Radiological Aspects of PWR Systems
Light water reactors are characterized by the fact that water serves as both the coolant and moderator. Two major types of reactors dominate the LWR industry, the pressurized water reactor (PWR) and boiling water reactor (BWR). This chapter describes those PWR systems of concern to radiation protection personnel while Chap. 3 provides an overview of BWR systems. The primary objective is to present those aspects of system design and interrelationships that impact plant radiological conditions. The function and purpose of various systems are presented along with their associated radiological hazards. System descriptions are provided in sufficient detail to allow radiation protection personnel to assess radiological conditions associated with various plant operating conditions.
