AREAS INSPECTED:
On-site and in-office inspection by Region I staff, consisting of facility tours, observation of
.
.
work-in-progress, and review of various licensee procedures and reports. Particular attention.--
was given to procedural adherence, radiological controls, surveillance and maintenance, physical plant security, decommissioning activities, housekeeping, and industrial safety.

EXECUTIVE SUMMARY DECOMMISSIONING PLAN Inconsistencies were identi6ed between the Decommissioning Plan, the physical plant condition, and some equipmen' configurations. LIPA had failed to keep the Commission apprised, in writing, of changes that they had made to the proposed Decommissioning Plan that was under review by the NRC. This is an apparent violation of 10 CFR 50.9(a) (Refarence Section 2.0)
ItADIOLOGICAL CONTROLS Radiation controls personnel and general radiation workers were receiving the appropriate training and pre-job briefings prior to commencement of radiological work activities.
The implementation and adequacy of radiological controls practices was sufficient to casure that occupational radiation exposure was kept as low as reasonably achievable.
The licensee frequently used mock ups to test work techniques prior to actual performance of the activity.
(Reference Sections 3,1 and 3.2)
The engineering work associated with the construction and operation of the dry cutting statio:
was good. High ef6ciency ventilation systems were installed to control potential airborne radioactivity. The licensee plans to use a large diameter milling machine for cutting of the reactor vessel (Reference Section 3.3))
SOLID RADWASTE AND TRANSPORTATION The small volume of spent resin generated was placed in polyethylene liners, dewatered, and shipped to a low-level waste disposal site. The bulk of the radwaste shipments consisted of segmented plant piping and components. Reactor vessel internals were sectioned and placed in liners under water, the liners were then transferred into shipping casks. Bulk piping and valves were shipped in SeaVans. The licensee's radweste shipping prograrn and implementation of the program appeared to be generally good. Howev :r, an unresolved item was identified regarding the sign-off of activities associated with a shipment of irradiated control rod blades in advance of performing the required activities. The liccasee's program for assurance of quality in the radwaste area included vendor audits, supplier surveillances, in-plant audits and surveillances.
(Reference Section 4.0)
FIRE PROTECTION / PREVENTION PROGRAM When the fire protection requirements were moved from the Technical Specifications to the Fire Hazards Analysis Report, the limiting conditions and surveillance requirements related the diesel generators, the emergency switchgear, and the batteries were not incorporated. However, this equipment is required to be operable to support fuel handling. This is an unresolved item.
(Reference Section 5.1)

The combustible materials control program was clearly denned and well implemented. The fire.
protection equipment was adequately maintained to support the safe storage of the fuel and in accordance with the licensee's fire protection program. - Housekeeping conditions were generahy _
good. The licensee had developed a program for training related to discovering and reporting nres. (Reference Sections 5.2 through 5.5)
SURVEILLANCE AND MAINTENANCE The inspectors monitored. work-in-progress, reviewed procedures and work packages.
Particular attention was given to procedural adherence, radiological controls practices, and housekeeping. All work observed was in conformance with applicable procedures and met the requirements of the Technical Specifications. Several weaknesses were noted in the area of-industrial safety. (Reference Section 6.0)
_
NRC LICENSED OPERATORS A recent amendment to the Technical Specifications eliminated the requirement for NRC licensed operators in the control roora. The applicable program was reviewed by the inspector and found to be acceptable. (Reference Section 7.0)
