Dear Mr. Vassallo:

In a_ letter dated August 1, 1984 (Serial No. NLS-84-309), Carolina Power &

Light Company informed you of our intentions of submitting an addendum to the Brunswick Plant Unique Analysis Report (PUAR). The enclosed addendum details the approach takca to resolve safety / relief valve (S/RV) second pop concerns at Brunswick. The evaluation shows that the S/RV discharge lines and supports, the torus internal structures, and the torus shell, as modified by the Mark I Containment Program, are acceptable for S/RV load cases C3.2 and C3.3. The methodology employed in the new analyses is the same'as that reviewed by the NRC and approved in NUREG-0661.

Should you have any questions concerning this submittal, please contact Mr. John S. Dietrich at (919) 836-6154.
