This report contains the text and slide reproductions of a speech on nuclear waste disposal in basalt. The presentation addresses the layout of repository access shafts and subsurface facilities resulting from the conceptual design of a nuclear repository in basalt. The constructibility issues that must be resolved prior to construction are described. (DMC)

Several of the important health and environmental risks associated with a reference geothermal industry that produces 21,000 MW/sub e/ for 30 y (equivalent to 20 x 10/sup 18/ J) are assessed. The analyses of health effects focus on the risks associated with exposure to hydrogen sulfide, particulate sulfate, benzene, mercury, and radon in air and arsenic in water. Results indicate that emissions of hydrogen sulfide are likely to cause odor-related problems in geothermal resources areas, assuming that no pollution controls are employed. For individuals living within an 80 km radius of the geothermal resources, chronic exposure to particulate sulfate could result in between 0 to 95 premature deaths per 10/sup 18/ J of electricity generated. The mean population risk of leukemia from the inhalation of benzene was calculated to be 3 x 10/sup -2/ cases per 10/sup 18/ J. Exposure to elemental mercury in the atmosphere could produce between 0 and 8.2 cases of tremors per 10/sup 18/ J of electricity. Inhalation of radon and its short-lived daughters poses a mean population risk of 4.2 x 10/sup -1/ lung cancers per 10/sup 18/ J. Analysis of skin cancer risk from the ingestion of surface water contaminated with geothermally derived arsenic …

The Dose Equivalent Index (DEI) has been proposed as a dosimetric standard. We have considered the impact of the change on health physics instrumentation measurements and have evaluated the probable errors of representative instruments for measuring the DEI. Little change is found from earlier slab standards. A more important consideration is the appropriateness of the use of the DEI as a dosimetric standard. The DEI may be satisfactory from a conservative viewpoint, but is not necessarily proportional to the true radiological risks involved. An alternate parameter (such as the 1 cm depth dose equivalent for an isotropically irradiated 30 cm sphere as suggested by Kramer) may be more appropriate.

This document is one of a series describing protocols associated with the Livermore Interactive Network Communication System (LINCS) hierarchical architecture. At the heart of LINCS is its basic interprocess communication (LINCS-IPC) service. LINCS-IPC defines a reliable, flow controlled, full duplex, uninterpreted, labeled bit stream communication service. LINCS-IPC is level 4 in the LINCS architecture. Level 3 of LINCS is the Network layer defining an internetwork datagram type service. LINCS-IPC interfaces to User processes that utilize higher level syntactic and semantic conventions for process interaction. The transport service provided by the Delta-t protocol can be considered a sublayer of the LINCS-IPC layer. Delta-t augments the Network level service as required to support LINCS-IPC. This document specifies the services provided by the Delta-t protocol to support LINCS-IPC, the operation of Delta-t, and the services Delta-t requires of the Network level. This document was written to be self-contained but the reader will find it useful to have available for reference the LINCS-IPC and LINCS DeltaGram Network layer protocol specifications. Implementations are underway in Pascal for the PDP-11 running under RT11 and RX11, in BLISS for the VAX running under VMS, in MODEL for the CRAY-1 and CDC 7600 running under NLTSS and LTSS, …

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.
