Dear Sir:
In accordance with Reference (c), Yankee Atomic Electric Company submits the subject report which is a revised version of the report submittad with I
Reference (b).
In Reference (c).we modified our request for review and approval of the Vermont Yankee One-Dimensional (1-D) kinetics topical reports f.YAEC-1693 and YAEC-1694) to incorporate a generic topical review and approval._:The enclosed. minor administrative changes to this report should K'
permit'your generic' review and approval of our 1-D kinetics methods to be
-finalized.
The report, " Application of One-Dimensional Kinetics to Boiling Water Reactor Transient Analysis Methods," YAEC-1693'(enclosed with Reference (b)),
presents the methodology, verification, and just ification for. application of RETRAN-02'l-D kinetics option to the prerently approved transient analysis methods.- - The report documents the method for analyzing boiling ws '.Ar reector transients with RETRAN-02 with the 1-D kinetics option using Vertrvat 'fenkee results to verify the methods.' The minor administrative' changes to the report
-which properly identify the generic applical. ion of-the methods occur in the

The report, " Method for Generation of One-Dimensional Kinetics Data for RETRAN-02 " YAEC-1694.(also enclosed with Reference (b)), does not require-Q reviolon for generic application because it is already presented in the-terminology of a generic topical report..
We trust that this information supports our request; however, should you have any questions on this matter, please contact us.
