Subject:

Vermont Yankee Nuclear Power Station License No. DPR-28 (Docket No. 50-271)

Report of Bulk Chlorine Rail Shipments - 2006 In Reference (a), Vermont Yankee (VY) submitted a proposed change to the Technical Specifications requesting approval to remove the Toxic Gas Monitoring System. In Reference (b), the NRC granted approval and issued Amendment No. 132 to VY's Operating License. As a condition for granting the amendment, the NRC required that every three years, starting in 1994, VY submit a report providing the annual frequency of railroad shipments of bulk chlorine within five miles of the plant site. The NRC required the evaluation to verify that the probability of loss of Control Room habitability continues to meet the acceptance criteria of section 2.2.3 of the NRC Standard Review Plan (NUREG-0800, July 1981). The NRC also required that the report consider any changes in the quantity of chlorine in each shipment and that the report reference the number and date of the license amendment. This letter constitutes the required report and summarizes our evaluation.

VY conducted an evaluation of rail shipments of bulk chlorine. The evaluation included the following:

1. A determination of the annual frequency of rail shipments of bulk chlorine within five miles of the plant site, and

2. Consideration of any changes in the quantity of chlorine in each shipment.

Annual Frequency of Rail Shipments The railroads that operate along the tracks adjacent to the plant provided information on bulk chlorine shipped during the three year period covering 2004, 2005 and 2006. It is concluded from this information that the total number of rail cars shipped by the rail companies was less than the total of 60 rail cars per year assumed in the analysis supporting Reference (a).

BVY 07-021 Docket No. 50-271 Page 2 of 2 Changes in Quantity of Chlorine Chlorine shipments were in individual tank cars that were confirmed to be within the assumed tank car capacity used in our analysis.

There are no new regulatory commitments contained in this submittal.
