CCNFIRMATORY ORDER I.
Vermont Yankee Nuclear Power Corporation (the licensee) is the holder of Facility Operating License No. DPR-28 which authorizes the Licensee to operate Vermont Yankee Nuclear Poser Station at power levels not in excess of 1593 megawatts thermal (rated power).
The facility is a boiling water reactor located at the Licensee's site in Windham County, Vermont.
II.
Over the past eleven years the subject of anticipated transients without scrar (ATWS) events and the manner in w-ich they should be considered in the design of nuclear ocwer plants has been discussed extensively between the Nuclear Regulatory Comission (NRC) Sta#f and the nuclear industry.
In April 1972, the Staff published a report on, " Anticipated Transients Without Scram f or Light-Water Reactors", NUREG-0460, Volumes 1 and 2, which sumarized technical considerations related to ATWS and made recomendations.
8003120 7 f/
2-Following additional investigations by the Staff and by the ACRS, the Staff issued Volume 3 of NUREG-0460, in December 1978.
Although final determination of all the design changes to nuclear power plants which may be necessary to respond to ATWS events has not yet been reached, the Staff has concluded that the addition of a Recirculation Pump Trip (RPT) in boiling water reactors (BWRs) would significantly limit the immediate consequences of an ATWS event.
Therefore, letters dated January 9,1979 were sent to the BWR licensees who did not have installed RPTs.
These letters:
- described the reasons for requiring an RPT at this time,
- described two alternative ways to provide an acceptable RPT, and
- requested that licensees provide an RPT implementation schedule which would provide for installation within two years.
III.
Because an RPT provides considerable additional assurance that a BWR can safely respond to an ATWS event, I have determined that installation of an RPT by BWR licensees should be completed as soon as practicable and in no event later than December 31, 1980.
In response to the letter of January 9,1979, and additional discussions with the Staff, the licensee committed, by letter dated February 4,1980, to installation of an RPT before reactor operation during calendar year 1981.
I have determined that this comnitment should be formalized by Order requiring that RPT installation be completec no later than December 31, 1980.
. IV.
Accordingly, pursuant to the Atomic Energy Act of 1954, as amended, and the Commission's regulations in 10 CFR Parts 2 and 50, IT IS HEREBY ORDERED THAT:
The licensee shall, by December 31, 1980, install a recirculation pump trip, or in the alternat h e, place and maintain its facility in a cold shutdown or refueling mode of operation.
V.
Any person who has an interest affected by this Order may request a hearing within twenty (20) days of the date of the Order.
Any request for a hearing will not stay the effectiveness of this Order.
Any request for a hearing shall be addressed to the Director, Office of Nuclear Reactor Regulation, d. S. Nuclear Regulatory Conmission, Washington, D. C.
20555.
If a hearing is requested by a person whose interst may be affected by this Order, the Conmission will issue an Order designating the time and place of any such hearing.
In light of the Licensee's expressed willingness to install an RPT, if a hearing is held concerning this Order the issue to be considered at the hearing shall be:
whether RPT installation should be implemented as prescribed in this Order.
