17 element cladding and to reduce neutron activation of dissolved materials.
Sneefftention:
(1)
The reactor shall not be operated unless there is at least 16 feet (4.88 m) of water above the core.
(2)
The resistivity of the pool water shall be greater than 0.2 l
megachm-cm as long as there are fuel elements in the pool.
Bases:
(1)
Cooling of the reactor core is provided by the natural convection in the reactor pool.
In order to maintain the convection flow path Intact the reactor core must be fully submerged.
Radiation levels at licensed power require a
~
sufficient depth of water for shleiding.

\\
(2)
A small rate of corrosion continuously occurs in a water-mstal system.
To limit this rate, and thereby extend the longevity and Integrity of the fuel cladding, a water purification system Is required.
Experience with water quality control at this and many other reactor facilities has shown that maintenance within the specified limit provides acceptable control of the corrosion rate.
(See section 5.2 of the SAR f or f urther inf ormation.)
l 3.4 Confinement Anettenbilltv:
This specification applies to the capability,of Isolating the reactor f acility f rom the unrestricted en'vironment when necessary.
Obtective:
To prevent the exposure to the public resulfing from airborne activity released into the reactor facility from exceeding the limits of 10 CFR 20.105 for unrestricted areas, and to be consistent with the ALARA concept.

ADMINISTRATIVE CONTROLS 6.1 Orcentration 6.1.1 Structure
\\
The Nuclear Reactor Facility is a part of the School of Mines and Metallurgy of the Utilversity of Missouri-Rolla.
The organizational structure is shown in Figure 6.1.
6.1.2 Responsibility The Dean of' the School of Mines and Metallurgy is the Individual responsible f or the reactor f acility's lices;sas (Level 1).
The Director of the Nuclear Reactor Facility is the contact person for the NRC and will have overall responsibility for management of the facility (Level 2).
The Reactor Manager shall-be responsible for the day-to-day operation and for ensuring that all operations are conducted in a safe manner and wIthin the Iimits prescribed by the fac!IIty IIconse and the provisions of the Radiation Safety Committee (Level 3).
During periods when the Reactor Manager is absent, his responsibilities are delegated to a Senior Operator (Level 4).
The Reactor Manager shall have a Bachelor's degree in engineering or science or an equivalent combination of education and experience from which comparable knowledge and abilities can be acquired. As soon as reasonably possible after being assigned to the position, the Reactor Manager shall obtain and maintain a NRC Senior Operators license.
Amendment No. 11
39 A Health Physicist who Is organizationally Independent of the Reactor Facility operations group, as shown In Figure 6.1, shall be responsible for radiological safety at the f'cility.
a 6.1.3 Staffing When the reactor is operating the following staffing conditions shall be mets
~
(1 )
At least two persons (one of whom is a licensed Senior j
Operator) shall be present in the Reactor Building.
(2)
A licensed Reactor Operator or Senior Operator shall be 1
present in the control room.
All rearrangements of the core, fuel movement, and associated Health Physics monitoring, or other nonroutine actions shall be supervised by a licensed Senior Operator.
When the reactor is being used for training purposes the following conditions shall be met:
(1)
Students and Trainees may operate the reactor under the direct supervision of a licensed Reactor Operator provided the excess reactivity is less than 0.7% delta k/k.
