' Mr. G. N. Ward, Manager Reload Licensing Exxon Nuclear Company, Inc.

2101 Horn Rapids Roads P; 0. Box 130 Richland, WA 99352

Dear Mr. Ward:

Subject:

Acceptance for Referencing of Licensing Topical Reports XN-NF-85-92(P), " Exxon Nuclear Uranium Dioxide /Gadolinia Irradiation Examination and Thermal Conductivity Results" and XN-75-27(P), Supplement 4, " Exxon Nuclear Neutronics Design Methods for Pressurized Water Reactors" We have completed our review of the subject topical reports. We find these reports are acceptable for referencing in license applications to the extent specified and under the limitations delineated in the reports and the associated NRC evaluation which is enclosed. The evaluation defines the basis for acceptance of the reports.

We do not intend to repeat our review of the matters described in the reports and found acceptable when the reports appear as references in license applications except to assure that the material presented is applicable to the specified plant involved. Our acceptance applies only to the matters described in the reports.

In accordance with procedures established in NUREG-0390, it is requested that Exxon publish accepted versions of these reports, proprietary and non-proprietary, within three months of receipt of this letter. The accepted versions should incorporate this letter and the enclosed evaluation between the title page and the abstract. The accepted versions shall include an -A (designating accepted) following the report identification symbol.

Should our criteria or regulations change such that our conclusions as to the acceptability of the reports are invalidated, Exxon and/or the licensees referencing the topical reports will be expected to revise and resubmit their respective documentation, or submit justification for the continued effective applicability of the topical reports without revisions of their respective documentation.

Sincerely, Crisinal algnoib(
