The reactor vessel and head storage shield plugs, the wooden cover over the fuel storage pool, and the locked covers for the personnc3 and equipment hatchways remain in place.
J III.
RALMTION ANJ CONTAMINATION Complete radiation and contamination surveys of the facility indicate that s
the levels remain low.
Survey renuits are tabulated in Table 1.
The radiation / contamination levels listed are representative but not necessarily maximum values.
IV.
ACTIVITIES Routine inspections were conducted during this report period.
