SUBJECT:
RANCHO SECO RESPONSE TO IE BULLETIN 79-05A In response to a telephone request from Phil McKee on 4/12/79, Region V has reviewed Rancho Seco's response to IE Bulletin (IEB)79-05A.
The results of this review are as follows:
1.
The Licensee did not respond to the last sentence in action item 5 of IEB 79-05A.
Site inspectors have so informed the 8.icensee and they will include this item in their April 16th response.
2.
It should be noted that the Licensee response to item 5 of IEB 79-05A states that actual valve positions have been verified against pro-cedures for all valves except those located within containment.
3.
On page 2, third paragraph, of the Licensee response, the following statement is made:
"A temperature monitor downstream of this valve is alarmed to provide indication that the valve is open".
This monitor alarms at 200*F.
Once the valve opens and the alarm actuates, even if the valve subsequently shuts, it may be up to one hour or more before the temperature decreases sufficiently to clear the alarm.
Therefore, the alarm itself is not a good indicator of valve closure.
4.
Region V site inspectors have verified that the actions taken by h
the Licensee, as specified in their response to IEB 79-05A dated April 11, 1979, have been completed.
5 5.
With the exception of the above listed items, I feel that the h
Licensee has fully responded to Items 1,2,3,4.a and 5 of IEB 79-05A 6
and their stated actions are reasonable and correct.
