Radioactive Specimen Manufacture

  • Within the Walton House Active Laboratory, Wood has the capability to produce a variety of complex geometry test specimens from a range of materials.  The capabilities include:

  • Wire Electric Discharge Machining (WEDM)

  • Precision Knee-Mill, with digital readout

  • Diamond Wheel slit saw  and Lathe

  • Band saw for large sample sectioning

  • Lead-lined glove-box with machining capabilities for high activity materials, previously used for ex-service graphite and contaminated steel components.

Wood have a team of design engineers, who can produce specimen and extraction drawings to customer requirements.

Non-Active Sample Manufacture

The capabilities listed above can also be used for machining of non-active materials, but in addition, Wood has two non-active machining facilities with the following capabilities

  • 3 off knee-milling machines

  • 3 off precision lathes

  • A horizontal surface grinder, with precision feed and position controls for optimised surface finish

  • Welding capabilities

  • Large band saw, with support apparatus

 

A non- active metallographic preparation facility is available for mounting and preparing samples for metallographic analysis (e.g. SEM, XRD, Micro-hardness, fractography, etc.). 

Example Specimens Manufactured at Wood:

 

  • ‘Dog-bone’ tensile specimens extracted from contaminated plastic pipe

  • Charpy Impact samples from ex-service stainless steel

  • M6 round tensile test specimens from ex-service weldment

  • Curved ‘dog-bone’ creep specimen from contaminated ex-service stainless steel

  • Activated Magnox Graphite 4-point bend and tensile specimen

  • 316 Stainless steel 12mm and 25mm compact tension fatigue samples

  • Active graphite thermal diffusivity and CTE samples

  • Flat section cross-weld tensile samples extracted from curved sections of stainless steel pipe
