_S,uhir e;t,: NEWS MHDIA INTEREST CONCERNING ALLEGATIONS OF OPERATTONS AT DRESDXN This is to provide notification of high press interes' in two apparent allegations concerning operations 4! the Dresden Nuclear Power Station. On September 4,1980, a reporter from the Chicago Sun Tim s ncuspaper contacted NRC re.sident inspectors at Dret Jen. Region III (Chicago) pornonnel, and GECo personnel el Drenden nnd the corporate offices lu regard to charges by an unidentified individuni that 300,000 to 400.000 gallons of radioactive water has been leaking Etem the Dresden Station cince July, 1980. In later conversationn reportern n11uded that their "soureee" claimed that varar had been disappearing for several years and that the proble.m had gotten no had that action had to be taken.
The Resident Tnapector was first notified of this matter by a H tnLinn operator ou Auguwt 28, 1980. The licensee informed the resident inspector Lhut he wnR intending to inferm the NRC once it was deternined whether or not a wa ter lors was ectually occurring. Subsequently, on September 4, 1980, i t was notArminad that one of the LPCI heat exchanger s was leaking, to the service water system, and eveutually to the environment, at approximately 2tpm. The leak. lug he.at exchanger wns immedia tely isolated, and the NRC was notified via the Rnd Phone at 9 :17 p.m.
nn September 4, 1980. The whing heat exchanger does not Appe.ar to acenunt f nr the total diaccepancy in wster f sventory. Investigations into cauwes of the discrep-ancy are continuing.
, N licensee reported prelimin.uy data to the resident inspe.ctor which estimates the actgvity of the supprennion pon1 water being released via the heat exchanger al 5x10 Pci/L. It is alco encimated that 76,000 gClons of water has baen releaved whleh would result in a total release of 0.14ci . A f ollmup notif f e.arion will be trade to supply aa analysts of antun1 or probable releases.
A second allegation to the press involvew the resident inspector discovering two control room operatora which appeared to be alceping. Thiu mutter bus been and will conLinue to be pursued with station and utility tnanagement.
The allegations and media followup appeared in the September 5,1980 mornlug edition of the Chicago Sun Times. It is not kn rdn at this time if the licensee plars to issue a press relcasc. Region 111 does not plan a prew r el e.a m e a t thi n time , har will continu( to respond to media questions.
