This brief topical report, provides information on a comparison of the mouse micronucleus mutagenic test proposed by a DOE contractor (FMC) for coal derived chemicals; as compared with the in vivo cytogenic test. The latter procedure is repotedly preferred by EPA authorities connected with implementation of the toxic substances control act (TOSCA). This evaluation was performed at the request of Headquarters DOE program management staff. The mouse micronucleus test takes less time and costs approximately one-fourth that of the in vivo cytogenetic procedure. This topical report is written to the extent possible in non-technical language to present conclusions associated with the evaluation rather than a detailed scientific dissertation.

A brief overview is presented of potential uses for rf heating of plasmas in mirror devices. While some discussion relating to past experiments is given, the main emphasis is devoted to a review of potential experiments in presently existing devices, and devices under construction or planning. Some predictions are made for plasmas in mirror reactors.

Measurements of n/sub 2/ for a large class of oxide and fluoride crystals and glasses have been made using 100-ps, 1.06-..mu..m laser pulses and time-resolved interferometry. Values of n/sub 2/ for various glasses are summarized.

The study focuses on improving the load modeling technique of Seasonal Performance Model (SPM) in order to estimate a more realistic load for seasonal analysis calculations on an hourly basis. A computer simulation program, Seasonal Performance Model Load (SPMLD), was used to calculate the cooling and heating loads for a typical residence in Caribou, Maine; Columbia, Missouri; and Fort Worth, Texas. The derivation of the SPMLD is described and changes made to improve cooling and heating load estimates are identified. (MCW)

The FY 1980 effort was to investigate four technology options identified by program participants as potentially viable candidates for near-term demonstration: the Gas Turbine system (HTGR-GT), reflecting its perceived compatibility with the dry-cooling market, two systems addressing the process heat market, the Reforming (HTGR-R) and Steam Cycle (HTGR-SC) systems, and a more developmental reactor system, The Nuclear Heat Source Demonstration Reactor (NHSDR), which was to serve as a basis for both the HTGR-GT and HTGR-R systems as well as the further potential for developing advanced applications such as steam-coal gasification and water splitting.

A process-oriented approach is described for encouraging community level energy conservation and planning programs. The approach is designed to augment existing energy programs by focusing on the major barriers to changing current energy-related behavior and attitudes. A variety of concepts, tools and techniques which can be used to overcome these barriers are described. Suggestions are offered on how to design community energy campaign based on the concepts, tools and techniques described. Some brief case studies are provided as examples. (LEW)

The Preamble of the Certification/Enforcement of the DOE Energy Efficiency Standards is presented. Definitions of certification and enforcement are first presented. Additional parts are: Major Certification/Enforcement Approaches Considered; Proposed Certification/Enforcement Approach; Sample Plan for Certification and Enforcement Testing; Estimated Manufacturer Test Costs Under the Proposed Approach; and Additional Certification/Enforcement Issues (relationship between DOE Enforcement of Standards and Industry Trade Association Programs; test variability among different test facilities; small-manufacturer concerns). Complete procedures of the Certification/Enforcement Program are given. Important information given in the appendices are: sampling-plan requirements for certification and enforcement testing; required information and format for the certification report, conditional certification report, and post-certification report; required information and format for the pre-certification report; minimum information to be retained by the manufacturer on energy-efficiency test facilities and instrumentation; and list of minimum supporting certification test data to be retained by the manufacturer.

Four topics are discussed in this report: the feasibility of applying ion cyclotron resonance heating (ICRH) in the TMX central cell, some applications of heating, the results of preliminary experiments, and plans for further ICRH experiments.

Separate abstracts were prepared for the two papers included in this report. (MHR)

During the first quarter, preliminary testing demonstrated the ability of ultrasonically enhanced comminution to increase fraction of -200 mesh particles by 100 to 500% over mechanical grinding alone. Modification of the preliminary ultrasonic comminution process to include cycles of ultrasonic activation followed by removal of fines has shown a significant increase in the production of -325 mesh particles (-44 microns) with substantial fractions in the -20 micron and -10 micron ranges. Efforts to characterize coal samples have yielded a correlation between Hardgrove Grindability Index (HGI) and susceptibility to ultrasonic comminution. This information, along with other considerations and data relating to the cost effectiveness of industrial ultrasonic comminution, will be used to select coal samples for the Phase II experiments. While several preliminary equipment configurations have been used, their purpose has been mainly to verify the mechanism of ultrasonic comminution and to secure information for the design and fabrication of optimized laboratory apparatus for Phase II testing. On this basis a nip configuration has been selected to insure contact throughout the ultrasonic activation period and prevent coal particle compaction.
