Dear Sir or Madam:
In Reference 1, Entergy Nuclear Operations, Inc. (Entergy) submitted a request, as supplemented by Reference 2, for an amendment to the renewed facility operating license Technical Specifications (TS) for Vermont Yankee requesting a change to the TS related to the drywell to suppression chamber vacuum breakers. This letter provides supplemental information to address a request for additional information (RAI) received on November 1, 2012 and discussed on a teleconference held November 1, 2012.
Attachment 1 to this submittal provides Entergy's response to the RAI and Attachment 2 provides revised TS and TS Bases pages reflecting the changes proposed to address NRC questions. The TS Bases page is provided for information only.
This supplement to the original license amendment request does not change the scope or conclusions in the original application, nor does it change Entergy's determination of no significant hazards consideration.
There are no new regulatory commitments being made in this letter.

.1 BVY 12-078 / Attachment 1 / page 1 of 1 Response to Request for Additional Information (RAI)
RAI The proposed Technical Specification (TS) change would allow the drywell-to-suppression chamber leak rate surveillance test to be performed any time during an operating cycle (OC) of 18 months as opposed to performing the test during every refueling outage (RFO). The proposed change would therefore allow the test frequency to be revised from a current frequency of 18 months to anywhere up to 36 months. In case the test is not performed during an RFO, and the plant is brought to power, it could allow entering a MODE where containment integrity is required without having met the surveillance requirement (SR). This would be in conflict with SR 4.0.1 which states:
SRs shall be met during the modes or other specified conditions in the Applicability for individual LCOs, unless otherwise stated in the SR. Failureto meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the LCO. Failureto perform a Surveillance within the specified frequency shall be failure to meet the LCO except as provided in SR 4.0.3. Surveillances do not have to be performed on inoperableequipment or variablesoutside specified limits.
Please explain how the proposed TS change ensures that the SR is met consistently every 18 months.
Note that in Standard Technical Specification (STS) (NUREG-1433, Volume 1, Revision 3),
the frequency for SR 3.6.1.1.2 is 18 months and has to be met in Modes 1, 2, and 3. The test frequency prevents from entering from MODE 5 to Mode 1, 2, or 3 without verifying containment integrity.
Response
Entergy agrees with this observation and proposes to revise the specified frequency of the drywell-to-suppression chamber leak rate test to once every 18 months, consistent with SR 3.6.1.1.2 in NUREG-1433 "Standard Technical Specifications General Electric Plants, BWR/4."
Attachment 2 provides revised TS and TS Bases pages reflecting this change.

VYNPS BASES: 4.7 (Cont'd)
Every 18 months, a leak rate test shall be performed to verify that significant leakage flow paths do not exist between the drywell and suppression chamber. The drywell pressure will be increased by at least 1 psi with respect to the suppression chamber pressure and held constant. The 2 psig set point will not be exceeded. The subsequent suppression chamber pressure transient (if any) will be monitored with a sensitive pressure gauge. If the drywell pressure cannot be increased by 1 psi over the suppression chamber pressure it would be because a significant leakage path exists; in this event the leakage source will be identified and eliminated before power operation is resumed. If the drywell pressure can be increased by 1 psi over the suppression chamber the rate of change of the suppression chamber pressure must not exceed a rate equivalent to the rate of leakage from the drywell through a 1-inch orifice. In the event the rate of change exceeds this value then the plant will be shut down, if operating, the source of leakage will be identified and addressed before power operation is resumed. Two consecutive test failures, however, would indicate unexpected primary containment degradation; in this event, increasing the frequency to once every 9 months is required until the situation is remedied as evidenced by passing two consecutive tests.
The drywell-suppression chamber vacuum breakers are exercised in accordance with Specification 4.6.E, following termination of discharge of steam into the suppression chamber from the safety/relief valves and following any operation that causes the vacuum breakers to open. This monitoring of valve operability is intended to assure that valve operability and position indication system performance does not degrade between refueling inspections.
When a vacuum breaker valve is exercised through an opening-closing cycle, the position indicating lights are designed to function as follows:
Full Closed 2 White - On (Closed to <0.050" open)
Open 2 White - Off
(>0.050" open to full open)
Experience has shown that a weekly measurement of the oxygen concentration in the primary containment assures adequate surveillance of the primary containment atmosphere.
B. and C. Standby Gas Treatment System and Secondary Containment System Initiating reactor building isolation and operation of the standby gas treatment system to maintain at least a 0.15 inch of water vacuum within the secondary containment provides an adequate test of the operation of the reactor building isolation valves, leakage tightness of the reactor building, and performance of the standby gas treatment system. The testing of reactor building automatic ventilation system isolation valves in accordance with Technical Specification 4.6.E demonstrates the operability of these valves. In addition, functional testing of initiating sensors and associated trip channels demonstrates the capability for automatic actuation. Periodic testing gives sufficient confidence of reactor building integrity and standby gas treatment system performance capability.
