Assessment of a small pressurized water reactor for industrial energy

Description: An evaluation of several recent ERDA/ORNL sponsored studies on the application of a small, 365 MW(t) pressurized water reactor for industrial energy is presented. Preliminary studies have investigated technical and reliability requirements; costs for nuclear and fossil based steam were compared, including consideration of economic inflation and financing methods. For base-load industrial steam production, small reactors appear economically attractive relative to coal fired boilers that use coal… more

Potassium vapor topping cycle. Technical progress report, April 1--June 30, 1977

Description: The potassium vapor topping cycle is a concept for increasing the efficiency of the Rankine vapor cycle by raising the peak temperature by employing a potassium vapor cycle with a turbine inlet temperature of 1500 to 1600/sup 0/F (815 to 870/sup 0/C) in which the waste heat rejected from the condensing potassium vapor is transferred to boiling water and steam in a conventional steam cycle. An efficiency of about 50% is calculated for this cycle with a natural circulation potassium boiler fired … more

Evaluation of regional effects of effluents from uranium production in New Mexico

Description: The Grants Uranium Region is a 2500 mile area of northcentral New Mexico which has produced about 40 percent of all domestic uranium, and holds over one-half of the current reserves. The increasing demand for uranium to fuel commercial nuclear power plants is resulting in rapid growth of the uranium industry and economic, social, and environmental changes are occurring. One of the environmental issues of this region is the concern for eventually unacceptable levels of air and water pollution fr… more

Stress analysis of cylindrical pressure vessels with closely spaced nozzles by the finite-element method. Volume 1. Stress analysis of vessels with two closely spaced nozzles under internal pressure. [BWR; PWR; MULT-NOZZLE code]

Description: A finite-element computer program, MULT-NOZZLE, was developed for the stress analysis of cylindrical pressure vessels with two or three closely spaced reinforced nozzles. MULT-NOZZLE consists of two modules which may be operated independently. The first module, FEMG, automatically prepares a finite-element mesh including the nodal point coordinates, finite-element connectivities, mesh options, and boundary value specifications for input to the finite-element solution module SAP3M. SAP3M, which … more

Discussion of heat mirror film: performance, production process, and cost estimates

Description: Intrex film is a unique, transparent, electrically conductive plastic film originally developed as a component in electrically heatable, transparent products such as de-icing windshields for aircraft, locomotives, and the like. The electrical conductivity is imparted to the plastic film by the vacuum deposition of a thin film of gold onto one surface. This gold film exhibits typical luminous transmittance of 80% and sheet resistivity of 10 ohms per square. The free electron concentration in the… more

Review of cooling tower drift deposition models

Description: The behavior, basic assumptions, and limitations of ten different models for calculating the drift deposition rate from wet cooling towers are reviewed and then their predicted results for such deposition with a common set of input parameters are compared. The predicted maximum deposition differs among the models by two orders of magnitude with a wide range in peak location. Comments and suggestions to improve the models are included.

Review of electron-beam welding studies utilizing x-ray spectroscopy

Description: A review is presented of results obtained using an X-ray spectroscopy technique to study the electron-beam welding process. Results show that the technique is well suited for this kind of study. In particular, accurate voltage control is possible, and such control reduces weld-penetration variations significantly. Analytical techniques developed for studying noise on electron beams have general applicability for signal analysis. The work also shows that no voltage or current pulses were seen, a… more

Prestressed concrete reactor vessel thermal cylinder model study

Description: The thermal cylinder experiment was designed both to provide information for evaluating the capability of analytical methods to predict the time-dependent stress-strain behavior of a /sup 1///sub 6/-scale model of the barrel section of a single-cavity prestressed concrete reactor vessel and to demonstrate the structural behavior under design and off-design thermal conditions. The model was a thick-walled cylinder having a height of 1.22 m, a thickness of 0.46 m, and an outer diameter of 2.06 m.… more

Local sodium boiling in a partially blocked simulated LMFBR subassembly (THORS Bundle 3B)

Description: Experimental data from local sodium boiling tests with and without argon gas injection have been analyzed. The experiments were conducted with a 19-rod simulated LMFBR subassembly having the six central flow channels (12% of flow area) blocked in the heated section of the bundle. The data analysis shows that, without gas injection, local boiling in the blockage wake does not radially propagate to the surrounding free stream during two quasi-steady-state boiling periods of 13 and 27 sec. However… more

Corrosivity of solutions from evaporation of radioactive liquid wastes. Final report

Description: New double-shell storage tanks are constructed with ASTM A-516 Grade 65 steel. This study had two main objectives: To characterize the corrosivity of synthetic nonradioactive terminal waste solutions to ASTM A-516 Grade 65 steel and to determine the severity of stress-corrosion cracking of carbon steel in terminal waste solutions. The information developed provides guidance in the characterization of the aggressiveness of actual terminal liquors and in the design and operation of fail-safe tank… more
