6 10.2.8 Forced water-flow experiments may be carried out in the reactor following a favorable evaluation which shall include, in addition to those items specified in section 10.1.1, the considera-tion of blocked water flow and approval in accordance with section 10.1.
10.2.9 Any additions, modifications, or maintenance to the ventilation system, the core and its associated support structure, the pool or its penetrations, the pool coolant system, the rod drive mechanisms or the reactor safety system shall be made and tested in accordance with the specifications to which the systems were originally designed and fabricated or to specifications approved by the Criticality Safe-guards Committee.
A system shall not be considered operable until af ter it 'is successfully tested.
10.2.10 Explosive materials may be radiographed using neutron beams from the reactor subject to the following conditions:
a.
For explosive devices containing only Class B and C explosives:
1.
The radiography of explosives present in the beam (s) at any one time shall be limited to a quantity of:
(a) five pounds of explosive (equivalent TNT) if the individual devices contain no more than 0.25 pounds (114 grams); or (b) up to two pounds of explosive (equivalent TNT) pro-vided that only a single device is radiographed at one time.
2.
Explosive devices may be poiitioned for NR at or near the end of the beam port.
3.
Samples whose discharge could produce a thrust in a definite direction shall be oriented so as to be aimed away from the reactor and its components.
4.
At any one time there shall be no more than 25 pounds of explosive in the reactor room in designated storage areas.
This 25 pounds shall be composed of lots none of which shall exceed 2.5 pounds of explosive.
During temporary interrup-tions of NR operation, the storage shall not exceed 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
5.
Up to 100 pounds of explosive may be stored up to eight hours outside the reactor building in a temporary holding area for the purpose of preparation for NR.
~

6 6.
Up to 2000 pounds of explosive may be stored outside the reactor building at a remote site at a distance and under such storage conditions as are applicable to the site.
7.
The new high energy propellents may be detonable and should be handled as high explosives.
b.
For devices containing high explosives, or a combination of high explosives and Class B and/or Class C explosive:
1.
The radiography of devices present in the beam at any one time shall be limited to a single device containing no more than 5 pounds (equivalent TNT).
2.
During radiography, the explosive device shall be placed no closer than 5 feet from the upper end of the vertical beam port.
3.
The aperture of the upper end of the beam port shall be reduced by shock and blast absorbing materials to 150%
of the cross sectional area of the high expolsive device (product of the effective length and diameter of the explosive device).
4.
At any one time the storage in the reactor room shall be limited to the quantity being radiographed.
5.
During temporary interruptions of NR operation, the explosives in 10.2.10(a) and (b) may remain in the reactor room for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
6.
Up to 10 pounds of high explosive (equivalent TNT) or combina-tion of high explosive and Class B and/or C explosives may be stored outside the reactor building in Type 1 magazines or in shipping containers suitable for highway transportation.
7.
Up to 50 pounds of high explosive (equivalent TNT) or a combi-nation of high explosive and Class B and/or Class C explosive may be stored at a remote site under such conditions as are applicable to the site and are approved.
8.
A shock and fragment absorbing shield shall be positioned so as to attenuate the shock wave, blast and fragments and to protect the bridge, other vital support structures, vital control rod components, reactor power monitor detector equipment, and personnel.
15a
9.
Devices whose discharge could result in highly directional energy releases shall be oriented so that high energy pro-jectiles or shock waves will not be directed towards the reactor core upon detonation.
- 10. The new high energy propellants may be detonable and should be handled as high explosives.
c.
All neutron radiography shall be conducted according to the following conditions:
1.
All vertical neutron radiography beam ports shall be sealed to prevent explosives 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 explosives from fa' ling through the tank water to the reactor core region.
2.
Blast or containment shields shall be installed to protect the vital control rod components and reactor power monitor detector channels for the radiography of explosives in amounts greater than 10 g.
3.
A radiation Beam Stop shall be positioned over the objects being radiographed.
4.
ControTs governing the handling of explosives shall be in accord:are with the following general requirements:
(a) Explosive devices shall be handled in accordance with Chapter 2 of Ref.1.
(b) Since exposure to exces'sive heat or high-energy radiation may increase the possibility of energy release from the devices, such exposure shall be minimized.
(c) Personnel handling explosive devices shall be pro-vided with and shall use special equipment as re-quired, such as nonspark.ing tools, conductive foot-i wear, personnel protective equipment, and grounded workbenches. Explosive devices shall be mounted on a grounded tray during radiography.
(d) Unshielded, high-frequency generating apparatus shall l
not be operated within 50 feet of any type of detonators.
i l
(e) 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.
15b
.During presence of explosives, no smoking or open (f) flame shall be permitted within the room in which the radiography is being done.
(g) Personnel handling explosives shall not be permitted to carry spark-producing or flame-producing items in their pockets.
(h) No hazardous materials such as solvents, paints, gasoline, or other volatile substances shall be located in the reactor room.
(i) Minimun personnel shall be present during the radio-graphy of explosives.
(j) Personnel who will perform the neutron radiography shall have training in the hazards of explosive handling and shall be approved by the Company Ex-plosive Supervisor.
(k) The suitability of safety measures shall be as determined by the Company Explosive Supervisor.
