converters, wavelength calibration problems, etc.) relative to the capabilities of present day FTlR instrumentation. In addition,<br />
commercial infrared spectra compilations do not adequately address militarily significant, or directly related, compounds. The<br />
objective of this effort is to create, validate, <strong>and</strong> maintain a vapor phase FTIR database, with a focus on compounds of military<br />
significance or potential terrorist threat, using instrumentation that reflects current analytical capabilities.<br />

Officer Street-to-Fleet Database: Exp<strong>and</strong>ing Capabilities is a follow-on study sponsored by N81. In the earlier study, the<br />
sponsor asked us to develop a database for officers that merged training files with personnel files in order to calculate<br />
time-to-train to first assignment (TTT) metrics for officer communities. The result was the beginning of the Officer<br />
Street-to-Fleet (OSTF) database. In this study, we calculated TTT metrics for pilots <strong>and</strong> NFOs by specific training pipeline,<br />
identified some areas of concern for NFO attrition, extended our TTT calculations to the large restricted line (RL)<br />
communities, <strong>and</strong> exp<strong>and</strong>ed the database to include officer accessions from FY 1993 to FY 2002. (U) We found that average<br />
TTT fell for all aviation training pipelines since FY 1993 but that attrition rose slightly for most pipelines over the same period.<br />
In particular helicopter training attrition rose substantially for the FY 1996 <strong>and</strong> FY 1997 accession cohorts. We also found that<br />
the increase in NFO attrition is related to an increase in the number of OCS accessions, historically an accession source with<br />
high attrition rates. Finally, we found recent decreases in average TTT in RL communities.<br />

Brillouin scattering from biological materials is conducted using a t<strong>and</strong>em Fabry-Perot interferometer. The interferometer<br />
is uniquely designed to measure small frequency shifts that are characteristic of Brillouin scattering. Brillouin scattering from<br />
DNA, ovalbumen, the Bacillus spores globigii <strong>and</strong> thuringiensis were measured to determine the feasibility of biological<br />
material discrimination using Brillouin scattering. It was found that all biological materials exhibited unique Brillouin spectra<br />
<strong>and</strong> that it was possible to discern Bacillus spores at the species level. It is concluded that Brillouin spectroscopy has great<br />
potential as an optical tool for the detection <strong>and</strong> discrimination of threat biological materials. The only limitation in this<br />
approach is that the cross sections are small, <strong>and</strong> the tool is best suited for either point detection or short distance remote<br />
detection.<br />

On December 16, 1999, The USA Nuclear Regulatory Commission issued Design Certification of the AP600 st<strong>and</strong>ard<br />
nuclear reactor design. This culminated an 8-year review of the AP600 design, safety analysis <strong>and</strong> probabilistic risk<br />
assessment. The AP600 is a 600 MWe reactor that utilizes passive safety features that, once actuated, depend only on natural<br />
forces such as gravity <strong>and</strong> natural circulation to perform all required safety functions. These passive safety systems result in<br />
increased plant safety <strong>and</strong> have also significantly simplified plant systems <strong>and</strong> equipment, resulting in simplified plant<br />
