Reference (a): L.R. Greger letter to Cordell Reed dated Pebruary 6, 1990.
Dear Mr. Davist This letter is in resp >nse to the inspection conducted by Messrs.
R. Paul and M. Kunowski November 16, 1989 through January 5, 1990 of the LaSalle County Station Radiation Protection program.
Reference (a) identified certain weaknesses associated with the suppression pool inspection conducted on December 26, 1989.
Although no response was requestad, Commonwealth Edison is submitting the following Attachment to describe the actions which have been taken to address the identifled weaknesses and strengthen the performance in these areas.
Very truly y0urs, t

..,a Inspection Report 374/89023-01 identified weaknesses associated with the suppression pool inspection conducted on December 26, 1989 in which two workers received a small intake of radioactive material while working in the pool. The paragrephs below describe the actions which have been taken to strengthen performance in these areas.
Absentt_Qi_EIDitational_HE_C01trage:
In the above mentioned event the station had Professional Health Physics (HP) involvement during the planning stages and during some portions of the work.
The Health Physics Services Supervisor has since then discussed with both Lead Health Physicists the expectations regarding Professional HP coverage on significant jobs along with the role of the HP.
This role is to provide an oversight function of activities to aid the station Radiatiot Protection Technicians (RPTs) during both the planning and execution phase of the work.
f allutt_in_t akt_s arly_nasalsme ars : As the report indicated nasal surveys were taken to assess the possibility that an intake had occurred. These surveys were performed af ter several decontaminations were performed.
During the weekly communications session with the RPTs, the entire suppression pool event was discussed.
The importance of the need to perform early nasal surveys was emphasized.
In addition to the verbal communications, LaSalle Radiation Procedure (LRP) 1470-6 was revised to require nasal surveys prior to additional decontamination activities unlesn the contamination is due to a hot particle in the facial area. To minimize dose to the skin of the whole body, the removal of the particle will take priority.
failure to _ perform _a_xhole_ body _c.ountLatter repeated f ailures on the day _af the_nysnt: Procedures LRP-1240-25 " Operation and Calibration of the Eberline PM-7 Portal Monitor" and LRP-1470-5 " Identification of Radioactive Particles" were revised in January 1990. These revisions included a brief discussion of the following:
The differences between gatehouse and whole body monitoring equipment regarding primary radiations monitored.
The possibility that a whole body count of an individual may be required when the source of a radiation alarm cannot be located.
A requirement that a Health Physicist be contacted to authorize the release of an individual from site when the above conditions exist.
These changes have been discussed with the RPI's and RP shift supervisors.
