Consequence analysis of a postulated NaOH release from the 2727-W sodium storage facility

Description: Toxicological and radiological consequences were calculated for a maximum sodium fire in the 2727-W Sodium Storage Facility. The sodium is solid and cannot leak out of the tanks. The maximum fire therefore corresponded to the maximum cross-sectional area of one tank. It was shown that release of the entire facility inventory of 22 Na is insufficient to produce an appreciable effect.

Assessment of radiological releases from the NuMI facility during MINOS and NOvA operations

Description: This report makes projections of the radiological releases from the NuMI facility during operations for the MINOS and NO ?A experiments. It includes an estimate of the radionuclide levels released into the atmosphere and the estimated tritium and sodium-22 concentrations in the NuMI sump water and Fermilab pond system. The analysis was performed for NuMI operations with a beam power on target increased from the present 400 kW design up to a possible 1500 kW with future upgrades. The total numbe… more

High energy beam lifetime analysis

Description: We have developed a positron lifetime defect analysis capability based on a 3 MeV electrostatic accelerator. The high energy beam lifetime spectrometer is operational with a 60 mCi {sup 22}Na source providing a current of 7 10{sup 5} positrons per second. Lifetime data are derived from a thin plastic transmission detector providing an implantation time and a BaF{sub 2} detector to determine the annihilation time. Positron lifetime analysis is performed with a 3 MeV positron beam on thick sample… more

Nucleosynthesis and the nova outburst

Description: A nova outburst is the consequence of the accretion of hydrogen rich material onto a white dwarf and it can be considered as the largest hydrogen bomb in the Universe. The fuel is supplied by a secondary star in a close binary system while the strong degeneracy of the massive white dwarf acts to contain the gas during the early stages of the explosion. The containment allows the temperature in the nuclear burning region to exceed 10{sup 8}K under all circumstances. As a result a major fraction … more

Viscous liquid barrier demonstration at the Brookhaven National Laboratory Linac Isotope Producer

Description: Groundwater monitoring has detected tritium ({sup 3}H) and {sup 22}Na contamination down gradient from the Brookhaven LINAC Isotope Producer (BLIP), located at Brookhaven National Laboratory (BNL). Site characterization studies indicate that the BLIP is the source of contamination. The highest measured values for {sup 3}H were 52,400 pCi/L recorded less than 100 feet south (down gradient) of the BLIP facility. The BLIP produces radioisotopes that are crucial in nuclear medicine for both researc… more

Proton resonance spectroscopy. Quarterly technical progress report, December 1992--November 1995

Description: Work on chaos in the low-lying levels of nuclei has continued on several fronts. The major effort has been study of the {sup 29}Si(p,{gamma}) reaction with the goal of establishing a complete level scheme for {sup 30}P and analyzing the eigenvalue fluctuations for evidence of chaos. These measurements are in progress, and the current status is described. A related topic is the search for different signatures of chaos which do not require the extremely high degree of completeness and purity nece… more

Grounding of Beta Sources by an Auxiliary Alpha Source

Description: A Po/sup 210/ source was used to furnish a reliab1e ground for both electron and positron sources. This was done to prevent the electron and positron sources from charging during BETA spectral studies in magnetic lens spectrometers. An approximately 20- mu c Po/sup 210/ source was placed 1.2 in. behind a 4- mu c Na/sup 2 / 2>s positron emitter backed by 20- mu g/cm/sup 2/ Formvar in the spectrometer; this arrangement resulted in a charging rate decrease of approximately 80%. When the source was… more

Solid neon moderated electrostatic or magnetic positron beam

Description: A high intensity variable energy positron beam has been constructed at Brookhaven National Laboratory (BNL). Positrons from a 97mCi {sup 22}Na source are moderated by a thin layer of solid neon. A magnetic guiding system delivered up to 5{times}10{sup 6}e{sup +}/sec to an experiment. Currently tests are under way to facilitate the operation with the magnetic guiding system or -- for other experimental sites -- with an electrostatic beam transport. The electrostatic lenses are fabricated from {m… more

Measurement of proton production cross sections of {sup 10}Be and {sup 26}Al from elements found in lunar rocks

Description: Cosmic rays penetrate the lunar surface and interact with the lunar rocks to produce both radionuclides and stable nuclides. Production depth profiles for long-lived radionuclides produce in lunar rocks are measured using Accelerator Mass Spectrometry (AMS). For a particular radionuclide these production depth profiles can be interpreted to give an estimate for the solar proton flux over a time period characterized by the half life of the radionuclide under study. This analysis is possible if a… more

On the half-life of {sup 44}Ti

Description: One of the few long-lived gamma-ray emitting radioisotopes expected to be produced in substantial quantities during a supernova explosion is {sup 44}Ti. The relevant portions of the decay schemes of {sup 44}Ti and its daughter {sup 44}Sc are shown. {sup 44}Ti decays to {sup 44}Sc emitting {gamma} rays of 68 and 78 keV. {sup 44}Sc subsequently decays with a 3.93-hour half life to {sup 44}Ca emitting an 1,157-keV {gamma}ray. This characteristic 1,157-keV {gamma} ray from the decay of {sup 44}Ti h… more

FISSION PRODUCT YIELDS IN HYBRID (ADS) TARGET MATERIALS INDUCED BY HIGH-ENERGY PROTONS

Description: Fission product cross sections of (p,f)-reaction in thin samples of {sup 208}Pb, {sup nat}HgO, {sup nat}W irradiated with high-energy protons are measured. The irradiations were made using proton beams extracted from the ITEP synchrotron. The nuclide yields were {gamma}-spectrometered directly using a high-resolution Ge-detector. The GENIE2000 code was used to process the measured {gamma}-spectra and the ITEP-developed SIGMA code was used together with the PCNUDAT nuclear decay database to iden… more

Ground-water activation from the upcoming operation of MI40 beam absorber

Description: During the course of normal operation, a particle accelerator can produce radionuclides in the adjacent soil and in the beam line elements through the interactions of accelerated particles and/or secondary particles produced in the beam absorbers, targets, and sometimes elsewhere through routine beam losses. The production and concentration of these radionuclides depends on the beam parameters such as energy, intensity, particle type, and target configuration. The radionuclides produced in the … more

SSCL groundwater model

Description: Activation of groundwater due to accelerator operations has been a consideration since the conceptual stages of the SSC. Prior to site selection, an elementary hydrological model assuming a porous medium with a shallow well in proximity to the tunnel was used to determine the radionuclide concentrations in the water pumped from a well. The model assumed that radionuclides produced within a few feet of the tunnel would migrate to the shallow well and be diluted as the well drew water from a coni… more

Leaching of accelerator-produced radionuclides

Description: Leaching of radionuclides produced in soil and rock by high energy proton-induced radiation was studied for the SCC and CEBAF sites. Comparison was made with predictions of a Monte-Carlo code CASIM and previous results for the Fermilab site. The principal long-lived radionuclides were {sup 3}H and {sup 22}Na in agreement with Fermilab results. A few other radionuclides were present at lower concentrations in a subset of the samples. For example, {sup 134}Cs was detected in a few SSC water sampl… more
