1 Introduction This report presents &"1 evaluation of the unit costs of the 13 decontaminaLion tedmiques considered within the LCiviT iviodule of RODOS.

Two major sources of information have been used for this evaluation and \vi!! be described in detail:

  • A RIS0 report of 1995 describing the "Practical Means for Decontamination 9 Years after a Nuclear Accident" r11.
  • A NRPB report or 199() concenling a "Review* or Decontamination and Clean-up Techniques Cor Use in Ihe UK Coiiowing Accident Releases oCRadioaclivily 10 Ihe Environment" L2j.

Moreover, a table of data from NRPB ~.;:tracted from a 1999 report on "Revie't'Y of data on decontamination and remediation techniques for Plutonium and application ror CONDO" l3J, is also presented in the synthesis section.

The unit costs ot aecontammatlOn techmques obtamea by these three reports are sometimes very different It has then been proposed to use the last table provided by NRPB L3J to full" the data base lor the ECONOM module. However, it appeared to be important for RODOS users to be aware that, depending on the hypothesis or on the countries, the data could vary a lot The aim of this report is to give as much details as possihle on the different a.';;sumptions made in the evaluation of costs, so as to provide a guide for users 10 adapt the default data base to their ovm data.

04.08.00 OAGI0001550_00005

2 The main hypothesis The RIS0 Report [11 presents the main features of around 60 decontamination techniques. The main elements presented for each technique and used for the cost evaluation are:

  • Name of Too!
  • Target surface
  • Design (productivity)
  • rvlode of operation
  • Costs Manpower (days/unit area). tool investment cost (EURO),

disCOLLf'lt cost (EURO/year), consumab!es (unit), scale of application.

The l'\TR~PB repOit or 1996 l2 J presents the total cost of several decontamination techniques to be used in urban areas. As pointed out in this report, "the COSTS include: lahour COSTS. COSTS TO hire or depreCIatiOn costs for plant and vehicles. cost of consumahles, runnmg cosfs including maintenance, and cosfs [0 reinstate huildings, roads, elc. ajier deconlamlnallOn. Cosls fiJI' replacemenl of planl are nol tnciuded 111 Ihe overall cos Is. The cosls o(wasle disposal, II1ciudll1g Ihe rransporr or waste, have nor been included". Moreover. in the Appendix of this report. the detailed cost of some techniques are presented, 1.:vith the scale of application, the labour cost, the consumables and cost of plal1L hire per day. These daLa have been used

'when available.

For the evaluations, the folloiving assumption ha\'e been uwde:

  • Daily working time: 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />
  • Weight ofpetro-diesei: 1 kg = 11976 litre The costs parameters used for the evaluation are:

~ Average Hourly Cost of manpo\ver in industry-: 21.59 EURO/h [4, p.300, France, 1995J

  • Purchase Price of Diesel oil: 0.2952 EURO/I [5, p.2X L Germany, 1995J
  • Purchase price of water: 15.5 FF/m' = 2.36 EURO/nf [6]

~ Purchase price ofsa.."'1d: 0.16 FF/k.g - 0.024 EURO/k.g l7J

  • Purchase Price of electricity: 0.2 FF/kWh = 0.03 EURO/kWh rSl 04.08.00 OAGI0001550_00006

For the values given in the NRPB report, the conversion in EURO v/as made using the average value per calendar year of the ECD published in h1.e EUROSTAT report on Agricultural price lSJ for 1996:

1 EURO = 0.813798 UK£ For the discount price of tools given in the RIS0 report in ECU the only "conversion" made was to change Eeu to EURO This document presents the detailed calculation in EURO/ha.

HO'wever, for all the technique, LCMT provides the surface which is assumed to be decontaminated in knf. \Vithin the data base, the unit cost of the various techniques \'viH be given in EURO/kn-f to tit \vith the LC~vfT uni 1s.

The total cost of each technique is evaluated on the basis of the followlng five parameters ,vhlch ",ill he lntegrated separately ln the data base, in order to facilitate its update:

  • Unit cos! or manpower (EURO/man-hour)

=- Manpower (man-hour/krrf)

  • Unit cost of consumable (EURO/km')
  • Unit cost of equipment (or investment) (EURO/knt) 04.08.00 OAGI0001550_00007

3 Skim and burial ploughing 3.1 Available Data The RIS0 report presents 2 techniques r1, p.50, 511:

  • Skin1 and burial plough and tractor: this technique allows to bury only a very thin layer (5 em) of topsoil at 45 em, and to have the 5-45 cm layer not inverted.
  • Skim and burial ploughing a!!mving an upper 5 em layer eut off and put w,dei ploughed hoii/.on oC soil.

