Dear Mr. Hunger:

j

SUBJECT:

PECO FROSSTEY FUEL PERFORMANCE CODE (TAC NO. 65871)

RE:

PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 & 3 As a result of the staffs consultants continuing review of the PECo FROSSTEY fuel performance code' described in the PECo report PECo-FMS-003 we find that

~

additional information is needed. Specifically, it is understood that PEco wishes to use the FROSSTEY code for gadolinia rod analyses, as well as for U02 fuel rod analyses.

In order for this code to be used for gadolinia rod I

analyses, PECo must submit the following:

1) the gadolinia material properties used in the code, 2) how gadolinia rod powers are determined as a function of burnup (including the radial' power distribution in the gadolinia pellet) for the specific analyses to be performed, and 3) the upper level of gadolinia concentrations to be used by PECo. An example of the U0 -Gd 0 material 9

23 properties that need to be addressed are theoretical density, thermal expansion, thermal conductivity, specific heat, and melting temperature, etc.

Should you have questions, please feel free to contact us.

l Sincerely,

/s/
