The application should include a clearly defined chemistry control program that states the goals and objectives of the program. The program should:
The applicant should describe the approach, based on industry research- and operating experience, that will be used for the chemical control of reactor facility fluid systems important to safety during construction and commissioning, and at a programmatic level for operational states.
The application should include sufficient information and provide references to detailed documents to demonstrate how chemistry program objectives will be achieved during construction and commissioning activities and operation. Some examples that the information should address are:
The applicant should demonstrate that the chemistry control program establishes processes and overall requirements for effective control during commissioning and operation and under lay-up conditions to ensure critical equipment performs safely and reliably over the requested licensing period. The application should include a set of technical basis documents establishing the design basis for chemistry control.
The applicant should demonstrate that a chemistry surveillance program is established and implemented to verify the effectiveness of chemistry control in all systems. The surveillance program should be used to detect trends in parameters and to discover and eliminate undesirable effects and consequences of out of range chemistry parameters.
The applicant should demonstrate that consideration is given to the use of online monitoring of control parameters as the preferable monitoring method for evaluating chemistry conditions in all systems. The applicant should demonstrate that a calibration and maintenance program is established and applied to all online and laboratory monitoring instrumentation. The applicant should demonstrate that redundancy or equivalency of laboratory facilities is provided to ensure analytical services at all times.
The applicant should demonstrate that the chemistry control program includes defined chemistry specifications for systems; procedures for chemistry parameter monitoring, trending and monitoring activities; and procedures for the storage and handling of chemicals.
The application should describe provisions for a post-accident sampling system or other adequate sampling facility. If one does not exist, the applicant should describe the other approaches that have been adopted for core damage evaluation and for estimation of the inventory of fission products released into containment.
The applicant should demonstrate that the operating organization has procedures for chemicals and for controlling their required quality. The application should include lists of approved chemicals.
The applicant should demonstrate that the chemistry control program includes procedures for selection, monitoring and analysis of chemistry regime, instructions for operations involving chemistry processes and evaluation of operating results, the operation and reference limits for chemistry parameters and action levels, and possible remedial actions, including ensuring that the chemicals and their quantities used are correct.
The application should include a timeline and milestones for the development and implementation of the remaining matters related to chemistry control.
