50-316 89013 DRSS Areas Ins eWed:
Routine, announced inspection of the following areas of the ona d
.
ook Nuclear Power Plant emergency preparedness program:
action on previously identified'items (IP 92701);
knowledge and performance of duties (IP 82206);
and dose assessment (IP 82207).
The inspection involved one inspector.
Results:
No violations of NRC requirements, deficiencies, deviations or open
>tame were identified as a result of this inspection.
The iicensee has developed a computerized Dose Assessment Program.
All personnel who are designated members of the Environmental Assessment Group had completed training and adequately demonstrated their expertise in implementing the program.
This program gives the personnel in the group the capability to update the State and County officials every 15 minutes as the State has requested.
Dose assessment and protective action recommendations were a weak area in'he licensee's Emergency Response Program which they have successfully upgraded through revised procedures and additional training of personnel.

Licensee Action on Previousl -Identified Items (IP 92701)
(Closed)
0 en Item No. 50-315/88022-01:
The first dose assessment progectson calcu atlons performed urging the exercise resulted in erroneously high thyroid doses due to a personnel failure to convert monitor readings to the correct values for input to the dose assessment computer evaluation and review.
Personnel did not recognize that the thyroid doses and source term did not correlate.
These erroneous values resulted in excessively conservative Protective Action Recommendations (PARs) to the State.
The licensee has developed an improved dose assessment program for use on PCs located in the Control Room, Technical Support Center, and the Emergency Operations Facility.
Licensee personnel adequately demonstrated the program and associated procedures during a drill on March 27, 1989.
This item is closed.
Trainin (IP 82206)
and Protective Action Decisionmakin (IP 82202)
A review of Radiation Protection and Dose Assessment training was conducted.
Lesson plans were adequate in scope and objectives and included training on meteorological conditions, radioactive release data, classifications, dose rates, plume dispersion, release duration and source terms'raining consisted of classroom instruction, comprehensive hands-on training and written task oriented exams.
Records indicated that all plant personnel assigned to Emergency Response Organization dose assessment responsibilities were trained.
All members were cross trained and capable of performing in any position in this area.
Corporate staff who are responsible for these duties were also trained.
A.training drill conducted March 27, 1989 was successful.
A mini-scenario was implemented by a response cell in the Technical Support Center.
The EOF partially activated; along with full activation of dose assessment personnel.
Staff members adequately demonstrated a thorough knowledge of dose assessment equipment and procedures.
Correct protective action recommendations (PARs) were developed at both the Site Area Emergency and General Emergency classifications.
The staff also demonstrated their capability to develop 15 minute updates for the State and counties.
Personnel were cognizant ef plant parameters and incorporated these into their PAR development proces Based
.on the above findings, this portion of the licensee's program was acceptable.
Dose Assessment (IP 82207)
A review of Offsite Dose Projection Procedure (PMP 2081 EPP.304)
was conducted.
The procedure was consistent with the dose assessment model implemented during the March 27, 1989 drill.
Capabilities exist to project doses from ground level and elevated releases, and monitored and unmonitored pathways.
Feedback from field teams could also be incorporated into the program.
The program model reflects the State Event Notification Form from the State of Michigan.
Meteorological data is obtained from installed site equipment.
Offsite doses are calculated and protective action recommendations are also calculated.
Doses are calculated for site boundary, 2 miles, 5 miles, and 10 miles.
Protective action recommendations are recommended for both sectors and miles and include evacuation, in-place shelter, contamination control, and KI distribution.
A review was conducted of personnel performance using dose assessment procedures, forms, and equipment during a training drill on March 27, 1989.
Personnel were well trained and know'ledgeable of both the computer model dose assessment program and the backup calculator method.
All personnel were cross trained on all positions associated with dose assessment.
At the time of this inspection the Dose Assessment model is available in the TSC and EOF.
A PC has been purchased and placed in the Control Room for future use.
Personnel will be trained to use the Dose Assessment program.
All three main facilities will then have this capability to perform dose assessment.
Based on the above findings, this portion of the licensee's program is acceptable.
Exit Interview The inspector held an exit interview on March 28, 1989, with the representatives denoted in Section 1.
The licensee's training program for dose assessment was well developed and all personnel were trained and successfully 'completed required exams.
The Dose Assessment Program met all inspection requirements.
The licensee understands the emergency classification system and emergency action levels and demonstrated a
thorough knowledge of protective action recommendation criteria.
The licensee indicated that none of the information discussed was proprietar 'V>>
