TEXAS ENGINEERING EXPERIMENT STATION TEXAS A&M UNIVERSITY cou.EGE STATION. TEXAS 77843-3575 [~ 'f ll W 1 L NUCLEAR SCIENCE CENTER 409/845-7551 96-0207 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555 SUBJEC'; Amendment of Facility Operating Licensu REF: Facility Operating License R-83, Docket No. 50-128

Dear Sir:

i

'It is requested that the Texas A&M University System Nuclear l

Science Center Reactor (NSCR) Facility License R-83 be amended to allow steady state operation up to 1500 kilowatts i.

(thermal). This power level increase will provide improved experimental conditions for the various reactor users.

TRIGA fuel is designed to operate at 2 MW without forced cooling and GenerallAtomics has operated the Mark III reactor at 1.5 MW for many years. A recent safety analysis of the NSCR found the maximum steady-state power density to be 26.82 kW/ element at 1.49 MW. This is below the 32 l kW/ element for the Torrey Pines Mark III and the 28 kW/ element analyzed in the NSCR's original SAR.

We hope to have the license amended by September 1, 1996.

This is near the annual maintenance period for the NSCR and would allow equipment and reactor calibrations at the new power level.

The suppbrting safety analysis and requested changes are i attached for your review.

Facility Licanos R-83

' Docket 50-128 Proposed Amendment to R-83 It is requested that section C.(1) of the licerme be amended to read as follows:

Maximum Power Level The Texas Engineering Experiment Station / Texas A&M University System is authorized to operate the reactor  ;

at a steady state power level up to a maximum of 1500 kilowatts (thermal) and to pulse the reactor in accordance with the limitations in the Technical Specifications. l t

Further, it is requested that Section 3.1.1, Steady State i l Operation, of the Technical Specifications be amended to  ;

read i

! i Specifications i The reactor power level shall not exceed 1.5 megawatts ,

under steady state conditions of operation. During l l periods of testing and instrument calibration, the ,

reactor may be operated up to a maximum of 1.75 '

megawatts.

Justification  ;

There has been an increase in the demand for the high neutron flux areas of the NSCR in the past few years. A .

reactor power level of 1.5 MW would improve the flux in all I l NSCR experiment locations. The majority of the research j performed at the facility uses neutron activation analysis  ;

which would benefit from the power increase. The General Atomic (GA) TRIGA fuel is designed to operate up to 2.0 MW with natural circulation cooling. GA Torrey Pines Mark III and Advanced TRIGA Prototype Reactors operated at 1.5 MW for  !

many years. An analysis of an upgrade of the NSCR to 1.49 l MW (1.49 was chosen for academic reasons) has been performed  !

and is attached as further support.

The decision to raise steady state reactor power to 1.5 vice 2.0 MW was based on the design capacity of the facility cooling system (2.0 MW cooling tower).

l Additional Safety Analysis l The recent safety analysis (August 1995) found that the

! maximum power density in the core would be 26.82 kW/ element.

j This is below the 28 kW/ element analyzed in the facility l Safety Analysis Report (SAR). Therefore, the SAR is more conservative for the limiting design basis accident and the loss of coolant accident.
