Subject:
Revision to Possession Only License for the University of Arizona Research Reactor, Facility License No. R-52, Docket No. 50-113 This letter revises the attachment to our 'possession only' request dated August 13, 2010.
Per today's conference call portions of our proposed Technical Specifications Amendment 19 which mention "a person with knowledge and experience equivalent to that of a licensed...operator" are not acceptable. Hence, attached are revised sections 4.4c, 6.1b, and 6.1d which return the wording back to our existing Technical Specifications Amendment 18.
Since May 21, 2010, we have:
- Ceased reactor operations,
" Partially unloaded fuel from Arizona Research Reactor so it contains insufficient fissile material present in the reactor core to attain criticality under optimum available conditions of moderation and reflection,
" Maintained the reactor in a "secured" condition,
" Continued our possession of the nuclear fuel,
" Maintained our surveillance activities, and
" Maintained the facility-including the storage, control, and maintenance of the spent fuel-in a safe condition until the defueling is completed.
By prior agreement, the DOE through its Reactor Fuel Assistance Program will assist in defueling our nuclear reactor following the end of operations.
I declare under penalty of perjury that the foregoing is true and correct. Executed on September 20, 2010.

Technical Specifications, Amendment No. 19 4.4 Maintenance Applicability-This specification applies to the surveillance requirements following maintenance of a control or safety system.
Objective The objective is to assure that a system is operable before being used after maintenance has been performed.
Specification
- a. Following maintenance or modification of a control or safety system or component, it shall be verified that the system is operable prior to its return to service. A system shall not be considered operable until after it is successfully tested.
- b. Any additions, modifications, or maintenance to the ventilation system, the core and its associated support structure, the pool or its penetrations, the pool coolint system, 1he rod drive mechanism, 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 Reactor Committee.
- c. A licensed reactor operator shall be present during maintenance of the reactor control and safety system.
Basis This specification relates to changes in reactor systems which could directly affect the safety of the reactor. Changes or replacements to these systems which meet the original design specifications are considered to meet the presently accepted operating criteria.
