Safety Parameter Display System-(SPOS) Radiout;vity StatusL j

.By letter dated June 26, 1990, Alabama Power Company committed to add'a -I

-radioactivity status bar to the~SPDS top level summary display:and a. list '

~

of radiation monitor readings as a second level display.,_ By letter _ dated Aucust 10, 1990, the NRC-requested specific ~information about the inputs to each of these displays. . Provided'as Attachment 1.ja a list of key-radiation monitors which will be,used as' inputs totthe top level radioactivity status bar. This list attempts.to._ identify _.those monitors -i which would-provide concisetand meaningful >information about radioactivity-L in areas of interest during an accident.- Provided as Attachment-2 is a complete list of radiation monitors which vill be~ inputs tosthe second level display. i As previously stated, Alabama Power. Company will implement'the changes to -

the.SPDS as_ described above by,the end of:the second refueling outage' i following receipt cf NRC approval _of the proposed resolution.

If there are any questions, please advise. l l\
