The CSMP proposal to NSF contained a description of a project to examine variability of the climate system on decadal-to-contennial time scales, with an emphasis on eventually understanding the processes which led to climate variability over the past one to two centuries as a basis for validating models of potential future changes. The project thus focused first, on understanding, and second on understanding as a basis for the development of validation procedures for models intended for use in climate change applications. The principal activity of the first year of the project was a workshop on one of the major sources of interdecadal variability-the thermohaline circulation (THC) of the oceans. This workshop was focused on review of the cutting edge science of the THC, and on identification of opportunities for future research. The workshop report is attached.

The Part B Permit for F&H Seepage Basins calls for analysis of several constituents of concern in groundwater monitoring wells. Four of these analytes are the radionuclides Ni{sup 63}, Pu{sup 241}, Pu{sup 242}, and Am{sup 243}. These are currently not being analyzed due to their very difficult, tedious analytical schemes coupled with their relatively low activity values. This report demonstrates how the activity value for Ni{sup 63}, a week beta emitter, can be estimated from that of Co{sup 60}, an easily detectable, high-energy gamma emitter. Similarly, estimates of Pu{sup 241}, a beta emitter, and the alpha-emitting Pu{sup 242} can be made from the activity value of the more easily detected Pu{sup 239}. Am{sup 243} can be estimated from the activity of Cm{sup 244}, which is easier to detect because of a shorter half-life (higher specific activity) and the emission of higher energy alpha particles. These correlations are made under very specific parameters in order to ensure the validity of this approach. Therefore, assumptions must be established setting ground rules for establishing these activity relationships. Bases for these assumptions are explained and/or referenced. Their degree of uncertainty limits the accuracy of the data so that the term ``estimate`` is used. Such …

The Alternating Gradient Synchrotron Booster at Brookhaven National Laboratory uses an ionization profile monitor to generate profiles of proton and heavy-ion beams. The profile monitor can acquire hundreds of profiles during an acceleration cycle, and then display and store them for analysis. Profiles appear in real time on an oscilloscope-type display, but other visualizations are available as well, namely mountain range and emittance displays. File storage of profile data is simple, as is the storage of moments and emittances.

Representatives of nearly one-half of the 114 member states of the International Atomic Energy Agency (IAEA), including the United States, have participated in the development of an international nuclear safety conventions proposed multilateral treaty to improve civil nuclear power reactor safety. A preliminary draft of the convention has been developed (referred to as the draft convention for this report), but discussions are continuing, and when the final convention text will be completed and presented to IAEA member states for signature is uncertain. This report responds to the former and current Chairman`s request that we provide information on the development of the nuclear safety convention, including a discussion of (1) the draft convention`s scope and objectives, (2) how the convention will be implemented and monitored, (3) the views of selected country representatives on what provisions should be included in the draft convention, and (4) the convention`s potential benefits and limitations.

Weekly newsletter discussing natural resources, parks, hunting and fishing, and other information related to the outdoors in Texas.

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.
