Letter from Mr. G. Vanderheyden (CCNPP) to Document Control Desk (NRC), dated December 5, 2003, Response to Request for Additional Information Concerning the License Amendment Request: Extension of Diesel Generator Required Action Completion Time In our letter dated May 12, 2003 (Reference a), we requested a License Amendment that would extend several Required Action Completion Times for inoperable Diesel Generators (DGs). This letter provides the information requested in Reference (b). This information does not change the conclusions of the No Significant Hazards Consideration Determination or the Environmental Impact Review provided in Reference (a).

One of the proposed Technical Specification changes requested in Reference (a) involves Required Action Completion Time 3.8.1.E.5 for declaring the Control Room Emergency Ventilation System (CREVS), Control Room Emergency Temperature System (CRETS), and H2 Analyzer trains inoperable when the safety-related back-up power supply (DG) is inoperable. The original request was to extend the current 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months to 21 days when a single DG is inoperable (i.e., OC DG is available and three other safety-related DGs are operable) before the CREVS, CRETS, and H2 Analyzer trains are declared inoperable. We are revising the proposed Technical Specification change to extend the current 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months to 14 days when a single DG is inoperable before the CREVS, CRETS, and H2 Analyzer trains are declared inoperable.

Document Control Desk February 23, 2004 Page 2 An additional proposed Technical Specification change (Technical Specification 3.8.1 Condition 1) involves the condition when both DGs dedicated to redundant safety-related equipment are inoperable.

The original request was to extend the current Required Action Completion Time of 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months to 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

We are withdrawing this proposed change.

In our letter dated December 5, 2003 (Reference c), we provided a list of compensatory actions that will be taken when utilizing the 14-day DG Completion Time for Condition B. We are adding the following compensatory action:

The condition of the grid will be evaluated prior to entering the extended DG 3.8.1 Condition B Completion Time for elective maintenance. An extended DG Completion Time will not be entered to perform elective maintenance when grid stress conditions are considered "High" per our procedures.

This will include conditions such as extreme summer temperatures and/or high demand.

The information provided in this letter results in changes to the original marked-up Technical Specification pages. Therefore, this letter also provides a complete set of revised marked-up Technical Specification pages (see Attachment 1) and new final pages (see Attachment 2).

Please replace Reference (a) Attachments (3) and (4) with the Attachments to this letter.

SURVEILLANCE FREQUENCY 1-SR 3.8.1.3

NOTES ------------------

1. Performance of SR 3.8.1.9 satisfies this Surveillance Requirement.

2. All DG starts may be preceded by an engine prelube period and followed by a warmup period prior to loading.

3. A modified DG start involving idling and gradual acceleration to synchronous speed may be used for this Surveillance Requirement as recommended by the manufacturer. When modified start procedures are not used, the voltage and frequency tolerances of SR 3.8.1.9 must be met.

Verify each DG starts and achieves steady state voltage 2 4060 V and < 4400 V, and frequency 2 58.8 Hz and < 61.2 Hz.

NOTES ------------------

1. DG loadings may include gradual loading as recommended by the manufacturer.

2. Momentary transients below the load limit do not invalidate this test.

3. This Surveillance shall be conducted on only one DG at a time.

4. This Surveillance Requirement shall be preceded by and immediately follow without shutdown a successful performance of SR 3.8.1.3 or SR 3.8.1.9.

Verify each DG is synchronized and loaded, and operates for 2 60 minutes at a load 2 4000 kW for DG 1A and 2 2700 kW for DGs 1B, 2A, and 2B.

31 days SR 3.8.1.5 Verify each day tank contains 2 325 gallons 31 days of fuel oil for DG 1A and 2 275 gallons of fuel oil for DGs 1B, 2A, and 2B.

SR 3.8.1.6 Check for and remove accumulated water from 31 days each day tank.
