Prevention of biofouling on heat transfer surfaces of ocean thermal energy converters. Progress report, May 1, 1975--November 30, 1975 (open access)

Prevention of biofouling on heat transfer surfaces of ocean thermal energy converters. Progress report, May 1, 1975--November 30, 1975

The objectives of the program were to develop chemical processes utilizing a combination of certain fluorochemicals and tribulyltin based toxicants for treating the surfaces of metals which may be used to fabricate OTEC heat exchangers, and to demonstrate the effectiveness of these surface treatments as antibiofoulants. Aluminium alloy No. 3003-H14 and titanium were testd, neither of which proved satisfactory. (WDM)

Correlation of mechanical and metallurgical parameters with the acoustic emission during tensile deformation of several metals and alloys (open access)

Correlation of mechanical and metallurgical parameters with the acoustic emission during tensile deformation of several metals and alloys

Acoustic emission was monitored during plastic deformation under dead-weight tensile loading of polycrystalline aluminum, brass, copper, and steel. The acoustic emission data, both threshold-type and frequency-analysis type, were correlated with yield strength, stored elastic energy, strain hardening parameters, loading histories, diffusion processes, slip band motion and mosaic cell size. Major results are presented under the headings discontinuous yielding (Portevin--Le Chatelier Effect), parabolic strain hardening, and frequency analysis. The principal experimental techniques are also summarized. (auth)

Studies of encapsulant materials for terrestrial solar-cell arrays. First quarterly progress report, October 9--December 9, 1975 (open access)

Studies of encapsulant materials for terrestrial solar-cell arrays. First quarterly progress report, October 9--December 9, 1975

Study 1 of this contract is entitled ''Evaluation of World Experience and Properties of Materials for Encapsulation of Terrestrial Solar-Cell Arrays.'' The approach of this study is to review and analyze world experience and to compile data on properties of encapsulants for photovoltaic cells and for related applications. The objective of the effort is to recommend candidate materials and processes for encapsulating terrestrial photovoltaic arrays at low cost for a service life greater than 20 years. The objectives of Study 2, ''Definition of Encapsulant Service Environments and Test Conditions,'' are to develop the climatic/environmental data required to define the frequency and duration of detrimental environmental conditions in a 20-year array lifetime and to develop a corresponding test schedule for encapsulant systems.

Compilation of TFTR materials data (open access)

Compilation of TFTR materials data

In order to document the key thermophysical property data used in the conceptual design of Tokamak Fusion Test Reactor (TFTR) systems and components, a series of data packages has been prepared. It is expected that data for additional materials will be added and the information already provided will be updated to provide a project-wide data base.

Sequence of operations: TFTR assembly and disassembly

A conceptual sequence of operations necessary to complete initial assembly of the Tokamak Fusion Test Reactor (TFTR) are described along with subsequent disassembly operations and special techniques planned for use during radioactive disassembly. Special attention is given in this report to techniques, personnel exposure, and equipment needed to effect the opening and closing of a vacuum vessel port and the installation of the vacuum vessel seal weld cutting machine under radioactive conditions.
