This report describes the preparation and application of molecularly imprinted polymers (MIPs) for the highly selective analysis of target signature compounds. The overall goal of this project task is to exploit the high selectivity of MIPs to generate a pure and enriched fraction of target analyte from environmental samples, either during the sampling stage or immediately thereafter. Due to the high purity of analyte fraction obtained, simplified field portable instrumentation that is capable of high performance trace analysis can be constructed. Major sections contained in this FY 2004 Final Report describe: (1) the synthesis and evaluation of MIPs specific toward explosives, (2) the design, construction, and performance of a novel instrument for the trace aqueous analysis of G-series nerve agent hydrolysis compounds, and (3) interfacing MIP separations with ion mobility spectrometric detection.

The 2004 visual inspection of four Uruguay nuclear fuel assemblies stored in L-Basin was completed. This was the third inspection of this wet stored fuel since its arrival in the summer of 1998. Visual inspection photographs of the fuel from the previous and the recent inspections were compared and no evidence of significant corrosion was found on the individual fuel plate photographs. Fuel plates that showed areas of pitting in the cladding during the original receipt inspection were also identified during the 2004 inspection. However, a few pits were found on the non-fuel aluminum clamping plates that were not visible during the original and 2001 inspections.
