[External_Sender] Proposed TS for targets Attachments: Proposed Target Power History TS.docx

Bill, Attached you will find a proposed technical specification for the Mo-99 demonstration targets. This is in support of the license amendment request submitted by a letter dated April 13, 2012.

If you have any questions, please dont hesitate to contact me.

Regards, Steve Steve Reese Director Radiation Center Oregon State University Corvallis, OR 97331 541-737-2341

Proposed Target Power History TS.docx>>

5.5 Mo-99 Target Irradiation Applicability. This specification applies to the irradiation of Mo-99 demonstration targets.

Objective. The objective is to assure that the time that the Mo-99 demonstration targets are irradiated is limited by reactor power history.

Specifications. The Mo-99 demonstration targets shall be irradiated in a core lattice position for no more than 7.15-MW days (MWD).

Basis. The predicted radionuclide inventory was based upon a 6.5-day irradiation while the reactor is at full power (i.e., 1.1-MW). The multiple of these two numbers represents the effective full power days for the core while the targets are in the core lattice positions analyzed. This power history creates the source term inventory that was predicted for the accident analysis that could potentially be released from the uranium bearing material within the targets. Limiting the irradiation time to 7.15-MWD will ensure that the potential accident consequences are less than the dose limit for individual members of the general public identified in 10 CFR 20.1301.
