Ginna Uprate Project S6 S Ginna is in a unique position for PWRs to safely accomplish an Extended Power Uprate of 17.2% thermal power.
The Westinghouse two-loop NSSS with 422V+ fuel has demonstrated the ability at Kewaunee to produce an equivalent thermal power.
Ginna replaced steam generators in 1996 with an oversized design that is fully capable of transferring the required heat.
Ginna replaced the reactor vessel head in 2003 to resolve the Alloy 600 PWSCC issue.

Ginna Uprate Project Constellation Energy is committed to investing what it takes to safely implement this power uprate while maintaining overall plant reliability for the extended license period.

The following schedule has been established for the Ginna power uprate:
o [Initiated Project in January 2004]
o Complete the engineering for spring 2005 refueling outage modifications in December 2004 o Implement the spring 2005 refueling outage modifications in April 2005 o Complete the RS-001 licensing report in May 2005 o Submit the License Amendment Request in June 2005 o Implement the fall 2006 refueling outage modifications in November 2006 o Startup and perform power escalation testing in November 2006 08/31/2004 5
Ginna Uprate Project S. 0 0 - -.
An integrated project team has been formed and is actively engaged.
Experienced vendors have been chosen to perform the engineering analyses (Westinghouse -NSSS/fuel, StoneEtWebster -
BOP/modifications, Siemens-Westinghouse - turbine/generator).
Independent industry experts have and will be chosen to supplement the engineering team in critical areas.
Lessons Learned are being incorporated from previous uprates.
An Executive Oversight Committee has been created to assure the right resources are applied to be successful.

Ginna Uprate Project A detailed feasibility study was completed in December 2003 including preliminary analysis of critical systems.
Based on the feasibility study and successful analyses for Kewaunee, the plant safety analysis will be successful with minimal modification of the NSSS and plant safety systems.
Only three safety related modifications are expected: upgrade to the standard 14 X 14 fuel assembly and modified fuel handling equipment, a fast-acting air actuator for the manual feed isolation valves, and a larger discharge MOV for the standby AFW pump.
All necessary modifications of the balance of plant will occur to retain overall plant reliability.

Operating License was issued in 1969.
Three potential types of responses to RS-001 Sections:
o Ginna Current Licensing Basis is consistent with SRP criteria and CLB/SRP criteria continue to be met.
o Ginna Current Licensing Basis is not consistent with SRP criteria and CLB continues to be met.
o Power uprate has no effect.

- 6 10CFR50.59 will be applied to determine when prior NRC review is required.
Preliminary evaluation indicates all plant modifications with the exception of the main feedwater isolation valves will not require prior NRC review.
The modification of the main feedwater isolation valves will require changes to the Technical Specifications in order to credit closure of the valves during MSLB.
Preliminary evaluation also indicates that the mechanical design of the uprate fuel assembly will not require prior NRC review.
