Wilbur Nuclear Reactor Facility January 27, 2006 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Mail Stop 0-5 C12 Washington, DC 20555-0001 Re: Docket No. 50-134 License R-61 Annual Report for 2005 In accordance with the Technical Specifications for the WPI Leslie C. Wilbur Nuclear Reactor Facility (License R-61), I am submitting the Annual Operating Report for 2005.

The WPI reactor is a non-power, university-based, teaching reactor. It continues to be used primarily in the academic mission of Worcester Polytechnic Institute, for the instruction of students, and in occasional scholarly research.

Please contact me if further information is required.

Sincerely, Director, Nuclear Reactor Facility Cc: U.S. Nuclear Regulatory Commission ATTN: Mr. Thomas Dragoun 475 Allendale Road King of Prussia, PA 19406-1415 U.S. Nuclear Regulatory Commission ATTN: Mr. Patrick Isaac Mail Stop 01 2-G1 3 One White Flint North 11555 Rockville Pike Rockville, MD 20852-2738 American Nuclear Insurers 95 Glastonbury Boulevard Glastonbury, CT 06033

2005 Annual Operating Report Worcester Polytechnic Institute Leslie C. Wilbur Nuclear Reactor Facility License R-61 Docket No. 50-134 Operations Summary (a) changes in facility design There were no significant changes in facility design during 2005.

(b) performance characteristics The operation of all reactor safety system components was normal during 2005, except that in September, while performing a criticality check during the core reloading, one of the three trip actuator amplifiers failed causing one of the blades to drop into the core. The cause was determined to be an electronic failure.

Performance of the fuel was nornal.

(c) changes in operatingprocedures There were no changes made to operating procedures during 2005.

(d) abnormalresults of surveillance tests and inspections There were no unusual findings from the performance of surveillance tests and inspections.

(e) personnelchanges in reactorfacility director, health physicist, or radiation, health, and safety committee members There were no personnel changes in 2005.

IV. Maintenance In September 2005, while performing a criticality check during the core reloading, one of the three trip actuator amplifiers failed causing one of the blades to drop into the core.

The cause was determined to be an electronic failure, which was repaired by replacing two failed components.

V. Changes, Tests, and Experiments Pursuant to 10CFR 50.59 There have been no new tests or experiments requiring an evaluation pursuant to 10CFR50.59. An evaluation was performed for a minor equipment change when the four rod drive totalizers were replaced with a different model totalizer from a different manufacturer.

VI. Radioactive Effluents Release Liquid effluent releases have been near background and well within 10CFR20 release limits. Gaseous Ar-41 has been released in trace amounts that are conservatively calculated to be well within 10CFR20 release limits, and we have verified level 1 compliance using the EPA COMPLY Code.
