Water Reactor (VBWR) recirculating pipe in which makeup water was introduced under conditions similar to those in the Savannah. The ultrasonic equipment was calibrated on spare… more

MARITIME REACTOR PROGRAM. Annual Progress Report for Period Ending November 30, 1962

Description: A survey of the,N. S. Savannah reactor shield was carried out during the report period. The results showed that the shield effectively meets design specifications. Tests of 12 removal by a charcoal unit in the N. S. Savannah reactor emergency ventilation system using 80 to 90% water-saturated air showed a unit efficiency of 99.86 plus or minus 0.07% at the 95% confidence level. Simplified procedures were devised for using shipboard equipment to screen personnel suspected of having body burdens … more

NEUTRON PHYSICS DIVISION ANNUAL PROGRESS REPORT. Period Ending September 1, 1962

Description: A total of 74 subsections are included in the report. The information in 4 subsections was previously abstracted in NSA. Separate abstracts were prepared for 38 of the subsections. Those sections for which no abstracts were prepared contain information on prompt neutron lifetime, Rover critical experiments, Pu/sup 239/ fission, neutron decay, the O5R code, alpha scattering, 8 and P wavelengths, proton scattering, deuteron scattering, local optical potentials, N. S. Savamah radiation leakage, re… more

Study of Core Cooling Requirements During NS Savannah Refueling

Description: The requirements for cooling the NS Savannah reactor core during refueling were investigated. The two-part study included analysis of the system required to provide coolant flow to the reactor and to remove the decay heat generated and analysis of flow and temperature characteristics in the reactor during refueling. Since previous investigations of the system requirements were made, this study was concerned primarily with the flow and temperature analysis. (auth)

An Evaluation of the Substitution of Zircaloy for Stainless Steel in n.s. Savannah Fuel-Element Containers. Summary Report

Description: The possibility of reducing fuel-cycle costs for the N.S. SAVANNAH by replacing the stainless steel fuelelement containers in the permanent reactor core structure by similar containers of a zirconium alloy was investigated. These containers, although not integral parts of the fuel-bearing components, are located within the active core and divide the core into 32 separate channels into which the fuel elements are placed. Areas of investigation included reactor physics, fuel-cycle economics, mate… more
