~RESPONSE TO

.

IE CIRCULAR NO. 76.

IE Circular No. 76-03 requested that a number of specific actions be taken to ensure that there are prop~r controls to prevent overexposure events due

~

to entry into existing or potential high radiation areas. The control measures must .be adequate to ensure that transient changes in the exposure rate do not occur while personnel are in the affected area. The actions requested by the Circular have been completed at Quad-Cities Station.

I tern l:

. I A thorough review and inspection of plant operations and areas was performed to locate a~d identify all transient and continuous high radiation areas.

This review involved a visual inspection of all plant areas, a review of past radiation survey information, and a compilation of those areas known to display transient changes in exposure rates. For.this review, transient and continuous high radiation areas were considered as those defined by 10CFR20.202(b).

Item 2:

_The above inspection of plani areas involved ~erifying that all high radiation

~reas are properly posted, locked, and controlled, in such ways that the nature of the hazard is clearly and specifically identified, entry into the area is prop~rly restricted, and suitable surveys prior to entry are conducted. All signs identifying high radiation areas are conspicuously placed. The inspection confirmed that all high radiation areas are properly posted.

Item 3:

The radiation protection procedures, including the station administrative procedures, and the radiation protection training and retraining programs effectively deal with the matter of entry into high radiation areas and, the access controls placed on such areas. All station personnel receive periodic retraining in the pertinent aspects of radiation protection, in-cluding entry into high radiation areas.

Item 4:

Prior to personnel entry into high radiation areas, adequate management review and approval must first take place. This review ensures that exposure rates within the area are known, and that they will not undergo dramatic changes while personnel are within the affected area. The station admini-strative procedures for drywell and high radiation area entry and the 11 R11 key procedures provide the necessary controls.

Item 5:

The controls necessary to provide the assurances described above are con-tinuously reviewed and audited as part of the routine activities of the station radiation protection depa~tment. The effectiveness of the controls is assessed by.the station health physicists. Suppl~mental controls are implemented as they become necessary.

Item 6:

Records pertaining to the above are available for NRC review at the station.
