Biological fate of cobalt-60 released during the corrosion of neutron-activated stanless steel in seawater

Description: Passing seawater over radioactive Type 347 stainless steel in a sediment/seawater laboratory system and exposing marine animals to this environment provided information on the bioaccumulation of /sup 60/Co from radioactive structural material. Exposure of marine organisms to radioactive corrosion products and directly to radioactive stainless steel in seawater simulated some of the possible conditions which could arise from the deposition of radioactive stainless steel on the ocean floor. Detec… more

Bioaccumulation and food chain transfer of corrosion products from radioactive stainless steel

Description: Two sets of experiments were conducted to determine if corrosion products from radioactive Type 347 stainless steel could be biologically transferred from sediment through a marine food chain, and whether corrosion products dissolved in seawater could be bioaccumulated and then eliminated. Corrosion products containing /sup 60/Co and /sup 63/Ni from the radioactive stainless steel were introduced into marine sediments. Infaunal polychaete worms exposed to these sediments bioaccumulated the radi… more

Siting commercial fusion power plants

Description: This document discusses siting requirements for fusion power plants. The current concept of the reference first commercial reactors was developed from analysis of the characteristics of current design concepts. Because those reactors use the deuterium-tritium fuel reaction, large quantities of activation products and tritium are created and must be considered as potential sources of radiation doses (Young, 1976 and Young and Gore, 1976). However, advanced reactors using fuel reactions that neit… more

Description: Standard procedures for estimating capital and operating costs for the Environmental Control Technology Project are presented in this report. Two different procedures were used for estimating capital costs: (1) general order-of-magnitude estimates for those facilities which are invariant among environmental control technologies, and (2) detailed estimating procedures for those facilities and control systems expected to vary among comparisons of environmental control methods. The general approac… more

ADVANCED DESIGNS OF MAGNETIC JACK-TYPE CONTROL ROD DRIVE

Description: The magnetic jack is a device for positioning the control rods In a nuclear reactor, especially in a reactor containing water under pressure.

Reconnaissance of intertidal and subtidal zones of Back Island, Behm Canal, Southeast Alaska

Description: A diver reconnaissance of the intertidal and subtidal zones of Back Island, Southeast Alaska, was performed May 20-22, 1986. The specific objectives were to catalog potentially vulnerable shellfish, other invertebrates, and plant resources, and to identify potential herring spawning sites. This effort was designed to supplement the existing ecological data base for Back Island that would be used during the National Environmental Policy Act (NEPA) documentation process. A NEPA document will be p… more

Studies on production of metastable core-excited atoms by laser-produced x-rays. Final report, 1 October 1984-30 September 1985

Description: The overall objective of the work on this program was to study methods for production of core-excited metastable atoms by laser-generated x-rays. We are interested in the spectroscopy of these levels, their autoionizing and radiative rates, and their metastability in the presence of hot electrons and ions. The concept of using x-rays emitted from a laser-produced plasma to excite large densities of energetic excited levels in atoms and ions has been thoroughly experimentally investigated using … more

ECUT energy data reference series: ammonia synthesis energy-use and capital stock information

Description: Energy requirements for ammonia synthesis totaled 0.55 quadrillion Btu of natural gas in 1980 and 28,500 MMBtu (8.3 x 10/sup 6/ kWh) of electricity. Efficiencies ranged from 0.72 to 0.8 for natural gas and 0.65 for electricity. Ammonia production in 1980 is estimated at 21 million tones. In the year 2000, U.S. ammonia production is estimated to be between 27 to 34 million tones with 19 to 31 million tons being produced using natural gas. A most likely value of 25 million tons of ammonia from na… more

Reference commercial fusion power plants

Description: Currently available conceptual designs for commercial fusion power plants are for first generation plants using deuterium-tritium (D-T) fuel, and are all functionally similar. This similarity has been used as a basis for defining an envelope of D-T fusion power plant characteristics which encompasses the characteristics of the available designs. A description of this envelope, including general process descriptions, proposed materials uses and a tabulation of numerical ranges of plant parameter… more

Thermal shock tolerances of six fishes and one invertebrate from the Pacific Northwest

Description: The purpose of this study was to ascertain the temperatures at which selected estuarine fishes from the Pacific Northwest and one of their potential food organisms would be incapacitated and killed after entering the thermal plume of an industrial cooling system. This information aids in impact evaluation of thermal discharges, especially where they act as barriers or entrapments. Data are presented from laboratory studies of equilibrium loss and thermal death as endpoints for different rates o… more

Effect of 6.6 pH process water on process tube and fuel element corrosion

Description: Reduction of the reactor process water pH from 6.9 to 6.6 at 100-B, D, DR, KF, and H currently is proposed in order to reduce the aluminum corrosion rate and the resultant outage time for water leaks, fuel ruptures, and process tube replacement. This document reviews the current knowledge of the effect of reducing the pH to 6.6 on aluminum corrosion. An estimate of the expected costs and benefits is included.

Forecast reactor water leaks

Description: Reactor water leaks cause outage time for locating and eliminating the leaks and for repairing damage paused by the vater that enters the reactor. The justification for equipment and process changes necessary for reducing the number of leaks and the resultant outage time is dependent on the number of leaks expected. This document presents an estimate of the future reactor water leak frequency and the average outage time charged to each leak. A water leak is defined as any entry of vater into th… more

Carbon dioxide for pH adjustment 100-K Reactors

Description: This report presents the results of a recent analysis to determine if there is a practical method for using carbon dioxide for pH adjustment at the 100-K Reactors. Carbon dioxide could be recovered from the boiler stack gas and introduced into the K Reactor process water. The approximately $240,000 installation cost would be repaid in about one year by the reduction of sulfuric acid costs. The proposed system would consist of a blower, a purification system, and a distribution system for conduc… more

Tube Wall Thickness Isotope Production Tubes

Description: Irradiation of process tubes containing appropriate parent materials has been proposed by Manufacturing as a method for obtaining new products from the Hanford Reactors. The process tubes would be removed at appropriate intervals and shipped to separations plants for recovery of the products. The tube residence in the reactor could be determined by the optimum irradiation period for isotope production rather than by the period required to corrode tubes of current design to the minimum permissib… more
