Dear Sir:
On October 16, 1978, Boston Edison Company submitted an application for an Amendment to Operating License No. DPR-35.
The amendments consisted of changes in those portions of the license pertaining to the receipt, possession, and use of byproduct source and special nuclear materials.
To further clarify the in-tent of that submittal, the following supplementary information is offered in accordance with Reference a.).
1 As indicated in Reference b.), Boston Edison Company's existing license specifies quantity limits in Sections 2.
(b), (c), (d), which authorize the receipt, posses-sion and use of byproduct source and special nuclear material.
Specifically, Section 2.
(b) limits station special nuclear material possession to 4100 kilograms of U-235, in connection with the operation of the facility.
This limitation will necessitate a number of licensing actions in the future as a result of fuel purchase j
for refueling, and subsequent spent fuel addition to the spent fuel storage pool, which now has a greater storage capacity per Reference c.).

Mr. Thomas A. Ippolito, Chief November 2, 1978 Page 2 In addition, Boston Edison Company's current license Section 2.
(c), which specifies quantity limits for possession of source materials, now prevents Pilgrim Station from purchasing an additional sealed source of Cs 137 in the amount of 170 C1, for instrument calibration purposes.
Therefore, the more generalized provisions as proposed in Reference b.) would reduce the number of required licensing actions as warranted by current posses-sion and use limits, and preclude the possibility of future delays.
Enclosed is a revision to our FSAR updating the source inventory in accordance with Regulatory Guide 1.70.3.
Should there be any further questions or concerns, please contact us.
Very truly yours, l