The following data are provided vvhich will be used lor the cost evaluauon:

6 Grass Cutting 6.1 A vaHablc Data

6. I. I R1S0 report The RISe report ll, p.38J gives the follow-ing data for grass cutting wiLh a mlU1icipal pelrol driven lawn ffiO\ver wiib. seal, collecting grass in a vessel. Ii seems men to be applied to small areas:
  • D8jly Ma.l1pO\Ver: 1.3 10- 4 man-day/nr = 1.3 ma.n-day/ha
  • Discount Investment Cost: 3 000 EURO/year
  • Scale of application (surface vvhich cail be decontaminated \\ith one loo1): 1 000 nl/h x 720 h/year = 0.1 ha/h x 720 h/year = 72 halyear
  • Consumables (petro-diesel)* 6 IIh of petrol
6. J. 2 /VRPH report The NRPB report L2, p.19 J gives the total cost for grass cutting and collection technique applied to a unit o[ urban area surface [or small and large areas. The total costs summarised in the main table [2, Table
8. p.19] are the following:
  • Large areas: O.OOg £/m' gO £/ha for grass cutting with grass collection box.

~ Small areas: 0.4 £/nt - 4 000 £/11a for grass cutting \\*rit1. grass collection box.

Some other indications concerning the scale of application are b>:iven in the Appendix orthe report [2, p.74, 78]

Table 6,i. Unit parameters for grass cutting technique (NRPB)

Large areas Small areas (gardens)

Scale of application up to 10 000 ni Ih - 50 nr/h

- 4 gardens per day Labour cost £128 per 8 11 day £32 per garden

Other costs (plant hire per 5.9 10- 3 f/nr Plant hirc pcr day* f1 0 pcr day day plus consumable services, ConsLllTItlhlc:f5 per dny maintenance, spare)

Total cost 0.0075 £Inr 0.36 f/m 2 : 36 f/gardcn (this implicitly mcans ml average size of 100 Ht per garden)

F or the small areas, if we assume that 4 gardens can be decontaminated per day. and that the average size of a garden is 100 rrf. we obtain an 11 04.08.00 OAGI0001550_00013

average of 400 m' per day. The cost can then be expressed in £ per m' (or per hal:

  • Cost oCpla."'1t hire: £10 per day => 0.025 £inr = 250 £/ha
  • Consumable: £5 per day => 0.0125 £/m' = 125 £lha 2
  • Labour per garden: £32 per garden => 0.32 £/m = 3200 £/na (note: Summing all these costs gives approximately the same total cost per ~ thal1 the one presented in the main table, I.e., 0.4 £!~).

  • for snlall areas: 0.4 £/n]2 = 4000 £/11a = 4915.22 EURO/11a The assumption is made that for 'gra'ls cutting' the cost is an average betvveen s111al1 and 1arge areas (50~1o-50~/o). So the total cost is:

(98.30 x 0,5 + 4915.22 x 0.5) = 2506.76 EURO/ha

2. Est.imation of the total cost using the detailed data a.l-ld assum;ng a labour cost of 21.59 EUaO per hour (instead of the assunlption uf 16 £In, Le. 19.66 EURO/n)

16 Decontamination costs provided by NRPB in 1999 As Inentioned in the introduction, the NRPB has nlade, "viiith the UK lVllllistry of Defenl:e, a recent reVIew of decunlarninaLion and remediation techniques for Plutonium [3].

The follo\\1ng assumptIOns are made:

  • Conversion into EURO: 1 EURO = O.66g76 UK£ (1 S>99 rate)
  • Cost oflabour [or all countermeasures: 25 f/man.hour

= 38 EURG/man.hour This cost is for personnel \vorking in active areas. It is taken as a factor of 3 higher than commercial rates in non-radioactive areas

  • Costs or equipment include capital costs, depreciation, interest, (axes, insurance, storage and maintenance & repair.
  • Consumable costs do not include fuel and "\vatei costs. Ho\vever, where relevant, the qUEUltilies of water required per Hil are indicated.

17 Synthesis of data The data base [or evaluating costs o[ decontamination techniques conLains three parameLers per Lechniqu(;:

  • Unit cost of manpower (EURO/man-hour)
  • Unit cost of consumable (b URO/km')

.. Unit cost of equipment (EURO/kn-f)

The default data are those provided by NRPB in 1999 l3 J (see section 16).

Table 17.1 presents an the data coHected in RIS0 and NRPB reports (rounded values). The manpower required lor each technique is indicated lor infommtion, but it will not be included in ECONOM. It will be provided directly by LCMf. The default data for f nmnpower is 38 EURO/man.hour for each technique.

Table 172 presents the total cost of each technique (ElJROlkm'),

cEilculated from R1S0 !lnd NRPB (1996) reports. This cost is obt8ined by adding the ll.flit cost of m[mpmver (obt~ined '.vith a cost of ll1anpov,*'er of 21.6 EUROlma...'1.hr). th.e unit cost of consuIT'..ables and the unit cost of equipment.
