Program Objective: Assure the sufficient capacity is available in the production complex to meet production requirements for refurbishment efforts and limited life components needed to maintain the stockpile.
Subprogram Goal: Extend the service lifetimes and reliability of the nuclear weapons in the stockpile.
-Production of new neutron generators is necessary to expand the production for new gas transfer systems (both of high significance) -providing for the day-to-day maintenance activities of limited life components
-production and delivery of components—limited life components and others
-delivery of kits to military

http://www.acq.osd.mil/ncbdp/nm/nmbook/chapters/ch4.htm DSW Non-nuclear testing being conducted on a warhead. -Began in the mid-1960s, when weapons testing was done through
underground explosions of nuclear devices.
(Underground testing ended in the early 1990s.
-DOE’s program began in 1995. U.S. Ensure, through various tests, that the
reliability of nuclear weapons is maintained.
*Understand the effects of aging to reveal design and manufacturing defects.
(Alteration of the physical characteristics of the materials.)
*Develop diagnostic tools and predictive models that
will make it possible to analyze and predict the effects of
time on weapon materials, components and systems.

2.Evaluates the conditions of…
3.Tests: Non-nuclear flight tests, non-nuclear systems laboratory tests, and laboratory tests of the nuclear
4.Determine if there are any issues with weapons safety and performance. With special diagnostic
tools, the effects that impact weapon reliability, safety, and performance, will be able to be determined
5.(Refurbishment if necessary.)
6.Compatibility of DOD & DOE interfaces.
7.Activities (in surveillance/evaluation): Purpose: Nuclear weapon testing: Encompasses all experiments in which special nuclear material is placed in contact with high explosives, which are then detonated.
- > 6,000 parts (single weapon)
*Nuclear package=about 300 parts (primary & secondary assemblies)
-Firing set, detonators, neutron generators, etc. are tested to demonstrate their behavior as non-nuclear components
A.Full-yield nuclear test is unnecessary if…
6 states testing the nuclear devices achieve a nuclear detonation on the first try.
B.Full-yield nuclear test is necessary if…
Nuclear devices fail to detonate.
*First nuclear weapon used in combat incorporated an untested gun-assembled design
*First implosion device tested on July 16, 1945, near Alamogordo, NM (w/ an identical “physics package” [fissile and fusion fuels plus high explosives] incorporated into the bomb dropped on Nagasaki 1st Test: Full-yield nuclear test? Nuclear Weapon Testing http://ndep.nv.gov/boff/photo01.htm Hydrodynamics: Branch of science concerned with how fluids move and how they interact with boundaries.
-Inside a nuclear weapon: metals like plutonium are pressurized, shocked, and heated to an extensive amount
making them convert into fluids and mix with each other
1.High explosives, and other materials, emit powerful electric currents
2.Electrical currents create a full-scale nuclear weapon primary containing HE that is surrounds a metal pit
3.²³⁹Pu is replaced with a stunt double, or a mockup
a.Stunt double- similar behavior, same weight, density, and other metallurgic properties as ²³⁹Pu
i.Cannot undergo fission
5.Wave of detonation passes through the main HE charge
6.HE burn [or don’t detonate as designed ]
7.Pressure of detonation causes a shockwave to travel through the pit material, which responds by imploding
radially to a compact shape
8.Pit response: may eject material, and displays how the metal moves, flows, or melts
9.Tritium-deuterium boost gas is heated by pit implosion and the onset of the fissioning process
10.Gas undergoes nuclear fission, generating numerous high-energy neutrons
11.Neutrons enter the fissile pit material causing subsequent fissioning and boost-induced nuclear interactions
*Improper boosting may decrease weapon performance.
-X-ray radiographs are taken to capture the stages of the materials’ reactions [interaction and change]
-X-rays allow for the study of shapes, pressures, densities, surface tensions, and material distribution
[during a weapon’s explosion]
Computer calculations based on these test results are used to determine how a nuclear weapon may perform. Process Results Hydrodynamic Testing A room underneath the firing chamber houses high-speed optical cameras. Images from the hydrodynamic test are directed with mirrors in the firing chamber to ports at the tops of the black shrouds. https://www.llnl.gov/str/Sep07/Bosson.html 1.Fissile material is assembled to form a supercritical mass in which a chain
reaction begins and implodes.
2.A “full” nuclear yield is not delivered due to the supercritical mass not
being maintained for a long enough time.
3.Nuclear energy releases range from values less than milligrams to
kilograms to metric tons of TNT equivalent yield
Experiments are designed to…
Use nuclear devices modified in one of several ways, so that very little
nuclear energy release occurs.
Subcritical Experiments: scientific experiments that obtain technical information in support of DOE and NNSA Stockpile Stewardship and Management Programs.
a.No self-sustaining nuclear fission chain reaction occurs.
b.Involve chemical high explosives to generate high pressures that are
applied to nuclear weapon materials.
c.Configuration and quantities [of explosives and nuclear materials]: enough
so that no nuclear explosion may occur
d.Consistent with the Comprehensive Test Ban Treaty
e.1st experiment conduced at LANL: Rebound on July 2, 1997; 2nd
experiment conducted at LLNL: Holog on September 18, 1997

