'I Amendment No. 3 to License DR 10, Docket 50183, issued June 11, 1976. In thin twentieth annual. report, a summary is presented as to the status of the ' facility for the period frok January 1,1987, to December 31, 1987, as required by Paragraph 3.E.2. c ' the license.  ;

I.

SUMMARY

The facility remains in essentially the same condition described in the 3 nineteenth annual report. Entry into the containment building was made for routine radiation surveys and a general check of conditions throughout the l building. Radiation levels remain essentially unchanged.

t II. # STATUS OF THE EACILITY Access to the containment building is controlled by the facility suporvisor according to written procedures. The reactor vessel and head storage shield plugs, the wooden cover over the fuel storage pool, and the locked covers for l

1 the personnel end equipment hatchways remain in place.

i a

III. RADIATION AND CONTAMINATION Complete radiation and contamination surveys of the facility indicate that l the levels remain low. Survoy results are tabulated in Table 1. The (

radiation / contamination levels listed are representative but not necessarily j maximum values.
