Leaching and Precipitation Tests on Grants Ores
Leaching tests were run on two samples from the Grants area in New Mexico. Uranium extractions of 94 per cent were obtained by leaching Sample 6-1 with solutions containing 240 lbs. of Na2CO3 and 60 lbs. of NaHCO3 per ton and by leaching Sample 6-2 with 270 lbs. of Na2CO3 and 180 lbs. of NaHCO3 per ton. Cyclic tests were completed using caustic precipitation of the leach liquor.

Energy Spectrum of Deuterons Stripped From He3 and the Resultant Neutron Yield
The attenuation curve of the deuterons stripped from He3 has been measured with a Faraday cup. The corresponding curve at 190 Mev was fit by assuming that the deuterons were monoenergetic, with three processes taking place.

Feed Water Heater.
Patent for a new and improved feed water heater. This design "provide[s] a system of levers and a float which will automatically regulate the feed or supply of water to such heaters and lime-extractors . . . and further, that by securing a uniform supply of water the steam acts more equally upon the water, and thus secures a more uniform deposit of the lime" (lines 22-33). This allows for fewer accidents and less damage to the engine.

European Union Enlargement
On May 1, 2004, 10 states joined the European Union (EU), enlarging the Union to 25 members. The EU views the enlargement process as an historic opportunity to promote stability in Europe and further the integration of the continent by peaceful means. In addition to the 10 new members (Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia), three other states — Bulgaria, Romania, and Croatia — hope to accede to the EU by 2007. Turkey is also a candidate and is expected to begin accession negotiations in 2005. Macedonia has also applied for EU membership.

Radiocarbon from Pile Graphite; Chemical Methods for its Concentration
Abstract. Samples of pile graphite, irradiated in a test-hole at Hanford for 15 months, have been assayed for radioactive C14, yielding 0.38 ± 0.04 microcuries per gram. At this level of activity, the pile graphite contains very valuable amounts of C14. The relation between the above assay and the probable average assay of pile graphite is discussed, and it is concluded that the latter is almost certainly above 0.3 uc/ gram. Controlled oxidation of this graphite, either with oxygen at ~ 750°C, or with chromic acid "cleaning solution" at room temperature, yields early fractions which are highly enriched in C14. Concentrations of 5-fold with oxygen, and 50-fold with CRO{sub3}, have been observed. The relation between the observed enrichment and the Wigner effect is discussed, and a mechanism accounting for the observations put forward. According to this, about 25% of the stable carbon atoms in the lattice have been displaced by Wigner effect, a large fraction of which have healed the migrating to crystal edges. All the C14 atoms have been displaced, and the same fraction of these migrate to the edges. The enrichment then results from surface oxidation, in the oxygen case. Predictions are made on the basis of this …
