Subject:

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

Report of Bulk Chlorine Rail Shipments for 2003 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), tile NRC granted approval and issued Amendment No. 132. 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 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 two railroads that operate along the tracks adjacent to the plant, Guilford Rail System and New England Central Railroad, both provided information on chlorine shipped during the three year period covering 2001, 2002 and 2003. It is concluded from this information that the total number of rail cars shipped by both companies was either zero or not greater than 20, as compared to a total of 60 rail cars assumed in the analysis supporting Reference (a).

t BVY 03-110/Page 2 of 2 Changes in Quantity of Chlorine Chlorine shipments, if any, were in individual tank cars carrying 180,000 pounds or less. This weight is equivalent to approximately 15,350 gallons. The analysis supporting Reference (a) used a tank car capacity of 20,000 gallons, or 234,560 pounds, which bounds current shipments.

In addition, each rail company stated that there are no industrial or economic changes anticipated in the near future that would lead to either an increase in the frequency of cars shipped or capacity of the cars.
