INITIAL EXAMINATION REPORT NO. 50-059/OL-08-01, TEXAS A&M UNIVERSITY AGN-201M REACTOR

Dear Dr. Juzaitis:

During the weeks of June 30, 2008 and July 18, 2008, the NRC administered an operator licensing examination at your Texas A&M University AGN-201M Reactor. The examination was conducted according to NUREG-1478, "Operator Licensing Examiner Standards for Research and Test Reactors," Revision 2. Examination questions and preliminary findings were discussed with those members of your staff identified in the enclosed report at the conclusion of the examination.

In accordance with Title 10 of the Code of Federal Regulations Section 2.390, a copy of this letter and the enclosures will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html. The NRC is forwarding the individual grades to you in a separate letter which will not be released publicly. Should you have any questions concerning this examination, please contact Mr. Paul V. Doyle Jr. at (301)415-1058 or via internet e-mail pvd@nrc.gov.

Sincerely,

/RA/
