About this file
This is a requirements document specifying technical specifications for a can cutter to be used inside a glovebox at the Savannah River Site. The can cutter must be designed to cut through three nested stainless steel canisters compliant with DOE standard 3013, with the outer can having maximum thickness of 0.150", inner can 0.08", and convenience can 0.05". The device must fit through a 12" bag-out port, be modularly assembled inside the glovebox, and not exceed 238 lbs.
Key technical requirements include: ability to cut canisters of varying diameters (4.921" to 3.937" OD) and lengths (up to 10.5"), burnishing capability to remove sharp edges, external electrical controls with diagnostic indicators, no wireless capabilities, and compliance with NFPA 70/NEMA standards. The unit must operate in 68-74°F and 30-60% humidity conditions within a potentially radioactive/dusty environment. Design considerations emphasize operator mobility, maintenance accessibility, ergonomics, and minimization of sharp edges. Suppliers must provide evidence of past performance, quality assurance manual, manufacturing specifications, and delivery timeframes, with responses due by March 17, 2025.

REQUIREMENTS-OPERATING CONDITIONS-CONSIDERATIONS
1 | P a g e
Requirements:
1) The can cutter must fit inside of a glovebox with a 12” bag-out port (Can be introduced modularly). The cutter shall be able to be assembled within the glovebox in interchangeable parts. The can cutter shall be easily assembled and disassembled within glovebox confinements. The can cutter shall be designed in a manner that allows operators to install and operate with limited mobility (multiple pairs of coveralls and gloves).
2) The can cutter shall cut around the cylindrical diameter of the cans. The method of cutting the 3013 canister assembly shall be cut in a manner that does not generate chips. Cutting methods such as water jets, lasers, etc. shall not be utilized for cutting operations.
3) The can cutter shall be capable of cutting through various thicknesses of stainless-steel containers that make up the 3013 assembly. The maximum expected thickness of the 3013 outer welded canister is approximately 0.150”. The maximum expected thickness of the inner welded canister is approximately 0.08”. The maximum expected thickness of the convenience can is approximately 0.05”.
a. The 3013 Outer Welded Can and 3013 Inner Welded Can may be cut horizontally or longitudinally.
b. The convenience can (inner most can) shall be cut vertically to prevent spillage of the contained powder.
4) The can cutter shall be designed to fit the lengths of the 3013 canister assemblies. The canister length varies by style of canister, but the maximum canister length of the 3013 outer welded can is approximately 10.5“. The inner 3013 welded can has a maximum length of approximately 9.5”. The innermost can is expected to be approximately 8” in length.
5) The can cutter shall be designed to process the following outer diameters of the welded stainless-steel canisters.
A. 4.921” OD (3013 outer welded can)
B. 4.580” OD (3013 inner welded can)
C. 4.409” OD (convenience can – option 1)
D. 4.395” OD (convenience can – option 2)
E. 4.270” OD (convenience can – option 3)
F. 3.937” OD (convenience can – option 4)
6) The can cutter shall be capable of burnishing the resulting cuts on all containers in the 3013 assembly. The cut can pieces have the potential to generate SHARPS, or metal strands, burrs, or shavings that can rip, puncture or tear gloves during handling. The burnishing tool
2 | P a g e shall be designed to remove potential sharp edges generated during cutting operations, to minimize the SHARP generation rate inside of the glovebox.
7) The can cutter shall allow for easy removal (i.e. not requiring the use of tools) of the next innermost can after the preceding outer can is cut and burnished.
a. Alternatively, cutting of the inner welded can without removal from the outer welded can may be considered.
b. The design shall facilitate the easy removal of a cut, vertical convenience can to prevent spillage of the contained powder
8) The can cutter will be installed inside the glovebox and the electrical controls will be mounted outside of the glovebox. The can cutter shall provide a method of obtaining visible diagnostic information displaying errors, faults, etc. (i.e. indicator lights). The method of energizing the can cutter will be provided by penetrations in the roof the glove box.
9) The can cutter controls shall provide an option to adjust the can cutters parameters such as cutting speed. The can cutter controls shall include an emergency stop button.
a. The provided equipment shall comply with NFPA 70, 2017
b. The electric motors shall comply with NEMA MG-1, 2016
c. Electrical enclosures shall be NEMA 12, 4 or 4X in accordance with NEMA 250, 2018
d. Conductors and cables shall comply with Insulated Cable Engineers Association and National Electrical Manufactures Association standards.
10) The can cutter components shall minimize the use of organic materials such as wood, and plastics.
11) The weight of the can cutter shall not exceed 238 lbs.
12) The design shall include machine guarding in accordance with 29 CFR Subpart O, 1910.212.
13) The can cutter shall not have Wi-Fi, Bluetooth, or imaging capabilities.
Operating Conditions:
The can cutter shall be installed and operated inside of the glovebox. The temperature and humidity are approximately 68-74 °F and 30-60%. The interior of the Glovebox is potentially dusty, the service environment will include radioactive contamination.
Considerations:
3 | P a g e
1) Supplier must consider operator mobility regarding the installation and operability of the final product.
2) Supplier must consider that the design of the can cutter is easily accessible for performing maintenance on all components of the can cutter in a glovebox with limited dexterity.
3) Supplier must consider the tools utilized for performing maintenance activities and avoid using pointed tools to mitigate potential puncture of glovebox gloves.
4) Supplier must consider and implement an ergonomic design into can cutter final product.
5) Supplier must consider SHARP generation and seek to minimize or eliminate.
6) Supplier must consider easy adjustment for varying can sizes.
7) Supplier must consider the design of the can cutter to successfully operate within the glovebox environment.
