Adensam, NRC, same subject, dated November 4,1983 Reference 1 indicated that by February 1,1985 the B&W plant owner's would provide amended replies to Generic Letter 81-21 on natural circulation cooldown.
Reference 1 mentioned two different approaches that were being taken by the plant owners.
The first approach involved reactor vessel head venting to cool the head during natural circulation cooldown and the second involved adoption of the GPU analytical approach.
As stated in our previous response to GL 81-21 (Reference 2), the current plan for WNP-1 is to use intermittent head venting by operator action as described in BAW-1742, Rev.1 (transmitted with Reference 2) but we are also following the progress of Toledo Edison in their plans to use continuous venting for Davis-Besse.
Upon construction restart we will begin the process of selecting between these two " venting" options. With our commitment to install a head vent of some type, we do not plan on adopting the analytical approach to this issue.
