b APR 2 21977 Toledo IMison Company requirer.ents apply only to selected valves and pumps that can be tested witnout placing tne plant in an unsafe condition. You sbould exercise care in planning your testing progra:s to ensure that no test will ce conaucted wnlle tne plant is in an operating : node tnat woulo make it vulneraale to a test error or a test failure. Particular attention should be directed toward tne valve exercising (cycling) rests.

In this regard, some baalc guidelines for excluding exerciaireg (cycling) tests of certain valves during plant operatica are contained in.

Valve leakage tests and otner valve and pung tests required by the ASdC Code should ce reviewed for eacn eccpenent, rela-tive to each plant operating =ade, to assure tnat no test will nave an a:: verse 1::qnce on plant safery.

If you have any furtner questions regarding inplementation of 10 CFR 50.55a(g) at your facility, please contact us.
