II. Leading Circumstances Following secondary chemistry analyses results ' indica:      e of primary-to secondary leakage, a bubble leakage test was applied          .Y.e Once Through Steam Generator tubing with nitrogen pressure applied         r     the secondary side.
              !!!. Descriotion of the-Occurrence OTSG Tube leakage was initially suspected when OTSG-I          . ple results showed decreasing pH and increasing activity.        These      : oms appeared following Reactor Coolant Syste's pressurization to at          ;5 psig for functional testing. The functional testing program v       then aborted and the Reactor Coolant System depressurized and parti        ly drained in preparation for bubble leak testing to locate the tub. t.: tubes which were leaking. Primary-to-secondary leakage with the RC Syr*.:c pressurized to about 45 psig amounted to about 0.2 to 0.3.gpm.
Initial bubble testing indicated about 27 leaking tubes in the "B"            OTSG, the steam generator whose secondary chemistry indicated primary-to-secondary leakage when the Reactor Coolant System was pressurized to about 45 psig. A later bubble test on,lp28/81        identified cleven additional leaking tubes in the "B" OTSG.-
Subsequent bubble tests in the "A"'-0TSG identified 88 tube leaks in that OTSG.                            ,
The event was considered reportable per Technical Specification 6.9.2. A(3).
IV .- Anv Significant Events Which Hapnened as a Result of the Original Occurrence                   .
Kone V. Previous Events No previous OTSG 1eaks.
VI. Root Cause of the Occurrence Detailed investigations into root cause are now in progress and are presently inconclusive.                                                                   .
VII. Immediate Corrective Action
~
Since the unit is in a cold shutdown condition, im e'             corrective action
     -                was to depressurize the Reactor Coolant System and c           in the contaminated secondary fluid.:
VIII. Long' Term Corrective Action.                                    .
Present investigations are continuing to identify th'         et cause for the tube leaks which presently seem to be concentrated ic             Upper Tube Sheet region of the steam generator tubing.

You have requested that we provide you with the offsite radiological impacts when the plant suffers an iodine spike followed by a large tube leak in the OTSG.
According to Ref. 1, the detector reading of 3500 cpm on the steam line radiation monitors (RM-G26/G27) would result in the 250 mr/hr offsite thyroid dose assuming no iodine spike occurred. With the unrealistic assumption that all the count rate is due to an iodine spike, the 3500 cpm of the RM-G26/G27 reading would correspond to approximately 1.3 rem /hr thyroid dose at the exclusion boundary. The key assump-tions used in this scoping analysis are :    (1) 30 lbs./sec._gteam rglease through the Atmospheric Dump Value (ACV); (2) X/Q-value of 6.8 x 10 sec./M ; and (3) 100%
iodine activities in the steam line (Ref. 2).

HIGH RANGE RMS DOSE CALCULATIONS' Section. A   System Description The High Range RMS is categorized into' three distinct subsystems (See                                                                   .

: 1.    -Radiciodine Processor Stations
: 2. Containment Air Sampling
: 3. High Range Noble Gas Channels       .
Subsystem (1):
Radiciodine Processor Stations Three stations allow samples to be obtained independent of radiation monitors                                                                   ;
RM-AS, A8 and A9. The stations are controlled by solenoid valves which
:-       actuate flow through one or more of the (3) parallel filter cartridges per station. Thii sampling times for each filter cartridge are adjustable on each
  ~*
local control panel. The filter cartridges must be manually removed for analysis.
Subsystem (2):
Containment Air Sampling The post accident RB atmospheric sampling station is located at_ the 322' level of the intemediate building, one floor above radiation monitor RM-A2.
                                                                                                                                                        -I Three-way ball valves are installed in the RM-A2 sampling lines downstream of containmen.t isolation valves. The sampling lines are connected downstream of CM hl, CM-V2, CM-V3 and CM-V4 at P-108'.

UNIT NO. 1 EMERGENCY PLAN IMPLEMENTING PROCEDURE 1004.7 0FFSITE/0NSITE DOSE PROJECTIONS

==1.0 PURPOSE==
The purpose of the procedure is to provide:
: a.      Techni@es and methods for calculating projected doses (wlole body, and ttyroid dose e@ivalent which might result from monitored releases of radioactive materials from TMI Unit 1.
: b.      Tectni@es and methods for predicting the downstream concentrations of radioactive lipids resulting from a major accidental release of radioactive liquids to the Sus @ehanna Valley.
: c.       Contingency methods for estimating projected doses if monitors are out of service or off-scale high.

Comment:. This-paragraph gives the impression that a 22" expansion was performec-in each tube. As
                                                  . discussed in TR-008, a 22" expansion was used for tubes where the lowest defect was too' low to
* be repaired by a 17" expansion.

Coment: The thiosulfate tank has been physically removed from communication with the reactor coolant system by cutting the connecting lines and sealing them with blind flanges, but the tank ,
has not been physically removed from the plant.

Comment: As discussed in our June 6 update to LERs 82-11 and 83-03, the PORV internals and safety relief
                                      .            valves were replaced. The PCRV body was cleaned and inspected,-then returned to service. The

Response:        The Delta T limit in the procedure is 700F. If this limit is approached the guidance in 1202-5 does require that the cooldown rate be reduced
     ~
or secured so as not to exceed 70aF. The guidance for a 1000F Delta-T has been removed          e from TDR 406, Rev. 2 (see abstract and section 3.2.2.3 of TDR 406, Rev. 2). It should be

Comment: The' numbers of tubes listed in the last.two columns are approximations only. In some cases more were done in the baseline and will be repeated after 90 cays. In some cases fewer were done because the' population of tubes in that category was less than shown in the table due to plugging of adjacent tubes or the tubes                                                         !
