==Subject:==
Response to Allegation Concerning Radiation Protection Practices
 
==Dear Mr. Davis:==
 
Nuclear Regulatory Commission (NRC), Region III letter dated July 1,1988, forwarded an allegation, #RIII-88-A-0050 concerning Radiation Protection Practices at Clinton Power Station (CPS), to Illinois Power Company (IP) for investigation. The IP Quality Assurance Department has completed this investigation, and the results are summarized in Attachment A to this letter.
Please contact me if you have any questions regarding this information.
Sincerely yours.

: 1. The allegation stated that on occasion, health physics technicians in the plant have improperly deleted Radiation Worker Permit (RWP) protective clothing requirements without modifying the RWP. A specific example was provided.
 
===Response===
This allegation has been substantiated. The specific example stated fu the allegation could not be identified; however, a similar condition was identified on April 21, 1988.
The investigation concluded that, as required, RP technicians had been reviewing radiological cc.nditions for changes, but had not always been completing the administrative function of modifying the RWPs accordingly. To correct this problem, on June 19,~1988,1a Radiation Protection Operations Night Order was issued'to'RP"shift supervisors and RP technicians reinforcing the administrative functions required to be completed when changing radiological protective requirements.
While the allegation has been substantiated, it is important to note that radiological control procedures requira that each individual obey posted, oral, and written radiological control e                    instructions and procedures, including instrw tions on RWPs.
Additionally, each individual shall not deviate from the requirements stated on the RWPs unless directed to do so by RP personnel.
: 2. The allegation stated that the physical flowpath of personnel through the three frisker monitors located at the exit of the Radiologically Controlled Area (RCA) was conducive to personnel cross-contamination because the three monitors were physically aligned such that individuals leaving the monitors walk across the g                    path of individuals waiting to be monitored.
Responses i
I                    This allegation has been substantiated. Investigation revealed
;                    that because of the physical location of the radiation monitors at the RCA exits, the potential exists for cross-contamination of personnel >
The Assistant Manager - Plant Radiation Protection is evaluating meth+ds for relocating the radiation monitors at the RCA exits to prevent the potential for cross-contamination. Recommendations for improvement will be provided to the Manager - Clinton Power Station Lby August 31, 1988. y

IP's review of this condition determined that it has no significant impact on the Radiological Control Program.      Radiation monitors located at the exits of the Prctee'.ed Area will identify personnel who have passed through the RCA exit monitors and subsequently become contaminated by crossing the path of a contaminated person. Additionally, RP conducts routine radiological surveys (smears) of the power block entrance, the lunchroom, the operations gate house exits, and the craft security portal exits uhen in uso. These routine surveys add assurance that contaminated personnal are not exiting the RCA.                        !
: 3. The allegation stated that hand held friakers were not located near step-off-pads from radiologically contaminated areas.      The example given was that no frisker was located on the 824-foot level of containment; the nearest frisker station was located on the            -
737-foot level of containment.
Responses This allegation has been substantiated. Investigation revealed that a frisker was not located at the 828' elevation personnel airlock; a frisker has since bcan placed at this location.
The investigation further revealed that prior to receiving this        -
allegation, a concern had been expressed about friskers not adequately identified or located for egress from contaminated controlled areas. An evaluation of this concern and                    !
recommendations to the Manager - Clinton Power Station for            i imptovements will bel completed-by August 31 1988. 7                  !
IP's review of this condition determined that it has no significant impact on the Radiological Control Program. Personnel are responsible for notifying RP when contamination is detected or suspected. It is routine practice for RP to survey the path of the  !
contaminated individual if the individual had to travel to a frisker. If an individual alarms a radiation monitor while exitir.g the RCA, RP is notified and conducts radiological surveys of the      }
path of the individual.                                                ;
i 4  The allegation stated that several personnel contaminations had occurred recently involving localized skin contamination. Rather than decontaminating the localized skin area, the individuals were deconttminated by showering, which could reruit in the spread of contamination over the body.
 
===Response===
This allegation could not be substantiated. The investigation    i concluded that IP has adequate procedures in place to decontaminate  ,
personnel. The review of Personnel Decontamination Records for        l May, June, and Jcly did not identify any instances of improper decontamination.
 
        ** .'                              ATTACHMEFT A Illinois Pow 2r Comptny Clinton Power Station Summary A collective analysis of the substantiated allegations has determined that these conditions do not significantly impact the Radiological Control Program. As a result of the allegations however, evaluations are being performed to determine possible methods for improvement in the noted areas. The Radiological Control Program, as implemented to date, has been demonstrated to fulfill its function in providing a high degree of protection to the employees at CPS.
Supporting documentation providing the details of this investigation has been compiled and is available at CPS for NRC review.
