Gentlemen:

On May 3, 1989, the NRC Project Manager for the Brunswick Steam Electric Plant (BSEP), Units 1 and 2, requested information concerning the current configurations of the spent fuel pools at BSEP and Carolina Power & Light Company's future plans for spent fuel storage. This ,

information is provided below. I Unit 1 Spent Fuel Pool Unit 1 is currently licensed to allow storage of 1803 BWR and 160 PWR spent fuel assemblies. Prior to Amendment 61 to the BSEP-1 Technical Specifications, dated December 15, 1983, the license allowed storage of 1386 BWR assemblies and 616 PWR assemblies. Amendment 61 was pursued for two reasons; (1) some of the existing BWR racks were to be replaced I with high-density BWR racks which contained absorber material in the walls so spacing between stored assemblies could be reduced while maintaining adequate criticality margin, and (2) the Company intended to only store 160 PWR fuel assemblies in the Unit 1 spent fuel pool. 1173 LJR spaces (one 13X15, one 13X17, one 13X19, and two 15X17 racks) are now high density cells. The remaining 630 BWR spaces are in fifteen 6X6 and five 3X6 low density racks. The 160 PWR fuel assemblies are stored in ten 4X4 PWR racks. Currently, one of the 6X6 BWR racks is not installed; however, should the need arise, the rack can bo installed.

6 Therefore, the current installed capacity is less than that allowed by the Technical Specifications by one less 6X6 BWR rack.

er Unit 2 Spent Fuel Pool eb ggo. Unit 2 is currently licensed to allow storage of 1839 BWR and 144 PWR oo spent fuel assemblies. Prior to Amendment 87 to the BSEP-2 Technical (o Specifications, dated December 15, 1983, the license allowed storage of 1386 BWR assemblies and 616 PWR assemblies. As in Unit 1, 1173 BWR g

-u spaces are high density cells, and the remaining 666 BWR spaces are in

$8 sixteen 6X6 and five 3X6 low density racks. Currently, there are ten y< 4X4 PWR racks; one more than necessary for storage of 144 PWR assemblics in E .

, NLS-89-130 / Page 2 to allow storage configuration changes. However, only 144 PWR spent fuel assemblier are stored. Currently, two of the 6X6 BVR racks are not installed; if necessary, one 6X6 BWR rack may be installed directly, and the other installed after removal of the extra 4X4 PWR rack. As with Unit 1, the current installed capac;ty is less than that allowed by the Technical Specifications.

Future Plans The Company is actively pursuing two options for storage of BSEP's spent fuel. The first is shipment of spent fuel from BSEP to the Shearon Harris Nuclear Power Plant (SHNPP). A request for route approval was

[ approved by the NRC on April 5, 1989 and shipment is expected to begin in July, 1989.

1 The second option is dry fuel storage, which will include construction of 44 Nutech Horizontal Modular Storage (NUHOMS) modules within the BSEP owner-controlled area for storage of the 304 PWR fuel assemblies currently in the BSEP spent fuel pools. Each of the horizontal storage modules will hold up to seven PWR fuel assemblies. A license application for this installation was submitted to the NRC on April 27, 1989. It may be necessary for CP&L to begin site preparation for the installation on February 1, 1990, especially if shipment of fuel from BSEP to SHNPP is delayed or interrupted. Construction would then begin approximately June 1,1990 with fuel loading expected by November 1, 1990.

Once the NUHOMS modules are constructed, the PWR racks currently residing in the BSEP spent fuel pools would no longer be necessary. The Company intends to pursue removing the PWR racks and replace them, as necessary, with 6X6 LWR racks. A license amendment would be required to I reflect the various combinations of BWR and PWR storage spaces to allow gradual removal and replacement of the PWR racks.

Yours very truly,
