sECTIoN III: CCHMENTS/CONCI.USIONS This surveillance was conducted on Survey Unit No. SUO29, the Main Turbine. Several survey locations were verified as part of Survey Unit No. SUO29. During this surveillance it was observed by the inspector that contrary to the Health Physics Control requirements for termination survey of a " Clean Area" SP 61X010.03, the following items were observed: A station worker did not perform a hand and foot frisk prior to entering a Health Physics clean area. Scaffolding materials were not frisked and cleared by Health Physics personnel prior to entering the Health Physics clean area. Health Physics issued a Radiological Incident Report related to the above mentioned occurrence, Note RIR No. 93-03. Additional technicians involved with the Termination Survey of the Main Turbine are as follows: F. Raitch, R. Schwamsky, W. Smith, R. Matarese, P. Daily. All other areas and attributes related to the termination survey of the turbine were verified as being conducted satisfactorily. );Qf EtI/;WEER/ SPECIALIST 'DATE " APPROVED BY ' ENTE f 'O
