I feel we have dealt well with the difficulties imposed by an uncertain Laboratory budget and we have made notable progress in .some of the many research projects we pursue. This year marked a change of leadership in the Isotope and Structural Chemistry Group (INC-4) as well as in the Isotope Geochemistry Croup (lNC-7^. Basil Swanson and Ernie Bryant are returning to research activities after serving as Group Leaders for four and seven years, respectively. The two groups have grown and flourished under their leadership during some very challenging times. We applaud them and welcome Boh Ryan and Bruce Crowe as the new leadership in INC-4 and INC-7. We are extremely proud of Greg Kubas. who was named a Laboratory Fellow on the basis of his technical accomplishments during the fifteen years he has been in the Isotope and Structural Chemistry Group (INC-4). The contributions of Jeff Hay (T-12) and Judith Biustoek (X-U) during their Internal Professional and Renewal Leave with INC-4 and INC-11, respectively, were noteworthy and mutually beneficial. Carol Burns began her appointment as a J. Robert Oppeuheimer fellow in November 1987. We welcome her. This Annual Report lists many significant technical accomplish- ments within the Division, and I also wish to cite a special achieve- ment by the ICON section of Group INC-4. On schedule and within budget, they met a unique need through dedicated effoits. The project was a prime Donald W. Barr example of the synergism between ongoing research efforts and ultimate INC Division Leader program needs. After many years, our plans for badly needed space and updated facilities at Site TA-48 are finally coining to fruition. Construction of the Advanced Radioehemistrv Weapons Diagnostic Facility is nearing completion. This 15 000-ft- building will be occupied in December 1987. The new 4000-ft2 Weapons Diagnostic Instrument Development Building will also be ready to occupy in that month. We are now ready to concentrate our efforts on plans for a new research reactor to replace the aging Omega West reactor built 30 years ago. Like Omega West, the future research reactor will serve the Laboratory and institutions from both the US and abroad. Funding decreases in the Nevada testing program and the Nevada Nuclear Waste Storage Investigations necessitated a 4% cutback in our work force this yeir. We were able to keep this reduction to a minimum by implementing several cost-saving measures within the Division. On the positive side, we were able to assist in the placement of one-half of the affected employees.' I sincerely regret the necessity for this reduction-in-force. The FY 1987-88 planning- funding cycle has been an inconstant process throughout the Laboratory. Under the Director's guidance, the Laboratory has embarked on a comprehensive plan to ensure its pre-eminence for the next decade. Toward this end, the Laboratory's Senior Management has formulated a guideline for strategic planning titled LA-2000: many INC personnel will be contributing to this important plan in the coming year. To stress technical excellence and achievement as critical institutional values by more clearly defining the roles of the employees, the Senior Management made several decisions. A management title restructuring was implemented and a new job classification system for all structured series employees is progressing well. I view these initiatives optimistically as proactive moves to help ensure institutional stability during a time of rapid national change.
