Independent safety evaluation of the enriched uranium oxide test UO-1

The UO-1 test is designed to provide information on the performance of D9 clad, enriched uranium oxide fuel in FFTF. The Series IV FFTF driver fuel will utilize enriched uranium oxide fuel with D9 cladding. Irradiation data are needed for computer code calibration to support the FSAR analysis effort for the series IV fuel. The UO-1 assembly consists of a 217-pin bundle with the same pin and duct dimensions as a standard driver fuel assembly. The test consists of seven UO{sub 2} pins, 30 mixed oxide test pins, and 180 driver type pins. The test will be irradiated for approximately 250 EFPD. An Independent Safety Evaluation (ISE) of the test has been conducted. Information has been taken from the Test Design Documents, but independent calculations have been made of the safety-related parameters. The scope includes all items specified in the Users` Guide for Irradiation of Experiments in the FTR. Areas investigated include Technical Specification Compliance, Steady State Operation, Transient Operation, Failure Consequences, Stress and Seismic, HCDA, and Test Handling and Criticality Considerations

Accident consequence calculations for project W-058 safetyanalysis

Accident consequence analyses have been performed for Project W-058, the Replacement Cross Site Transfer System. using the assumption and analysis techniques developed for the Tank Remediation Waste system Basis for Interim Operation. most potential accident involving the FISTS are bounded by the TWRS BIO analysis. However, the spray leak and pool leak scenarios require revised analyses since the RCSTS design utilizes larger diameter pipe and higher pressures than those analyzed in the TWRS BIO. Also the volume of diversion box and vent station are larger than that assumed for the valve pits in the TWRS BIO, which effects results of sprays or spills into the pits. the revised analysis for the spray leak is presented in Section 2, for the above ground spill in Section 3, for the presented in Section 2, for the above ground spill in Section 3, for the subsurface spill forming a pool in Section 4, and for the subsurface pool remaining subsurface in Section 5. The conclusion from these sections are summarized below

Comparison of radiological dose pathways for tank farm accidents

This calculation note documents an evaluation of the doses from submersion and ground shine due to a release of tank farm radioactive materials, and a comparison of these doses to the doses from inhalation of the materials. The submersion and ground shine doses are insignificant compared to the inhalation doses. The doses from resuspension are also shown to be negligible for the tank farm analysis conditions

Looking for Matthew: The Effects of Private Tutoring on the Educational Outcomes of Fourth Grade Public School Students in Cambodia

Using the World Bank Public Expenditure Tracking Survey (PETS) 2004 data, propensity score matching is utilized to infer a causal impact of private tutoring on the numeracy, literacy, and total outcomes for fourth grade public school students. This research finds that students who self-report that they participate in private tutoring everyday as compared to their peers who never participate in private tutoring scored higher in literacy, numeracy, and total scores. A small Matthew Effect was found as the statistically significant variables used as predictors aligned with socio-economic status. This alignment depicts that the rich become academically richer while the poor become academically poorer. The hybrid public-private education system in Cambodia may be exacerbating inequity for the most marginalized populations

The history of the development of the large round bale

The University Archives has determined that this item is of continuing value to OSU's history.Researchers at the Ohio Agricultural Research and Development Center (OARDC) can be credited with introducing the concept of the large round bale to the United States and for conducting the first research on the bale in this country. This introduction and subsequent research, together with development by farm equipment companies, led to the large round balers that are now in common use. The large round hay baler has revolutionized the harvesting, handling, storage, and feeding of hay. This technology has spread throughout the United States and the world. It has been the major development in haying during the past several decades

Modular Measurement in 1971

Van Keuren is concerned with making all building components fit each other so that they can be joined at the site of construction with a minimum of cutting and fitting, as well as making it possible to dimension all building plans to incorporate materials conforming to the discussed modular measure
