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 />

Study of Cost Effective Large Advanced Pressurized Water Reactors that Employ Passive Safety Features<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 />
