Dear Mr. Paperiello:

Reference (a) cited above lists two Open Items "...to incorpor-ate multiplet analysis into AAIS...".

(0 pen Items 50-254/82-13-03 and 50-265/82-15-03.)

These Open Items are part of a multitask project developed by Commonwealth Edison to enhance the performance of AAIS.

As outlined in the Reference (b), Task 1 " Multiplet Resolution and Peak Classification" addresses these Open Items.

Work on this task is in progress and on schedule.

Task 1 will be completed by July 2, 1984 in accordance with the schedule presented in Reference (d).

Completion of Task 1 will close out the Open Items.

Recognizing the need to improve the analytical sof tware of AAIS, three additional tasks were developed by Commonwealth Edslon to enhance spectral analysis.

Again, these tasks are further improvements which go beyond the concerns raised by the NRC and are presented here only for your information.

As outlined in Reference (c), they are:

Task 2:

Ef ficiency Calibration with Associated Uncertainties.

Completion and Implement by:

July 1, 1985.

Task 3:

Lower Limit of Detectability and Uncertainties Related to Activity Determination.

Implementation timetable by:

December 31, 1984 Task 4:

Background Compensation.

Implementation timetable by:

July 1, 1985 The dates presented above define a long term project designed to continually improve the performance of AAIS.

The completion of Task 1 xill close out the Open Items 50-254/82-13-03 and 50-265/82-15-03.

The other tasks will proceed as enhancements as they are identified, evaluated, and incorporated into the analytical software and procedures of AAIS.

Very truly yours, kt i
