in waste containers can also lead to container breach and potentially inflammable or explosive conditions. To minimize the number of potential problems, licensees should evaluate the potential for gas generation, gas generation rates, results of radiolysis, biodegradation, or chemical reaction with respect to container breach and the creation of flammable or explosive conditions. Unless storage containers are equipped with special vent design features that allow depressurization and collection of gases (in preventing the migration of radioactive and combustible gases into ambient areas), spent resins loaded with significant inventories of radioactive materials should not be stored for longer than approximately one year. Licensees should implement a program providing for at least periodic (quarterly) visual inspections of container integrity (e.g., for indication of swelling, bulging, generation of corrosion products, leaks, or breach). Inspections can be accomplished by the use of television monitors; by walkthroughs if storage facility layout, shielding, and container storage array permit; or by selecting waste containers that are representative of the types of waste and containers stored in the facility and placing them in a location specifically designed for inspection purposes. All inspection procedures developed should minimize radiation occupational exposures using the guidance in RGs 8.8 and 8.10. The use of HICs (300-year lifetime design) would permit an inspection program of reduced scope, while recognizing that because of likely elevated external radiation levels, inspection procedures may require additional cautionary instructions. 3. If possible, the preferred location of the additional storage facility is inside the plant’s protected area. If adequate space in the protected area is not available, the licensee should place the storage facility on the plant site and establish both a physical security program (fence, locked and alarmed gates and doors,
