TO ALL APPLICANTS FOR OPERATING LICENSES AND HOLDERS OF CONSTRUCTION PERMITS FOR POWER REACTORS

Gentlemen:

Subject: Clarification of Surveillance Requirements for Diesel Fuel Impurity Level Tests (Generic Letter No. 83-26)

It has come to our attention that the Surveillance Requirements for diesel fuel impurity level tests as stated in the Standard Technical Specifications (STS) in use by applicants for operating licenses require clarification. The current revision of the STS for each nuclear power reactor vendor does not clearly reflect the relationship between the STS testing requirements for diesel fuel impurity levels; guidance given in Regulatory Guide 1.137, Revision 1, and ANSI N195 (ASTM D270, ASTM D975 and ASTM D2274); and the NRC staff review performed in accordance with Standard Review Plans (SRP's 9.5.4 through 9.5.8). In order to clarify this relationship, the Surveillance Requirements for diesel fuel impurity level tests have been modified.

We have enclosed the revised Surveillance Requirements for diesel fuel impurity level tests that are to be used in your submittal of proposed Technical Specifications, or, if your proposed Technical Specifications have already been submitted, the staff will make the necessary revisions. These changes will also be incorporated in the next revision of the STS for all nuclear power reactor vendors. The generic changes are indicated by a line in the margin of the Surveillance Requirements.

This request has been approved by OMB Clearance Number 3150-0011, which expires April 30, 1985.

Sincerely,

Darrell G. Eisenhut, Director Division of Licensing

Enclosure: "Revised Surveillance Requirements for Diesel Fuel Impurity Level Tests"