Y-12 Nuclear Material Storage http://www.oakridge.doe.gov/em/ssab/Stewardship-Kit/Files/HistoricalPhotos/Photos.htm - Becomes feedstock for new material,
- HEU in excess of national defense needs is down blended to provide fuel for nuclear reactors.
-Vendors: dispose of components and handle gear that are contaminated
- Components retained for reuse: placed in secure storage after cleaning and inspection
-Legacy components—parts produced for weapons that have been retired or are of
surplus—recycled or packaged for burial in secure licensed landfills at Y-12 or the Nevada Test Site
- Materials shipped in special containers
1st quarter of Fiscal Year 2006:
DSW’s Dismantlement and Disposition Program
shipped 3,100 cubic feet of classified,
contaminated, non-RCRA (Resource Conservation
and Recovery Act) components and materials
to the Nevada Test Site.
24% > amount planned Recycling of Nuclear Material Mixed-oxide fuel pellets consist of recycled plutonium in combination with other radioactive substances.
http://www.ornl.gov/info/ornlreview/v41_3_08/article11.shtml The purpose of nuclear weapon refurbishment is to provide corrective maintenance and weapon component replacement—to extend the viability of warheads beyond their designed end-of-life date. It is the national laboratories that start developing and certifying an engineering design for warhead modification through a combination of non-nuclear experiments, flight tests, physics and engineering analyses, and computer simulations. This design must address the requirements needed to extend the life of a system, meet all qualifications, certifications and requirements of the military, and support the directive schedule, including modifications and alterations. Once this design is complete, the weapons are returned from the field, and the degrading components are refurbished by means of Life Extension Programs. For assurance, the refurbished designs are created as closely as possible to the nuclear-tested designs.
The United States nuclear weapons stockpile was produced over thirty years ago. This lengthy amount of time has caused many of the warheads to begin to deteriorate. As a result, Life Extension Programs were created in hopes of refurbishing the weapons, and maintaining an active stockpile.
Life Extension Programs are designed for each weapon type and consist of specific solutions to extend the lifetime of each particular warhead. These programs include the identification and correction of potential technical issues with each weapon, and the refurbishment or replacement of components. Theses extension efforts are intended to extend the lifetime of a warhead or a component for an additional twenty to thirty years.
Refurbishment http://www.whitehouse.gov/omb/rewrite/budget/fy2003/bud14.html B-61 bomb undergoing refurbishment.
Contains approximately 6,000 component parts. The purpose of the dismantlement and disposition, or disposal, of nuclear weapons is to assist in the effort to transform the nuclear weapons complex and stockpile. The weapons are taken apart to ensure that they are of no further use, to reduce the overall size of the nuclear weapons stockpile, and to ensure that a country is meeting its international nonproliferation commitments. The process of warhead dismantlement and disposition includes all activities needed to reduce the surplus quantity of retired weapons or weapon components—interim storage, surveillance (or weapon analysis), and complete disposition of the retired weapons and components.
The dismantlement of a warhead is an extensive process…
1.Design laboratories work with the production faciities to identify and mitigate any hazards that may arise before a particular weapon type is dismantled.
2.The knowledge attained in developing the warhead is also used in the dismantling of the warhead.
3.The warhead is then retired and designated for dismantlement.
4.The weapon is brought to the Pantex Plant where all of its high explosives are removed from the nuclear material. The non-nuclear components are either
processed on site or sent to other facilities within the complex.
5.Y-12 National Security Complex dismantles the uranium components, while the Savannah River Site and Kansas City Plant complete the final processing of
the non-nuclear components.
*The Office of Secure Transportation moves the nuclear material and parts between sites ensuring that the work is completed securely and on-schedule.*
Today, there are several thousand retired nuclear weapons awaiting dismantlement.
