On March 14, 2014, the licensee identified Combustible material in the exclusion area in the Torus without a
Transient Combustible Permit. Torus bay 16 had ceiling barrier material crumbling and falling that possibly was asbestos. White Herculite and red tape was used as a catching platform to contain the ceiling material. The exclusion area is large and 3 bays separation exist between the combustible material and the area containing the opposite train. Combustible loading even with the additional combustible material was approximately 11 BTU/square-foot. The addition of combustible material without a
transient combustible permit was contrary to
NCV of License Condition 2.C.4, Fire Protection, requiring implementing an approved
Fire Protection Program (
FPP) as described in the Final Safety Analysis Report as amended. The licensee failed to implement the requirements as specified in their
fire protection program per procedure FP-PE-CC-01, Combustible Control, Revision 1, which required a
continuous fire watch if combustible were to be put in the exclusion fire zone without a permit. The licensee performed a preliminary assessment and concluded that even with the presence of the combustible material in the zone; a fire in the area would not impact both
safe shutdown trains. Therefore, the inspectors determined that the finding was of very-low-safety significance (Green) because of the large separation between the opposite trains. This issue was entered into the licensees Corrective Action Program as
AR 1422495, Combustibles Found in the Exclusion Area in the Torus, dated March 14, 2014. As part of the licensees corrective actions, the licensee added this temporary combustible load to the Combustible Loading Control logs, initiated a Combustible Control Permit and initiated a temporary change to FP-PE-CC-01, Combustible Control, that allowed the Fire Protection Engineer to evaluate the appropriate compensatory measure. The compensatory measure for this instance was
hourly fire watch. The licensee planned to repair and seal the deteriorating ceiling material and then remove the combustible material.
