RE:
Dresden Nuclear Power Station, Unit Nos. 2 and 3 Quad Cities Nuclear Power Station, Unit Nos. 1 and 2 By letter dated December 29, 1983, Commonwealth Edison Company (CECo) provided a response to Gerieric Letter 82-33~ This response specifically furnished a Safety Analysis Report (SAR) on CECo's Safety Parameter Display System (SPDS)..
The staff reviewed the SAR and prepared a Safety Evaluation (SE) which.concluded that the SPDS was incomplete because it did not have adequate is.olation devices.
The staff's SE was transmitted to you in a letter dated June*22,~ 1984.and included a description of the information and. data the staff nee.de'Cf to complete a final confinnatory review.
You provided the required information in letters dated August 30,, 1984 and October 17, 1984 and, following telephone conferences with the staff, in letters dated August 2~, 1985, June 4 and ~5, 1986.
