achieved. The design ensures that corrosion and oxide buildup of fuel<br />

cladding and other essential components in the primary coolant system will<br />

not exceed the acceptable limits or the recommendations of the fuel<br />

vendor.<br />

Experience has shown that the pH of the primary coolant can influence the<br />

rate of oxide buildup on aluminum-clad fuel The pH and the proposed<br />

system are consistent with the analysis for the effect of oxide on heat<br />

transfer from the fueL<br />

* The primary coolant cleanup system and its components have been<br />

designed and selected so that malfunctions are unlikely. Any malfinctions<br />

or leaks will not lead to radiation exposure to personnel or releases to the<br />

environment that exceed the requirements of 10 CFR <strong>Part</strong> 20 and the<br />

facility ALARA program guidelines.<br />

* The plans for controlling and disposing of radiactivity accumulated in<br />

components of the primary water cleanup system, which results from<br />

normal operations and potential accident scenarios, conform with<br />

applicable regulations, including 10 CFR <strong>Part</strong> 20, and acceptable<br />

radiological consequence dose limits for accidents.<br />

* The technical specifications, including testing and surveillance, provide <<br />

reasonable assurance of necessary primary water cleanup system operability<br />

for normal reactor operations.<br />

5.5 Primary Coolant Makeup Water System<br />

Areas of Review<br />

During operations at non-power reactors, primary coolant must be replaced or<br />

replenished. Coolant may be lost through evaporation in open-pool systems,<br />

radiolysis, leaks from the system, and other operational activities. Although each<br />

non-power reactor should have a makeup water system or procedure to meet<br />

projected operational needs, the system need not be designed to provide a rapid,<br />

total replacement of the primary coolant inventory. Specific areas of review for<br />

this section are discussed in Section 5.5 of the format and content guide<br />

Acceptance Criteria<br />

The acceptance criteria for the information on the primary coolant makeup water<br />

system include the following:<br />
