Subject:

Supplement to letter dated of January 24, 2019, License Amendment Request to Remove Requirement for Fuel Temperature Measuring and Safety Channels while Transient Operation Modes are Precluded Mr. Balazik:

This letter serves as a supplement to the license amendment request letter submitted on January 24; 2019. That letter requested a license amendment for the purpose of modifying the existing technical specifications (TS) to allow for operation without an instrumented fuel element (JFE) and thus operation without a fuel temperature measuring/safety channel. This supplement serves to modify section 4 of the TS to remove certain surveillance requirements

_______________ when the IFE is not being used. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - * - * - _ .. _______________ ...

The footnote proposed in the letter of January 24, 2019, says:

(1) Sections_4.2.e (specifically the Fuel Element Temperature Safety Channel) and 4.2.f may be deferred if transient operation modes (Square Wave and Pulse) are precluded.

They shall be completed prior to returning the Fuel Element Temperature Measuring

• Channel back to operations.

We suggest replacing this with:

(1) Requirements relating to the Fuel Element Temperature Channel (Section 4.2.e, Fuel Element Temperature SCRAM test, and Secti9n 4.2.f, Fuel Element Temperature Measuring Channel calibration) may be deferred if transient operation modes (Square Wave and Pulse) are precluded. They shall be completed prior to returning the Fuel Element Temperature Measuring Channel back to operations.

(2) For Section 4.2.e, the safety channels and interlocks from Table 2 and 3 that are only required for Square Wave and/or Pulse modes may be deferred if transient operation modes are precluded. These tests shall be completed as soon as practicable when transient operation modes are no longer precluded.

The issue at hand is that while the IFE is not being utilized, in addition to the JFE itself, the surveillances required for interlocks and safety channels associated with the JFE should also be d~ferred.  ;{-o z_o

I hereby affirm, state, and declare under penalty of perjury that the foregoing is true and correct.

Executed on: 2/28/19 If you have any questions, please do not hesitate to contact me.
