Subject:

Proposed Change Number (PCN) 534, "Containment Penetrations"

Dear Sir or Madam:

Attached is a CD containing the meteorological data files for the ARCON96 calculations as requested by the NRC Staff reviewers on October 4, 2004. Also attached is a summary of the CD directory and file naming conventions.

If you have any questions or require additional information, please contact Mr. Jack Rainsberry at 949-368-7420.

Sincerely, Enclosures cc: B. S. Mallett, Regional Administrator, NRC Region IV (without enclosures)

B. M. Pham, NRC Project Manager, San Onofre Units 2 and 3 C. C. Osterholtz, NRC Senior Resident Inspector, San Onofre Units 2 and 3 (without enclosures)

S. Y. Hsu, Department of Health Services, Radiologic Health Branch (without enclosures)

Per your request, the attached CD contains an electronic copy of the meteorological data files used as input to the ARCON96 computer runs as well as copies of the resulting ARCON96 output files. Also included are the ARCON96 data input files.

The CD is organized with three directories. The first directory uMetDatau contains the meteorological data files for years 1993 through 2002. The second directory uEqHatch-through" contains the ARCON96 input and output files for the equipment hatch release path assuming that the release plume flows over (through) the containment building. The third directory "EqHatch-around" contains the ARCON96 input and output files for the equipment hatch release path assuming that the plume flows around the containment building.

The ARCON96 input and output files employ the following naming convention:

FILE RELEASE POINT RELEASE PATH RECEPTOR NAME eh-hv-u2 Unit 2 Eq. Hatch Over Containment normal control room (CR) air intake eh-hv-u3 Unit 3 Eq. Hatch Over Containment normal CR air intake eh-u2-u2 Unit 2 Eq. Hatch Over Containment Unit 2 CR emergency air intake A206 eh-u2-u3 Unit 3 Eq.
