A megachannel pulse-height analysis system using a PDP-8/E computer and two moving-head disk memories has been developed. The system has a storage capacity of 220 memory locations, is capable of processing 1100 events/s, and provides on-line sorting and disk storage. An X- or Y-pulse-height spectrum in coincidence with one or several arbitrary pulse-height windows can be assembled in core for scope display and spectral analysis within 2 to 20 seconds. Reconstruction of a complete X- or Y-pulse-height spectrum requires about 3 minutes.

Low-resolution field ionization and high-resolution 70-eV electron-impact mass spectra data were obtained for 28 GPC fractions acquired from Bartlett, Kansas, heavy petroleum by members of the Separation and Characterization group at the Bartlesville Energy Research Center. This group was supplied with most-probable empirical formulas deduced from the high resolution electron-impact data. Analysis of the qualitative and quantitative analytical data previously obtained for GPC fractions from a Synthoil sample by high- and low-resolution field-ionization and high-resolution 70-eV electron-impact mass spectrometry is essentially complete. A study of field-ionization sensitivities for saturates and mixtures of saturates and aromatics is in progress. Components required to modify the combined FI/EI ion source to permit operation in the field desorption mode have been ordered.

As a result of an explosion in the Waste Treatment Facility, 242-Z Building, 200 West Area of the Hanford Reservation on August 30, 1976, the Manager of the Richland Operations Office (RL), Energy Research and Development Administration (ERDA), appointed an ERDA Committee to conduct a formal investigation and to prepare a report on their findings of this occurrence. The Committee was instructed to conduct the investigation in accordance with ERDAMC 0502, insofar as circumstances would permit, to cover and explain technical elements of the casual sequence(s) of the occurrence, and to describe management systems which should have or could have prevented the occurrence. This report is the result of the investigation and presents the conclusions of the review.

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 Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents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.
