(PT-37.5 CONTAIRKNT RECIRCULATION FANS HASS AIR PLO'rl CHiCK PT-37.5:1 1.0 PURPOSE: To determine total air flow through Containment Recirculation Pans.2.0 TEST REQUIRE>lENTS:

2.1 Determine

mass air flow of each containment recirculation fan during nornal operation and"A" g"C" fans during accident operation.

3.0 REFERENCES

3.1 Tech.Specs.Section 4.5.2.3.4.0 INITIAL CONDITIONS:

4.1 Ensure

that all fans except that fan undergoing the flow check, are not operating.

This procedure is divided into 6 sections.Indicate which sections were used and mark remainder N/A.4.2.1"A" Containment Recirculation Fan Normal Conditions Hass Air Flow Check.4.2.2"A" Containment Recirculation Fan Accident Conditions Hass Air Flow Check.4.2.3"8" Containment Recirculation Fan Normal Conditions Hass Air Plow Check.'4.2.4"C" Containment Recirculation Fan Normal Conditions Hass Air Flow Check.4.2.5"C" Containment Recirculation Fan Accident Conditions Hass Air Flow Check.4.2.6"D" Containment Recirculation Fan Normal Conditions Hass Air Flow Check., 4.3 Test personnel are qualified in accordance with A-1102.5.0 , 5.1 PRECAUTIONS:
