Dear Mr. Jones:
SUBJECT:
ORDER FOR MODIFICATION OF LICENSE CONCERNING PRIMARY COOLANT SYSTEM PRESSURE ISOLATION YALVES This letter transmits an Order for Modification of License which revises the Technical Specifications for Facility Operating License No. DPR-40 for the Fort Calhoun Station, Unit No.1 Nuclear Plant. The change is a result of the information you provided in response to our 10 CFR 50.54(f) letter of February 23, 1980, regarding primary coolant system pressure isolation valves. Based upon our review of your response, as well as other previously docketed infomation, we have concluded that a WASH-1400 Event Y valve configuration exists at your facility and that corrective action as defined in the attached Order is necessary.
Attached to the Order for Modification of License is the Technical Evaluation Report (TER) which supports the Order; and the plant Technical i
Specifications which will ensure public health and safety over the operating life of your facility. We are aware that there may be edi-torial corrections to the attached TER. Please note that the Technical Specifications correctly delineate the requirements for your facility.
In addition to Event V valve configurations, we are continuing our i
efforts to review other configurations located at high pressure / low pressure system boundaries for their potential risk contribution to an intersystem LOCA. Therefore, further activity regarding the broader topic of intersystem LOCA's may bc expected in the future.
