RACKGROUND Waste Management Activities has redefined the changes necessary to resolve concerns on the Epicor II Air Radiation Monitoring / Sampling System. A need has been established to continuously record the gaseous effluent flow rate through the HVAC discharge duct. In addition, the " Return Sample Line" discharges to the atmosphere at 307' elevation. This needs to be justified or routed to the HVAC Duct for adequate dispersion. CON [LUSION Waste Management Activities has concluded that the following items be effected: 1. A HVAC discharge duct flow rate strip chart recorder be installed. 2. The present " Return Sample Line" discharge location be justified or rerouted to the HVAC Duct. 3. The details of the changes, outlined in the DISCUSSION, be incorporated. DISCUSSION Waste Management Activities (W.M.A.) has met with S. Ewald (NRC-I&E) and G. Lodde (Porter-Gert ) to resolve concerns with the Epicor II Air Radiation Monitoring / Sampling System. On July 26, 1979 a W.M.A. memo was sent to Burns and Roe to incorporate several changes to the Radiation Monitor / Sample System (See Attachment #B). Since that time the recommended changes have been re-evaluated. This memo was written to document the necessary changes that will satisfy the above concerns per the following criteria: 1. QA/QC, Tech Spec Code Federal Regulations or Licensing Requirements, 2. Epicor II Operational Requirements, 3. Good Construction practice and applicable engineering codes ( i. e'. A.S.M.E. Code) and 4. Cost / benefit analysis. The details of the changes incorporated are outlined below: a. A stripchart flow rate recorder needs to be installed to continuously track the HVAC discharge rate. b. The " Return Sample Line" (Attachment #A) is presently routed through the HVAC Building wall and discharges to the atmosphere near ground level. This situation needs justification from an environmental standpoint and a drawing change to reflect "As Built" conditions. 2220 !)38 O

If the " Return Sample Lir.e" discharge point is not in compliance with c. current requirements (Unit II Tech. Spec., 3&R design criteria), please extend the tubing and connect to the HVAC duct. This will ensure the sample line effluent be adequately dispersed from the HVAC Stack. Please revise B&R Dwg. M013 Rev. to reflect change. REFERENCES (* Attached) 1.

Sumect Modifications to Epicor II (WG-2) Air Radiation Monitoring / Sampling System Three Mile Island To Locar.on W.M.A. BACKGROUND Waste Management Activities has met with S. Ewald (NRC-I&E) and Gordon Lodde (Porter-Gertz) to resolve concerns with the Epicor II Air Radiation Monitoring / Sampling System. Per en-suing discussions, a need has been established to correct un-satisfactory "As-Built Conditions" to the original Burns & Roe Engineering Change Memos and Drawings. The " grab sample line", recently installed to comply with original E.C.M., must be re-installed without a 90 connection. Recommendations were made to eliminate unnecessary bends in the sample ' ine and reduce 4bc length of horizontal run, optimizing the mon.. tor / sampler effi-ciency. In addition, a continuous flow rate recorder was suggested to consisterfly track gaseous ef fluent discharge. CONCLUSION Waste Management Activities concurs with correcting air monitor / sampler "As-Built Conditions" and air sample line rerouting. Please initiate necessary E.C.M. or E.C.M. Change to effect the modifications outlined above and detailed in Discussion. DISCUSSION The following modifications need to be made to ensure optimum efficiencal of the Air Radiation Monitor / Sample System: 1. Reduce all unnecessary air sample line lengths horizontal 3 runs 3and bends. a) Relocate sample point location off HVAC Discharge Duct as low as possible, observing criteria of Isokinetic nozzle. If necessary, re-evaluate with W.M.A. b) Reduce length of horizontal run by locating sample point on South side of HVAC duct as well as sloping any horizontal run to deter particulate deposition. In addition, the sample line may be installed on North side of monitor / sampler unit to reduce length. c) Eliminate unnecessary sample line bends and increase angle of necessary b' ends (especially greater than 90 ). 2220 342 CPU Serece Cerccrat.cn :s a tutsc. arf of Gecerai P tiic Ut les Ccr; craton

Install air sample return (e f fluent) line downstream of sample point location off HVAC discharge duct. See Attachment #2 for detail. 4. Obtain the operating HVAC discharge flow rate (C. F.M. ) and ensure a 1-3 C.F.M. flow rate in the sample line to the Radiation / Monitor / Sampler Unit. 5. Install a continuous flow rate recorder (i.e., strip chart record) in addition to the existing flow rate indicatar for HVAC discharge. 2220 343 6 e O m e - +

A preliminary evaluation of the air monitoring system for EPICOR II revealed the following deficiencies: @. There is a n.ed to ' heat trace the sample line from the sample r to the constant air monitor for vinterization. This is required -~ to =inisins the platc sut of iodinc i:. th: ::=pic linc &ains the vinter. b. There are at least four unnecessary bends.nd about a 15-20 foot horizontal segment in the sa:nple line after it enters the building and prior to reaching the constant air monitor. The poor location of the constant air monitor vill result in an undetermined loss of particulates and iodines in this part of the sample line. @ There is a need for a valve assembly to be installed in the sample line near the constant air monitor to obtain both gas and iodine species samples. d. There is a need for a direct readout for both sample flow rate and effluent flow rate near the constant air monitor. This type of readout will minimize the error associated with determining p essure drops and interpretting flow rates from cha:ts or Eraphs. There should also be a recorder for effluent ficv rate. 2. The above noted deficiencies should be corrected in order to more accurately assess the release of airborne effluents to the environment from EPICOR II. l / S1s n P1 Syd Porter, Jr.
