SITE DESCRIPTION - NNSA FY2005 Congressional Budget Request (638-641)
The Y-12 current and future missions are consistent with the Records of
Decision for the Disposition of Surplus Highly Enriched Uranium Environmental
Impact Statement (EIS) of July 29, 1996, the Stockpile Stewardship and
Management Programmatic Environmental Impact Statement (PEIS) of December
19, 1996, and the Storage and Disposition of Surplus, Weapons Usable Fissile
Materials PEIS of January 14, 1997.
BWXT Y-12, L.L.C. was awarded the contract for management and operation
of the site November 1, 2000.
Directed Stockpile Work (DSW)
The Y-12 Complex maintains the only capability in the U.S. to fabricate
precision parts and components (from certain materials) for nuclear weapons.
Every nuclear weapon produced in the U.S. has components that were fabricated
at Y-12. Y-12 is also involved in the evaluation of components and subsystems
returned from the stockpile, the dismantlement of secondaries, and the
processing of recovered special nuclear materials. The Complex is currently
in the fourth year of a 4½-year effort, supporting the refurbishment of
the W87 Life Extension Program (LEP). Planning is also underway to support
future LEPs, such as the B61 First Production Unit (FPU) currently scheduled
for February 2006 (Y-12)/June 2006 (Complex) and the W76 currently scheduled
for March 2007 (Y-12)/September 2007 (Complex).
Significant FY 2005 activities include: process prove-in for the B61,
preparation for the W76 FPU, and continuation of evaluation and dismantlement
Planned FY 2005 projects include: evaluate material properties for ceramics,
evaluate historical information on U-6Nb and Enriched Uranium (EU) properties
and determine material properties, and evaluate effect of proposed process
changes on Fogbank material properties.
Planned FY 2005 projects include: developing weapon specific aging models,
evaluation and process development for non-destructive laser gas sampling
system and enhanced low-temperature thermal decomposition system, evaluate
corrosion mechanisms for metals of interest, and continue special material
Advanced Simulation and Computing (ASCI) Campaign
Planned FY 2005 projects include: integrated monitoring of Y-12 application
availability and network performance, and inter-network infrastructure
to support data accessibility.
Planned FY 2005 projects include: Zone Refining, Enclosed Hazardous Material
Processing, Chip and Coolant, Alternate Feed Study, Sensors for Holdup,
IR Heating of Uranium, Manufacturing Engineering Integrated Desktop, Agile
Machine Tool, Materials Knowledge Repository, Casting Process Science
Basis, and Advanced Metrology Platform.
Readiness in Technical Base and Facilities (RTBF)
Key activities in FY 2005 include the continued safe operation of the
major Y-12 production facilities and preparation for material transfer
to the Highly Enriched Uranium Materials Facility (HEUMF) when completed.
In addition, the Purification Facility Construction project is currently
underway at Y-12 and the Beryllium Capability project begins design in
FY 2004 and construction in FY 2006.
Facilities and Infrastructure Recapitalization Program (FIRP)
Through the FIRP activities, Y-12 has been able to establish a strong
deferred maintenance reduction program that is focused on supporting DSW
and three major campaign activities: Enhanced Surveillance, Stockpile
Readiness, and Advanced Design and Production Technologies (ADAPT). FIRP
projects include the purchase and installation of new building dehumidification
units that, in turn, support the disassembly and study of weapon components
(stockpile evaluation). In addition, FIRP is replacing deteriorated natural
gas lines supplying stockpile maintenance activities. Significant investments
have also been made in roof repairs that are tied to ongoing production
activities (joint test assemblies, component dismantling activities, and
refurbishments of nuclear weapon systems) and in replacing two 1940-vintage
transformers that were a weak link in the electrical distribution system
supporting these mission activities. The key for each of these projects
is their direct link to the NNSA Stockpile Stewardship Program.
Y-12 has made significant and impressive progress in the demolition of
excess facilities and has demolished over 400,000 gross square feet of
facilities no longer needed. Y-12 is also starting the planning and execution
of five Line Item projects that address the most demanding utility issues
at Y-12 [Compressed Air Upgrade (design start in FY 2004; construction
in FY 2005), Steam Plant Life Extension (design start in FY 2005), potable
water, electrical distribution, and utility distribution systems) and
represent an investment of about $150 m over the next 7 years. FIRP also
has initiated the complex-wide Roof Asset Management Program (RAMP) to
establish and implement a corporate approach for the management of NNSA’s
roofing assets, which is expected to result in improved cost efficiencies,
improved quality of life extension of NNSA’s roofing assets, consistent
approach and common standards for optimal roofing repairs and replacement,
and additional deferred maintenance reduction.
Safeguards and Security
The plant has developed a Design Basis Threat (DBT) Implementation Plan
to address new DBT protection requirements. In FY 2005-2009, Y-12 Plant
will hire additional Security Police Officers. In FY 2005, the plant will
begin a two-year effort that provides centralized computer management
to control the use and application of personnel computers through a master
network. As part of the National Threat Level Alert System, the plant
may occasionally have to implement additional compensatory security measures.
These periods of heightened security require an increased expenditure
of funds and use of resources.
DEFENSE NUCLEAR NONPROLIFERATION
Fissile Materials Disposition
Y-12 serves as the lead for all surplus highly enriched uranium (HEU) disposition activities through the
HEU Disposition Program Office. Y-12 is also providing storage for surplus HEU pending disposition
via shipment to the U.S. Enrichment Corporation/ Tennessee Valley Authority (USEC/TVA).
