' JANUARY 1 0 1980 Docket Nos. 50-277 and 50-278 Mr. Edward G. Bauer, Jr., Esquire Vice President & General Counsel Philadelphia Electric Company 2301 Market Street Philadelphia, Pennsylvania 19101
Dear Mr. Bauer:
In response to our letter of Au,..st 29, 1978, you provided information on your 1977 experience of control rods failing to fully insert.
We evaluated your response along with those provided by other BWR owners.
We conclud1d that such events are general and that the frequencies of occurrence vary among the BWRs, apparently because of different maintenance programs.
Our August 29, 1978 letter recommended that you maintain an ongoing tabulation of any additional such events. To determine whether or not the frequency of these events has changed for a given plant, we now request that you report your more recent experience. This report should include the experience from the time of the last reported occurrence through 1979.
In addition please provide a summary of other control rod drive malfunctions, such as unlatchings, for the same time period.
The information should be provided within 90 days. For each event, identify the number of rods not fully inserted, the position of the rods, the cause for failure to fully insert, and any related maintenance activities.
This request for additional generic information is in accordance with the GAO blanket clearance number B-180225 (R0536) which expires June 30, 1981.
Sincerely,
/
- h Thomas ppolito, Chief Operating Reactors Branch #3 Division of Operating Reactors 000216g
