- River Band Station - Unit 1 Docket No. 50-458 J
l
'1he final rule for embustible gas control was published in the i
rederal Registar on January 25, 1965. 1he rule requires that a hydrogen control systara justified by a suitable progre of testing and analosis be prtuided in Mark In contalment plants such as River Band Statan.
i The rule also requires that arplicants develop and subnit a proposed schedule for meeting the r@amants of the final rule (10 Cf2 50.44, paragra#4 (c) (3) (iv), (v), and (vi))..
csU is a serber of the Hyd.scen "centrol owners' Gtoup and is I
actively superting ccepletion of the program eIernents described in the EOG Bydrogen Control Program Plan (sukmitted to the NBC cn Decenbar 14, 1985). GSU's proposed sd.edule for ocnplying with the hydrogen sula i
it applies as to the River Bend Station is attachsd. This schedula shcWs i
sv,osed carpletien dates for the generic tasks as well as River Band l
Station - specific activitias. As shown, a 3 control systsm for l
the River Ban (Station has been designed, inst
, and tested.'

'1ha final rul' also requirs.1 that analysis dich suppcrts the design s

2he schedule s q lied herein satisfies the requirements of 10 cm 50.44 (c) (3) (vii). It a.%21d be noted that this schedule has been
- developed based upon tentative agrements with the N7c staff crt the Hydrogen Control owners' Group program tanks.' If any changes in the scope of these tasks are required by the, staff, this schedule may require revisierJ.
