Youngblood to D. L. Farrar.
Dear Mr. Denton:
This letter provides the response to an P C question regarding the Byron /Braidwood volume reduction systems. This information will be incorporated into the FSAR at the earliest opportunity.
Enclosed is the response to question 321.104 which was sent to us in reference (a). The responses to questions 321.100 and 321.103 will be provided later this week. Please direct further questions regarding these matters to this office.
One signed original and fifteen copies of this letter and the enclosures are provided for your review.
Very truly yours,
$/2,1%

O QUESTION 321.104 The response to Question 321.78 should be expanded to provide additional information about the training given to operators of the Volume Reduction (VR) System. We currently believe that these operators should be dedicated to the operation of the VR system.
If you disagree, provide your plan for assigning operators to the VR system and your justification for this plan.
Response
The volume reduction system (VRS) will be operated only by Commonwealth Edison bargaining unit personnel permanently assigned to the plant.
Adequate training and supervision will be provided to assure that this equipment is operated correctly.
At Byron and Braidwood, Operating Department personnel with the title of Equipment Attendant (EA) will manipulate the controls of the VRS. As described in Section 13.1.2.2 of the FSAR, EA's are the only individuals authorized to operate local system control panels in the plant. The FSAR describes the general qualifications and training programs for these individuals.
The Shift operating personnel are divided into six shifts. Each shift normally has eight EA's.
Two of these EA's will be routinely assigned to operate the radwaste systems for a week at a time. On the average, they will spend 25% of their time in the plant on radwaste operations. This assignment includes operation of the VRS, the evaporators, the radwaste solidifications systems, and the related storage tanks and transfer pumps.
While the EA's are assigned to radwaste operations they are under the direct supervision of the Shift Radwaste Foreman. The Radwaste Foreman assignment is not routinely rotated among the shift foremen. Individuals are assigned to the Radwaste Foreman position on a continuing basis to provide consistent oversight and special expertise on shift in the operation of the plant radwaste. systems. This staffing approach was developed at Commonwealth Edison's four operating nuclear generating stations and has been demonstrated to be effective over the past several years in the operation of similar radwaste systems such as evaporators and demineralizers. Rotation of job assignment helps develop the pool of personnel from which licensed operator candidates are chosen. It also helps equalize the occupational exposure to operating personnel.
Day-to-day operating activities associated with radwaste are normally overseen by the Unit 0 Operating Engineer who deals only with the operation of plant systems that support the operation of the two reactors.
Radwaste system operations and maintenance get the bulk of his attention.
He is assisted by a water management and radwaste coordinator who tracks the performance of radwaste systems and coordinates the modification and upgrade of radwaste systems when necessary. Engineering personnel are also available on the Technical Staff to-test and troubleshoot specific hardware problems.
Experience at the four other Commonwealth Edison operating nuclear stations has demonstrated the adequacy of this level of oversight of radwaste operations.
Vj q,~ ;
_2-Before an EA is permitted to operate the VRS, he will receive specialized classroom training,' hands-on training on operating procedures, and an individual checkout by one of the radwaste foremen. EA's are usually selected on the basis of aptitude from the pool of people.in the entry-level operating department job category. The general training program for EA's is described in FSAR Section 13.2.1.5.
The VRS classroom training for EA's consists of approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />
- of-: lectures and self-study. Operators are trained on-site to understand the
-processes involved,-the critical. parameters, the operating characteristics
..of the various components, the instrumentation and controls, and the basic
- operating procedures. -This_ training. program was developed on the basis of the initial training provided by AECC at the Byron site. Video-tapes of the.
initial program are-available for use at the discretion of the instructor.
(Written. tests demonstrate the EA's mastery of the information. _ About 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> of hands-on-training on operating procedures are also provided in the.
plant by a Radwaste Foreman. An EA is not considered qualified to operate the VRS until he has satisfactorily completed the individual checkout by a c
.Radwaste Foreman'in'accordance with_the certification guide. He is not permitted to operate.the system along until he has been so qualified. All
.of the individuals who direct operation of the VRS as _Radwaste Foremen
~
during the_ initial. operation of the VRS are trained by AECC and participated in the initial testing of the VRS.
3
- The VRS will be operated by the EA's as instructed by the Radwaste
- Foremen and in accordance with approved operating procedures. Deviations fram these_ detailed-procedures are not permitted without the foreman's
. concurrence.-
.In summary, the general approach to staffing and training for radwaste
. system operation-does not need to be ' modified for operation of the VRS.
Careful' design _means that; operation ~of this equipment will be no more complex or hazardous than any'other nuclear power plant equipment. 'As with
'all radwaste equipment, special care will be taken_in the supervision of VRS.
. operation because successful, error-free ~ operation is important.. The present approach to staffing.and training is adequate'to assure that all EA's can be.
' properly qualified to-operate-the VRS safely under the. direction of dedicated radwaste foremen. There is no reason to impose further restrictions upon gy
- the number of individuals, authorized to operate VRS.
