36 5.3.4 Control Rod Drive Mechanisms i
(1)
The shim / safety rod drives have a maximum vertical travel of 24 inches l
and a withdrawal rate of approximately 6-inches per minute. The shim / safety rods are magnetically coupled to the drive mechanisms and I
drop into the core, by gravity, upon a scram signal.
(2)
The regulating rod drive has a maximum venicaltravel of 24 inches and a withdrawal rate of approximately 24 inches per minute. The regulating rod is mechanically coupled to its rod drive and does not respond to a scram signal.
(3)
Lights are provided on the operator's console to indicate upper limit, lower limit, and shim range for each shim / safety rod.
1 5.3.5 Startup Source
}
A neutron source is available of such a strength as to satisfy the requirements l
that the count rate is greater than 2 counts per second during a cold reactor startup.
[
5.4 Fissionable Material Storage 5.4.1 The fuel storage pit, which is located below the floor of the reactor pool and at the end opposite from the core, will be capable of storing the complete fuel inventory of either highly-enriched uranium (HEU) fuel or oflow-enriched uranium, but not both. The neutron f
multiplication factor of the fully loaded storage pit shall not exceed 0.9 under any conditions.
