SUBJECT:

VERMONT YANKEE - REQUEST FOR ADDITIONAL INFORMATION REGARDING TECHNICAL SPECIFICATION CHANGE RELATING TO DEGRADED GRID PROTECTION SYSTEM INSTRUMENTATION (TAC NO. MD8011)

Dear Sir or Madam:

By letter dated February 12, 2008 (Agencywide Documents and Management System (ADAMS)

Accession No. ML080660458), Entergy Nuclear Operations, Inc. (the licensee) requested changes to Vermont Yankee Nuclear Power Station (VY) Technical Specification (TS).

The Nuclear Regulatory Commission staff has been reviewing TS Sections 2.1, 3.1, and 3.2 relating to degraded grid protection system instrumentation and has determined that additional information is needed to complete its review. The specific questions are found in the enclosed request for additional information (RAI). A response to this RAI is requested to be provided within 30 days.

Sincerely,

/RA/

ML081780213 OFFICE LPLI-1/PM LPLI-1/LA LPLI-1/BC NAME JKim SLittle MKowal DATE 6/27/08 7/02/08 7/02/08 VERMONT YANKEE - REQUEST FOR ADDITIONAL INFORMATION REGARDING TECHNICAL SPECIFICATION CHANGE RELATING TO DEGRADED GRID PROTECTION SYSTEM INSTRUMENTATION

1. Confirm whether the Emergency Core Cooling Systems (ECCS) loads are started simultaneously or through a load sequencer on receiving a safety injection (SI) signal when there is no loss of offsite power. Provide a logic diagram or explain how the degraded voltage protection system interfaces with the starting of various ECCS loads on receipt of SI signal when the ECCS loads are fed from (a) offsite power, (b) emergency diesel generator (EDG).
2. When the 4160 V safety-related buses are powered from the offsite power source at the minimum grid voltage, confirm the following during the sequencing of ECCS loads (or block load if applicable):

(1) Minimum steady state voltage assumed at the switchyard (offsite source), and the basis for this minimum switchyard voltage; (2) Minimum steady state voltage at the 4160 V safety-related buses; (3) Minimum (worst case) transient voltage at the motor control center starter for the farthest load - whether adequate to pickup the starter/contactor; (4) Minimum (worst case) transient voltage at the starting motor (farthest load) -

whether adequate to provide requisite torque to start the load; and (5) Minimum (worst case) transient voltage at the already running downstream Class 1E load terminals - whether adequate so that the load will not drop due to undervoltage at the downstream load.

3. In Section 8.5 of Final Safety Analysis Report (FSAR) of Vermont Yankee Nuclear Power Station (VYNPS), when the safety-loads are fed from the EDG, the licensee states that a voltage drop limit of 40% is established as a maximum voltage variation to occur during the starting of any load group shown in the starting sequence of Tables 8.5-1A and 1B, 8.5.2A and 2B, and 8.5.3A and 3B.

NRC Safety Guide 9 and Regulatory Guide 1.9 recommend that: At no time during the loading sequence should the frequency and voltage decrease to less than 95 percent of nominal and 75 percent of nominal, respectively. During sequencing of the ECCS loads from the EDG at Vermont Yankee, confirm the following:

(1) Minimum (worst case) transient voltage profile at the 4160 V safety-related buses; (2) Minimum (worst case) transient voltage at the motor control center starter for the farthest load - whether adequate to pickup the starter/contactor; Enclosure

(3) Minimum (worst case) transient voltage at the starting motor (farthest load) - whether adequate to start the load; and (4) Minimum (worst case) transient voltage at the already running downstream Class 1E load terminal - whether adequate so that the load will not drop due to undervoltage at the downstream load.

4. The proposed TS Table 3.2.8 ACTION Note 3 states in the end: If the action and associated completion time of Note 3.a or 3.b are not met, initiate increased voltage monitoring of the associated 4.16 kV emergency bus(es).

Describe in detail what is meant by increased voltage monitoring (i.e., logging requirements and time intervals).
