penetrations, the pool coolant system, the rod-drive mechanisms, or the reactor safety system shall be made and tested in accor-dance with the specifications to which the systems were originally designed and fabricated or to the specifications approved by the Cri icality Safeguards Committee.
A system shall not be considered t
operable until after if is successfully tested.
8.2.10 Explosive materials may be radiographed using neutron beams from the reactor subject to the following conditions:
a.
The radiography.of explosives present in the beam at any one time shall be limited to devices containing in aggregate no nore than 1 pound equivalent TNT with no individual device containing more than C.2 pound (91 gram) equivalent TNT en-cased in a metal case.
b.
Explosive-devices (such as cartridges or shaped charges) whose discharge could produce a thrust in a definite direction shall be positioned so as to be aimed away from the reactor and its components.
c.
At any one time there shall be no more than one pound equivalent TNT in the reactor room housing the reactor. This one pound shall be an, aggregate composed of items none of which shall exceed 91 grams.
In the event of temporary interruption of NR operation, the explosives shall not remain in the reactor room for more than 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
d.
The maximum quantity of explosive material that may be stored outside the reactor building in a storage magazine or magazines for radiography with the Mark I ' reactor is 100 pounds of propellent (low explosive). Type 2 magazine (s) shall be used for Class B and or Class C explosives. The new high energy propellants may be detonable and should be handled as high explosives.
e.
All vertical neutron radiography beam ports shall be sealed to prevent explosive devices from falling inside to the bottom of the port.
In addition, appropriate regions at the top of the reactor tank,shall be covered to prevent explosive devices from falling through the tank water to the reactor core region.
f.
Blast shields shall be mounted on the bridge or other support structure to protect the vital control rod components and reactor power monitor detector channels for the radiography of explosives in amounts greater than 10 g.
g.
The radiation Beam stop shall be positioned over the objects being radiographed.

h.
Controls ' governing the handling of explosi es shall be in accor-dance with the following general requirements:
1.
Explosive devices shall be handled in accordance with Chapter 2 of Ref.1.
2.
Since exposure to excessive heat or high energy radiation may increase the possibility of energy release from the devices, such exposure shall be minimized.
3.
Personnel handling explosive devices shall be provided with and shall use special equipment as required, such as nonsparking tools, conductive footwear, personnel protective equipment, and grounded workbenches. Explosive devices shall be mounted on a grounded tray during radiography.
4.
Unshielded, high-frequency generating apparatus shall not be operated within 50 feet of any type of ' detonators.
5.
Appropriate WARNING and CAUTION notes, which identify potential hazards to personnel, shall be incorporated into the work procedures and similar documents for the intended operation.
6.
During presence of explosives in the reactor room, no smoking or open flame shall be permitted within the room in which the radiography is being done.
7.
Personnel handling explosives shall be permitted to carry spark-p'roducing or flame-producing items in their pockets.
8.
No hazardous materials such as solvents, paints, gasoline,.
or other volatile substances shall be located in working
~
areas.
9.
Minimum personnel shall be present during radiography of 4
explosives.
- 10. Personnel who will perform the neutron radiography shall have training in the hazards of explosive handling and shall be approved by the Company Explosive Supervisor.
11.
The suitability of safety measures shall be as detennined by the Company Explosive Supervisor.
