l Section I - Description of Modification The modification corrects a simple typographical error in Item 1.6 of Table 4.6-1, " Comparison of the James A. FitzPatrick Nuclear Power Plant Inservice Inspection Program to ASME Inservice In-spection Code Requirements". The subsolumn "5 years" under the column" Extent of Examination, % Intervals" has the value 8, which is incorrect. The correct entry is zero, as specified by Section XI of this 1970 ASME Code.

Section II - Purpose of the Modification In accordance with Section XI of the 197 0 edition of the ASME code, the visual exam required by Category E-2 shall be done at the time of the system hydrostatic test required by Section IS-  ;

520. Section IS-520 requires the hydrostatic test to be per-formed'at or near the end of the inspection interval, which is 10 years. The typographical error in the present Technical Specifi-cations would require a major hydrostatic test every 5 years which would subject the plant to needlessly high pressure. The purpose of the modification is to obviate some needless hydrostatic tests.  !

Section III - Impact of the Change These modifications will not alter the conclusions reached in the FSAR and SER accident analysit Section IV - Implementation of the -Modification The modification as proposed will not impact the ALARA or Fire Protection Program at JAF.

Section V - Conclusion The incorporation of these modifications: a) will not increase the probability nor the consequences of an accident or malfunction of

-equipment important to safety as previously evaluated in the Safety ~ ~

Analysis Report; b)' will not increase the possibility for an accident or malfunction of a different type than any evaluated previously in the Safety Analysis Report; and c) will not reduce the margin of safety.as defined in the basis for any Technical Specification, and d) .does not constitute an unreviewed safety question.
